It depends a lot on the app your building. If you are a startup, it definitely is much easier to build a monolith and focus on the product features. Micro-Services may not have that much upfront cost of building but as your product grows it requires lot of engineering effort and budget to maintain it. You can have an engineering team of 20 people maintaining a monolith which can serve few million customers. The same product broken into micro-services will require 4-5 teams of 8 people. It is much easier to hire for a single skillset and grow the team.
