5 AWS mistakes you should avoid

5 AWS mistakes you should avoid” is a rather opinionated piece on what you should and shouldn’t do with your infrastructure, especially, when using AWS.  Here’s an example:

A typical web application consists of at least:

  • load balancer
  • scalable web backend
  • database

and looks like the following figure.

typical-web-application

This pattern is very common and if yours look different you should have (strong) reasons.

It’s all good advice in there, but it comes from a very narrow perspective.  The “mistakes” are:

  • managing infrastructure manually
  • not using Auto Scaling Groups
  • not analyzing metrics in CloudWatch
  • ignoring Trusted Advisor
  • underutilizing virtual machines
