Domain Owner: Cloud & Infrastructure Engineering
Tier: Foundational Infrastructure
The Compute domain encompasses every layer of processing capacity delivered to the organisation — from physical servers in the data centre, through hypervisors and private cloud, up to public cloud workloads and containerised microservices. It is the foundation on which all application and data services run.
| Page | Description |
|---|---|
| Server Infrastructure | Physical server standards, rack design, BIOS/firmware policy |
| Virtualisation | VMware vSphere standards, VM templates, HA/DRS policy |
| Cloud Computing | AWS & Azure landing zones, governance, cost management |
| Containers & Orchestration | Kubernetes (EKS), image standards, CI/CD integration |
All workloads are classified into one of three tiers which determine availability, RPO/RTO, and support obligations:
| Tier | Classification | Target Availability | RPO | RTO |
|---|---|---|---|---|
| 1 | Mission Critical | 99.99% | 0 min | 15 min |
| 2 | Business Important | 99.9% | 1 hr | 4 hr |
| 3 | Standard | 99.5% | 24 hr | 24 hr |
Tier assignment is determined during the Application Onboarding process and recorded in the CMDB.
