Private cloud-webinar

  1. 1. Setting up an in-house Private Cloud Chintana Wilamuna
  2. 2. Cloud Computing• Buy computing power, storage or services on demand• Service Delivery Model • What is given “as a Service” • Pay per use • Self service provisioning • Virtually unlimited resources • Resource sharing• Cloud Deployment Model • Where is the cloud deployed
  3. 3. Cloud Computing – Service Delivery ModelFor end-usersFor developers, integrators, architectsFor infrastructure specialists
  4. 4. Cloud Computing – Deployment Model● Public – IaaS, PaaS, SaaS available on the Internet – Use one of the cloud service providers – Information stored and managed by provider - SLA● Private – Have a cloud, in-house – IaaS provides by hardware on your data centers – PaaS running on your IaaS – SaaS executing on your PaaS● Hybrid● Community
  5. 5. Hybrid cloud● Combination of private + public cloud● Private cloud for core services● Public cloud for burst capacity – Short term
  6. 6. Bridging private & public clouds1. Use WSO2 Cloud Services Gateway (CSG)2. Use Amazon Virtual Private Cloud (VPC)
  7. 7. WSO2 Cloud Services Gateway
  8. 8. Amazon Virtual Private Cloud
  9. 9. SOA & cloud computing
  10. 10. Enterprise IT in 2010
  11. 11. Enterprise IT in 2015+
  12. 12. Why public cloud?● No need to buy machines● No need to setup● No need to spend anything, if we are not using● No need to wait, if you need more computing power● It is just out there, ready to be used
  13. 13. Why not public cloud?● Data is wealth, key to competitive advantage – Not supposed to move it out of premises● Security reasons – Take no chance on sensitive elements in IT● Mainframe -> cloud – Legacy apps are better off the way they are● Quality of service - Availability, SLA● Regulations – Government and industry regulations
  14. 14. Prerequisites for private cloud● Hardware – CPUs supporting virtualization – Large storage – High speed network● Cloud ready OS – Ubuntu Server LTS● Cloud infrastructure – Eucalyptus
  15. 15. Private cloud - IaaS
  16. 16. Private cloud - UEC● EC2 compatible API – Stratos Autoscaling code on EC2● Open source & wide availability● Ubuntu LTS – Support for 5 years
  17. 17. UEC configuration tips● Choose the right topology – # physical systems – Where CLC/Walrus/CC/NC is installed –● Network configuration –● Monitor instance memory usage
  18. 18. Beyond private IaaS● Define your purpose – Why do I want a private IaaS? – How to utilize it – Possible usage patterns● Too low level? – Deal with machines/instances – A minimal OS● IaaS = cloud?!
  19. 19. A complete platform● PaaS – Running on top of your IaaS – More high-level – Easier to develop● Concentrate on your apps● A cloud native PaaS – Take advantage of “cloud features”
  20. 20. Cloud native• Supports deployment into a Cloud: – Dynamic and Just-in-Time Discovery and Wiring• Able to work with the underlying cloud infrastructure – Elasticity• Provisioned as a Service – Multi-tenant, Portal and Web Service-based provisioning• Managed as a Service – Billed and Metered, Flexibly Monitored• Incrementally Deployed and Tested – Supports continuous update, side-by-side operation, in- place testing and incremental production
  21. 21. Cloud native middleware
  22. 22. Summary• Cloud computing• Public / Private / Hybrid / Community clouds• Bridging public – private clouds• Future of enterprise IT• Public cloud pros/cons, why private cloud• Private cloud – UEC• Beyond private cloud• PaaS on top of IaaS - Stratos
