I think there's a middle ground, it's more a domain driven design centric view of the world. Each domain is a monolithic style application with services that run in their own processes and communicate via some type of messaging infrastructure e.g. postgres, redis, zeromq, etc. The critical aspect of this approach is well-defined message schemas and versioning. The services can be spun up with a Procfile or built into a container. As you move towards container based infrastructure, other services like instrumentation, monitoring, and aggregation of logs are required.
