X-Ray is AWS’s distributed tracing system. What the hell is a distributed tracing system? That means that you can trace requests as they travel through your architecture. By John T Earl.
When working in a micro-service world distributed tracing is a powerful tool that allows developers, operations, architects, and managers to see the big picture view of the application.
The author then quickly goes over:
- How does AWS X-Ray work?
- Service Map
- When do I use AWS X-Ray?
- X-Ray language support
X-ray uses an SDK and a daemon/agent. To use X-Ray you’ll need to integrate with the SDK and install the X-Ray agent then you’re good to go. X-Ray will receive data from services in segments. It groups any common segments together into something called traces.
AWS X-Ray is an invaluable tool for micro-services. If you’re working in a micro-service architecture and haven’t enabled X-Ray give it a try. Enabling X-Ray is simple and the service map it provides is great if you’re a visual learner. Like all AWS services, it’s cheap to use.
