Physical Architecture

Physical architecture details servers, networks, containers, databases, SaaS tenants, and geographic deployment that realize logical components. It includes capacity, redundancy, monitoring, and operational runbooks at architecture level. Physical choices must reflect security, cost, and lifecycle constraints.

In Practice

Larkinized LLC ensures physical architecture reviews include operations, security, and FinOps stakeholders—not only engineering. Reference deployment templates reduce variance across teams. Physical baselines feed migration cutover planning and disaster recovery validation.

Example

A physical architecture diagram maps microservices to Kubernetes clusters across two regions with active-passive database failover.
