The rapid growth of the CloudStats user base and the number of services being monitored created a significant load on its MySQL infrastructure. The system ingests large amounts of incoming metrics/event data collected by thousands of agents. The backend systems also perform analytics on large portions of that data, and alerts are triggered as soon as certain conditions are met.

Andrey Vasilyev, CTO of Aqua Networks Limited - a London-based company which owns brands, such as, and, and Art van Scheppingen, Senior Support Engineer at Severalnines, will discuss the challenges encountered by in achieving database high availability and performance, as well as the solutions that were implemented to overcome these challenges.
