Most people reading this are probably using the free tier in AWS, well if you’re not careful you could go over and accidentally bill yourself. In order to avoid this you can create a budget in AWS. You simply select your account in the top right info, select billing information, and then in the right hand side it gives you the option to create a budget. You can use a template or create one from scratch. I personally created a budget that will send me an email alert if I am charged above a certain amount. I hope this information was useful!
