Abstract

Rails was made for servers. From web servers to background jobs, orchestrating the complexity of Rails in our cloud's infrastructure is hard work. We can not Kubernetes our way out of it either. There is a better way...one that is not well understood. With AWS Lambda and event-driven methodologies, we can fundamentally reinvent our beloved framework. It can change, and indeed thrive, without servers.

For Review Committee

Details

AWS Lambda is a commoditized compute platform of the future. Deeply integrated within AWS, it allows your Rails architecture to be completely reimagined atop fully managed infrastructure resources like API Gateway, SQS, S3, CloudWatch, VPC NAT Gateways, IAM, and so much more. As we explore Rails on Lambda, a pattern of evaporating concerns will become a common theme.
