IBM Software Group | Tivoli software Agenda  What is Cloud Computing  Evolution  Public v/s Private Cloud  Get Technical - Architecture  Service Management - TSAM  Available Clouds  Pro and Cons  Q & A

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 : * 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

IBM Software Group | Tivoli software User Request Interface and IT Operational Views  Enable end users to request services Enable end users and IT staff to monitor status of requests Enable IT operations staff to manage the delivery of the services View monitoring statistics of cloud deployments, including breached thresholds Orchestration of People, Processes, Data, Technology  Enable the fulfillment of user requests based on best practices for request types & conformance to organizational processes Consistently enforce operational policies for service delivery Provide usage and accounting management for cloud services Provide security for cloud services Enable green initiatives through optimized utilization of resources Automate Requests and Operational Tasks to Improve Efficiency and Effectiveness  Automate the orchestration of technology to fulfill user requests for cloud services Automate processes and repetitive IT administration tasks for optimized utilization of resources Provide the ability to automatically meet higher scalability demands Provide process automation capabilities, enabling the value of change, release, and configuration management disciplines in a cloud computing environment Automation Control Visibility Cloud Computing requires Service Management “Virtualization without good management is more dangerous than not using virtualization in the first place,” –Gartner

IBM Software Group | Tivoli software Adds CPUs Simple Deployment Scenario: Test Center Cloud – with simple operational management task Tivoli Service Automation Manager  Selects resource from pool  Executes Management Plans to install image John, Test Center Manager Requests Capacity for a specific test through a self- service GUI Specifies Parameters:  Project Name, Owner  #CPUs, Mem, Storage  Type of VM (LPAR or VMWare)  Image containing SW stack John, Test Center Manager Receives ready to use Test System Gives testers access VMWare Linu SW Stack Anne, Bob, Linda, Testers Use Test System to run tests Two more testers are assigned to project Add‘l tests required, more capacity needed John, Test Center Manager Requests more CPU Linux SW Stack Tivoli Service Automation Manager  Selects resources from pool  Executes Management Plans to add CPUs Specifies Parameters:  Project Name, Owner  # add‘l CPUs, Pass Parameters System Ready Deploys System Run Tests Grant Access Run add’l Tests Pass Parameters Marion, Data Center Admin Approves request Pass Parameters

IBM Software Group | Tivoli software Cloud Market Place

IBM Software Group | Tivoli software Disadvantages of cloud computing Dependent on internet connections Users are subject to terms and conditions Data in hands of a 3 rd party It’s not environmentally sustainable No worldwide accepted standards
