Structured Logging: Logs as Data, Not Strings
Treat logs as structured data (like JSON), not just plain text. This makes them machine-readable and queryable, letting you filter, search, and create dashboards on specific fields (e.g., `user_id`, `trace_id`).
Service Mesh: The Network Layer for Your Microservices
A service mesh acts as a dedicated network layer for microservices, handling complex communication logic outside your application. It enables features like mTLS and canary releases.
Data Lineage: The Story of Your Data
Data lineage is a family tree for your data, showing its origins, transformations, and final destination. It's essential for debugging broken analytics and tracing errors to their source.
