Bottle-Necks of Cloud Security-A Survey

A tremendous necessity has enlarged its domain in security in cloud computing. This paper is a survey more specific to different security issues that are raised in cloud computing environment. However, cloud computing is one of the recent research immersing trends for hosting and delivering services over the internet. It provides software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS) to the end users. Cloud Computing enables ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. It also provides scalability for applications by providing virtualized resources dynamically. Apart from these features cloud computing has several security challenges like storage security, data security, network security and application security.
