arrow_back How Appdynamics runs a Multi-tenant Kubernetes+Helm cluster with continuous deployment & monitoring
How we scaled devops while we scaled 20x at SumoLogic

SumoLogic is a unified logs and metrics platform for monitoring and troubleshooting and operational and security analytics. Ours is a cloud based microservices architecture that is multitenant in nature, analyzing upto 100+ petabytes, ingesting 100+ terabytes and serving 20+ million queries per day.
As a devops engineer in SumoLogic, we design, build, deploy, monitor our services all at the same time. To build for cloud scale in a microservices multitenant architecture that is dynamically changing and evolving, and to manage an ever-growing infrastructure, while being agile, has its unique challenges. Since our customers use SumoLogic for business critical needs, it is paramount that our service is always up and running.
So this talk is about the journey of scaling more than 20x, the engineering and operational challenges we faced and how we today run Sumo Search successfully, cost optimally and reliably while still being agile.
We will cover real case studies of what worked and what didn’t, go over our solutions and key lessons to build for scale. We will also cover how we do continuous testing and how we set up monitoring and alerting to run our services reliably.
