When you're in the process of adopting microservices, you have to build the entire ecosystem in order to make them work. You need to look for new ways to connect the distributed systems, secure them, and make them work as a whole. Writing just one application to do all this is easier. However, after a few months, the other microservices will reuse all the work that you put in at the beginning, meaning the process speeds up significantly. To take full advantage of this way of creating systems, it is important to try out new ways of deploying applications, making them scale on demand, monitoring them, and logging them. It's also important to review the functionality of microservices that handle the core of the business. These systems sometimes end up being semi-monoliths that should be split up in order to make them easier to manage.
