There’s another option that isn’t quite mentioned which is the PaaS approach. I wanted to use Lambda/Serverless for our application (which will fall into the complex business application category). However, as you rightfully mentioned, I started to run into the issue of managing too many Lambdas and managing dependencies and shared code between them, etc. I could tell the tools aren’t ready to support a complex app yet.

Our solution so far has been to use AWS Elastic Beanstalk. The service helps you easily configure and deploy an application, and acts “serverless” in the sense that the scaling and load balancing is invisible to you. AWS could potentially upgrade the infrastructure that EBS uses and start using containers or even Lambdas and your application would perform better and better automatically.

Is there a good reason you can see to use Kubernetes over this approach?
