Editor's Notes
- #4 Points worth remembering: Software-as-a-service (SaaS) allows small or medium size businesses to subscribe to an application it can access over the Internet. Platform-as-a-service (PaaS) allows businesses to create a customized application for use throughout the company. A business may create and deploy custom apps, databases, and a line of business services, which have been integrated into a singular platform. Infrastructure-as-a-service (IaaS) can be rented out by companies to other companies. Benefits of utilizing the Cloud are the ability to transfer the management/operational services of complex systems/applications, cost efficiency, reduced internal hardware/software, and allow for increased computing services on a broader range. Problems with utilizing cloud computing services are the control of access by ISPs, Telcos, and media companies, and the increased costs with increased use of bandwidth. It is highly likely that when a crash occurs at the cloud service provider (CSP) level it will affect all the companies that use the services of this provider. In addition, there is no central governing body over the use of the Cloud. Although there are standards created by the Institute of Electrical and Electronics Engineers (IEEE) in 2011. The best protection for businesses is to ensure that the SLA contains language of specific compliance to IEEE standards by the CSP. (Griffith, 2015)
- #5 Question: What are technology service of which the “cloud” is comprised? Answer: Technology services are delivered based upon business requirements which range from internet connectivity to enterprise application software. These services include, but are not limited to, Web-design/development, IT/Network services, Cloud computing, Information security, and/or Mobile services. The path to migrating success will have a significant impact on vendor selection and ultimately cost. Search for experienced professionals inside/outside the business to get the best objective advice. Plan migration in a linear path from PC solution to cloud solution. The plan is a process that should be implemented in steps over a period of time. Utilizing the cloud brings the following benefits to an organization: All you need is Internet access, browser, tablet, and/or mobile phone to access your data and programs in the cloud. Devices that access the cloud do not require the processing power to run local complex applications, and the devices in most cases are cheaper. IT support costs are reduced with the reduction in desktops, servers, and software. Reduction in office space. Elimination of filing cabinets to store software source CDs and upgrades. Cloud computing providers are familiar/equipped to address most compliance needs. Problems associated with cloud computing: Companies have suffered security breaches, but cloud computing vendors are strongly incentivized to keep data secure. Possibility that the user's data can be compromised. In order to reach more people, the richness must be reduced meaning that Web applications minimize the data being presented and manipulated to increase speed, resulting in decreased functionality compared with a PC-based product. Offices typically have to increase bandwidth to accommodate the increased demand, resulting in raising costs. (Huxford, 2012)
- #6 Yet another definition of cloud computing: The cloud is considered a parallel/distributed computing system that consists of a collection of inter-connected computers on the Web, which are dynamically provisioned and presented as one (a unified computing resources) based on established negotiation of the SLA between the service provider and consumers. Points for remembering: The cloud becomes an adaptive infrastructure shared by various end users, each of whom might use it differently. The flexibility of the infrastructure allows for computing loads to be balanced on demand as more users join the system. As the number of users goes up, the demand load on the system becomes more balanced, even as its economies of scale expand. The goal of cloud computing is to scale resources up or down dynamically through software APIs. Important take away: Mobile interactive applications that are aware of location, environment, and context are capable of responding in real time to information provided by users. So sales data can be remotely tracked/data specific to regions throughout the organization. Another example of how the cloud can foster the current business objective: Companies have made considerable progress toward standardizing their processes, data, and systems through implementation of ERPs. This has enabled scalable infrastructures to create single instances, or highly integrated connections between instances, to manage the consistency of master/transaction data while producing reliable consolidated information. (Avram, 2014)
- #7 This slide reviews the findings from an annual survey of EA use among CIOs, Chief Architects, and Business and IT managers. The survey’s aim was to understand then explain how EA may benefit organizations and how it is integrated with other organizational activities like strategic business planning, enterprise, and IT governance. (Tamm, Seddon, Shanks, & Reynolds, 2011)
- #8 In review of the 2nd case study, this slide lists eight of the nineteen benefits of EA from an academic study SIM EA Survey, 2007. Additionally key points in the article were: The key purpose of EA is to guide the building of an improved operating platform (IT systems/digitized business processes that support or automate an organization's core capabilities). EA enables an enterprise to achieve improved information flows and reduced IT costs. EA‘s impact on benefits that are contingent on implementation is somewhat weaker than on benefits that can be derived from the EA plans directly. The term, ‘benefit enablers’ emphasizes that some EA outcomes are not benefits per se, but are factors which have been demonstrated in earlier research to have a high potential for enabling organizational benefits.
- #9 Additional benefits that are desirable for a sales department network: CSPs are typically transparent with the organizations they service about security measures taken. Cloud resources can be rapidly and elastically scaled. Resources can be scaled either up or down while delivering dynamic performance. Used services are metered and reported to both customers and CSP. Customers can request/manage cloud services without human interaction with the CSP. Services, applications, and data are accessible to customers using standard mechanisms and protocols. The cloud’s services are made available to mobile phones, laptops, tablets and/or workstations. (Ali, Khan, & Vasilakos, 2014)
- #10 Define/explain the categories of service: SaaS enables customers to use CSP’s applications which run on the cloud infrastructure through the Internet. This type of interface can be used to access various applications (i.e. Web browser). 2. The applications owned by customers (i.e. integrated development environments (IDE), operating systems, and platform layer resources) need a framework where they can be executed and managed. PaaS provide customers with control over the applications that are moved to the cloud. 3. The IaaS is hardware infrastructure provided by the CSP including the network, storage, memory, processor, and various other computing resources. The resources are provided in the form of virtualized systems accessible through Internet. (Ali, Khan, & Vasilakos, 2014)
- #11 To address the issue of security, which is every cloud user’s concern author’s Wei, Zhu, Cao, Dong, Jia, Chen, & Vasilakos (2014) propose the following: Design/create a basic protocol relying on the identity-based cryptography. The proposed protocol consists of four phases: ‘‘system initialization’’, ‘‘secure cloud storage’’, ‘‘secure cloud computation’’, and ‘‘computation result auditing’’. SecCloud, a privacy-cheating discouragement and secure-computation auditing protocol for data security in the cloud, is proposed. Study shows that SecCloud can attain data storage security and computation auditing security as well as privacy cheating discouragement and an advanced protocol to achieve computation and communication efficiency improvement through batch verification.
- #12 Three valid concerns with cloud services: How can/does the cloud protect individual and/or propriety information? There must be consideration/planning for how technology will affect the IT role. CSPs may be unable to guarantee the location of information on a specified set of servers within a specified location. (Avram, 2014).
- #13 The two foremost concerns when deciding to use the cloud’s services are (1) drafting the SLA and (2) the effects of the service to propriety information and assets. Prior to selecting a vendor, there should be ample planning to ensure that the business objectives are clearly outlined with clear concise language in the SLA. Selecting a knowledgeable diverse team to work on the project will serve to be valuable when its time to select a vendor and create the SLA. Being aware of how propriety assets will be handled and secured by the CSP is essential across all areas of the endeavor. Knowing what to expect, what is common practice, and limitations of the vendor/services will help foster a better working relationship between the business and CSP. (Avram, 2014)
