When Connections are Magic: Understanding Performance in Serverless - James Burns, LightStep

Sign up or log in to save this to your schedule and see who's attending!

While understanding API performance in serverless environments at major cloud providers we saw that runtimes may modify HTTP request behavior providing ""pre-connected"" clients leading to significant performance differences – as much as 4x in some cases. Integrating information from net/http/httptrace in Go into distributed traces lead to invaluable insights into how and why connections (and hence entire transactions) performed differently in many environments.

Working with many modern systems means network connections, many of them. Understanding how those connections impact your customer's experience can be difficult. Distributed tracing helps isolate what parts of the system are failing, but when only implemented at the RPC level the reasons for and scope of network induced issues can be lost. We provide specific examples and source code to get this visibility in your applications.
