One benefit of a microservices/SOA architecture that I never see mentioned is that it can make you a more attractive acquisition target (if your acquirer is doing decent technical due diligence.) There's a good chance that your acquirer (a) just wants a specific part of your stack, not the whole monolithic codebase with things they don't care about, and (b) they want to integrate it into their existing systems, which are very likely written in a different language.
