Abstract
Cloud computing laid the conceptual and infrastructural foundation for tomorrow’s computing that is being widely used around the world. Earlier in order to host a website, create an application or store large data consuming resources we had to buy a stack of servers. These servers were very costly as well as needed monitoring and maintenance. Cloud computing uses virtual resources for sharing data. For instance, companies like Amazon and Google provide storage and computing resources over the internet where we can store, manage and process our data. It is a time saving and cost efficient system which takes care of bandwidth and also provides data movement, transactions and storage information. There are various data centers of a cloud provider like Microsoft, Google, Amazon, VMware etc. This paper presents a comprehensive review on cloud computing and its security issues in reference to cloud infrastructure.
