What does it take to build observability in a web-scale company such as Slack, Pinterest and Twitter? On this episode of OpenObsevability Talks I'll host Suman Karumuri to hear how he built these systems from the ground up on these #BigTech co's, about his recent research papers and more. Suman Karumuri is a Sr. Staff Software Engineer and the tech lead for Observability at Slack. Suman Karumuri is an expert in distributed tracing and was a tech lead of Zipkin and a co-author of OpenTracing standard, a Linux Foundation project via the CNCF. Previously, Suman Karumuri has spent several years building and operating petabyte scale log search, distributed tracing and metrics systems at Pinterest, Twitter and Amazon.  In his spare time, he enjoys board games, hiking and playing with his kids.
