  The new era of computing called Cloud Computing allows the user to access the
cloud services dynamically over the Internet wherever and whenever needed.
Cloud consists of data and resources; and the cloud services include the
delivery of software, infrastructure, applications, and storage over the
Internet based on user demand through Internet. In short, cloud computing is a
business and economic model allowing the users to utilize high-end computing
and storage virtually with minimal infrastructure on their end. Cloud has three
service models namely, Cloud Software-as-a-Service (SaaS), Cloud
Platform-as-a-Service (PaaS), and Cloud Infrastructure-as-a-Service (IaaS).
This paper talks in depth of cloud infrastructure service management.
