Session
Migrating from a traditional ingress controller to a service mesh-based solution in a live environment with thousands of internal users presents significant challenges. In this session, we share Bloomberg's experience transitioning from NGINX to Istio as the ingress layer for our internal private cloud platform—a managed service supporting application deployments across the firm. We explore the motivations behind this shift, the architectural and operational changes implemented, and the hurdles encountered during the migration process.
Our journey offers practical insights into planning and executing such a migration with minimal disruption, while also highlighting the new capabilities unlocked through Istio. Attendees will benefit from our lessons learned, best practices, and retrospective advice aimed at helping other engineering teams undertake similar transitions with greater confidence and fewer surprises.
