Start with a Monolith! Why? Finding boundaries is a difficult thing to do and even harder to get right. Having to define those boundaries up-front for a microservices architecture is a recipe for additional and unneeded complexity. If you develop a loosely Coupled Monolith by applying the same principles when developing Microservices, you’ll be in a better place to refactor and change your boundaries as you gain insights.

Splitting up a Monolith into Microservices is not an easy task. It can be broken apart into multiple steps. Defining boundaries and capabilities are key. Depending on how much coupling you have within your Monolith, and how you couple is a big factor in how challenging this process will be.

With well-defined boundaries, you can scale out each boundary independently, including the database. Boundaries within a system are so important, regardless of Monolith or (micro)Services, and give you more options for scaling.
