In grid computing, a virtual organization (VO) refers to a dynamic set of individuals or institutions defined around a set of resource-sharing rules and conditions.
The collaborations involved in grid computing of the early 2000s lead to the emergence of multiple organizations that function as one unit through the use of their shared competencies and resources for the purpose of one or more identified goals.
It comprises a complex network of smaller organizations which each contribute a part of the production process.
Boundaries between organizations are fuzzy; control is generally by market forces, reinforced by the certainty of long- term contracts.
The XtreemOS project promised to support virtual organizations.
