In this chapter, we are going to discuss best practices for designing and using your microservice ecosystem. Although I am going to provide you with some best practices that I have in mind, feel free to update this as you see fit. Also keep in mind that, as C# developers, we realize that we don't always have a choice or preference in this. Even though it's our best practice, it might not be our team or our company's best practice. A good example would be that your databases have probably been in place a long time and the database administrators probably are not overly sensitive to our architectural preferences. In the end, you'll have to make the call on each one of the recommendations listed. Just do your best and think it through. Some will apply, some you won't be allowed to do, that's just the nature of how we do what we do!
