## Infoblox NIOS
|
||||
|
||||
Infoblox 的核心网络控制平面操作系统,提供 **DNS**、**DHCP** 和 **IP 地址管理(IPAM)** 三大核心功能。作为企业级网络基础设施,NIOS 是 Cloud Transformation Programme 中 IPAM 自动化方案的技术核心。
|
||||
|
||||
## Core Functions
|
||||
|
||||
### 1. DNS(域名系统)
|
||||
- 权威 DNS 服务器
|
||||
- DNS Anycast 支持全球低延迟解析
|
||||
- 与 Microsoft Active Directory 深度集成
|
||||
|
||||
### 2. DHCP(动态主机配置协议)
|
||||
- 自动化 IP 地址分配
|
||||
- IP 租约管理
|
||||
- 与 DNS 动态更新集成
|
||||
|
||||
### 3. IPAM(IP 地址管理)
|
||||
- 集中化 IP 地址池管理
|
||||
- 可扩展属性(Extensible Attributes)存储元数据
|
||||
- API 驱动的自动化分配
|
||||
- 与 IaC 工具(Terraform/Terragrunt)集成
|
||||
|
||||
## Extensible Attributes
|
||||
|
||||
NIOS 支持自定义可扩展属性,用于存储业务元数据:
|
||||
|
||||
| 属性名 | 用途 |
|
||||
|--------|------|
|
||||
| space_owner | IP 地址空间负责人 |
|
||||
| company | 所属公司/业务单元 |
|
||||
| subnet_name | 子网名称 |
|
||||
| compartment_type | 隔间类型 |
|
||||
| status | 分配状态(allocated/reserved/available) |
|
||||
| business_contact | 业务联系人 |
|
||||
| engineering_contact | 工程联系人 |
|
||||
|
||||
## Architecture
|
||||
|
||||
- **Grid Master**:主控节点,位于休斯顿数据中心
|
||||
- **冗余服务**:DNS、NTP、DHCP 多活冗余
|
||||
- **API 接口**:RESTful API 支持自动化集成
|
||||
- **与 AWS 集成**:通过 VPC 供给流水线调用 NIOS API 分配 IP 地址
|
||||
|
||||
## Key Concepts
|
||||
|
||||
- [[IPAM]]:NIOS 的核心功能之一
|
||||
- [[Infoblox-Grid]]:NIOS 的分布式网格架构
|
||||
- [[DNS-Anycast]]:NIOS 的 DNS 高可用机制
|
||||
