在Google：microservices become API Apigee API Management complements Istio with the robust features of Google Cloud's Apigee API management platform, Apigee Edge, by extending API management natively into the microservices

Why Service Mesh? ● Current challenges include - ○ Manageability of Hardware Devices ■ Traffic Management & Security Enforcement ■ Updating hardware devices is slow ○ Achieving micro-segmentation at Discovery functions as features of the infrastructure - ○ Functions: TLS Termination, Traffic Management, Tracing, Rate Limiting, Protocol Adapter, Circuit breaker, Caching, etc. #IstioCon Service Architecture Evolving Security Current Status #IstioCon Step 1: Access Point Spec ● Capture Traffic Management & Routing intent as “Access Point” Specs ○ Leverage Istio object model: Gateway, VirtualService

complexity ○ Need consistent policy enforcement ○ Need consistent metrics aggregation ● Traffic management ○ Load balancing for VMs, failover, A/B testing, modern rollouts for VM services ● Security workload certificate attributes #IstioCon Security & Usability Limitations (cont.) ● Access management: CNI needs improvements ○ Much required to avoid escalated Pod privileges ○ No support for smart Sidecar Offload ● Ultimate goal ○ Proxyless services (for high performance) ● Offload ○ Traffic management ○ Security (DDoS defense…) ● HW acceleration ○ Crypto ○ Rule matching ● Further isolation
