- One of the primary challenges with microservices architectures is allowing services to discover and interact with each other.
- The distributed characteristics of microservices architectures not only make it harder for services to communicate, but also presents other challenges, such as checking the health of those systems and announcing when new applications become available.
- You also must decide how and where to store meta-store information, such as configuration data, that can be used by applications.
