Traditionally business process services are built on applications that are running within the enterprise to fulfill business demands. In the recent past, the concept of SaaS Clouds gained significance with services being hosted in a common cloud environment within the enterprise or outside the enterprise. In this article, we propose an innovative implementation of Cloud-based SaaS Enterprise Frameworks in "Corporate Action Events" Processing. A lot of discussions have appeared on how enterprise architecture services and cloud-based services, namely SaaS, are connected within an organization and how these architectural styles are better leveraged to fulfill business domain demands. [1] Enterprise architecture often describes the blueprint of applications and strategies within an enterprise, whereas enterprise SOA is more about enterprise services and provides integr... (more)

In the recent past, the concept of services in a cloud environment gained significance with services being hosted in a common cloud environment within the enterprise or outside the enterprise. In this article, I described the various steps involved in moving services from an enterprise level to cloud-based environment as part of a cloud implementation. Traditionally an organization's Enterprise Services Architectures are considered in terms of Business Architect... (more)

Cloud-Based Reference Architecture

During the past few years enterprise services have been leveraging cloud-based technologies for several reasons including scalability and automated provisioning capabilities [1, 2]. In a development / design environment, cloud platforms provide dynamic and repeatable processes for creating environments that help reduce lead times and provide cost-effective optimizing infrastructure apart from eliminating manual intervention and minimizing rework due to environment defects. In a deployment environment, the cloud leverages virtualization, distributed applications and grid-based a... (more)

Enterprise Data Platform Reference Architecture

Social media applications like Facebook walls, Linked-in dashboards and Twitter tweet-boards have inadvertently opened up a new paradigm of pushing data/information to the users. Enterprise IT applications, on the contrary, expect users to navigate to the information using designated UI forms or user reports; obviously the social media type of paradigm of pushing relevant/important data can significantly improve the productivity and efficacy of users. Typically in a Manufacturing Supply Chain enterprise, operations span activities across complex manufacturing automation and suppl... (more)

Migrating from WebLogic 6.1 to 8.1

BEA's name is synonymous with the application server. Most applications running on Unix in North America run on BEA's WebLogic server, particularly financial apps. The current stable WebLogic 8.1 version does a lot more than earlier versions. Migrating to new versions is always challenging and risky, but is done for efficiency and new capabilities, and to stay current with a vendor's products and support. Most applications developed on the WebLogic 6.1 used JDK 1.3 or earlier. A move from WebLogic 6.1 to 8.1 means making our applications compatible with JDK 1.4.1 or higher since... (more)
