CHARACTERISTICS OF OPEN GRID SERVICES ARCHITECTURE.

This paper presents the OGSA - Open Grid Services Architecture, describes the basic SOA standard of distributed Grid architectures, highlighting the architecture of the OGSA standard. There are issues related to the mobility and security of the OGSA framework, as well as the evolution of technologies involved in applying the OGSA standard to P2P environments. Grid services are described as an extension of Web service technology. In addition, the transition from the OGSI standard to the WSRF standard, is the successive implementations of the OGSA framework, is described. This also addresses the OGSA environment security issues for distributed architectures, discussing recent initiatives to create a specific and tailored OGSA environment for Web applications and security requirements specific to this transition.
