As an AWS Cloud Consultant I see many AWS accounts. During the year I collected mistakes that I saw in each account and aggregated them to provide you my best of. It turned out that the 5 most common mistakes on AWS are:
- managing infrastructure manually
- not using Auto Scaling Groups
- not analyzing metrics in CloudWatch
- ignoring Trusted Advisor
- underutilizing virtual machines
