Question

What is cloud computing? Explain security in cloud computing?

Answer 1

Cloud computing is shared pools of configurable computer system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility.

Cloud security encompasses a broad range of security constraints from an end-user and cloud provider's perspective, where the end-user will primarily will be concerned with the provider's security policy, how and where their data is stored and who has access to that data. For a cloud provider, on the other hand, cloud computer security issues can range from the physical security of the infrastructure and the access control mechanism of cloud assets, to the execution and maintenance of security policy. Cloud security is important because it is probably the biggest reason why organizations fear the cloud.

The Cloud Security Alliance (CSA), a nonprofit organization of industry specialists, has developed a pool of guidelines and frameworks for implementing and enforcing security within a cloud operating environment
