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
