VistaEdge Technologies Web-Services

Technologies : Services Offered in the area of Web-Services

Web Services Assessment & Strategy : VistaEdge provides consulting services to organizations to help formulate a strategy that leverages the Web Services architecture based on a well-defined ROI. As part of these services, clients are offered a Web Services Pilot (WSP); WSP demonstrates business value & ease of implementation so that an enterprise can take well-informed decisions.
Application Transformation : VistaEdge offers services to transform existing applications such as ERP, CRM, SCM, Document Management, Knowledge Management and legacy systems into application web services. This is the first step towards achieving complete Internal Business Process Integration (IBPI) & External Business Process Integration (EBPI), leveraging the Web Services architecture.
IBPI & EBPI : VistaEdge has a complete end-to-end framework to implement IBPI and EBPI based on the Web Services architecture. Our framework is also capable of leveraging investments made in EAI.
Product Transformation : VistaEdge offers services that transform software products to support web services. We achieve this by leveraging our understanding of product architecture and expertise across multiple Web Services technologies and platforms.
Performance & Tuning : Perhaps the biggest challenge with evolving and emerging technologies is to ensure consistent and superior performance. The abstraction layer brought in by Web Services demands additional processing and expertise. This often results in an inconsistent performance. VistaEdge has extensive experience with various Web Services platforms and architectures, in both lab and production environments. This helps us deliver superior performance and tuning services to our clients.

Key Benefits

Application Maintenance: Message broker based IBPI or EBPI leads to tight point-to-point integration - unlike in Web Services where integration is loosely coupled and changes in one application do not result in cascading changes across others. Hence the maintenance becomes simple, reducing the overall effort and cost.
Interoperability : Over the years enterprises have invested in various systems and applications, built using multiple programming languages and component architectures. In addition, a majority of enterprises have grown through mergers and acquisitions, which bring in completely different systems & processes. Web Services are based on open standards specially built to abstract the communication between any system or application, irrespective of the underlying language or architecture used.
Ease of Personalization & Customization : The ability to deliver personalized service and customized application tools is key to achieving a high level of productivity and satisfaction across different enterprise stakeholders. Web services' dynamic binding feature along with additional XML based parameterization of application & interfaces, facilitates mass personalization and customization.
