Cloud computing provides an environment, where a large pool of systems are connected in networks (i.e., private or public), to provide dynamically scalable infrastructure for storage of application, data and file. Resource allocation is a way to assign resources to the needed applications. Cloud service providers use lease manager for better resource allocation. Haizea is a lease manager that takes lease request and makes scheduling decision. The authors describe cloud computing and its properties, different leases in Haizea and scheduling of resources in Haizea.
