Microservice based architecture will continue to be used quite a bit as many weaker engineering leads have latched onto it as a way to solve interpersonal problems on their team and letting everyone have their own little fiefdoms. It creates a terrible scenario and a very dysfunctional team, but the hype cycle and a few high scale orgs mentioning it means its part of the "mainstream" now and something that ill-informed leads will be pushing for the next decade, whether it makes sense for the specific context (it doesn't) or not.
