Observability is an application state that gives you both the insight you need to understand what went wrong, and the tracing and tracking capabilities that help you understand why an error occurred.

In any application, high observability is a prerequisite for high availability. And to achieve observability in serverless applications, it’s important to get a complete picture — not just the snapshots of a single function call that most providers focus on.

This article explores the issue of observability and how a serverless environment complicates it. We then tour the native and third-party serverless observability tools and describe the journey toward ultimate observability.
