One problem I've never seen mentioned regarding microservices is what happens when the organization that produced them has moved from growing to stagnating and finally into decline. If microservices ship the org-chart, what happens when that organization fails to attract engineers?

I worked for a company that microserviced themselves into a pit. We had a huge layoff which completely killed the morale of the remaining engineering staff. Over the next 3 years, more and more engineers left and the company refused to replace them. What started out as teams (~5 people) responsible for ~3 microservices ended up as teams of ~3 people responsible for ~6 microservices.

It was kind of cool to be responsible for more architecture and see how it all fit together, but the sad reality was that too many of the microservices that had been stood up were stitching together disparate data from other microservices to then perform what a single SQL query against a RDBMS was doing.
