Computing has become more invisible, widespread and ubiquitous since the inception of Internet Things (IoT) Web Things. Multiple devices that surround us meet user’s requirements everywhere. Middleware Framework (MF) designs have come into existence because rapid development interactive services in Heterogeneous Systems. This resulted delivery throughout Environments (HE). Users are given free ...

Middleware is necessary for developing distributed systems. Developers compose them from reusable services provided by standard or proprietary middleware infrastructures, including the Object Management Group’s Common Object Request Broker (CORBA), Microsoft’s Distributed Component Object Model, Sun Microsystems’ Java Remote Method Invocation, and related services, to deal with nonfunctional re...

Supporting the varied software feature requirements of multiple variants of a software product-line while promoting reuse, forces product line engineers to use general-purpose and feature-rich middleware platforms. However, each product variant now incurs memory footprint and performance overhead due to the feature-richness of the middleware along with the increased cost of its testing and main...

Diversity in distributed applications leads to diversity in distribution models, and hence in middleware. However, large systems may need different types of middleware and interoperability between them, requiring “Middleware to Middleware” architectures. We have introduced the schizophrenic middleware concept as a general solution for interoperability between distribution models. PolyORB, our i...

Middleware islands occur when an enterprise uses different middleware that doesn't communicate easily. They can arise because different middleware is used where it is most appropriate in an enterprise. Or the mix may have arisen for historical reasons, such as keeping up with new middleware developments, or because certain bought-in applications introduced their bundled middleware into the ente...
