A Review on SLA-Based Resource Provisioning in Cloud

Traditional IT infrastructures are gradually becoming obsolete and an alternative way to store, manipulate, and retrieve data. Namely, cloud computing is gaining momentum to replace the traditional computing environment. Sharing of resources over a distributed network is the main motive of cloud computing in order to provide consistency and reliability of the shared resources while keeping a check on the monetary factor involved. The resources available in cloud can not only be shared by multiple users, but are also be facilitated to reallocate with every demand. So, there has been always a focus on best techniques to provision the available resources in the cloud. Cloud resource provisioning mechanisms must follow some service-level agreements (SLAs) in order to abide by customers demand properly. This paper focuses on various research works undertaken on cloud computing resource provisioning techniques by taking SLA into account.
