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 architecture patterns. In this article, I discuss creating a reference architecture and designing financial supply chain applications so they can be enabled for cloud environments [3]. Some of the challenges faced by the financial supply chain applications include lots of integrations, innova... (more)

Developing a CICS-Based Web Service

Web services have opened opportunities to integrate the applications at an enterprise level irrespective of the technology they have been implemented in. IBM's CICS transaction server for z/OS v3.1 can support web services. It can help expose existing applications as web services or develop new functionality to invoke web services.

Service Enablement of Enterprise Data through Mobile Devices

It's well known that in recent times that consumption of data or a service through mobile applications is increasing exponentially due to the increase in the mobile customer base and the increase in the number of mobile devices connected to various systems disproportionately(1). That means in most of the cases, consumers of mobile devices are increasing more than traditional desktop browser based service model of consumption. These end users use a large number of different types of devices starting from standalone desktops, laptops, and tablets to mobile devices. It is expected t... (more)

Performance Improvement in a J2EE Application

Java is hot. Just nine years old, it has become one of the leading development environments in the world. Millions of programmers and thousands of companies use it, and half of all IT managers expect to deploy J2EE applications this year. But Java's popularity hasn't necessarily made it easy for the growing population of Java code jockeys. Ever-shortening production cycles have kept the heat on programmers, who increasingly work in large teams to meet production milestones. And every day those teams come face-to-face with an immutable law of software development: the more code y... (more)
