NIST has released the final definition of Cloud as they see it. Even though all standardization bodies and the majority of enterprises already adopted this definition, it is good to see more attention drawn to it. As the cloud computing market is growing, existing cloud deployment models are altered in attempts to create new markets. NIST again manages to stabilize the cloud definition market by re-stating the definition as they see Cloud: saas/paas/iaas services in private/public/hybrid/community deployments with the 5 essential characteristics.
