Gridification of a cloud infrastructure through virtualization technologies and related security challenges
Davide Salomoni (INFN, Italy)
Modern infrastructures for distributed computing can be divided into the two main categories of grids and clouds. While providing roughly the same services, they differ greatly in the way these services can be accessed. The former mainly rely on X.509 certificates as user-visible authentication methods and is a widely distributed system, while the latter can potentially use several authentication methods, but are usually limited to a single site or organizational entity.
The presentation will first explain how computing resources can be uniformly accessed via either grid or cloud interfaces, using virtualization technologies managed by a software named WNoDeS (Worker Nodes on Demand Service) INFN is developing, and which has been put in production at the INFN Tier-1 Computing Center. It will then proceed to describe details of a new infrastructure permitting users to access grid resources as if they were cloud resources.
To achieve this, some newly developed infrastructure components are needed. These components need to allow: transparent translation of various types of user credentials into the X.509 format, communication between the OCCI layer and the grid infrastructure, and publication of cloud-type resources into a grid information system. A cloud user will then have access to resources made available by distributed grids, thus moving the scenario a step closer to the cloud ideal of having infinite resources.
