  4. 4. Going to the CloudKeys to achieving the Cloud. From Virtualization to Orchestration. Getting to the cloud is as much a mystery as what to do once there. We will discuss the types of clouds, the 4 steps to get there and what we can do now to prepare your enterprise for the leap.4
  5. 5. Agenda Before We Begin Cloud Overview Steps to get to the Cloud Lessons Learned5
  6. 6. Cloud Definition Definition • Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is comprised of five key characteristics, three delivery models, and four deployment models. Key Characteristics • On-demand self-service - SaaS - Public • Ubiquitous network access - PaaS - Community • Resource pooling - IaaS - Private • Location independence - Hybrid • Homogeneity • Rapid elasticity • Measured service Source: Peter Mell & Tim Grance – National Institute of Standards and Technology – Information Technology Lab6
  7. 7. XaaS, the concepts included in theCloud • EaaS, Everything as a Service, the transformation of IT from a physical, well established environment into a capability that is available at people’s fingertips without knowledge of where the assets are. • SaaS, Software as a Service, an environment where users can run predefined applications directly from their web browser. • PaaS, Platform as a Service, an environment in which the user is provided with a rich environment in which he can run his applications as long as they are programmed in one of the languages supported by the platform (Java, Python or .Net) • IaaS, Infrastructure as a Service, an environment that provides the user with processing power, networking, storage and the other necessary resources allowing him to run his software and applications7
  8. 8. 4 Cloud Deployment Models Private Cloud • Enterprise owned or leased Community Cloud • shared infrastructure for specific community Public Cloud • Sold to the public, mega-scale infrastructure Hybrid Cloud • composition of two or more clouds Source: Peter Mell & Tim Grance – National Institute of Standards and Technology – Information Technology Lab8

IT is undergoing disruptive change IT wants Google/Amazon like agility and efficiency as Business needs technology an on-premise or hosted to enable innovation quickly private cloud Services increasingly and now has more options span many physical, beyond its own IT org… virtual and external … as “services”, not resources technology, with clear Aspirations for understanding of capabilities and cost private cloud Composite Service IT is expanding its role to include supply chain manager Physical Virtual IaaS PaaS SaaS Traditional MSP1 0

  14. 14. 4 Key Steps Consolidate • Consolidate Applications and Services through Virtualization • Leverage Composite Services instead of individual services Optimize • Pair Virtualization with management • Integrate Lifecycle Management disciplines • Integrate Management across domains and spaces Automate • Provisioning of services through Templates • Reservations are created on demand • Automation always scales; people do not Orchestrate • Dynamically instantiate and decommission VMs based on user load • Monitoring captures and fires alerts; Monitor the entire system not just parts • Capacity for configuring, managing and reporting Virtualization + Automation + Service Management = Cloud1 4

  17. 17. • Before We Begin Cloud Overview• Steps to get to the Cloud Lessons Learned 1 7
  18. 18. • Lessons Learned • Monitor the entire system; not just parts • Only use standards; stay away from Proprietary systems • Reengineer the architecture around Virtualization instead of dropping it in and then expecting 100% of the benefits • Lower costs by removing hardware and the related support costs − Multitenency is the best way to drive down cost and attain ROI• 1 8 3/04/11 0
  19. 19. • Lessons Learned • Make your services consumable : − Prioritize based on business requirements − Consumerize by providing you catalog; must cover all businesses not just your cloud services • Maintain Security – Define your requirements before looking for vendors − data at rest/encryption• − Country where data will reside, local laws − Monitoring/ 3rd Party Auditing and certifications • Cloud is as much about process and policy as it is about technology 1 9 3/04/11 0
  20. 20. • Lessons Learned • Organizations struggle to maintain low to no value applications; perform Application Rationalization and define your Service Catalog • You cannot control things you do not know about; Catalog your offerings • Ensure you can point to every server in the Datacenter and you know:• − What is running on it − Who is responsible − What happens when it fails 2 003/04/11
  21. 21. • Lessons Learned • There is no big bang approach to get to the cloud; start small and grow • Metrics will need to be tested, refined, implemented, refined further and re-implemented long after the implementation phase closes • A knowledgeable partner can reduce time loss due to forgotten steps (like implementing technology only to be• forbidden by policy) 2 103/04/11
