abstract:A community cloud in computing is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally.
Using the BAH study as a guide, and assuming that communitycloud economies mimic those expected from a hybrid cloud, transitioning IT services from an agency-owned IT infrastructure to the GSA IaaS platform should deliver benefit cost ratios of approximately 7:1.
This effort by NYSE is a classic example of a communitycloud in that it is a private IaaS solution (yes, there is dedicated hosting too) designed specifically to meet the needs of a particular market and open to all members of that community.
