What is Cloud?
Cloud is nothing but a massive huge humongous data center that is maintained by the cloud provider. For example, Microsoft or Amazon or Google for that matter, and cloud providers will make sure that the services that are offered to you will have a faster way of delivery. They innovate faster, the resources will be flexible, and you can definitely scale the resources as and when you want. Let’s learn about cloud computing.
The best past is CAPEx and OPEx really falls down exponentially. You pay for the cloud services only what you use. So, you only will have a very low operating cost. Your infrastructure will be running more efficiently and scale your business when it’s required.
What is Cloud Computing?
The definition of cloud computing is given by a body called as NISD. The NISD is the National Institute of Standards and Technology and they defined the definition of cloud computing in their publication 800-145. It says :
“cloud computing is the model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort service providers interaction.”
What does that mean? It means that I, as a cloud user should be able to create a virtual machine, create a server, maybe an SSD, or in HHD or any kind of application whenever I want. When I want to provision them, when I want to create them, probably in the middle of the night, I get an idea and you want to create a server right then, you should be able to do it. Cloud computing is very useful in these modern days because we have our own self-service provisioning portal where you can type in your username and password and then you enter into the world of cloud computing.

The Importance of Cloud Computing
Most of the business companies and small businesses use this term probably without an understanding of it. In this article, we will talk about What Cloud Computing is? What benefit it has to offer. Traditionally, if we ever have to build applications, we had to procure a lot of hardware.
For example, you will need servers, you need operating systems and their respective licenses, you will need firewalls, routers, load balancers, databases, and the list just goes endless. This means you will need a lot of capital expenditure.
Capital expenditure is the amount of money that you will, initially to procure that hardware. On the other side, operational expenditure is what you will need to maintain that hardware.
For example, heating, ventilation cost, human and manpower payroll costs, all that is operational expenditure. With traditional computing both CAPEx and OPEx, which is capital expenditure, an operational expenditure both of them were high and today with the advent of small and medium business companies and startups. We really do not have the scope to invest in hardware and licenses for the operating systems.
So, what do the startups do to a provision that infrastructure to let the business run? What they have to do? Well, they have to resort to something called as could computing. This is where the whole bunch of resources will run. So, the startups simply put the resources.
For example, servers, storage, databases, networks, software, artificial intelligence, and their respective analytics, everything into the cloud.
