We're being pushed to move to Kubernetes/EKS (or, ECS as a plan B) away from Elastic Beanstalk. Elastic Beanstalk does the job but it's slow to deploy things, it's inflexible, and the Amazon AMIs that underly them are riddled with ancient packages that infuriate security scanning security people. Are we making a mistake moving to Kubernetes instead of re-designing an infra-as-code using docker+terraform+ansible+a CI pipeline? We run a client-facing app but it doesn't have super low latency requirements, although it does need to be able to scale up to run jobs. Something else. I have to be honest, the complaints here about "people are doing it for their CV," while true, need to be understood in the context of, it's extremely hard to move jobs without significant kubernetes and Docker experience.
