Service Mesh

🏛️ Anchor Pillar Hub #8: Alipay Double 11 Architecture (544K TPS) | 🗺️ Sitewide Engineering Reading Map ← Series hub ← Prev • Next → Answer-first: Alipay’s tech stack combines SOFAStack middleware, OceanBase distributed databases, and lightweight Service Mesh sidecars to achieve high-density microservice deployments with low inter-service RPC overhead. Implementing this architecture enforces sub-50ms P99 latency guarantees, zero-allocation memory pooling with Go 1.24 unique.Handle, and fault-tolerant Dapr 1.15 component orchestration for resilient production scaling. This design guarantees sub-50ms P99 latency bounds and zero-allocation memory pooling. ...

Answer-first: API Gateways govern north-south ingress traffic crossing untrusted perimeter boundaries, executing edge authentication, rate limiting, and protocol translation. Conversely, Service Meshes manage east-west internal pod-to-pod communication, enforcing mutual TLS zero-trust identity, distributed telemetry, and traffic shifting. Rather than competing alternatives, modern architectures deploy both symbiotically, with eBPF sockops bypassing kernel TCP stacks to eliminate sidecar proxy latency. Prerequisite: In-depth knowledge of OSI Layer 4/Layer 7 networking, Kubernetes Ingress and Gateway API specifications, Envoy proxy architecture, and mutual TLS fundamentals is required for this chapter. ...

📖 Series Navigation: ← Previous Chapter: Part 9 — Cookie vs. SessionStorage vs. LocalStorage | Series Hub Part 10: Envoy Gateway vs. Cilium eBPF Service Mesh: Kernel Performance & Layer 7 Governance Showdown Answer-first: Envoy Gateway excels as a North-South Edge API Gateway with dedicated Envoy pods for advanced L7 policies (WAF, JWT, rate limiting, AI token quotas). Cilium eBPF dominates East-West cluster networking by bypassing the TCP/IP stack via sockops and cutting 92% RAM with node-level Envoy daemons. The 2026 standard combines both. ...

Tech Radar Digest October 2026: Cilium 1.17, Tetragon 1.4 & eBPF Autonomous Agent Security Answer-First: The October 2026 Tech Radar establishes in-kernel eBPF as the mandatory architectural foundation for autonomous AI agent infrastructure. By pairing Cilium 1.17 sidecarless socket splicing (eliminating 15ms–35ms Envoy IPC tax with sub-1.2ms P99 latency) with Tetragon 1.4 synchronous in-kernel enforcement (SIGKILL in under 12 microseconds), platform engineering teams achieve hardware-grade zero-trust sandboxing and unassailable egress containment. ...

Tech Radar: Cilium 1.17 & Tetragon 1.4: In-Kernel eBPF Observability, Sidecarless Service Mesh & Zero-Trust Sandboxing for Autonomous AI Agents Answer-First: Deploying autonomous AI agent swarms with dynamic tool execution creates severe remote code execution exposure. Cilium 1.17 replaces high-overhead Envoy sidecars with in-kernel sockops socket splicing, reducing P99 latency by 92.3% to 1.12ms under 100K RPS. Concurrently, Tetragon 1.4 intercepts sys_enter_execve within the Linux 6.8 kernel, delivering synchronous SIGKILL termination in under 12 microseconds. ...
