SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams avoid fragile cloud setups by providing a practical blueprint for multi-cloud/VPC design, high availability, disaster recovery, and cost control so production deployments are safer and more predictable.

Core Features & Use Cases

  • Resilient VPC Architecture: Lays out multi-tier network segmentation using public/load balancer tiers and private app/database subnets, plus guidance for multi-VPC connectivity (peering/Transit Gateway).
  • High Availability by Design: Covers Multi-AZ compute patterns, database replication, durable storage, resilient DNS failover, and CDN distribution to reduce downtime and latency.
  • Disaster Recovery Planning: Compares DR strategies by RTO/RPO and provides an actionable DR plan checklist, including cross-region backups and encryption.
  • Cost Optimization Practices: Recommends right-sizing, reserved/savings plans, spot usage for fault-tolerant workloads, storage lifecycle management, and cost monitoring.

Quick Start

Use the cloud-architecture skill to generate a production-ready reference architecture by asking: "Propose a multi-tier, Multi-AZ VPC design for my application with HA and DR, recommend DR strategy by target RTO/RPO, and include cost-optimization steps—assume AWS for the baseline and note where GCP/Azure differ."

Frequently Asked Questions about cloud-architecture

FAQPage Schema
How do I design a multi-tier VPC architecture for high availability?▼

Cloud cost optimization combines right-sizing compute resources, purchasing reserved or savings plans, applying spot instances for fault-tolerant workloads, and implementing storage lifecycle management. Continuous cost monitoring ensures predictable spending as workloads scale.

How do I plan a disaster recovery strategy using RTO and RPO targets?▼

Disaster recovery planning compares backup, pilot light, warm standby, and active-active strategies against your RTO and RPO targets. Cross-region backups and database replication are recommended for lower RTOs, while active-active multi-region deployments achieve near-zero downtime.

What is the best way to connect multiple VPCs for multi-cloud resilience?▼

Multi-VPC connectivity uses peering for simple transit or Transit Gateway for hub-and-spoke routing across cloud accounts. Resilient DNS failover and CDN distribution route traffic automatically, reducing latency and downtime during regional failures.

Can I use this approach for both AWS and GCP or Azure cloud environments?▼

IAM security layering restricts access using least-privilege roles, while IaC and CI-CD pipelines automate infrastructure deployment. Runbooks and periodic failover tests validate that these security and automation layers function correctly during actual outages.

How do I implement IAM security and automation for cloud infrastructure?▼

IAM security layering restricts access using least-privilege roles, while IaC and CI-CD pipelines automate infrastructure deployment. Runbooks and periodic failover tests validate that these security and automation layers function correctly during actual outages.
