Cloud computing refers an automated on-demand self-service, that allows a pay-per-use model on shared resources. Different field especially for business in companies are relying on cloud storage. Scalability is considered a significant factor for securing the cloud environment to overcome the hacking problem. In cloud paradigm, scalability is that one of the major benefits and, particularly, which makes different to an “advanced outsourcing” solution. Among all the exciting feature of cloud computing is Auto-Scaling that recommends the clients the comfort and easy to utilize the resources as per their demand and expectations. This paper emphasizes the auto scaling method and presents an outline of cloud computing. In this paper, a study of cloud scalability, issues of scalability, auto scaling techniques and their algorithms such as a proactive auto-scaling algorithm (PASA) and a dynamic auto-scaling algorithm (DASA).
