Serverless apps rely on a diverse set of services offered by the cloud. It's no longer a simple command that you can run on your machine. Instead, you need to configure things like compute, database, object storage, entry points, user directory, and permissions using a dedicated service. In AWS, that means you'll use Lambda, S3, DynamoDB, IAM, Cognito, and CloudFront even for a simple webapp.
This can feel daunting. Where to start from the >200 services AWS offers?
These books and courses are there to help you with your serverless journey. From the foundational concepts to specializing on some aspects, you'll find well-researched, in-depth content with plenty of examples. They are designed for developers who write code.
