Amazon Web Services is one of the most important cloud service providers these days. AWS cloud has many management tools, that make it even more robust. Now they are providing us with the best quality cloud solutions with more than 200 cloud services.

AWS is more secure and reliable. AWS is the most demanded cloud service provider because they provide the best infrastructure and have many applications, its secure and cost-effective services. Let’s discuss this more in detail.

What is cloud computing?

Cloud computing is a data storage service or computing service provider that we can run from anywhere on the Internet instead of hosting those in the local servers. Cloud computing is not static in one place.

Cloud computing is adopted worldwide nowadays. The most important benefit is the reduction of liabilities as everything is managed by the service provider. Cloud computing is not just for storing data, it has hosts of other services and options.

We have even the option of scaling up and down the service and storage as per our demand in the cloud with minimal time and price within minutes as compared to local servers which take a lot of time and effort to scale up and waste money when we scale down.

What is AWS Cloud Computing

In cloud computing, we have flexibility in accessing data anywhere throughout the globe where we have internet facilities.

Cloud computing allows us to use applications as per our requirements along with ample storage space, we have also great security in the cloud as well to safeguard sensitive data stored.

We can also handle TB and PB of data in the cloud as we have no limit on storage space and processing capabilities.

With Cloud, the prices are very cheap as compared to on-premises setup which needs a lot of planning and budget allocation.

That’s the reason many big-shot companies are opting to move to the cloud. Along with all this data security and privacy are also well maintained in the cloud. So now the question that arises is How much does AWS Cost?

What is AWS?

AWS is Amazon Web Services. AWS is a key player in providing cloud solutions to major clients across the globe. AWS provides us with a host of services. AWS is very secure, it keeps our data safe. AWS provides us with flexibility, scalability, cost-effectiveness, and security.

With the flexibility of AWS, we can choose as per our wish.

  • Which operating system do we want
  • What languages to use?
  • How many instances do we need to create?
  • How much storage is required?

AWS provides services and charges as per usage. It’s scalable. We can choose the instances as per our requirement, increase or decrease the number of instances as per the demand on the go and we pay only as per our usage.

So that means we can scale up and scale down as well. Scaling horizontally and vertically is also an option we get in AWS.

Why AWS is the best?

In the absence of AWS in order to increase the capacity, we had to buy servers and set up infrastructure which demands time and a lot of money and manpower. Then comes maintenance which also needs money and manpower.

When the demand goes up again then we have to go through the same cycle again, don’t you think it’s too much time taking and hectic?

Let’s think about a situation where suddenly the demand goes down drastically, so it’s the ultimate waste of money and resources.

Think about the scenario when we have a sale on an eCommerce site, the demand goes up drastically with the users increasing instantly and suddenly it goes down once the sale ends.

The answer to all the above questions is AWS, with AWS in place we can handle all these with just a click of buttons, that’s true!! AWS has that flexibility and pricing with which we just have to pay for what we use the AWS resources for that span of time only, of course, it’s very secure. Isn’t it wonderful!!
