What-If Simulation
Definition
What-If Simulation 是 Agentic AI 模拟架构变更（如云迁移、实例类型变更）对性能、成本和合规的影响，支持数据驱动的决策。
应用场景
| 场景 | 模拟内容 | 决策支持 |
|---|---|---|
| 云迁移 | AWS → GCP 迁移影响 | 性能/成本/合规权衡 |
| 实例变更 | m5.xlarge → m5.large | 性能影响评估 |
| 架构重构 | 单体 → 微服务 | 复杂度/收益分析 |
| 多云策略 | 工作负载分配 | 成本优化建议 |
Agentic AI What-If Simulation 工作流
1. Define Scenario → "Moving from AWS EKS to GCP GKE"
2. Gather Baseline → 当前性能/成本/合规指标
3. Model Impact → AI 基于历史数据和预测模型
4. Generate Report → 性能差异/成本差异/风险评估
5. Recommend → 最优方案 + 实施路径
示例
An AI agent simulates moving an AWS-based SaaS application to GCP's Private Cloud in KSA (Saudi Arabia):
Performance Impact:
- Latency: +45ms (KSA → GCP EU)
- Availability: 99.9% → 99.95% (enhanced SLA)
Cost Impact:
- Compute: -20% (GCP preemptible pricing)
- Egress: +15% (cross-region data transfer)
- Net: -12% annual savings
Compliance Impact:
- Data Sovereignty: ✅ KSA data residency satisfied
- SLA: ✅ GCP private cloud meets enterprise agreement
Recommendation: Proceed with migration, implement CDN for latency optimization
