Cloud Computing is rapidly getting momentum as an alternative to traditional IT Infrastructure. It is a way to share resources over a network in order to achieve coherence and economic of scale and aims at maximizing the effectiveness of the shared resources. The resources available in Cloud can not only be shared by multiple users but are facilitated to reallocate with every demand. So, there has always been focus on best techniques to provision the available resources in the Cloud. Cloud providers receive requests for resources from the users and allocate the resources by creating appropriate number of Virtual Machines (VMs). There are many provisioning techniques viz. Static Provisioning, Dynamic provisioning, etc. Apart from these provisioning techniques some parameters are to be considered such as minimize cost, resource maximization, response time, less SLA Violation etc in order to provision resources well. Cloud Resource provisioning mechanisms must follow some SLAs (Service Level Agreements) in order to abide by customers demand properly. There have been many articles which have taken the issue of SLA but still confusion remains about the importance of SLAs. SLAs typically are defined in terms of Mean Time to Failure (MTTF), Mean Time to Recover (MTTR), etc. This paper is a survey paper on various literatures published on Cloud Computing Resource Provisioning Techniques some of which takes SLA into account. A detailed description of some of the papers related to this topic is presented here.
