references/service-comparison.mdMulti-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

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
