Production Go Service Essentials - Elliot Williams

Effective Go service development essentials: learn how to create high-quality services with clear documentation, trunk-based development, and observability, and discover the best practices for error handling, metrics, and logging.

Key takeaways
  • Effective documentation: Provide clear documentation of your service, including the codebase, configurations, and dependencies.
  • Trunk-based development: Merge small, incremental changes to the main branch, reducing the need for complex testing and debugging.
  • Metrics and logging: Log metrics and events, and use logging tools like Logress for structured logging.
  • Service design: Design services as stateless, decoupled processes with clear interfaces.
  • Observability: Use monitoring tools like ELK to track application performance and troubleshoot issues.
  • Error handling: Handle errors and panics in a structured way, with clear logs and metrics.
  • CI/CD: Use continuous integration and deployment to automate testing, building, and deployment.
  • Dependency management: Manage dependencies using tools like Go Modules.
  • Code quality: Write clean, testable code with a focus on maintainability.
  • Application readiness: Ensure applications are production-ready before deploying to production.
  • Infrastructure management: Use tools like Kubernetes to manage infrastructure, and orchestrate application deployment and scaling.
  • Alerting and incident management: Set up alerting and incident management processes for critical services.
  • Code reviews: Perform regular code reviews to ensure high-quality code and identify potential issues.
