What is Cloud Computing?
As per wikipedia
The phrase “cloud computing” originated from the cloud symbol that is usually used by flow charts and diagrams to symbolize the internet. The principle behind the cloud is that any computer connected to the internet is connected to the same pool of computing power, applications, and files. Users can store and access personal files such as music, pictures, videos, and bookmarks or play games or use productivity applications on a remote server rather than physically carrying around a storage medium such as a DVD or thumb drive. Almost all users of the internet may be using a form of cloud computing though few realize it. Those who use web-based email such as Gmail, Hotmail, Yahoo, a Company owned email, or even an e-mail client program such as Outlook, Evolution, Mozilla Thunderbird or Entourage that connects to a cloud email server. Hence, utilizing desktop applications to connect to your cloud email, is still considered a cloud application.
So Cloud computing refers to the provision of computational resources on demand via a computer network, such as applications, databases, file services, email, etc. In the traditional model of computing, both data and software are fully contained on the user's computer; in cloud computing, the user's computer may contain almost no software or data (perhaps a minimal operating system and web browser only), serving as little more than a display terminal for processes occurring on a network of computers far away. Common shorthand for a provided cloud computing service (or even an aggregation of all existing cloud services) is "The Cloud".
What are the services available in Cloud?
There are broadly 3 types of services that are available via cloud
a.) IaaS (Infrastructure as a Service, like Amazon Web Services)
b.) PaaS (Platform as a Service, like Microsoft Windows Azure)
c.) SaaS (Software as a Service).
What are the various types of Cloud?
There are 2 types of cloud:-
a.) Public Cloud
b.) Private Cloud
I will try to explain more about Iaas, PaaS and SaaS and also more about various types of cloud in future blogs..Keep posted...
After reading this blog I searched more about cloud computing and developed a picture that we have been using cloud computing in one or the other form as we use resources from other computers through web or LAN. But it is coming in more advanced form now. Is it the write line of thinking?
ReplyDeleteThis is really a nice introduction about Cloud Computing.Though i have heard the phrase before but was afraid of getting into it as surfing on internet and getting the extract is a tough job. So thank you sir for giving me a start. I am waiting for more on this..
