Week 12: user journey workflow, frame pointers, spring observability, backoff

• User Journeys vs. User Flows: User journeys capture steps a user takes to reach a goal at a fairly high level. User flows are tactical and specific.
• The Return of the Frame Pointers: Low overhead profilers are an important tool for people looking to better understand how their code is running in production.
• Simplifying Spring Observability with OpenTelemetry Auto-Instrumentation and Java Agent: Using otel with a springbook app.
• What is Backoff For?: Backoff and retries are helpful in certain contexts but not necessarily all to reduce applied work to a system during overload. There are other complementary strategies to consider including retries, jitters and no doubt other things.
