Application Grid

The new version 10.3.2 release of WebLogic Server 11g Release 1 includes a Technical Preview of WebLogic SCA. In WebLogic SCA, you can write Java applications using Plain Old Java Objects (POJOs) and expose components as SCA references and services, using SCA semantics configured in a Spring application context.

WebLogic SCA applications run seamlessly in WebLogic Server (via the WebLogic SCA Runtime) and can be used as components in Oracle SOA composites.

Oracle Fusion Middleware SVP Hasan Rizvi discusses Oracle Tuxedo as a modern application server for C/C++/Cobol applications. With its industrial strength and extreme high performance, it is typically used for mission-critical applications and is able to support sub-second response times, hundreds of thousands of distributed transactions per second, and provides five nines availability and reliability. Hasan emphasizes the fact that Tuxedo is a strategic offering within Oracle's application grid portfolio. It's the market-leading platform for re-hosting mainframe applications. With an extremely loyal customer base and very high focus and investment within Oracle, Hasan suggests that Tuxedo is poised to improve further -- in its capabilities and market leadership.

In a recent interview with Cloud Computing Journal, senior vice president of development for Oracle Enterprise Manager Richard Sarwal highlights Oracle’s fundamental objectives of making cloud computing enterprise grade and supporting both public and private cloud. Richard describes the role of middleware in cloud computing, detailing how application grid’s automation and dynamic capacity adjustment are primary enablers of cloud architectures. See Richard’s keynote at the Cloud Computing Expo tomorrow!

Richard Sarwal, SVP Product Development for Oracle Enterprise Manager is interviewed by Jeremy Geelan of Sys-Con Media's Cloud Computing Journal and talks Application Grid right at the get go.

"Richard Sarwal: Oracle pioneered Grid Computing more than five years ago with RAC, ASM and Enterprise Manager Grid Control. We continue to enhance and refine those products, and they are still differentiated in the market today. Over the last few years, we've greatly expanded our grid offerings with Application Grid in the middleware layer (WebLogic, Coherence, Tuxedo and JRockit), Oracle VM for server virtualization, and Exadata smart storage server. So today, we've got the full stack of grid products from storage and infrastructure up through databases and middleware, all managed in an integrated fashion by Oracle Enterprise Manager.

Grid Computing combines server virtualization and clustering across the stack to provide the dynamic, shared infrastructure that forms the basis of Cloud Computing. Cloud Computing shares many of the characteristics and technology requirements Grid Computing. Oracle's emphasis on Grid Computing capabilities such as dynamic resource provisioning, dynamic resource scheduling and highly automated management of clusters and virtual machines map directly to the requirements of Cloud Computing. Oracle's highly automated management of server clustering (RAC and WebLogic) and server virtualization provides the elastic scalability and fault tolerance required for enterprise class clouds. Policy-based automation enables management of virtualized resources, and metering resource consumption enables pay-per-use billing and chargeback. So our Grid Computing products provide the key building blocks for Cloud Computing."

Back at BEAWorld in 2006, BEA introduced the concept of “microServices Architecture”, which involved modularizing the internals of WebLogic Server and taking advantage of the OSGi standard. The WebLogic Server team has continued to make great progress in modularization ever since then, bringing significant benefit to installation, startup, and component updates. In short, by installing only what you need, you minimize resource footprint and startup time while enabling incremental updates that are fast and reliable. This is important for any use of an application server, but it is particularly beneficial in an application grid environment because it means that the grid’s dynamic adjustment of an application’s capacity can happen in even more finely-grained increments (if your app doesn’t use JMS, your grid is not wasting the cycles and footprint of installing and starting it when adding a node to a cluster, for example). Gavin Clarke over at The Register has some comments in a write-up on this based on a recent OpenWorld session.
