The document discusses Istio, a service mesh solution that enhances the developer experience by streamlining the implementation of features and problem-solving through efficient service management. It outlines the benefits of using a service mesh to handle tasks like TLS security, retries, and monitoring in a centralized manner, reducing redundant efforts across microservices. The document also mentions integration with Weave Cloud for observability and monitoring, alongside its components like Envoy and Mixer.
Istio Service Mesh
- 1. Istio! Luke Marsden, Developer Experience @lmarsden
- 5. Developers Users competitiveness = speed of iteration
- 6. Service mesh • Your app normally has: • API server, needs securing with TLS • API client, needs retries • Load balancer to send traffic to the right place depending on policies • Authentication and authorization • Circuit breaking • Monitoring instrumentation (Prometheus) • …
- 7. Service mesh • Service mesh says: • Move this into a sidecar!
- 16. Benefits • Do it well once, rather than over and over again • Save effort! • Microservices are polyglot • Don’t want to have to rewrite all that logic in N different languages
- 17. Istio components • Envoy • Smart reverse proxy as shown • Mixer • “Control” service to which Envoys connect • Also: • Pilot for config, Istio-Auth for TLS...

- 19. Istio and Weave Cloud • Istio works great with Weave Cloud • Use Weave Cloud Explore to visualize Istio in action • Have Weave Cloud Monitor handle the long-term storage of Prometheus metrics • Demo…
- 20. What does Weave do? Weave helps devops iterate faster with: • observability & monitoring • continuous delivery • container networks & firewalls Weave Net provides a Kubernetes pod network & Network Policy implementation
