  6. 6. Cloud Service Models • Public Cloud • Over the internet • Fast & cheap • Private Cloud • More control • Hybrid Cloud • Interconnected 5
  7. 7. Build Your Own Cloud Use virtualized WebSphere App Server on your hardware IaaS – Amazon BYOS&L - WebSphere App Server PaaS - Bluemix Composable services WebSphere Liberty Profile Pure Application Systems Build reusable & redeployable patterns using the WebSphere App Server PaaS - Cloud Foundry WebSphere Liberty Build Pack IaaS - SoftLayer BYOS&L - WebSphere App Server Public Cloud Economies Time to Market Shared Everything Economics Packaged Services Total Control Maximum Flexibility Maximum Security On-Premises IaaS PaaS WebSphere Application Server - Flexibility in cloud 6
  8. 8. WebSphere Application Server • One solution, multiple deployment options • Right fit your application server • WebSphere Application Server Liberty Core for web applications • Network Deployment for maximum availability, scale, and QOS • Right fit your deployments • Traditional for maximum security, control, flexibility, and SOR • IaaS for hybrid environments and peak workloads • PaaS for Systems of Engagement • Integrated across deployment platforms • Move between platforms with license mobility • Move at your own pace On Premise On Cloud 7
  9. 9. Bluemix was built from the ground up with a user-based and design-centric approach. It addresses these personas and key needs. Our users include novice, born-on-the-cloud, and enterprise developers. Want to compose applications quickly with useful APIs, to avoid tedious backend config. Expect fast time-to-value, simplicity, flexibility, clear documentation. Failing Fast Seconds to Deploy Friction Free Any Language Continuous Integration Mobile Ready Focus on Code Choice of Tools Useful APIs Bluemix Goals: Focus on the Cloud & Enterprise Application Developer 8
  10. 10. Bluemix: IBM’s Cloud Platform • DevOps • Big Data • Mobile • Watson • Business Analytics Bluemix service categories • Database • Web and application • Security • Internet of Things • Integration • Containers Developer experience • Rapidly deploy and scale applications in any language. • Compose applications quickly with useful APIs and services and avoid tedious backend config. • Realize fast time-to-value with simplicity, flexibility and clear documentation. Enterprise capability • Securely integrate with existing on-prem data and systems. • Choose from flexible deployment models. • Manage the full application lifecycle with DevOps. • Develop and deploy on a platform built on a foundation of open technology. Built on a foundation of open technology. Build, run, scale, manage, integrate & secure applications in the cloud 9
  11. 11. Bluemix embraces Cloud Foundry as an open source Platform as a Service and extends it with IBM, third party, and community built services. How does Bluemix work? 10
  12. 12. Key Concepts • cf: the command line tool used to interact with the CloudFoundry environment, via the cloud controller component • Buildpack: a collection of code responsible for transforming pushed application artifacts into a ready-to-run droplet, in a process referred to as ‘staging’ • Droplet: a package containing everything that is needed in order to successfully run your application (e.g. JRE, Liberty, the application itself) short of the operating system • Service: the means of providing runtime dependencies needed by an application, e.g. a database • Warden: the containerization mechanism used to achieve application isolation in the CloudFoundry environment 11
  13. 13. Cloud Foundry Architecture 12
  14. 14. IBM Confidential June 7, 2013 Application Push • Push a stand-alone application to the cloud • cf push –p <path to file> • Default server configuration provided by the buildpack 13
  15. 15. Application Staging Buildpack 14
  16. 16. WebSphere Liberty Buildpack • Buildpack for running applications on IBM WebSphere Application Server Liberty Profile • Designed to run “packaged” servers, web applications and EAR packages • Generates the Liberty server configuration for bound services • Simplifies developers’ lives by requiring minimal configuration and making it easy to consume services • Loads into the server only what is needed for a running application • https://github.com/cloudfoundry/ibm-websphere-liberty- buildpack 15
  17. 17. Service Integration with the Liberty buildpack • IBM services • SQLDB / dashDB • Monitoring and Analytics service • Auto-Scaling • Single Sign On • Data Cache • Session Cache • MQ Light • Cloudant • Third party/community services • New Relic • mysql / ClearDB • Postgresql / ElephantSQL • mongodb / MongoLab Information about bound services is available in the VCAP_SERVICES env var Some services are container managed only (SessionCache) Some services can be either container managed or application managed (SQLDB) Some services contain multiple features which can be separately enabled (Monitoring and Analytics) Some services have local analogs (SQLDB, mongo) and some do not (Monitoring and Analytics) Services may require client driver JARs, extension features (WXS ESA), Liberty features, bootstrap.properties 16

  21. 21. Coding Do’s and Don’ts • Stateless • Ephemeral file system • Ephemeral memory • Ports • Security • Avoid creating new process instances • Avoid writing to the local file system • Capture log information • HTTP session persistence • Listening for inbound connections • Stopping the server • Transport security is terminated at the router • Two-phase commit transactions 20
  22. 22. The Twelve Factor App – http://12factor.net/ 1. One codebase tracked in revision control, many deploys 2. Explicitly declare and isolate dependencies 3. Store config in the environment 4. Treat backing services as attached resources 5. Strictly separate build and run stages 6. Execute the app as one or more stateless processes 7. Export services via port binding 8. Scale out via the process model 9. Maximize robustness with fast startup and graceful shutdown 10. Keep development, staging, and production as similar as possible 11. Treat logs as event streams 12. Run admin/management tasks as one-off processes 21
  23. 23. DayTrader • Performance benchmark app • Java EE 6 • Uses database for persistence • The application or database does not scale • “System of Record” • Nothing cloud about it! 22
  24. 24. Deploy DayTrader to Bluemix • Tooling to help migrate • IBM WebSphere Application Server Migration Toolkit V8.5.5 – Liberty Technology Preview • Talks to either a cloud or on-premise database • Value-Add • Application can scale horizontally • Load balancing • High availability 23
  25. 25. Database • Use database services provided by Bluemix • Powerful auto-configuration features makes it easy to consume! @Resource (name = "jdbc/mydb") private DataSource db; “mydb” is the name of the service instance created in Bluemix 24
  26. 26. Scaling of the runtime • Scale up and down in seconds! • Condition based scaling 25
  27. 27. Session Persistence and Caching • WebSphere eXtreme Scale • Distributed object caching • Session off-load and replication 26
  28. 28. Other Application Services 27
  29. 29. Adoption of other services – Make it Engaging! • Rules Engine • Use Business Rules to monitor stocks, portfolio and perform actions when criteria is met • Social • View friends portfolio • Post tweets and collaborate on stock transactions • Stay connected w/ tweets related to your portfolio • Push/SMS • Instant notifications to buy or sell • Cloud Integration • Export backend interfaces as a service • Single Sign-On • Improve authentication • Watson • Add real intelligence to your application! 28
