This was my thought exactly. The article is great assuming you need to use k8s, but does leave out the important question: does your project or product require k8s and all the overhead it unavoidably entails?

Amazon's Elastic Container Service (ECS) on Fargate deployment type is probably a better option much of the time. Until you maintain your own k8s cluster (including the hosted variants on AWS, GCP, etc.) you might not realize how complex configuring k8s is.

While the AWS's ECS service may be more limited, I've found it leaves less room to do the wrong thing. Unfortunately, the documentation on ECS and the community support is inferior to k8s, but I'll accept that if I don't have to spend a whole day researching what service mesh to use with k8s and how to configure a load balancer and SSL certs.

You are right, but talking about whether to use k8s or not would make the article 2-3x longer. It is a totally different topic.

ECS (with Fargate or EC2) is awesome but one might argue that it is still an overkill for a lot of people.

Some people look for scaling, immutability, effective resource utilization and they think they NEED containers. That is not entirely true. A lot of people would do totally ok with one EC2 instance.

Either way, kubernetes is awesome, there is a big community behind it maintaining a lot of tooling, docs, how-to guides, etc. That is very valuable for a lot of people too :)

Sorry—my comment was written poorly. I think the article is good as is and agree k8s or not is a different topic. My comment intended to be a reminder for all of us reading it that we should ask more questions before choosing a technology.

I’ve found a trend in engineering (including with myself), we sometimes forget to take a step back and see the forest.

Unless something has changed recently, Fargate is a terrible choice for something that you want up 24x7. IIRC it’s like 2x the cost of similar on demand EC2 instances. It’s better for discrete tasks that can’t run in Lambda because timeout or possibly peak load (although EC2 is probably just as easy if not easier to scale).

But I generally agree with the premise that ECS is a better starting point for people just dipping their toe into containers.

2x the line item cost but generally much cheaper in terms of Total Cost of Ownership.
