I’m genuinely interested to know when containers should be used. I’m not ignorant and understand advantages - consistent env, run anywhere, fast startup time, etc. But there is also considerable cost involved with increased complexity, educating devs, hiring experienced DevOps, etc

I have over 15+ years of professional development experience and AWS experience and I understand the scale.

Our company has 20-30 instances used by 5-6 services. We use terraform/ansible to deploy infrastructure so deploys are pretty reliable and repeatable. So I am genuinely interested to understand if it’s worth going container route?
