How to build applications in AWS?
First and foremost, you should analyze, what is your application about? Is it something that requires you to be worried about the underlying infrastructure? Is it something that requires a database? Is it something that will require monitoring?

So, once you know all the requirements about your application, you can pick the domain, and hence choose a service.

Like for example, you want to deploy an application in AWS, which does not require you to worry about the underlying architecture, which service will you choose?

Well, in the compute section there is this service called Elastic Beanstalk. You just upload your application, and AWS does the rest for you. It’s that simple!

Of course, you wouldn’t know about any of these services without using them right? That’s why AWS came up with an amazing free-tier option.

Who is eligible for a free tier?
Every customer from the time he registers on AWS receives the free tier option, and is eligible for the same till 1 year from the time he registers.
