Tracing requests inside microservices
Inside any application, a request may flow through several components before a final response for the request is generated. All of these components may do some processing that might be required on the process before they hand the request off to another component.
The tracing of a request allows us to visualize a rich amount of detail about the flow of a particular request. With the complete picture of the flow of the request, we can now work on finding out the places that may be causing a bottleneck in the performance of the request-response cycle, or figure out the components that may be causing the generation of an incorrect result.
Today, in the application development world, any serious application that runs on a large scale has one or another kind of tracing solution implemented into it so as to trace the flow of the requests inside the application. Currently, there are a huge number of tools and services that allow for enabling tracing inside the...
