We are in 2021 now. So, I am very sure that, by now, you must have heard the word “cloud computing” at least 10000 times 😛 .

Now a days, organization are also looking for people, who are well versed with cutting edge technologies. For example –Cloud Computing, Internet of Things, Artificial Intelligence etc.

Especially, As a result of pandemic, cloud is the way to go for everyone. In fact, It won’t be wrong to say that we are surviving without going out due to cloud computing.

So, tell me- Isn’t it a good idea to make ourselves aware of the ongoing trends to stay updated and relevant?

Of course, It is !!!

But, Before I start, Let me ask you a question.

Have you ever looked at sky thinking, where data is stored, when you heard the word “cloud” for the very first time?

To be honest, I did 😛 😛

If you are like me, comment to let me know that I am not the only one 😛

Well, today I will try my best to give you a basic overview of cloud computing. If you have any doubt, please feel free to add a comment, I will answer them as soon as possible.

What is Cloud?

In simple words, cloud is nothing but the set of computer/servers which can be accessed over internet.

Those servers are located in various data centers across the world.

Let’s understand it this way.

If you store your data in your computer. It’s called local storage. But if you store it in a server provided by someone else. It’s called storing in cloud.

Also, those who provide/rent their servers are called cloud service providers for example AWS, Microsoft Azure, Google Cloud Platform.

You, as a user, need not manage that computer/server physically. But you can use it from anywhere in the world. Provided, you have an active internet connection.

For example,Most of us sync our phone with google photos. The benefit: you may loose your phone but not your photos.

Have you ever thought, what’s the reason behind it?

Well, It’s very simple.

Those photos are stored in the cloud as a backup. You can access them from anywhere in the world.

After getting a basic idea of cloud, let’s dive into details.

What is Cloud computing?

In simple terms, cloud computing is the availability of computing resources such as storage, servers, databases, software applications etc. over internet.

  • As cloud services provide pay as you go model,you only pay for the services that you use and nothing else.
  • It helps in lowering overall operational cost by cutting the need of procuring all the required infrastructure in advance.
  • You can store as less data as you want and as much data as you want without worrying about the disk size.

Real world Example Of Cloud Computing.

If you pay close attention, cloud computing is everywhere. Especially with the rapid growth of IoT connected smart devices, everything is connected to the cloud.

Let’s have a look on the few example which are very common in our day to day life.

  • Gmail, Microsoft Office 365
  • Facebook, LinkedIn, Twitter
  • Google Photos,Google Docs,Google Drive
  • YouTube,Amazon Prime Video,Netflix etc.

Use Cases Of Cloud Computing:

Based on above example we can easily say that below are some of the use cases for cloud computing.

  • Audio and Video Streaming for ex Netflix
  • Storage, Back Up and Recovery such as Google Photos
  • Software Development and Testing
  • Website hosting
  • Virtual Desktop
  • Internet of Things(IoT)

Who is Using Cloud Computing?

Answer to this question is quite evident:

Everyone uses cloud computing up to some extent. It includes small as well as big businesses and industries.

Cloud computing gives smaller business the opportunity to start small and scale as business grows.
