I first began my paper by defining what cloud computing is all about.”Cloud computing is a term used to describe both a platform and type of application. A cloud computing platform dynamically provisions, configures, reconfigures, and deprovisions servers as needed. Servers in the cloud can be physical machines or virtual machines. Advanced clouds typically include other computing resources such as storage area networks (SANs), network equipment, firewall and other security devices.”(Boss, Malladi, Quan, Legregni & Hall, 2007).
Cloud computing encompasses services such as infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and Web 2.0 and other services that rely on the internet for satisfying both customers and enterprise needs. The cloud computing environment can be categorized into two areas:
- Cloud providers
- Cloud Enabler
There are two main types of cloud computing environment each bringing different
opportunities to enterprise. They are:
- Public cloud computing
- Private cloud computing.
Then, I discuss in detailed the challenges and successes of cloud computing in relation to
enterprises. I briefly discussed what “cloud” entails to sum up the first couple of pages. The
characteristics of the cloud are:
- Incremental Scalability
- Agility
- Reliability and Fault-Tolerance
- Service-oriented
- Utility-based
- Shared
- SLA-driven
- APIs
