Cloud Platform Selection and Rationale​

Decision: [Platform Name]​

Record the chosen cloud provider and the primary reasons it was selected (cost, team familiarity, feature fit, compliance).

Deployment Architecture​

Compute Resources​

[Describe the compute model, instance sizes or autoscaling parameters, and how the application is packaged.]

Database and Storage​

[Describe the managed database service, storage classes for object storage, and retention behavior.]

Networking​

[Describe the network topology: VPC/subnets, ingress path, and any load balancing.]

Scaling Strategy​

DimensionStrategyLimits / Constraints
Compute[horizontal / vertical][max instances, cost ceiling]
Database[read replicas / vertical][max size]

High Availability and Failover​

  • [How the system remains available during a single-node failure.]
  • [Failover behavior for the database layer.]

Backup and Disaster Recovery​

ResourceBackup MethodRPORTORecovery Runbook
Database[daily snapshot + WAL / point-in-time][e.g. 5 min][e.g. 15 min][link to runbook]
Object Storage[platform default + versioning][24h][1h][link]

RPO = acceptable data loss window; RTO = acceptable downtime window.

Cost Optimization Strategy​

  • [e.g. use free-tier-eligible services for MVP.]
  • [e.g. review spend monthly; set billing alerts.]
  • [e.g. downsize or sleep non-production resources.]

Infrastructure as Code (IaC) Approach​

  • Tool: [Terraform / Pulumi / CDK / —]
  • State management: [remote backend, locking]
  • Workflow: plan on PR, apply on tag/deploy
  • [Link the IaC ADR once created.]

Security Architecture Considerations​

  • Secrets are injected at runtime; never stored in code or images (see Security Architecture).
  • [Network isolation rules, if any.]
  • [Compliance considerations.]

Deployment Impact Summary​

  • [Key constraints this architecture imposes on the CI/CD pipeline.]
  • [What must happen (or not happen) during deployment.]
