A common consideration when building modern applications is whether to 'go serverless' and build with FaaS services like AWS Lambda or Azure Functions. Or whether you should build with containers and run them using services like Amazon ECS, Azure Container Apps or even Kubernetes.

Whilst this conversation is valuable, most large software systems will have use cases for both. Blindly opting for one over the other risks not always picking the right tool for the right job.

During this talk, you will understand the key differences between functions and container-based workloads and, importantly, how to run them in a serverless way.

By the end of this talk, you will have a clear set of heuristics for when to choose containers and when to choose FaaS. As well as best practices for running both in production.
