During the last few years, cloud computing has become a buzzword on the internet. In simple terms, it is the process of delivering services hosted on remote data centers connected through the internet.
According to analysts, this market segment has a compound annual growth rate (CAGR) of around 10%, and is expected to reach USD 205.48 billion by 2018 (Source Public vs.Private Cloud Computing )
Cloud computing means that instead of all the computer hardware and software you’re using sitting on your desktop, or somewhere inside your company’s network, it’s provided for you as a service by another company and accessed over the Internet, usually in a completely seamless way
You Know What makes cloud computing different? It’s Totally managed
IT people talk about three different kinds of cloud computing, where different services are being provided for you. Note that there’s a certain amount of vagueness about how these things are defined and some overlap between them.
Infrastructure as a Service (IaaS) means you’re buying access to raw computing hardware over the Net, such as servers or storage
Software as a Service (SaaS) means you use a complete application running on someone else’s system. Web-based email and Google Documents are perhaps the best-known examples
Platform as a Service (PaaS) means you develop applications using Web-based tools so they run on systems software and hardware provided by another company.
If you’ve been researching cloud computing, you’re probably well aware of the private vs. public cloud debate. Before you decide which end of the debate you side with, it’s important to know the difference between the two
Public Cloud Computing and Private Cloud Computing
Public Cloud Computing: Public clouds such as Amazon EC2 and Rackspace Cloud have a number of trade-offs. The majority of public cloud deployments are generally used for web servers or development systems where security and compliance requirements of larger organizations and their customers is not an issue.
Private Cloud Computing : Private cloud hosting, on the other hand, by definition is a single-tenant environment where the hardware, storage and network are dedicated to a single client or company.
