  • 1. ® IMS Version 12IMS Plays a Role in a System z Cloud © 2012 IBM Corporation
  • 2. IMS Version 12Memory lane1.Centralized Computing: 1960 – – Optimized for sharing, industrial strength, systems management, … – Managed by central IT organization – Back office applications involving transactions, shared data bases, … – Mainframes, supercomputers, minicomputers, …2.Client/Server: 1985 – – Optimized for low costs, simplicity, flexibility, … – Distributed management across multiple departments and organizations – Large numbers of PC-based applications – PC-based clients and servers, Unix, Linux, ...3.Cloud Computing: 2010 – – New consumption and delivery model – Optimized for massive scalability, delivery of services, … – Centralized model, hybrid service acquisition models – Supports huge numbers of mobile devices and sensors – Internet technology-based architecture 2
  • 3. IMS Version 12And the Evolution of Cloud Computing Grid Computing – leveraged several computers in parallel (clustered servers) to address a single problem or application Cloud Computing – leverages several resources to deliver a service to the end-user > Can support grids > Can support non-grid environments, e.g., 3-tiered web architecture with traditional or Web 2.0 applications 3
  • 4. IMS Version 12Cloud definitions– National Institute of Standards and Technology (NIST) defines a “cloud” as“a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources…that can be rapidly provisioned and released with minimal management effort or service provider interaction’’ Cloud computing • The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server 4
  • 5. IMS Version 12Cloud Computing is a Broad Term Line of Business IT Operations Common Cloud Attributes Elastic scaling Rapid provisioning Advanced virtualization Flexible pricing Service Oriented Public Clouds Private Clouds Cloud Computing is more than a computing model; it is a Service Delivery model 5
  • 6. IMS Version 12Service Management - at the Heart of the CloudDelivering Cloud services requires 2 components: Process Service Platform Processes • A Process Platform to manage the • Service Processes that deliver the user virtual infrastructure experience The effectiveness and efficiency of a cloud implementation is predicated on the interaction of these components 6
  • 7. IMS Version 12Additionally, Cloud Services Provide an environment that differs from traditional hosting due to three distinct characteristics – Services can be sold on demand • By the minute, hour, etc., – Services are elastic • A user can take advantage of as much or little access to services as needed at any given time – Services are fully managed by the provider • Consumers typically only need a personal computer and Internet access 7
  • 8. IMS Version 12When Building a Cloud Organizations choose a cloud model based on their business model requirements – Infrastructure as a service (IaaS) • Dynamically shared set of virtual computing resources – zEnterprise – Platform as a service (PaaS) • Builds on IaaS to provide application middleware – IMS – Software as a service (SaaS) • Provides higher levels of service delivery – IMS SOA Integration and Enterprise Suites – Business process as a service (BPaaS) • Customer-written applications or business processes 8
  • 9. IMS Version 12Cloud Deployment Models Public – Sells services to anyone on the Internet • e.g., Amazon Web Services • Consumer and Provider exist in separate enterprises – owned by an organization selling cloud services Private – Provides a proprietary network or a data center that supplies hosted services to a limited number of people. • Consumer and Provider exist within the same enterprise – operated solely for an organization – restructures IT around a services delivery model Hybrid or Heterogeneous – Combines Private and Public • Bound together by standardized technology that allows for portability 9
  • 10. IMS Version 12Cloud Deployment Models…Public cloud example – Amazon 2006, Amazon Web Services In Web Services (AWS) began offering IT infrastructure services to businesses in the form of web lets you provision a private, services isolated section of the Cloud where you can launch resources in a virtual network that you define. You can define a virtual network topology that closely resembles a traditional network that you might operate in your own datacenter. Allows business to run their Websites, blogs, etc run all types of enterprise applications, from small departmental solutions to mission-critical applications that automate company-wide business processes. For personal computing -- allows you to have a personal hard drive in the cloud 10
  • 11. IMS Version 12Cloud Deployment Models…Public cloud example – IBM Smart Cloud 11
  • 12. IMS Version 12IBM System zCloud Value of cloud computing is the availability of infrastructure …. Enterprises are beginning to recognized that the maximum value of cloud-based solutions includes interconnection to their existing business infrastructure System z is a natural Cloud Platform – zEnterprise 196 and 114 • central processing complex – zEnterprise BladeCenter Extension (zBX) • high-performance specialty processors for specific workloads – zEnterprise Unified Resource Manager • end-to-end platform integration and resource optimization 12
  • 13.
