3 Tier Architecture on AWS using EC2 or Serverless

In this post we are going to look at a typical highly available 3 tier architecture implemented on AWS. We will look into compute options, load balancing, a few AWS database services and finally see how we can iteratively transition to serverless architecture.

In 3 tier architecture, applications are organised into the presentation tier, which implements application components that deals with user interface; the logic tier (sometimes referred to as application tier), where business logic are implemented; and the data tier, where the data associated with the application is stored and managed.
