You manage distributed transactions in microservices by implementing the Saga pattern with compensating actions. This approach orchestrates multi-service workflows and rolls back previous steps sequentially if a failure occurs, maintaining data consistency without two-phase commits.

To build resilience in microservices, apply the Circuit Breaker pattern for fault isolation. It monitors external calls, trips open during failures to stop cascading errors, and allows graceful degradation or retry logic until the downstream service recovers.

Apply 12-Factor App principles to microservices by externalizing configuration, treating logs as event streams, and ensuring stateless startup stability. These practices enable cloud-native services to scale horizontally and deploy consistently across environments.

You need a circuit breaker in a distributed system when external service calls may fail or timeout. It prevents cascading failures by blocking requests to an unhealthy service, giving it time to recover while your application handles the error gracefully.

No specific frameworks are required. The skill provides architecture patterns, implementation guidance, and example snippets for Saga orchestration, circuit breaker resilience, and 12-Factor practices that apply across any distributed systems technology stack.

Microservices architectures introduce transaction complexity because data spans multiple independent services. The Saga pattern solves this by replacing traditional database transactions with a sequence of local operations and compensating actions to maintain consistency.
