Virtual Environment in Cloud
In cloud computing, the word cloud (also phrased as \"The cloud\") is used as a metaphor for \"The Internet\", so the phrase cloud computing means \"A type of Internet-based computing\", where different services - such as servers, storage and applications - are delivered to an organization's computers and devices through the Internet. The cloud is going to drive the next generation computing. The main aim is to present hypervisor (i.e. the Virtual Machine Monitor (VMM) in cloud architecture), the types of hypervisors, security issues regarding hypervisor and measures to secure hypervisor.
