What is CC?:
Cloud Computing describes a new supplement, Consumption and Delivery model for IT services based on Internet , and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.
As of now We don’t Understand all the Technical Terminology about CC and Fog computing .For our better understanding here goes the Simple one…
In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive.
Now this is the Era of CC and Tomorrow will be the days of FOG computing!
MAJOR CLOUD COMPUTING SERVICES
Three Primary models for cloud computing have emerged:
Let me put it this way for better understanding:
saas: You have already built a website/application(Eg: www.SIT.in). And you want to host your website/application, you go for this cloud service.
paas: You are planning to build a website/application(Eg: www.SIT.in). And you don't want to buy Visual studio/Photo shop .. Etc softwares on your own. You think if someone would rent you the software license for a week or month. paas will be best option.
iaas: You want to build a website/application, you want the license of the visual studio/photoshop and you also want to make sure that the system which you work will have certain computational capabilities. iaas comes into picture.
SAAS- software as a service
The major service given as part of Cloud Computing Services.
It is the first service in CC.
Most known and used.
