The installation and usage of superwerker is free of charge! The project and all included components are available as open-source and provided using the MIT licence.
Of course, costs will be incurred by the AWS services superwerker sets up. For smaller environments, the monthly costs will be less than $10.
The goal of superwerker is to provide you with a set of well-configured AWS services. These services come with their default pricing depending on the AWS region you use:
As a rule of thumb: The costs for these services will grow with the number of AWS accounts and the number of workloads (EC2 instances, databases, Lambda functions, …) you use.
In our experience from multiple customer engagements, it is cheaper to setup a multi-account AWS environment the right way, the first time, than to try and migrate active workloads from an established single-account setup to a multi-account setup, i.e. do it right, do it once and you can save time, money and effort later down the line.
