RESUMO

This PhD thesis presents investigations, models and implementations of a computational grid middleware named Grid Anywhere. This platform aims at allowing the build of computational grid systems, which enable the increase of the number of participants as consumers and resource providers. In order to do this, new solutions are presented to manage security policies, load applications, host objects, execute remote methods, develop application and alternative transport of SOAP messages in a flexible way (using the interactive digital television system and inserting one SOAP message inside another document of this same protocol). As applications of this middleware, two different architectures of computational grids were created. The first one enables an environment to share resources that are used as infrastructure to provide platform as a service (PaaS) in a cloud computing system. The goal of the second architecture is to increase the computational power of desktop computational grid systems using digital television receivers (set-top box) as resource providers, where the distribution of objects and SOAP messages occurs via broadcasting. The models were validated by means of real tests using the respective implementations, which showed that the platform is functional. Such implementations provide software products that help the innovation and development of computational grid applications and also others types of distributed systems
