Grid5000 structure

In grid5000, we have found nine sites with one or more clusters in each one. Each site has an access machine (user@acces.site.grid5000.fr) and its own user space. Unfortunately, not all sites accept our image (each cluster has its machine type, and we must make an image for each machine type) and not all sites accept a direct connection to the "access" machine with our user. Furthermore, the user space (/home/yoursite/youruser/) is not shared between sites and not all sites have the same service structure (oar, kadeploy, etc can be served in one or more machines, for example). Figure 2.1.1.

To avoid these difficulties, the eWAN deployment tool is connected to a site and can deploy another one. The images are read from each site when it is necessary (with kadeploy tool). An example on the figure 2.1.2.
