Abstract: “Day by day cloud computing is gaining popularity and people are connecting applications in cloud using any device in any location. Infrastructure as a Service (IaaS) is a vital service in cloud computing which is developing fast. It offers resources such as virtual machines, storage, firewalls and network devices to the client machines. Deploying applications and managing infrastructure services which supports multiple environments is becoming expensive in cloud. The third party providers have its influence in cloud environment for deploying and delivering applications over a distributed network. This advanced growth in cloud computing makes the computing infrastructure certainly available in a very adaptable and dynamic pay-as-yougo model. This paper presents the comparative study of deployment models in IaaS and features in it.”
