2 Memory lane 1.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

And the Evolution of Cloud Computing Grid Computing leveraged several computers in parallel (clustered servers) to address a single problem or application Cloud Computing leverages

3 And 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 Cloud 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 Cloud Computing is a Broad Term Line of Business IT Operations Common Cloud Attributes Elastic scaling Rapid provisioning Advanced virtualization Flexible pricing Service Oriented 5 Public Clouds Cloud Computing is more than a computing model; it is a Service Delivery model Private Clouds

Service Management - at the Heart of the Cloud Delivering Cloud services requires 2 components: Process Platform Service Processes A Process Platform to manage the virtual

6 Service Management - at the Heart of the Cloud Delivering Cloud services requires 2 components: Process Platform Service Processes A Process Platform to manage the virtual infrastructure Service Processes that deliver the user experience 6 The effectiveness and efficiency of a cloud implementation is predicated on the interaction of these components

7 Additionally, 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 When 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 Software as a service (SaaS) Provides higher levels of service delivery SOA Integration and Enterprise Suites 8 Business process as a service (BPaaS) Customer-written applications or business processes

9 Cloud Deployment Models Public 9 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 Combines Private and Public Service provider uses public cloud resources to create a private cloud

10 IBM 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 10
