7.1 Logical Network Perimeter Logical Network Perimeter Defined as the isolation of a network environment from the rest of a communications network, the logical network perimeter establishes a virtual network boundary that can encompass and isolate a group of related cloud-based IT resources that may be physically distributed This mechanism can be implemented to: isolate IT resources in a cloud from non-authorized users isolate IT resources in a cloud from non-users isolate IT resources in a cloud from cloud consumers control the bandwidth that is available to isolated IT resources Logical Network Perimeter Logical network perimeters are typically established via network devices that supply and control the connectivity of a data center and are commonly deployed as virtualized IT environments that include: • Virtual Firewall – An IT resource that actively filters network traffic to and from the isolated network while controlling its interactions with the Internet. • Virtual Network – Usually acquired through VLANs, this IT resource isolates the network environment within the data center infrastructure.
7.2 Virtual Server Virtual Server A virtual server is a form of virtualization software that emulates a physical server. Virtual servers are used by cloud providers to share the same physical server with multiple cloud consumers by providing cloud consumers with individual virtual server instances. Virtual Server 7.3 Cloud Storage Device Cloud Storage Device The cloud storage device mechanism represents storage devices that are designed specifically for cloud-based provisioning. Instances of these devices can be virtualized, similar to how physical servers can spawn virtual server images
Cloud Storage Levels Cloud storage device mechanisms provide common logical units of data storage, such as: • Files – Collections of data are grouped into files that are located in folders. • Blocks – The lowest level of storage and the closest to the hardware, a block is the smallest unit of data that is still individually accessible. • Datasets – Sets of data are organized into a table-based, delimited, or record format. • Objects – Data and its associated metadata are organized as Web-based resources. Network Storage Interfaces Object Storage Interfaces database storage interfaces Relational Data Storage Non-Relational Data Storage 7.4 Cloud Usage Monitor Parent monitoring mechanism Monitoring agent Resource agent Polling agent

READY-MADE ENVIRONMENT Is a defining component of the PaaS cloud delivery model that represents a pre-defined, cloud-based platform comprised of a set of already installed IT resources. Typical pre-installed IT resources are: Databases Middleware Development tools Governance tools READY-MADE ENVIRONMENT Business and Technical Perspectives of Cloud Mechanisms Specialized Cloud Mechanisms Chapter 8 Cloud CharacteristicsCloud Mechanisms On – Demand UsageHypervisorVirtual ServerReady-Made EnvironmentResource ReplicationRemote Administration EnvironmentResource Management SystemSLA Management SystemBilling Management SystemUbiquitous AccessLogical Network PerimeterMulti-Device Broker Multitenancy / Resource PoolingLogical Network PerimeterHypervisorResource ReplicationResource

exceed or fall below thresholds Load Balancer A common approach to horizontal scaling is to balance workload across two or more IT resources Goal is to increase performance Can perform specialized work load distribution functions: Asymmetric Workload Prioritization Content-Aware Distribution Load Balancer Have configured set of performance and QoS rules for optimizing performance for IT resources Located between the IT Resource generating and performing the workload Can be hidden from the cloud consumers SLA Monitor Observes the runtime performance of cloud services that are fulfilling the contractual QoS requirements Data collected by the monitor is process by the SLA management system to be aggregated into SLA reporting metrics The system can proactively repair or failover cloud services Pay-Per-Use Monitor Measures cloud-based IT resources usage in accordance with predefined pricing parameters Typical monitoring variables are: Request / response message quantity
Transmitted data volume Bandwidth consumption Data collected by the pay-per-user monitor is processed by a billing management system Audit Monitor Collects audit tracking data for networks and IT resources in support of regulatory and contractual obligations Failover System Increase reliability and availability of IT resources Is configured to automatically switch over to a redundant or standby IT resource Are commonly used for mission critical programs and reusable services that can introduce a single point of failure The resource replication mechanism is sometimes utilized by the failover system Failovers two basic configurations: Active – Active, redundant implementations of the IT resources – synchronously Active – Passive, standby or inactive implementation is activated Hypervisor Used to generate virtual server instances of a physical server Limited to one physical server Hypervisors have limited virtual server management features Hypervisor software can be installed directly in bare metal servers Resource Cluster
Cloud-based IT resources that are geographically diverse can be logically combined into groups to improve allocation and use Groups multiple IT resources so they can operate as one - This increases: Computing capacity Load balancing Availability Resource Cluster Common resource cluster types: Server Cluster Database Cluster Large Dataset Cluster Two basic resource clusters: Load Balanced High Availability Provision of cluster is more expensive than a single IT resource Multi-Device Broker Mechanism use to facilitate runtime data transformation so as to make a cloud service accessible to a wider range of cloud service consumer programs and devices Mutli-device brokers commonly exist as gateways or incorporate gateway components such as: XML Cloud stage gateway Mobile device gateway State Management Database Is a storage device that is used to temporarily persist state data for software programs.
Is an alternative to caching state data in memory Chapter 9. Cloud Management Mechanisms Chapter 9. Cloud Management Mechanisms 9.1 Remote Administration System 9.2 Resource Management System 9.3 SLA Management System 9.4 Billing Management System Remote Administration System The remote administration system mechanism (Figure 9.1) provides tools and user-interfaces for external cloud resource administrators to configure and administer cloud-based IT resources Remote Administration System Two primary types of portals created with the Remote Administration System: Usage and Administration Portal Self-Service Portal
Remote Administration System Usage and Administration Portal – A general purpose portal that centralizes management controls to different cloud-based IT resources and can further provide IT resource usage reports. Remote Administration System Self-Service Portal – This is essentially a shopping portal that allows cloud consumers to search an up-to-date list of cloud services and IT resources that are available from a cloud provider (usually for lease). The cloud consumer submits its chosen items to the cloud provider for provisioning Tasks that can commonly be performed by cloud consumers via a remote administration console include: • configuring and setting up cloud services • provisioning and releasing IT resource for on-demand cloud services • monitoring cloud service status, usage, and performance • monitoring QoS and SLA fulfillment • managing leasing costs and usage fees • managing user accounts, security credentials, authorization, and access control • tracking internal and external access to leased services • planning and assessing IT resource provisioning • capacity planning
Resource Management System The resource management system mechanism helps coordinate IT resources in response to management actions performed by both cloud consumers and cloud providers Core to this system is the virtual infrastructure manager (VIM) that coordinates the server hardware so that virtual server instances can be created from the most expedient underlying physical server. A VIM is a commercial product that can be used to manage a range of virtual IT resources across multiple physical servers. For example, a VIM can create and manage multiple instances of a hypervisor across different physical servers or allocate a virtual server on one physical server to another (or to a resource pool). Resource management system functions can be accessed by cloud resource administrators employed by the cloud provider or cloud consumer. Those working on behalf of a cloud provider will often be able to directly access the resource management system’s native console. SLA Management System The SLA management system mechanism represents a range of commercially available cloud management products that provide
features pertaining to the administration, collection, storage, reporting, and runtime notification of SLA data An SLA management system deployment will generally include a repository used to store and retrieve collected SLA data based on pre-defined metrics and reporting parameters. It will further rely on one or more SLA monitor mechanisms to collect the SLA data that can then be made available in near-real time to usage and administration portals to provide on-going feedback regarding active cloud services A cloud service consumer interacts with a cloud service (1). An SLA monitor intercepts the exchanged messages, evaluates the interaction, and collects relevant runtime data in relation to quality-of-service guarantees defined in the cloud service’s SLA (2A). The data collected is stored in a repository (2B) that is part of the SLA management system (3). Queries can be issued and reports can be generated for an external cloud resource administrator via a usage and administration portal (4) or for an internal cloud resource administrator via the SLA management system’s native user-interface (5). BILLING MANAGEMENT SYSTEM The billing management system mechanism is dedicated to the collection and processing of usage data as it pertains to cloud provider accounting and cloud consumer billing. Specifically, the billing management system relies on pay-per-use monitors to gather runtime usage data that is stored in a repository that the system components then draw from for billing, reporting, and invoicing purposes
A cloud service consumer exchanges messages with a cloud service (1). A pay-per-use monitor keeps track of the usage and collects data relevant to billing (2A), which is forwarded to a repository that is part of the billing management system (2B). The system periodically calculates the consolidated cloud service usage fees and generates an invoice for the cloud consumer (3). The invoice may be provided to the cloud consumer through the usage and administration portal (4). A Business Case for Google Apps for Education Problem Statement Goldfarb School of Nursing (GSON)’s lack of technology enhancement is a weakness. This weakness causes problems with: accreditation organizations, students’ satisfaction, aspiring nurse preparation, budget management, student retention, and student recruitment. Analysis of Situation BJC’s GroupWise email and messenger limit communication and collaboration among GSON stakeholders. GroupWise Messenger is not accessible outside the organization firewall, nor are students able to connect to the organization’s email system using a mobile device without incurring a cost. Because instant communication is lost and external communication is limited, students may be dissatisfied. Student dissatisfaction may have an effect on student retention, student recruitment, and the reputation of the organization. Moreover, the technology enhancements could allow better user experiences, like students learning in the way they want to learn, with technology. Beyond email and messenger, other innovative communication mediums exist. Documents can be shared and collaborated on
in real time and videos can be shared, as with YouTube. These same approaches can be used in an educational environment to enhance operational efficiency as well as teaching and learning. Document sharing would allow students to collaborate with their peers and professors on projects or homework assignments. Video sharing can be used for nurse preparation, student orientation, or to share information related to drug or alcohol abuse, which is a compliance requirement for Title IX. Because GSON is limited by the lack of technology enhancements, third party solutions have been considered for procurement. For example, Mediacore, a video sharing product, was reviewed. The purpose of the product would be to share videos among different stakeholders throughout the College. Various departments would have the ability to share videos. While this is a great tool, as you will see in the cost benefit analysis section of this document, sound fiscal management would be remiss. The Higher Learning Commission (HLC), an accrediting body of the College, requires a plan for innovation and technology. 1. Criterion/standard 5.C.5 states: Institutional planning anticipates emerging factors, such as technology, demographic shifts, and globalization. 2. Criterion/standard 3.D.4. states: The institution provides to students and instructors the infrastructure and resources necessary to support effective teaching and learning (technological infrastructure, scientific laboratories, libraries, performance spaces, clinical practice sites, museum collections, as appropriate to the institution’s offerings). To address the problems presented in this business case, Google Apps for Education is recommended. Solution
The solution to the problems presented in this business case is to implement Google Apps for Education (GAE). GAE is chosen because it addresses the main problem and sub-problems initially presented in this business case. Student mobile access - The issue of mobile access for students will be addressed because this platform allows for access at no cost to students. This solution also mitigates BJC’s risk because stakeholders’ email will not be going through the main email system. Increases stakeholders’ use and return on investment (ROI) - The benefit is twofold. We hope to capitalize on stakeholders’ prior knowledge and use of Google Apps that way we increase our return on investment. The ROI would be faster because time to full implementation would be less. Purchase of third party platforms -Google Apps for Education provides similar solutions to those we are seeking from third party vendors. This allows us (Administration) to be good stewards of our budget. Mission of College/Teaching and Learning - Teaching and learning / nurse preparation is why we exist. Today’s students are tech savvy and want to learn that way. To that end, this solution addresses this problem because it provides a platform for 21st century teaching and learning to take place. In addition, because of our ability to better prepare aspiring
nurses, there may be a positive impact on the College’s reputation that would help sustain and increase our market share and create a competitive advantage. Accreditation – This problem is addressed by GAE creating an environment that provides students and instructors the infrastructure and resources necessary to support effective teaching and learning. Table 1 is a snapshot of how Google Apps for Education addresses the problems presented in this business case by app. Table 1 Current Structure vs. Google Apps for Education with benefits Applications Current Structure Google Apps for Education Benefits Email X X Adds familiar platform stakeholders know – increase use / ROI Email mobile access X – cost for students X
No cost to students Messenger X – not external X Increases communication by adding external access Video Conference – Google Hangout X Eliminates need for third party platform / decrease budget implications Shared Documents anytime /anywhere X Increases collaboration among stakeholders Video Sharing X Eliminates need for third party platform / decrease budget implications Calendar X X Increases use among stakeholders because users have prior knowledge of the system Appointments
X Eliminates need for third party platform / decrease budget implications Implementation To implement this solution change would have to take place from structural, human resource, political, and symbolic perspectives. Structural To implement this project the following platforms or utilities will be needed: Google Apps for Education (GAE) - is the platform that allows us access to the different apps that address the problems presented in this case. Google Active Directory (GADS) – is a utility provided by Google that allows user accounts to be created using automation. At a given time, the GADS tool will execute by looking inside of the designated OU in Active Directory. Then, any changes will be synced with GAE. This process is encrypted. Google Apps Password Sync (GAPS) – is a utility provided by Google that automatically keeps your users’ Google Apps
passwords in sync with their Active Directory passwords. Whenever a user's Active Directory password is changed, GAPS pushes the change to Google Apps immediately Active Directory (AD) – AD is used throughout the organization for access control. Our students complete clinical experiences throughout the BJC system; therefore, they still need network access. For Google Apps for Education, we would need a student’s “mail” attribute to end in barnesjewishcollege.edu. Domain Name Services – In the domain control panel for barnesjewishcollege.edu, the MX record would need to be changed to point to Google’s mail servers. These mail servers are provided once we are approved by Google. We would also need the CNAME setup that points to webmail.barnesjewishcollege.edu. Website – The website is used to verify the barnesjewishcollege.edu domain. Additional Deployment Information: https://docs.google.com/document/d/1ixVHcT85nhaU8yYUzi4S EaEMocqkRSSC_Y5GpUtUCVI/edit Human Resources At this point, no new employees are needed; however, technical and non-technical stakeholders will be affected by this change. The technical stakeholders are: 1. BJC IS Security – We will need them to make sure that the risk to BJC infrastructure will not be compromised.
2. BJC IS Email Server Group – We will need this group to make sure our approach to adding GAE as an email platform will not interfere with GroupWise. 3. BJC IS Domain Name Services Group – We will need this group to make the domain changes to the barnesjewishcollege.edu domain. 4. BJC IS Help Desk Group – This group will need to understand how to help a student calling for support due to migrating over to GAE. 5. GSON – Angela Trower – She has access to make changes to the College’s website. 6. GSON – Information Systems – Information Systems will need to understand the technology implications as they relates to GAE. 7. GSON - Instructional Technology – Instructional Technology would be responsible for communicating the change and developing a student and faculty training program. 8. GSON - Administrators, Faculty, Staff, and Students Political The two key political areas that need to be addressed are: 1. BJC IS approval to implement the proposed solution. 2. GSON stakeholders’ attitude toward change. To address issue one, this business case has been submitted, and we are having monthly meetings with BJC IS to work through the details and build relationships. Issue two will be addressed
by developing a communication and training plan that addresses GSON stakeholders’ concerns. Symbolic Part of the communication plan created by the Instructional Technology department will mentioned how making this change prepares the college for future and allows 21st Century teaching and learning. Change champions would also be identified to help with this transition. Cost benefit analysis (CBA) The cost benefit analysis includes quantitative and qualitative benefits. Quantitative Benefits The cost for not changing our current practice will be a $66,118 initial investment. Every year after until year 5 will cost 49% of the initial investment or $32,728. Year 5, the cost will increase due to the SharePoint server equipment replacement cycle. See tables below. This CBA does not include labor; however Google Apps compared to our given structure (GroupWise) and third party applications is the most appropriate. The fact that GAE is free is not the only reason for this choice. GAE meets our needs. Table 2 Current Structure with Third Party Calculations Applications & Hardware

$1728 $1728 $1728 Annually TOTAL $66,118 $32,728 $32,728 Annually Qualitative benefits The qualitative benefits gained from this implementation are satisfied students and increased student learning outcomes. These qualitative benefits also have a positive effect on data required by the accreditation agencies, student recruitment, and GSON’s reputation. Total Cost of Ownership I do not have the labor costs; therefore, I could not determine the TCO. Conclusion - What is the impact of not implementing this new application?
The price for not addressing these problems presented in this case study may have an effect on the College: 1. Accreditation; 2. Student experience and satisfaction; 3. Market share and competitive advantage; 4. Over spending; and 5. Antiquated teaching practices. G.1.

    7.1 Logical NetworkPerimeter Logical Network Perimeter Defined as the isolation of a network environment from the rest of a communications network, the logical network perimeter establishes a virtual network boundary that can encompass and isolate a group of related cloud-based IT resources that may be physically distributed This mechanism can be implemented to: isolate IT resources in a cloud from non-authorized users isolate IT resources in a cloud from non-users isolate IT resources in a cloud from cloud consumers control the bandwidth that is available to isolated IT resources Logical Network Perimeter Logical network perimeters are typically established via network devices that supply and control the connectivity of a data center and are commonly deployed as virtualized IT environments that include: • Virtual Firewall – An IT resource that actively filters network traffic to and from the isolated network while controlling its interactions with the Internet. • Virtual Network – Usually acquired through VLANs, this IT resource isolates the network environment within the data center infrastructure.
  • 4.
    7.2 Virtual Server VirtualServer A virtual server is a form of virtualization software that emulates a physical server. Virtual servers are used by cloud providers to share the same physical server with multiple cloud consumers by providing cloud consumers with individual virtual server instances. Virtual Server 7.3 Cloud Storage Device Cloud Storage Device The cloud storage device mechanism represents storage devices that are designed specifically for cloud-based provisioning. Instances of these devices can be virtualized, similar to how physical servers can spawn virtual server images
  • 5.
    Cloud Storage Levels Cloudstorage device mechanisms provide common logical units of data storage, such as: • Files – Collections of data are grouped into files that are located in folders. • Blocks – The lowest level of storage and the closest to the hardware, a block is the smallest unit of data that is still individually accessible. • Datasets – Sets of data are organized into a table-based, delimited, or record format. • Objects – Data and its associated metadata are organized as Web-based resources. Network Storage Interfaces Object Storage Interfaces database storage interfaces Relational Data Storage Non-Relational Data Storage 7.4 Cloud Usage Monitor Parent monitoring mechanism Monitoring agent Resource agent Polling agent

Cloud Management Mechanisms 9.1 Remote Administration System 9.2 Resource Management System 9.3 SLA Management System 9.4 Billing Management System Remote Administration System The remote administration system mechanism (Figure 9.1) provides tools and user-interfaces for external cloud resource administrators to configure and administer cloud-based IT resources Remote Administration System Two primary types of portals created with the Remote Administration System: Usage and Administration Portal Self-Service Portal
  • 13.
    Remote Administration System Usageand Administration Portal – A general purpose portal that centralizes management controls to different cloud-based IT resources and can further provide IT resource usage reports. Remote Administration System Self-Service Portal – This is essentially a shopping portal that allows cloud consumers to search an up-to-date list of cloud services and IT resources that are available from a cloud provider (usually for lease). The cloud consumer submits its chosen items to the cloud provider for provisioning Tasks that can commonly be performed by cloud consumers via a remote administration console include: • configuring and setting up cloud services • provisioning and releasing IT resource for on-demand cloud services • monitoring cloud service status, usage, and performance • monitoring QoS and SLA fulfillment • managing leasing costs and usage fees • managing user accounts, security credentials, authorization, and access control • tracking internal and external access to leased services • planning and assessing IT resource provisioning • capacity planning
  • 14.
    Resource Management System Theresource management system mechanism helps coordinate IT resources in response to management actions performed by both cloud consumers and cloud providers Core to this system is the virtual infrastructure manager (VIM) that coordinates the server hardware so that virtual server instances can be created from the most expedient underlying physical server. A VIM is a commercial product that can be used to manage a range of virtual IT resources across multiple physical servers. For example, a VIM can create and manage multiple instances of a hypervisor across different physical servers or allocate a virtual server on one physical server to another (or to a resource pool). Resource management system functions can be accessed by cloud resource administrators employed by the cloud provider or cloud consumer. Those working on behalf of a cloud provider will often be able to directly access the resource management system’s native console. SLA Management System The SLA management system mechanism represents a range of commercially available cloud management products that provide
  • 15.
    features pertaining tothe administration, collection, storage, reporting, and runtime notification of SLA data An SLA management system deployment will generally include a repository used to store and retrieve collected SLA data based on pre-defined metrics and reporting parameters. It will further rely on one or more SLA monitor mechanisms to collect the SLA data that can then be made available in near-real time to usage and administration portals to provide on-going feedback regarding active cloud services A cloud service consumer interacts with a cloud service (1). An SLA monitor intercepts the exchanged messages, evaluates the interaction, and collects relevant runtime data in relation to quality-of-service guarantees defined in the cloud service’s SLA (2A). The data collected is stored in a repository (2B) that is part of the SLA management system (3). Queries can be issued and reports can be generated for an external cloud resource administrator via a usage and administration portal (4) or for an internal cloud resource administrator via the SLA management system’s native user-interface (5). BILLING MANAGEMENT SYSTEM The billing management system mechanism is dedicated to the collection and processing of usage data as it pertains to cloud provider accounting and cloud consumer billing. Specifically, the billing management system relies on pay-per-use monitors to gather runtime usage data that is stored in a repository that the system components then draw from for billing, reporting, and invoicing purposes
  • 16.
    A cloud serviceconsumer exchanges messages with a cloud service (1). A pay-per-use monitor keeps track of the usage and collects data relevant to billing (2A), which is forwarded to a repository that is part of the billing management system (2B). The system periodically calculates the consolidated cloud service usage fees and generates an invoice for the cloud consumer (3). The invoice may be provided to the cloud consumer through the usage and administration portal (4). A Business Case for Google Apps for Education Problem Statement Goldfarb School of Nursing (GSON)’s lack of technology enhancement is a weakness. This weakness causes problems with: accreditation organizations, students’ satisfaction, aspiring nurse preparation, budget management, student retention, and student recruitment. Analysis of Situation BJC’s GroupWise email and messenger limit communication and collaboration among GSON stakeholders. GroupWise Messenger is not accessible outside the organization firewall, nor are students able to connect to the organization’s email system using a mobile device without incurring a cost. Because instant communication is lost and external communication is limited, students may be dissatisfied. Student dissatisfaction may have an effect on student retention, student recruitment, and the reputation of the organization. Moreover, the technology enhancements could allow better user experiences, like students learning in the way they want to learn, with technology. Beyond email and messenger, other innovative communication mediums exist. Documents can be shared and collaborated on
  • 17.
    in real timeand videos can be shared, as with YouTube. These same approaches can be used in an educational environment to enhance operational efficiency as well as teaching and learning. Document sharing would allow students to collaborate with their peers and professors on projects or homework assignments. Video sharing can be used for nurse preparation, student orientation, or to share information related to drug or alcohol abuse, which is a compliance requirement for Title IX. Because GSON is limited by the lack of technology enhancements, third party solutions have been considered for procurement. For example, Mediacore, a video sharing product, was reviewed. The purpose of the product would be to share videos among different stakeholders throughout the College. Various departments would have the ability to share videos. While this is a great tool, as you will see in the cost benefit analysis section of this document, sound fiscal management would be remiss. The Higher Learning Commission (HLC), an accrediting body of the College, requires a plan for innovation and technology. 1. Criterion/standard 5.C.5 states: Institutional planning anticipates emerging factors, such as technology, demographic shifts, and globalization. 2. Criterion/standard 3.D.4. states: The institution provides to students and instructors the infrastructure and resources necessary to support effective teaching and learning (technological infrastructure, scientific laboratories, libraries, performance spaces, clinical practice sites, museum collections, as appropriate to the institution’s offerings). To address the problems presented in this business case, Google Apps for Education is recommended. Solution
  • 18.
    The solution tothe problems presented in this business case is to implement Google Apps for Education (GAE). GAE is chosen because it addresses the main problem and sub-problems initially presented in this business case. Student mobile access - The issue of mobile access for students will be addressed because this platform allows for access at no cost to students. This solution also mitigates BJC’s risk because stakeholders’ email will not be going through the main email system. Increases stakeholders’ use and return on investment (ROI) - The benefit is twofold. We hope to capitalize on stakeholders’ prior knowledge and use of Google Apps that way we increase our return on investment. The ROI would be faster because time to full implementation would be less. Purchase of third party platforms -Google Apps for Education provides similar solutions to those we are seeking from third party vendors. This allows us (Administration) to be good stewards of our budget. Mission of College/Teaching and Learning - Teaching and learning / nurse preparation is why we exist. Today’s students are tech savvy and want to learn that way. To that end, this solution addresses this problem because it provides a platform for 21st century teaching and learning to take place. In addition, because of our ability to better prepare aspiring
  • 19.
    nurses, there maybe a positive impact on the College’s reputation that would help sustain and increase our market share and create a competitive advantage. Accreditation – This problem is addressed by GAE creating an environment that provides students and instructors the infrastructure and resources necessary to support effective teaching and learning. Table 1 is a snapshot of how Google Apps for Education addresses the problems presented in this business case by app. Table 1 Current Structure vs. Google Apps for Education with benefits Applications Current Structure Google Apps for Education Benefits Email X X Adds familiar platform stakeholders know – increase use / ROI Email mobile access X – cost for students X

    X Eliminates need forthird party platform / decrease budget implications Implementation To implement this solution change would have to take place from structural, human resource, political, and symbolic perspectives. Structural To implement this project the following platforms or utilities will be needed: Google Apps for Education (GAE) - is the platform that allows us access to the different apps that address the problems presented in this case. Google Active Directory (GADS) – is a utility provided by Google that allows user accounts to be created using automation. At a given time, the GADS tool will execute by looking inside of the designated OU in Active Directory. Then, any changes will be synced with GAE. This process is encrypted. Google Apps Password Sync (GAPS) – is a utility provided by Google that automatically keeps your users’ Google Apps
  • 22.
    passwords in syncwith their Active Directory passwords. Whenever a user's Active Directory password is changed, GAPS pushes the change to Google Apps immediately Active Directory (AD) – AD is used throughout the organization for access control. Our students complete clinical experiences throughout the BJC system; therefore, they still need network access. For Google Apps for Education, we would need a student’s “mail” attribute to end in barnesjewishcollege.edu. Domain Name Services – In the domain control panel for barnesjewishcollege.edu, the MX record would need to be changed to point to Google’s mail servers. These mail servers are provided once we are approved by Google. We would also need the CNAME setup that points to webmail.barnesjewishcollege.edu. Website – The website is used to verify the barnesjewishcollege.edu domain. Additional Deployment Information: https://docs.google.com/document/d/1ixVHcT85nhaU8yYUzi4S EaEMocqkRSSC_Y5GpUtUCVI/edit Human Resources At this point, no new employees are needed; however, technical and non-technical stakeholders will be affected by this change. The technical stakeholders are: 1. BJC IS Security – We will need them to make sure that the risk to BJC infrastructure will not be compromised.
  • 23.
    2. BJC ISEmail Server Group – We will need this group to make sure our approach to adding GAE as an email platform will not interfere with GroupWise. 3. BJC IS Domain Name Services Group – We will need this group to make the domain changes to the barnesjewishcollege.edu domain. 4. BJC IS Help Desk Group – This group will need to understand how to help a student calling for support due to migrating over to GAE. 5. GSON – Angela Trower – She has access to make changes to the College’s website. 6. GSON – Information Systems – Information Systems will need to understand the technology implications as they relates to GAE. 7. GSON - Instructional Technology – Instructional Technology would be responsible for communicating the change and developing a student and faculty training program. 8. GSON - Administrators, Faculty, Staff, and Students Political The two key political areas that need to be addressed are: 1. BJC IS approval to implement the proposed solution. 2. GSON stakeholders’ attitude toward change. To address issue one, this business case has been submitted, and we are having monthly meetings with BJC IS to work through the details and build relationships. Issue two will be addressed
  • 24.
    by developing acommunication and training plan that addresses GSON stakeholders’ concerns. Symbolic Part of the communication plan created by the Instructional Technology department will mentioned how making this change prepares the college for future and allows 21st Century teaching and learning. Change champions would also be identified to help with this transition. Cost benefit analysis (CBA) The cost benefit analysis includes quantitative and qualitative benefits. Quantitative Benefits The cost for not changing our current practice will be a $66,118 initial investment. Every year after until year 5 will cost 49% of the initial investment or $32,728. Year 5, the cost will increase due to the SharePoint server equipment replacement cycle. See tables below. This CBA does not include labor; however Google Apps compared to our given structure (GroupWise) and third party applications is the most appropriate. The fact that GAE is free is not the only reason for this choice. GAE meets our needs. Table 2 Current Structure with Third Party Calculations Applications & Hardware

These qualitative benefits also have a positive effect on data required by the accreditation agencies, student recruitment, and GSON’s reputation. Total Cost of Ownership I do not have the labor costs; therefore, I could not determine the TCO. Conclusion - What is the impact of not implementing this new application?
  • 29.
    The price fornot addressing these problems presented in this case study may have an effect on the College: 1. Accreditation; 2. Student experience and satisfaction; 3. Market share and competitive advantage; 4. Over spending; and 5. Antiquated teaching practices. G.1.
