ISG LibraryEventsClients and Case StudiesServicesAbout ISG
ISG has completed a large number of projects that included a variety of commercial middleware products. The majority of these projects required to extend the functionality of the selected products through custom development. ISG has isolated common middleware services into three reusable frameworks:

Resource Management Framework (RMF) is a comprehensive development, deployment and management framework that complements popular CORBA-based Object Request Brokers (ORB).

RMF is not a new middleware solution; rather, it is a set of classes provided to application developers and a number of processes that integrate with industry-standard CORBA products to provide scalability, manageability, monitoring, fault-tolerance, high-availability and containment RMF framework functionality covers the client- and server-side application implementations.

RMF is designed to enable resource management and monitoring for new, as well as existing, application components. It provides a highly scalable and flexible way for a client to locate, create and delete server resources in a location transparent manner. The server-side functionality covers development, deployment and management of the application resources.

RMF uses functionality such as monitoring, security, application instrumentation and load balancing to achieve its goals. RMF also provides applications with a container that provides life-cycle management and thread management.

Most distributed applications developed today are implemented using a three or more tier architecture. In many cases, the application business logic that resides in the middle tier needs to access legacy applications. The Legacy Encapsulation Framework (LEF) provides mechanisms to integrate legacy systems (such as mainframe COBOL applications) with new, object-oriented middle-tier components.

It generates standards based interfaces (CORBA and EJB) that encapsulate function calls to procedural legacy applications. LEF shields application developers from the middleware layers that connect the mainframe, it provides automatic data type conversion and intelligent mapping of exception semantics.

LEF allows to aggregate business functions residing in legacy applications into new middle-tier business components, thereby freeing new applications from the presumptions dictated by existing designs. This highly structured approach to legacy integration isolates the effects of changes to one application on the rest of the system and enables controlled migration to a component-based architecture.

Years of experience, translated into Best Practices, transformed into ready-to-use frameworks that complement widely adopted middleware products
