Summary
In this chapter, we have discussed the pros and cons of building microservices and seen how domain-driven patterns such as the domain model, the anti-corruption layer, and the open host service can help us to build maintainable microservices. We also discussed how we should expect failure and how we could use simple patterns such as retryable HTTP calls to make our system resilient to these failures.
In the next (and final) chapter, we are going to dig deeper into distributed systems and explore some more advanced DDD patterns that we can use to make our system simpler to reason about, easier to maintain, and—perhaps most importantly—easy to add new functionality to.
