I think these problems are not about software development, but are infrastructural and architectural. Lack of good people to handle those things is certainly a problem. But you do need quite a bit of infrastructure for microservices, for resilience, for continuous integration and all of that paired with some good architectural decisions. Resilience is probably the hardest thing among them, as it requires some expertise in distributed systems, operations, infrastructure, so you wouldn't do something, that has almost no impact, but requires a lot of engineering effort.
