Layered Solutions Architecture

A look into the System Layers that enable SOA
The goal of any organization is to develop an intelligent systems architecture that maximizes the organizations current business processes, making them accessible to an array of consumers and devices in or outside the firewall. It is important to understand the different layers and components that organizations must account for in order to streamline internal information systems. eSigma removes some of the need for complex and costly integration architectures by allowing organizations to communicate peer-to-peer using Web Services. At the same time eSigma can provide the integration architecture for those organizations delivered as an On-Demand service.



External Systems Layer Provides a mechanism for systems beyond the corporate firewall to connect to data stores and services necessary to support your extended enterprise. Data Transmission Layer Today, and for the foreseeable future, organizations are required to support multiple data transmission standards and technologies. In order to support a real time multi-channel architecture, this layer requires flexibility and governance to support the array of devices and systems submitting and receiving requests for data. Network Services Layer This layer delivers network management and last mile distribution of bandwidth, and related network service activities, to internal systems and devices that require connectivity. Systems Interface Layer Creates a standardized, governed, interface allowing organizations to distribute the costs of integration across multiple systems and business units.	Data Component Enables standards and related technologies for data transformation. It is important to support current data types and related technologies as organizations have made significant investments in their current infrastructure. Protocol Component The shift in current integration standards from the application tier to the network in the form of XML supported protocols underscores the need to employ sound network management strategies and principles. Integration Component Allows organizations to exchange data and processes necessary for collaborating in today's On-Demand economy. Systems Component Represents the systems that need to be accounted for when designing real-time multi-channel architectures. Systems include any machine, from the trading floor to the shop floor, required to exchange information or services.
