> By modularizing our front and back ends in such a way, no one person is responsible for keeping an entire app in their head all the time. As developers, it’s important to have a strong sense of our broader architectural ecosystems

Maybe I’m misinterpreting this, but those two sentences contradict themselves in my opinion.

Now either developers need to fully understand all the different micro-services, and understand how they all work together. Or developers will lose sight of the bigger architecture and end up specialising in only a few services.

But more importantly, I doubt micro-services will solve their problem of their monolith not being modular. That seems like an architectural problem that can also be solved in a monolith.

But in general, I have never seen a company that switched to micro-services, and didn’t end up regretting it a few years later.
