This is the first image that comes in your mind when you hear about the word cloud but in the technological world, the meaning of cloud is something different from this. Mainly we used two flavors of the cloud in our life first is public cloud and the other one is the private cloud but to understand this we have to know about what exactly the cloud is?

Cloud is the most trending topic between the youngsters but why this word is so much famous because according to a survey of google at the end of 2019 approx 49.1% of companies are using cloud computing in their business but in next 10 years means 2029 this percentage is increased from 49% to 75.5% which is a very big number. Almost all the big companies
are using cloud computing for their business but do we know what exactly cloud is let's discuss Before under this we have to know that why we need a cloud or why someone made cloud. As we know anything we made or exist in our life solve our problems directly or indirectly the cloud is doing the same it also solves big issues of IT industry. But what the issue is?

Everything in IT industry is business and our business runs with the client  when our client came our business is good and if not it's not good but the question is that where are client came for getting our service in our shop - no, in the market - no or at our home - a big no, so where the client came for connecting with us. The client will come to connect with us on our OS (operating system) typically known as a web server. If the client came on our web server it means that we have to launch our web server but we have different ways to launch our web server. For our business, we have to choose the best way by which we can provide the best service for our clients and also in limited money. For this now a day we use cloud computing but behind cloud computing, we use containerization.

But the question came about how we use and why we use Cloud Computing for understanding this we have to discuss more on a web server. For launching our web server we need RAM and CPU also known as a computing device for using this computing device we need to buy this or we can take this computing device on rent. And you have to know that for industries we need hundreds of computing devices and this cost very high which can't afford by the small companies or start-ups  so some companies make solutions for these. These companies provide computing devices on rent and these companies are known as cloud com-
putting companies or service providers like AWS, GCP, Azure, etc.  Before cloud companies have to buy their infrastructure and then set up their own. Web server and after that companies have to work on their main application. Can you imagine how tough this task is to buy the computing device and then launch a web server and in the end, we have to manage our site or application? Our whole business depends on the site or application and we are the least concerned
about it so our chances of loss in business are very high. And if our site runs well we also need experts to manage it like Security Specialist, Infrastructure, the management team and many more these all tasks are very tough and tedious for a fresher or Startup guys. So these are some benefits of the cloud and the reason why we use the cloud.

After knowing the cloud next question came in the mind of people that ook we know cloud but which one is better for us and how we select the cloud. There might
be two categories who are reading this article first one Student and the second one are users or working professionals who want to use the cloud. So both have different accept for using the cloud-like Student wants to learn better one so that they can get a good job and working professional wants that they can use the services
effectively and cheaply so that they can make maximum benefits for their business. When students are going to learn they are very much confused because there are so many clouds and we have to choose a cloud for our starting so how we choose the best cloud for us. The answer is you can choose anyone because the concepts
of all the cloud are same like your programming languages the only difference is that the name of the services and the cost for using that services are different like in AWS computing service is called ec2 and in the OpenStack, it is known as a nova. So you can start from anywhere and after learning a cloud you can easily
switch from one cloud to another cloud. For the working professional this is a big question because in an industry no one uses single cloud due to many reasons like dependency on a single cloud, cost increases and migration is difficult so they always use cloud from different vendors and also they use hybrid cloud for their data
security don't worry about these words I will cover these topics in a different blog in details. So we can not discuss all these aspects in this blog because if I discuss
this I will be very big so that everyone will scare by seeing it.

If you think that you use storage for saving your data in your mobile like photos, videos and chats these are all come under the cloud than you are right but these all are the subdomain of the cloud computing which is discussed above. Many companies are providing this storage with the use of cloud computing like google drive, dropbox mi cloud, etc. these are known as storage as a service. Basically, if you are a tech guy or a guy who is interested in the tech than you should know what actually the cloud is, why we use the cloud, and how it works. Here actually means the right knowledge of cloud computing  because
knowing the right thing can only help you to create a better or a new use case and you can use it effectively.
