====== SA2: Deployment of Infrastructure ======
SA2 aims at implementing a sustainable infrastructural model for the deployment of collaborative distributed applications in need of remote instrumentation services. The purpose of this infrastructure is not to comprise a permanent implementation, but rather to be the infrastructure supporting the application deployment for the duration of the project. Granting that computational and storage resources from both external and internal partner will be used, that the instruments will already be available to the users by the sharing entities, and that the networking links will already be in place, it becomes clear that the cost of such an infrastructure can be very low in relation to other similar efforts. The main costs related to building such an infrastructure have to do with its initialization in the specialized context of certain applications with any customizations possibly required according to the respective operational environment.

Due to the fact that SA2 will not buy or operate equipment, its final product is logically composed by a set of technical advice, international best practices and operational guidelines applicable to remote instrumentation infrastructures. These guides will be authored taking into account the different possible usage scenarios and the various different needs, in order to be directly applicable to as many different configurations as possible, and considering the possible effects of future and emerging technologies. It is the purpose of SA2 to describe an operational layer on integrating with existing infrastructures, thus acting as an extended service provider to them, but at the same time allowing for efficiency, simplicity and transparency. As the final resulting step, SA2 will implement this proposed infrastructure in a real operational testbed and support the deployment of the end-user applications described in this technical annex.

To achieve the objective described, SA2 will also take the responsibility to manage, operate and control access on the available GRID computing and storage capacity through assisting users and developers and addressing and resolving any possible arising problems. Owing to the efforts of SA2 partner and participant, computational facilities will be available to the tasks' completions: Letter of Support from HellasGrid will grant the use of a fix portion of the notable computational power and storage capacity of GRNET; seamlessly more resources will be available, thanks to the support from PSNC, while networking expertises and management will be provided by CNIT.

SA2 will take care of the described resource management process acting in several ways: the relationship between resource and network providers will be coordinated and integrated with user support, to reach agreements in terms of services enabling the infrastructure development and applications’ deployment.
End-users will benefit from SA2 in two different ways: Directly, from the support provided on infrastructure and middleware issues, and indirectly, through the description of this operational layer which can be utilised by other infrastructure providers for the deployment of applications in need of remote instrumentation services. In other words, it is expected that SA2 will provide those guidelines for Grid operations management that will ease the deployment, monitoring, accounting and trouble-shooting of middleware and applications supporting the integration of instruments on the grid.
