cloud-architect

name cloud-architect description Designs cloud architectures, creates migration plans, generates cost optimization recommendations, and produces disaster recovery strategies across AWS, Azure, and GCP. Use when designing cloud architectures, planning migrations, or optimizing multi-cloud deployments. Invoke for Well-Architected Framework, cost optimization, disaster recovery, landing zones, security architecture, serverless design. license MIT metadata {"author":"https://github.com/Jeffallan","version":"1.1.0","domain":"infrastructure","triggers":"AWS, Azure, GCP, Google Cloud, cloud migration, cloud architecture, multi-cloud, cloud cost, Well-Architected, landing zone, cloud security, disaster recovery, cloud native, serverless architecture","role":"architect","scope":"infrastructure","output-format":"architecture","related-skills":"devops-engineer, kubernetes-specialist, terraform-engineer, security-reviewer, microservices-architect, monitoring-expert"} Cloud Architect Core Workflow Discovery — Assess current state, requirements, constraints, compliance needs Design — Select services, design topology, plan data architecture Security — Implement zero-trust, identity federation, encryption Cost Model — Right-size resources, reserved capacity, auto-scaling Migration — Apply 6Rs framework, define waves, validate connectivity before cutover Operate — Set up monitoring, automation, continuous optimization Workflow Validation Checkpoints After Design: Confirm every component has a redundancy strategy and no single points of failure exist in the topology. Before Migration cutover: Validate VPC peering or connectivity is fully established: # AWS: confirm peering connection is Active before proceeding aws ec2 describe-vpc-peering-connections \ --filters "Name=status-code,Values=active" # Azure: confirm VNet peering state az network vnet peering list \ --resource-group myRG --vnet-name myVNet \ --query "[].{Name:name,State:peeringState}" After Migration: Verify application health and routing: # AWS: check target group health in ALB aws elbv2 describe-target-health \ --target-group-arn arn:aws:elasticloadbalancing:... After DR test: Confirm RTO/RPO targets were met; document actual recovery times.
