I recommend this lecture to anyone who wants to gain insight into a hot topic in the DevOps field called Observability, which is based on log analysis and inter-service correlation analysis on microservices.

A must-have for DevOps engineers.
Observability that works in practice!
1️⃣
After changing the system structure to MSA, which is the latest trend, has it become more difficult to identify and resolve the cause of errors ?
2️⃣
Are you curious about how to bring together log analysis and inter-service relationships in microservices?
3️⃣
Want to learn the theoretical foundations and practical implementation methods of Observability , one of the latest DevOps trends?
As many companies begin to adopt cloud-native and container technologies, tracking events occurring in distributed systems like microservices has become increasingly important. Observability, which demonstrates this importance, is also emerging as a hot topic in the microservice and DevOps fields. However, documentation or materials that explain how these concepts are implemented and implemented are rare.
• • •
When changing the structure of a microservice-based system, an integrated analysis solution is required that can comprehensively analyze issues such as data correlation and exceptions between systems.
OpenTelemetry provides a foundation for tracking and analyzing the correlations and events between each microservice according to the flow of request calls through the concepts of Trace ID and Span ID.
This course will teach you practical methods for applying OpenTelemetry, Log, Trace, and Metrics to applications based on Java with Spring, Node.js, and Python.
In addition, you will learn how to analyze the correlation between systems using open-source APM and analyze which part of the system you manage is causing delays.

I'm a digital nomad IT engineer with approximately 15 years of experience as a full-stack developer and DevOps engineer/consultant in Korea, Australia, and the UK. I'm constantly learning new topics to optimize IT organizational operations , and I dream of remaining an engineer until I retire. Currently, I work as a DevOps engineer on the Developer Experience team at a bank in Melbourne, Australia.
Q. You show implementation examples using three languages . What level of understanding is required for each language?
The basic microservice implementation has already been completed, but only some programming knowledge is required for implementing OpenTelemetry. Therefore, a beginner-level programming level is required, with a basic understanding of how code works.
Q. What level of understanding of Kubernetes is required?
You need to have a good understanding of kubectl commands, and since the entire process of creating a Kubernetes Template is explained along the way, you can take the course even if you have no prior knowledge of Kubernetes.
Q. Do I have to take " DevOps Essentials " and " ProjectSet #1 " to take this course?
While you'll likely understand the material better if you take those two lectures before taking this one, you can still enjoy this lecture without having to take them. If you need prior knowledge of the previous two lectures, I'll provide a summary of those lectures before proceeding.

It was an area that was absolutely necessary at the operational level, and it was incredibly helpful to show the area to be reached!! Unlike commercial APMs that are relatively very expensive, it was good to see that it can be solved with technology by combining open source APM tooling, and especially because it was a lecture that explained in Korean the combination of open sources that are currently growing in the community, it was better than expected. In particular, even if you don't use the tool directly, the explanation of how the concepts used in o11y are solved in each implementation system and UI and why filtering work must be involved was impressive. Thank you.
