Indeed, it has one peak period at Christmas time when it needs very significant power over a short period. Why thus be equipped all year long with a calculation capacity which will only be used for one month?

In the continuation of this chapter, we will not differentiate between the concepts of GRID and GRID computing.

Just like many other systems and architectures, GRID computing paid little attention to securing its communications.

However, this kind of solution is probably too much expensive regarding the targeted security requirements for small and medium-sized companies. Company B.
