Kubernetes集群的物理部署模式解析

1. 单机房部署（单可用区）

graph TB
    subgraph 机房A
        LB[负载均衡器] --> M1[Master1]
        LB --> M2[Master2]
        LB --> M3[Master3]
        M1 --> W1[Worker1]
        M2 --> W2[Worker2]
        M3 --> W3[Worker3]
    end

2. 跨机架部署（单机房多机架）

graph TB
    subgraph 机房A
        subgraph 机架1
            M1[Master1]
            W1[Worker1]
        end
        subgraph 机架2
            M2[Master2]
            W2[Worker2]
        end
        subgraph 机架3
            M3[Master3]
            W3[Worker3]
        end
        LB[负载均衡器] --> M1
        LB --> M2
        LB --> M3
    end

3. 多可用区部署（同城多机房）

graph TB
    subgraph 可用区A
        M1[Master1]
        W1[Worker1-3]
    end
    subgraph 可用区B
        M2[Master2]
        W2[Worker4-6]
    end
    subgraph 可用区C
        M3[Master3]
        W3[Worker7-9]
    end
    GLB[全局负载均衡] --> M1
    GLB --> M2
    GLB --> M3

4. 异地多活部署（跨地域）

graph TB
    subgraph 地域A
        subgraph AZ1
            M1[Master1]
        end
        subgraph AZ2
            M2[Master2]
        end
    end
    subgraph 地域B
        subgraph AZ1
            M3[Master3]
        end
    end
    DNS[全局DNS] --> LB1[地域A LB]
    DNS --> LB2[地域B LB]

2. API Server负载均衡

graph LR
    Client --> GLB[全局LB]
    GLB --> NLB1[地域A NLB]
    GLB --> NLB2[地域B NLB]
    NLB1 --> HAProxy1
    NLB1 --> HAProxy2
    HAProxy1 --> API1[API Server1]
    HAProxy1 --> API2[API Server2]

2. 混合云场景下的网络拓扑

graph TB
    subgraph 公有云A
        M1[Master1]
        W1[Worker]
    end
    subgraph 私有云B
        M2[Master2]
        W2[Worker]
    end
    subgraph 边缘站点
        W3[Worker]
    end
    M1 -- VPC Peering --> M2
    M2 -- SD - WAN --> W3

Kubernetes部署方式：云服务与自建集群的深度对比

1. 选择云服务的条件

graph TD
    A[业务需求] --> B{是否需要快速上线?}
    B -->|是| C[选择云服务]
    A --> D{是否全球分布?}
    D -->|是| C
    A --> E{团队K8s经验?}
    E -->|缺乏| C
    A --> F{预算灵活性?}
    F -->|按需付费| C

2. 选择自建的条件

graph TD
    A[技术需求] --> B{需要定制化组件?}
    B -->|是| C[选择自建]
    A --> D{数据合规要求?}
    D -->|敏感数据| C
    A --> E{长期稳定负载?}
    E -->|是| C
    A --> F{已有运维团队?}
    F -->|成熟团队| C
