Next time in an interview if you are asked “What is Cloud?”
You can explain the concept using this simple Pendrive example🥳

First let’s Understand “Why Cloud” using a simple Mobile example📱

Let me explain by a scenerio.
Today by chance if you broke your mobile📱(I wish it doesn’t happen), will all your data be lost ? “NO”🙅🏻‍♂️

Because, the moment you buy a new mobile & login in it by your apple ID or gmail id, all your data get restored 🥳

It means your all photos,contacts and other detail bascially were not stored in your phone. They were at some different place.

Then where it was ? They ‘were’ and ‘are’ present in CLOUD☁️

Now “What is cloud?” lets understand it by a Pendrive example🙋🏻‍♂️

Lets go back 10 years from now, if we want to take a movie from our friend , we used to give him our pendrive.
We connect it to our computer and access the movie🍿🎦

But, if dont want to share the movie with your brother, you will hide that pendrive in a very safe private place🕵🏼‍♀️
But there is an issue, now whenever you want to watch the movie, each time you have to go to that secret place and this is a tedious work🥵

Cloud is exactly like this “Pendrive kept at a Safe Secret Place” and by using internet we can connect to that secret place from being anywhere in the world🌎🥳

All the gmail, google photos, contacts & our every important details are stored in a machine in a safe place by companies like Google, Apple & by using internet we connect to our data using our id &password🌐

Now, to store these huge data, there are bascially acers of lands used, where the DataCenters factories are setup, with all storage device & infrasturucture required to keep our data safe there🏭

These secret places are present in many countries across the globe🌎

Just like our personal photos and other personal details, we can even keep our Projects, Code, Database too in them💻👨🏻‍💻🙌🏻

This facility of Cloud Service is given by many companies like AWS, Azure, GoogleCloudPlatform, Alibaba, IBM and many others.

When we create an account in any of these Cloud Service Providers, they provide us with the secret place where we want to store our data.🕵🏼‍♀️

These places are called Region in AWS, and we should select that Area in a Region which is actually nearby to us.

Like if you are in Europe, we have option of Frankfurt, Ireland, London, Paris, Stockland.🌎

These Areas in a Region are called “Availability Zones” & there can be one or more then one AZ in a Region.

And thats all regarding the concept & presence of Cloud☁️

And for the next time, just sock the interviewer about what is cloud 😎 🕺🏻
I hope you got a bit clearity & closer about the concept, if Yes then do let me know your thoughts.

And if you share same intrest as me then lets connect to break down complex topics into an easy day-to-day life examples.🙋🏻‍♂️
Happy Learning !!
