How we choose a metrics solution for our hybrid cloud platform and how we scale it. As enterprises grow, observability platforms must keep pace with increasing data volumes, stricter reliability requirements, and the need for faster insights. At Deutsche Bank, these challenges became especially critical within the IB (Investment Banking) Hybrid Cloud platform, where one monitoring environment needed to be migrated and optimized without disruption. The talk will walk through the migration process, technical decisions, and lessons learned, highlighting both the benefits and challenges encountered along the way. It will cover practical strategies for seamless migration between monitoring systems and best practices for running VictoriaMetrics at scale.
