Multi-Cloud Patterns

多云架构模式

Pattern 1: Single Provider with DR

模式1:单提供商搭配灾难恢复(DR)

  • Primary workload in one cloud
  • Disaster recovery in another
  • Database replication across clouds
  • Automated failover
  • 主工作负载部署在一个云中
  • 灾难恢复部署在另一个云中
  • 跨云数据库复制
  • 自动化故障转移

Pattern 2: Best-of-Breed

模式2:精选最优服务

  • Use best service from each provider
  • AI/ML on GCP
  • Enterprise apps on Azure
  • General compute on AWS
  • 选用各提供商的最佳服务
  • 在GCP上运行AI/ML
  • 在Azure上运行企业应用
  • 在AWS上运行通用计算

Pattern 3: Geographic Distribution

模式3:地理分布式部署

  • Serve users from nearest cloud region
  • Data sovereignty compliance
  • Global load balancing
  • Regional failover
  • 从最近的云区域为用户提供服务
  • 符合数据主权合规要求
  • 全局负载均衡
  • 区域故障转移

Pattern 4: Cloud-Agnostic Abstraction

模式4:云无关抽象层

  • Kubernetes for compute
  • PostgreSQL for database
  • S3-compatible storage (MinIO)
  • Open source tools
  • 使用Kubernetes进行计算管理
  • 使用PostgreSQL作为数据库
  • 兼容S3的存储(MinIO)
  • 开源工具

Cloud-Agnostic Architecture

云无关架构

Use Cloud-Native Alternatives

使用云原生替代方案

  • Compute: Kubernetes (EKS/AKS/GKE)
  • Database: PostgreSQL/MySQL (RDS/SQL Database/Cloud SQL)
  • Message Queue: Apache Kafka (MSK/Event Hubs/Confluent)
  • Cache: Redis (ElastiCache/Azure Cache/Memorystore)
  • Object Storage: S3-compatible API
  • Monitoring: Prometheus/Grafana
  • Service Mesh: Istio/Linkerd
  • 计算: Kubernetes (EKS/AKS/GKE)
  • 数据库: PostgreSQL/MySQL (RDS/SQL Database/Cloud SQL)
  • 消息队列: Apache Kafka (MSK/Event Hubs/Confluent)
  • 缓存: Redis (ElastiCache/Azure Cache/Memorystore)
  • 对象存储: 兼容S3的API
  • 监控: Prometheus/Grafana
  • 服务网格: Istio/Linkerd

Cost Comparison

成本对比

Compute Pricing Factors

计算定价因素

  • AWS: On-demand, Reserved, Spot, Savings Plans
  • Azure: Pay-as-you-go, Reserved, Spot
  • GCP: On-demand, Committed use, Preemptible
  • AWS: 按需付费、预留实例、竞价实例、节省计划
  • Azure: 按需付费、预留实例、竞价实例
  • GCP: 按需付费、承诺使用、抢占式实例

Cost Optimization Strategies

成本优化策略

  1. Use reserved/committed capacity (30-70% savings)
  2. Leverage spot/preemptible instances
  3. Right-size resources
  4. Use serverless for variable workloads
  5. Optimize data transfer costs
  6. Implement lifecycle policies
  7. Use cost allocation tags
  8. Monitor with cloud cost tools
Reference: See
references/multi-cloud-patterns.md
  1. 使用预留/承诺容量(节省30-70%成本)
  2. 利用竞价/抢占式实例
  3. 合理调整资源规格
  4. 为可变工作负载使用无服务器服务
  5. 优化数据传输成本
  6. 实施生命周期策略
  7. 使用成本分配标签
  8. 借助云成本工具进行监控
