Cloud computing refers to delivering the computing services over the internet. These services are servers, storage, networking, software, etc. Cloud providers are the companies which render the service for a price, similar to any other utility services.
What Can You Do With Cloud?
Well if you have been using an online CRM, office application, playing games, etc. it is entirely possible that you might be using the services of cloud computing behind the scenes. Although cloud came into existence lately, yet it is being used by global corporations, government agencies, and many other organizations. There are many things you can do with a cloud; you can create new kind of applications and services, store, back-up, and recover data. You can host your websites and blogs, stream video, and even deliver software services on demand without thinking much about cloud computing security.
IaaS, PaaS, or SaaS
The various cloud computing fall into three broad categories:
- IaaS, Infrastructure as a Service
- PaaS, Platform as a Service

Infrastructure as a Service
It is the simplest form in which you rent the IT infrastructure from a cloud provider.
Platform as a Service
It refers to cloud computing services that provide an on-demand environment for developing applications. It creates an environment in which developer don’t have to think about underlying computing requirements.
Software as a Service
It is a method for delivering software application on the internet. The service is a subscription service chargeable on an hourly, daily or monthly basis.
Various Kinds Of Cloud Deployment
Public, Private & Hybrid these are three different ways to deploy cloud computing resources. Let’s take a look at them one by one.

Time to deploy vast amount of computing resources is very less. It helps business in tackling scale-up and scale-down of IT operations.
Easy To Deploy Across The Globe
Multinational organizations face many challenges in expanding in the areas where creating IT infrastructure is difficult.
