One of the most common post by newcomers to AWS seems to be bill shock or unexpected charges.

Some of this is from using a service with out knowing the costs or forgetting to shut something down and incurring costs for longer than planned.

Some however is where accounts have been compromised and resources used by someone else.

So what can you do to prevent this?

This article will look at ways of securing your account and managing your costs. It is a high level article and doesn’t go into every service mentioned in detail, however it should give you enough to protect yourself and point you to further resources.

😕 But why do so many people put things in public subnets that don’t need to be?

In this article I’ll look at what I think should be in public subnets and why you try not to put anything in a public subnet you don’t need to.

In this part we will look at how to use the Well-Architected Framework and also some resources to help you further understand the framework and review process.

How not to use it

Firstly I think we should look at how not to use the framework and review as often I see people getting dishearten or resenting the review because it is used in the wrong way.
