Cloud computing currently plays a crucial role in the delivery of vital information technology services. A unique aspect cloud is middleware and other related entities that support applications networks. specific field research may be considered, particularly as regards services at all levels, thus needs analysis paper surveys to elucidate possible study limitations. The purpose this perform sy...

Middleware typically provides abstractions for common tasks such as atomicity, synchronization and communication with the intention of isolating the developers of distributed applications from lower-level details of the underlying platforms. Although one would like to develop generic middleware services which can be used in a variety of different applications, efficiency considerations often fo...

This dissertation provides constructive proof, through the implementation of a middleware, that distribution transparency is practical, generic, and extensible. Fault tolerant distributed services can be developed by using the failure detection abilities of the middleware. By generic we mean that the middleware can be used for many different programming languages and paradigms. Distribution for...

With the growing interest in service-oriented architectures, achieving seamless interoperability between heterogeneous middleware technologies has become increasingly important. While much work investigating functional interoperability between different middleware architectures has been reported, little practical work has been done on providing a unified and/or interoperable view of security be...

The internal functionality of middleware is highly variable and thus, well-constructed integrations are difficult to perform without understanding the architectural style of the middleware and the adaptive connections needed make components in an application integration " middleware-aware. " In this paper, we use IBM's WebSphere® MQ to implement two different architectural styles of integration...

Middleware provides simplicity and uniformity for the development of distributed applications. However, the modularity of the architecture of middleware is starting to disintegrate and to become complicated due to the interaction of too many orthogonal concerns imposed from a wide range of application requirements. This is not due to bad design but rather due to the limitations of the conventio...

Despite increasingly emerging applications, a primary concern for blockchain to be fully practical is the inefficiency of data query. Direct queries on take much time by searching every block, while indirect database greatly degrade authenticity query results. To conquer problem, we propose Verifiable Query Layer (VQL) that can deployed in cloud provide both efficient and verifiable services sy...

Migrating distributed applications from one middleware to another is difficult in legacy software systems where middleware functionality is spread across and tangled with business logic. In these systems, the old middleware code has to be removed before the application is refactored and the new middleware functionality is added. However, when distributed applications are developed in an aspect-...

Effective design of middleware-based systems requires modeling notations that allow the use of process-interaction schemes provided by different middleware packages directly in designs. Traditional design notations typically only support a fixed class of interprocess interaction schemes, and designers wishing to use them for modeling middleware-based systems must devote significant effort to en...

As the importance of robot software has increased, much research about robot middleware has been performed extensively during the past several years. Most of these systems are based on client-server and service oriented-based system architecture. Robot middleware usually provides executable environments that robot software developers are easily able to develop flexible robot services through va...
