Mintlify Docs Micro-segmentation คืออะไร
Mintlify เป็น modern documentation platform ที่ช่วยสร้าง developer docs สวยงามจาก MDX files พร้อม API reference, code examples และ interactive components Micro-segmentation คือ network security strategy ที่แบ่ง network เป็น segments เล็กๆ เพื่อควบคุม traffic ระหว่าง workloads อย่างละเอียด การรวมสองแนวคิดนี้ช่วยให้ทีม security สร้าง documentation สำหรับ micro-segmentation policies ที่อ่านง่าย ค้นหาได้ และอัปเดตอัตโนมัติผ่าน CI/CD pipeline

## Policy Overview
Our micro-segmentation strategy uses **identity-based policies**
to control traffic between services.
<Card title="Zero Trust" icon="shield-check">
All traffic is denied by default. Only explicitly allowed
connections are permitted.

## Current Policies

**Destination:** `app=api-server`
**Port:** TCP 8080

Q: Mintlify กับ Docusaurus อันไหนดี?
A: Mintlify: สวยกว่า, AI search, API playground built-in, managed hosting Docusaurus: open source, self-hosted, customizable มากกว่า, community ใหญ่ ใช้ Mintlify: developer docs, API reference, ต้องการ quick setup ใช้ Docusaurus: open source preference, heavy customization, self-hosted
Q: Micro-segmentation ต่างจาก firewall อย่างไร?
A: Firewall: ควบคุม traffic ที่ network perimeter (North-South) Micro-segmentation: ควบคุม traffic ระหว่าง workloads ภายใน (East-West) Firewall: IP-based rules, coarse-grained Micro-segmentation: identity-based, fine-grained (per workload) ใช้ทั้งคู่: firewall สำหรับ perimeter + micro-segmentation สำหรับ internal
Q: Calico กับ Cilium อันไหนดี?
A: Calico: mature, iptables-based (or eBPF), BGP support, enterprise version Cilium: eBPF-native, L7 visibility, faster, Hubble observability ใช้ Calico: existing setup, BGP networking, enterprise support ใช้ Cilium: performance-critical, L7 policies, observability สำคัญ
Q: Documentation as Code จำเป็นไหม?
A: จำเป็นมากสำหรับ security policies Docs ที่ไม่ update = misleading = security risk Auto-generate จาก policy YAML = docs always up-to-date CI/CD pipeline = ทุก policy change ต้องมี docs review เริ่มง่ายๆ: YAML → auto-generate MDX → deploy to Mintlify
