One of the major selling points of using cloud is serverless where it truly lets you build-once-and-forget with minimal maintenance overhead. Can you suggest comparable on-prem/Hetzner alternatives for the products I use: CloudWatch Logs, S3, DynamoDB, Kinesis Data Stream, Step Functions, Lambda, CloudFront, API Gateway, Athena? Having used these services in my day-to-day job, I just can't imagine myself ever going back to the old way of doing things.
