I was inspired by OpenZipkin contributor and Spring Cloud Sleuth and Zipkin contributor Adrian Cole’s epic talk introducing Zipkin to write this particular post. There’s so much epic stuff in that talk, so once you’re done reading this, go watch that!
Advances in technology and cloud computing have made it easier to stand up and deploy services with ease. Cloud computing enables us to automate away the pain (from days or weeks (gasp!) to minutes!) associated with standing up new services. This increase in velocity in turn enables us to be more agile, to think about smaller batches of independently deployable services. The proliferation of new services complicates reasoning about system-wide and request-specific performance characteristics.
