IBM Software Group | Tivoli software Cloud Computing (???) Cloud represents the internet. It is a a data center in the sky. Virtual servers available over the internet Save in-house investments in hardware and software applications. A platform for a new breed of enterprise apps A way to bring Web-scale computing to small and large businesses. Subscription-based or pay-per-use service. Buzz….ers ! Software as a Service (SaaS) Hardware as a Service (HaaS) Platform as a Service (PaaS) Utility computing Web Services in the cloud Examples : * Email services – gmail, yahooMail ; * Online video, TV, news * Services - Google Apps, Photo sharing - Flickr

IBM Software Group | Tivoli software Evolution of Cloud Computing Solving large problems with parallel computing Network-based subscriptions to applications Offering computing resources as a metered service Anytime, anywhere access to virtualized IT resources delivered dynamically as a service. Software as a Service Utility Computing Cloud Computing Grid Computing Abstraction –> Simplification -> Capability Aggregation

IBM Software Group | Tivoli software Public Clouds Resources - applications and storage, available to the general public over the Internet. May be free or offered on a pay- per-usage model. Benefits Easy and inexpensive set-up hardware, application and bandwidth costs are covered by the provider. Scalability to meet needs. No wasted resources because you pay for what you use Examples 3Tera, Eucalyptus, Cloudera Private Clouds Internal cloud or a corporate cloud - A proprietary hosting. Services to a limited number of people behind a firewall. Allow corporate network and datacenter administrators to effectively become service providers that meet the needs of their "customers" within the corporation. An organization that needs or wants more control over their data than they can get by using a third-party hosted service such as Amazon's Elastic Compute Cloud (EC2) or Simple Storage Service (S3). Examples IBM, VMware, Sun/Oracle
