Resilience is the capability of an application or service to resist different error scenarios. Especially for distributed systems - where a lot of communication between different services happen - it's very important to explicitly think of implementing resilience.

* Do not hide API calls or any other external communication in your application (for example with unnecessary abstraction) - instead make it explicit that an external communication happens - e.g. by using the Facade Pattern. On the one hand, this makes it obvious that a potential slow and error prone communication is going to happen, and it makes it easier to implement error handling.
* Detect errors explicitly: Check the response message format and configure proper timeouts for external communication
* Handle errors in a smart way: Show a nice error message to your customer or, even better, graceful degrade features - e.g. by showing some fallback text
* Use Message-based communication where useful ([Decoupling Infrastructure via Messaging](/methods-and-patterns/decoupling-infrastructure-via-messaging/))
* Use Message-based communication where useful ([Decoupling via Messaging](/methods-and-patterns/decoupling-via-messaging/))
* Use Circuit Breaker to Isolate errors and allow system to recover
* Use short activation paths in your strategic architecture - so that there is only a minimal set of communications between your services required for certain features or business requests
"Embrace Errors" should be the mindset - because it is not a question if errors appear - it's just a question of when.
