+ RightScale = Making Hybrid Cloud a Reality


Published on

Kevin Kluge, VP Engineering at, led this session at the RightScale User Conference 2010 in Santa Clara.

Session Abstract: Hybrid clouds offer the best of both worlds – the complete control of a private cloud coupled with the ability to handle elastic workloads by bursting into public clouds like Amazon EC2. In this talk, we describe how to build a hybrid cloud using plus RightScale. This hybrid cloud solution consists of an on-premise private cloud implemented using CloudStack and workload bursting to Amazon EC2 implemented using RightScale.

No notes for slide + RightScale = Making Hybrid Cloud a Reality

  1. 1. Making Hybrid Cloud a RealityKevin VP Engineering<br />
  2. 2. Agenda<br />2<br />Establish terms<br />A RightScale / hybrid cloud solution<br />Deployment architecture<br />Demonstration<br />Future directions<br />
  3. 3. What is a Hybrid Cloud?<br />3<br />Two or more clouds<br />Some servers on a private cloud<br />Some servers on a public cloud<br />Optionally used for bursting<br />Single management interface<br />Spans both public and private clouds<br />Enables consistent view of servers across clouds<br />
  4. 4. Hybrid Cloud Prequisites<br />4<br />No need to move large datasets to burst<br />Simple websites, content systems<br />OR<br />Large pipe between public and private<br />So big data location doesn’t matter<br />WAN optimization<br />
  5. 5. Who is<br />5<br />IaaS software provider<br />Orchestration layer<br />Open Source<br />Enables secure, multi-tenant, scalable public and private clouds<br />GA software since 2009<br />CloudStack product is RightScale ready<br />
  6. 6. A RightScale / Solution<br />6<br />Private cloud running CloudStack<br />Physical resource management through CloudStack<br />Highly Scalable<br />Server (Guest) management through RightScale<br />Public cloud <br />Any RightScale-managed cloud is sufficient<br />EC2 in this example<br />RightScale manages images, server arrays, and autoscaling across clouds<br />Provides single management interface<br />

  8. 8. Demonstration Deployment<br />8<br />Private Cloud on CloudStack<br />Virtual load balancer (HAProxy)<br />Two HTTP-based app servers<br />Public Cloud on EC2<br />Autoscaling array of app servers<br />Load generating client<br />Result: as load changes on application servers the public cloud array grows/shrinks in size<br />
  9. 9. Demonstration Deployment<br />RESIZE<br />RIGHTSCALE<br />AppServer 3<br />…<br />VOTE<br />Public Cloud EC2<br />AppServer N<br />Private Cloud CloudStack<br />AppServer 1<br />Load <br />Balancer<br />VOTE<br />AppServer 2<br />
  10. 10. Demonstration Implementation<br />10<br />Public cloud array of app servers<br />Cloudburst tag<br />Min of 0, max of 10<br />Same function as private cloud app servers<br />Application Servers<br />Register with load balancer on create<br />Regardless of server location<br />Vote on array sizing based on CPU utilization<br />Find array with “cloudburst” tag<br />Grow at >60% busy, shrink at <30% busy<br />Unregister from load balancer on destroy<br />

  12. 12. Future Direction<br />12<br />Deploying a private cloud is challenging<br />Deployment architecture, fault tolerance<br />Network configuration<br />Storage selection<br />Hypervisor selection<br />Scalability plan<br />Security review<br />Therefore hybrid clouds are challenging<br />A SaaS solution can help!<br />
  13. 13. The Cloud Kit for Private or Hybrid<br />13<br /><ul><li>Private cloud with external management</li></ul>Compute servers (hypervisors) run on customer premises<br />Configure compute servers with credentials for SaaS account<br />Cloud Kit agent connects to SaaSCloudStack Management Server<br />All user actions through RightScale<br />Users never see a CloudStack UI<br />RightScale enables hybrid cloud<br />
  14. 14. The Cloud Kit<br />14<br />Optional public cloud of your choice<br />Fewer choices  easier deployment<br />Prescriptive about technology choices<br />No administrator UI?<br />Still scalable<br />Simplicity helps scale<br />

  16. 16. Summary<br />16<br />Hybrid clouds are here today<br />RightScale + <br />Consistent experience across EC2 and private cloud<br />Bursting across cloud boundaries<br />Private and hybrid clouds can be easy<br />SaaS can help<br />CloudStack + Service 2011<br />Thanks!<br />
