Cloud computing is a model for providing computing service such as storage, servers, services and applications, without physically acquiring them via the internet. Access to such service could be free or pay as per use. So that the organiztions does not have to spent time and cost in managing them. Many business institutions are moving towards the cloud computing due to the efficiency of services and pay-per-use pattern. This pay-per-use pattern based on the resources consumption e.g. processing power, transactions carried out, bandwidth consumed, data transferred, or storage space occupied etc. In cloud computing the client data is maintained in the data centre of a cloud provider like TATA, Netmagic, Google, Amazon and Microsoft etc. Since the data is stored on Internet Cloud the user will have limited or no control over the data, which may lead to various security issues. Since the data custody is at data centre which could lead to threats such as data leakage, insecure interface, sharing of resources, data availability and inside attacks etc. There are various challenges for adopting cloud computing such as well managed service level agreement (SLA), Confidentiality, Integrity and Availability (CIA). This research paper outlines cloud computing industry models and issues associated with it. This research paper analyse the challenges which are present in cloud computing and best practices by service providers. |
