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)

Reference Architecture for Securing Web Services in a Heterogeneous Environment

Web Services have played a key role in integrating heterogeneous applications, particularly in cross domains. As part of identity management, Security Token Services are used for request and response tokens. However, we need multiple communication channels among Security Token Services when multiple applications in different domains try to reach other Web Services. In this article we have proposed a Master Security Token Service (MSTS) that can act as a broker for all security authorization without duplicating the effort at every domain. In a world of heterogeneous systems where ... (more)

Traditionally an organization's Enterprise Services Architectures are considered in terms of Business Architect... (more)

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)
