  3. Introductions Developer Relations Group sdk-support@rackspace.com Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  4. Goals jclouds Create a cloud server SSH Apache HTTP Server Cleanup Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  5. //TODO: This workshop code will use either: Devstack (local OpenStack deployment on the HOL VM) Rackspace (more features will be demonstrated) This will require sign-up. Start here: https://cart.rackspace.com/cloud/ Free developer tier available Workshop VM - HOL6628 (this VM) http://tinyurl.com/obql73s Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  6. Buzzword Networked and distributed computing Variety of services Compute (servers) Storage (files) Databases Email … The Cloud Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  7. The Cloud Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  8. The Cloud Cloud VM VM Your System AP I VM SDK This can be an application server Or your home machine Or belong to one of your end users Or a cloud VM Or a smartphone Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  9. Advantages Metered pricing (pay as you go) Project scalability (unlimited) Safer (offsite/redundant) Economies of scale Expertise Support The Cloud Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  10. Disadvantages Less hardware control Provider-controlled downtime Virtualization (efficiency) Provider lock-in Provider-specific apis/sdks/features Expensive to switch clouds or deploy locally jclouds minimizes this disadvantage The Cloud Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  11. Cloud OS Open-sourced by Rackspace and NASA (2010) Free Supported AT&T, HP, IBM, Red Hat, Rackspace, Dell, Cisco, Intel, Vmware, … OpenStack Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  12. Cloud SDK Java (and Clojure) Easy Portable and cloud-agnostic Dozens of contributors Open source jclouds Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  13. HTTP calls Authentication and re-authentication Pagination Polling Rate limits Retries Abstractions Logging Less code jclouds Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  14. Services Storage Compute VM Images Load Balancers DNS Databases … Providers Openstack Rackspace HP Amazon Azure … jclouds Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  15. jclouds Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  16. We will: Use devstack Local deployment of OpenStack Used for testing No providers needed, everything is local Default image good for testing, fast, lacks features Solutions! Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  17. Alternatively: Use Rackspace Openstack-compatible Fast, easy, and it works! Credit card needed, free tier available Many images supported https://cart.rackspace.com/cloud/ Solutions! Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
  18. Also: Use jclouds in cloud-agnostic way Showcase compute code Best practices Gotchas and workarounds Solutions! Solve the Cross-Cloud Conundrum with jclouds http://j.mp/16nH6a0
