Managing microservices at scale isn’t just about deploying more services—it’s about making them communicate securely, efficiently, and reliably. That’s where Service Mesh comes in. In this episode of Tech Radar Voice, Haggai Philip Zagury, DevOps Architect & Tech Lead at Tikal, sits down with Uri Brodsky, Senior Engineering Manager & Head of Backend Guild at Riskified, to break down how Istio and Envoy help teams manage traffic, security, observability, and scaling across multi-cloud environments. They discuss Riskified’s journey to Service Mesh, the challenges of securing thousands of microservices, and how Istio enables mTLS, progressive deployments, and improved developer experience without requiring changes at the application level. From streamlining service-to-service communication to supporting dynamic environments and canary releases, this episode offers hands-on insights for teams navigating cloud-native architectures.
