In this article you will learn about cloud computing, categories, types, advantages and disadvantages of cloud computing including private, public and hybrid cloud. These days storing the data is becoming more tricky. We have an abundance of data that needs to be stored somewhere. Do we think that our computers and PC are sufficient for storing large chunks of data? Then what do you think? What should be the solution? From the last 7-8 years dropbox has worked well.

Cloud computing is the technique of on-demand liberation of IT resources above the Internet with pay-as-you-go pricing”

In the cloud, we can harness technology services as a substitute for buying, owning, and maintaining physical data centers and servers,  such as computing power, databases and storage on an as-required basis from Amazon Web Services which is one of the best cloud providers.

Categories of Cloud Computing

IaaS: It stands for Infrastructure as a Service. It is a form of cloud computing that provides virtualized computing resources over the internet. It is the basic layer of cloud computing. Here you can outsource a different kind of IT infrastructures like networking, processing, servers and other resources. You can pay per service in this model.

PaaS stands for Platform as a Service. it is a kind of cloud computing model in which a 3rd party provider delivers software and hardware tools. These are such tools that are required for hardware development to users over the internet. A PaaS provider hosts the software and hardware on its infrastructure.

SaaS: It stands for Software as a Service. it is a software distribution model in which a 3rd party provider hosts applications and makes them available to customers above the internet. Mainly in the SaaS model, the software is provided by cloud providers via the use of the internet. Here applications are uploaded online and you can download anytime if you are having internet facility. You also don’t need to install the software.
