You now understand cloud platforms at the level expected in SRE interviews.
What to remember:
- AWS: EC2 for VMs, EKS for Kubernetes, S3 for objects, CloudWatch for observability
- GCP: GKE is strong for Kubernetes, global VPCs simplify networking, Cloud Operations for monitoring
- VPC design: Public subnets for internet-facing, private for internal, plan CIDR carefully
- Cost optimization: Right-size, use reserved/spot, auto-scale, tag everything
- Multi-cloud adds complexity. Use only when requirements demand it
You've completed Phase . Next phases cover observability, reliability practices, and interview execution.
