“Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change. “[Source: azure.microsoft]. 

Before cloud technology came into the world of computing, the only option was to have your infrastructure [especially hardware] in a “solid state.” That means you had to have your servers, storage, and databases on the ground. 

Only big companies could afford to have all that. 

Small companies couldn’t go close to that kind of technology. 

Cloud computing eliminates the need for you to have those advanced technologies physically.

So, instead of building your own from the ground up, cloud computing makes it possible for you to access those services and infrastructures [hardware, software, and expertise] over the internet for a reasonable amount of money, as compared to if you had to purchase everything yourself — deployment and maintenance.

Here are the top benefits of cloud computing, according to Microsoft Azure: 

Cost Efficiency

Global scale

Better Performance 

Strong Security

Great Speed

Better Productivity 

Reliability

Cloud computing has made it easy for entrepreneurs without enough resources to bring their ideas to life.
