This presentation discusses the concept of the Cloud, Platform as a Service, the Application Server and the Application. It then moves on to explain what WebLogic has to offer to provide the platform in the cloud to implement the PaaS. It mentions a few of the most important features in WLS that help to power the cloud.

  • JDBC Data SourcesEJB/JPAJMSLogging, monitoringPolicies (OWSM)WorkmanagerTimersjmx,/mbeansCache
  • Cache – spreekuit: kasjeKastjesBrowser: Client (browser, cookie or Java Script memory; HTML 5 offers persistent, cross session local db like storage)App Server : Edge (WebServer)JVM (and cluster)Cross cluster shared cachedb or memory gridDatabase (not requery at least)
  • Self explanatory. Oracle Coherence creates a single, large virtual memory space enabling applications to scale linearly while also improving performance and reliability. Caching data in memory improves application performance by bringing the data closer to where it is needed. It further improves performance since data is duplicated at least once and hence data can be acted upon in parallel. Data Availability is vastly improved.
  • The native integration of Coherence with WebLogic Server results in the following capabilities:Coherence provides out of the box integration with WebLogic Server. This means that Coherence*Web is a deployment option on the WebLogic Server platform that enables a tighter integration with WebLogic Server for Http Session management. Coherence*Web benefits applications that manage large HTTP Session State objects, when running into memory constraints due to storing HTTP Session object data, and/or have existing Coherence Cluster and would like to offload HTTP Session storage to a Coherence Cluster. With the Coherence and WebLogic Server integration customers benefit from:Improved fault-tolerance for the web-tier from ability to manage large http session state objects. Whereas WebLogic Server is able to provide session state persistence within the application server, Coherence*Web is able to extend it across application domains and application servers. Session state is now stored in Coherence cache(s) which can span multiple applications, multiple domains and heterogeneous application server environments (e.g. WebLogic Server and iAS).Improved performance for the web application from having the ability to load more user/application specific session data in-memory without having to worry about failure or data loss. With this capability more data is stored closer to the application, which results from improved performance (over having to fetch data from the backend systems). Improved deployment productivity from integration of WebLogic Server 10.3 and Coherence 3.4.2 out of the box. Customers who now want to use WebLogic Server and Coherence*Web together, do not need to instrument their web applications.

    • 4. Castle in the clouds
    • 5. Jan Snel – Flexible Building
      No up-front investment
      Scale Up – quickly expand into new units
      Scale Down – have units removed when no longer required
      Offices can quickly be relocated to a different site
      Building maintenance is taken care of
      Day to day monitoring and security surveillance
      Standardize on office layout and interior
      Additional office units are available in case of emergencies (fire, flooding, …)
    • 6. Incorporation
    • 7. Or no Incorporation
    • 8. Three brothers…
    • 9. The Three SNEL brothers
    • 10. The Snel Brothers
      Piet Snel – provides the plot on which to build (including electricity, water, sewerage,…)
      So you can build your own units if you want to
      Jan Snel – provides turn-key office space from flexible building units and office furniture
      On his brother’s plot or on your own plot
      Simon Sneller – provides the services that your staff would have provided from the new office
      You do not have to hire & train (& fire) people
      Perhaps they sit in Jan’s building, possibly on Piet’s plot. Or in some unknown location somewhere.
      You do not have to care!
