what is cloud computing

what is cloud computing? 

It is the use of remote servers on the web to store to manage and to process data instead of doing it on an area server you are doing it on remote servers. So this is what cloud computing is you can store your data you can manage your data using databases or you can process your data using you happen by renting a server which has larger processing power so you can get it faster your work you can get your work done faster rather than have had to do it on an area computer which might happen slow on the opposite hand you if you wanted to try to an outsize execution work you'll have bought the server which had tons of processing power but that might have to add up because after your work is completed you do not need that computer anymore right so all of that problems could be solved with cloud computing.

why cloud computing?

why cloud computing all right so let's understand this using an example say you want to host a website right and say there is no cloud computing right now right and you want to host your website.

how would you do that so first you would have to buy servers right you need servers to host your website. that you have to keep the peak traffic in mind now what is peak traffic is basically the traffic which comes for a shorter duration, for example, you can expect the most traffic between 6 p.m. and 10 p.m. the  that is the time when people are the freest right so there's peak traffic and after 10 p.m. the traffic and decline so when the traffic booms you have to have the servers to manage them right and after 10 p.m. if the traffic declines these servers that you have deployed handle your traffic becomes idle right so you have to get maximum servers so that you don't get any problems when the traffic goes up in a peak right.

after that, since you have these many servers you have so many servers you have to continuously monitor and maintain them because you don't want your website to experience a downtime right so you have to continuously monitor them and maintain them so that your website is up and running.

these the set up that is built without cloud computing had some disadvantages let's see what were the disadvantages right so first of all the setup was very expensive because you're buying service on your own right and so us guys are not cheap they were very expensive all right so the setup was very expensive also since you're troubleshooting problems on your own that is you're maintaining your servers you're.  you have someone to handle your servers then you can actually, focus on how you can expand your application. your website ex is experiencing any downtime or are you protected with all the latest security patches and everything and then you cannot focus on security goals.

the third thing was since the traffic is varying your servers will be idle most of the time, you have to have the maximum servers so that your any kind of traffic can be accommodated within your servers right so what also like a give you a window between 6 p.m. to 10 p.m. you will experience the most traffic but what will happen 10 p.m. happen after 10 p.m. after 10 p.m. a traffic will drop and most of your servers will become idle so that was the problem all right so these problems were to be faced or these were to be solved and we solved it using cloud computing.

now came cloud computing and now we were able to solve these problems with like this so first of all our problem were that a set up was very expensive right so with cloud computing it was solved how because now we don't buy servers anymore right we just rent them from the cloud providers and we can rent them not on a monthly basis not on a yearly basis but on an hourly basis right on our new basis as well so as long as you want the servers you pay for them and when you are done with your servers, you can terminate them and that's it you don't have to pay any more so this is a very cool thing about cloud computing.

also, the scalability factor so you had to scale your resources according to your traffic right so you don't have to maintain the maximum number of servers now what you can do is you can various number of servers according to traffic so if the traffic is more you can auto-scale the servers to a number which is okay with the number of people who are trying to access your website and as the number of people who are trying to access your website goes down as the traffic goes down you can scale down from the number of servers you were having all right so scalability is again a feature in cloud computing.

 also with when you rent servers in the cloud you don't have to manage them or maintain them anymore so that is the responsibility of the cloud provider who is providing you with those cloud servers so that so now you can focus on your business goals you can focus on how to expand your application and other things it so it becomes very tension-free when you using cloud computing .
