Transcript

  • 1. Apache JClouds Cloud interfaces, simplified Hiranya Jayathilaka Dept. of Computer Science, UCSB S
  • 2. Roadmap S  Cloud computing S  Challenges S  Apache JClouds S  Demo S  Pros and cons S  Summary and conclusion
  • 3. The Cloud Revolution S  Cloud computing is revolutionizing the way software is developed and delivered. S  Software-as-a-Service (SaaS) S  Platform-as-a-Service (PaaS) S  Infrastructure-as-a-Service (IaaS)
  • 4. Many Benefits S  Cost effective S  Reduced maintenance overhead S  Easy and fast provisioning – Improved time-to-market S  Autoscaling and elasticity S  Fault tolerance
  • 5. The Other Side of the Coin
  • 6. Challenges S  How do you select the cloud provider that’s right for you? S  How do you port your application from one cloud provider to another? S  How to develop multi-cloud applications?
  • 7. Enter, JClouds S  An open source library that facilitates developing applications for a wide range of cloud providers. S  Implement your application using JClouds, and run it on your favorite cloud without any code changes. S  Simple, intuitive APIs. S  Java and Clojure support.
  • 8. History S  Started in March 2009 by Adrian Cole as an open source project. S  Initially based in London, developed mostly by European Java community. S  Contributed to Apache in April 2013. S  http://wiki.apache.org/incubator/jcloudsProposal S  Already popular in the industry – Used by the likes of Adobe, CloudBees, RedHat, Twitter and SalesForce. S  http://jclouds.incubator.apache.org/documentation/reference/ apps-that-use-jclouds/
  • 9. Getting Started S  No binary download J S  The documentation provides the necessary configurations for popular project management tools, so JClouds can be included in your project as a dependency. S  Maven S  ANT S  Leiningen
  • 10. JClouds APIs S  Compute Service API S  For managing compute nodes (VMs) in the cloud S  Blobstore API S  For storing data in the cloud
  • 11. Compute Service API S  Key abstractions S  Hardware S  Operating system S  Template S  Supported providers S  AWS (EC2), Bluelock, CloudSigma, ElasticHosts, Go2Cloud, GoGrid, Green House Data, HP, Ninefold, OpenHosting, Rackspace, ServerLove, SkaliCloud, SoftLayer, Stratogen, TRMK, TryStack
  • 12. Starting a VM from an Image
  • 13. If You Don’t Have an Image?
  • 14. More Control Over Templates
  • 15. Access VM Metadata
  • 16. SSH to Remote VM
  • 17. Dealing with Package Managers
  • 18. Managing Clusters
  • 19. Blobstore API S  Key abstractions S  Container S  Folder S  Blob S  Supported providers S  AWS (S3), CloudOne, HP, Azure, Ninefold, Rackspace, Synaptic
  • 20. Downloading a Blob
  • 21. Write Blob
  • 22. Upload File
  • 23. Access Blob Metadata
  • 24. Logging Support
  • 25. Demonstration S  Scenario S  Start an Ubuntu VM in EC2 S  Upload a Python script and a Java application to the VM (Java application also based on JClouds) S  Install Python and JRE on the VM using apt-get S  Run the Java application on the VM to download a data file from S3 S  Run the Python script on the data file S  Upload the output to S3
  • 26. Pros S  Powerful abstractions: Simple + High-level + Convention over configuration S  Location awareness baked into the API S  Easily manage clusters of nodes S  Excellent portability S  Unit testable S  Free and open source (ASL 2.0) S  “It just works” (YMMV)
  • 27. Cons S  Still in the Apache Incubator S  Limited documentation S  Potential “Jar hell”
  • 28. Summary S  Cloud computing brings a horde of benefits – But the diversity can be overwhelming. S  Several challenges with respect to evaluating cloud vendors and porting application across cloud platforms. S  Apache JClouds provides a simple and feature-rich approach for developing cloud applications that are easily portable across multiple vendors.
