Bastion

Bastion is a customizable, open-source Backend-as-a-Service that gets deployed to your AWS account. Bastion allows you to set up a functional backend quickly and with minimal configuration. Unlike a managed BaaS, you’ll have full control of all the code and data, but with Bastion you can still take advantage of the numerous services provided by AWS. Furthermore, because Bastion integrates with AWS Lambda Functions, you can easily modify the behavior of your backend to fit your specific use case. And because Bastion runs using AWS infrastructure, your backend will be able to automatically scale when more resources are required.
