In the same vein I don't think kubernetes and containers are worth the hype either. In fact, I'm mostly convinced the cloud native foundation is solving imaginary problems that most people don't have.
I have to disagree. While as the article stated microservices are suited for a very large scale and specific scenario, in my experience containers solve problems common to even the smallest personal website deploy. They basically standardized a packaging format and configuration best practices, while before you probably had your zip, jar o executable that you had to copy to a server, unpackage/drop into an application server/run, changing obscure files to configure it for production use, now from an operation standpoint it doesn't matter how your application is put together. We have centralized repositories (container registries), a single method of distribution (docker pull/push), a single way of starting an application or a service (docker run) and a single way or changing configurations (via environment variables). I migrated old Rails apps from a manual deploy to a containerized solution and even if they are simple monoliths used by maybe 50 people it made iteration and deploy so much easier and faster I would never go back.
Kubernetes is another topic altogether, it is only useful when you have more than 30/50 containers to handle. But it can really help you scale out, even if the application is a simple monolith (monoliths still have to scale to accommodate traffic, spinning up more instances behind load balancers predates or microservices) being able to handle container lifecycle and scaling from a single point, having centralized monitoring and logging and easily scale to multiple machine if needed can really bring value to a business.
