Services Architecture

A layered topology for Web Services!
Web Services are transforming the way that all applications are being developed. Some organizations are using them to extend the life of legacy data, while others are providing applications over the Internet. We utilizing a service access layered approach towards service delivery will help your organization better provision resources when deploying Web Services.



Client Services Access Layer (C.S.A.L.) The array of devices that consumers request information and services from requires businesses to provide multi-channel connectivity policies. Today, sellers of products and services are providing low cost integration technologies, like Web Services, that reduce the cost of collaboration. eSigma provides a standardized means of Web Service connectivity. Business Services Access Layer (B.S.A.L.) eSigma delivers a standardized catalog of functional business services, application- or machine-based, to systems for execution and consumption. The B.S.A.L. promotes core business processes and allows organizations to share them directly with external organizations. The advancement of XML, and Web Services, provide an effective means of process collaboration that reaches beyond the transactional model. Web Services are able to extend functional legacy systems so that they can be leveraged across multiple internet-based devices.	Information Services Access Layer (I.S.A.L.) The I.S.A.L. provides data access and transformation technologies to organizations so they can execute business-to-business processes. Many Web Services, and related taxonomies, being developed are designed to facilitate access to information that resides in databases and legacy applications. Network Services Access Layer (N.S.A.L.) Running business and information services over public networks require different layers of network technology working together to deliver secure process collaboratio. The advancement of XML protocols, such as SOAP, require organizations to incorporate them into their IT network infrastructure. The N.S.A.L. optimizes the different layers of the OSI reference model, creating layers of abstraction enabling Web Services to be securely brokered over the Internet.
