ABB Cluster Management

Summary

Cluster Management is the product-neutral architecture building block for central lifecycle and policy management for platform clusters. It states what DC 3.0 needs from this capability before a concrete SBB, product, or operating model is selected.

Capabilities

  • Provides central lifecycle and policy management for platform clusters.
  • Defines the functional, technical, security, and quality expectations that SBBs must satisfy.
  • Keeps service ownership, interfaces, and consumption boundaries visible before product selection.
  • Enables traceability from architecture intent to implementation, operational evidence, and consuming services.

Constraints

  • The resulting SBB must fit the datacenters ownership model and document the support, lifecycle, and service-management boundary.
  • Security, privacy, logging, evidence, and compliance controls must be explicit enough to assess BIO2-aligned implementation where applicable.
  • Cluster state must remain declarative and auditable.
  • Policy compliance must be visible across all managed clusters.

Service Description

This ABB offers a cluster-management service for deploying, upgrading, configuring, and governing DC 3.0 clusters. It is consumed by solution architects, platform teams, and service owners as the capability contract for selecting and shaping SBBs.

The service description remains implementation-neutral: product selection, hosting pattern, detailed runbooks, and service levels belong in the mapped SBB and related ADRs.

Roadmaps

  • Baseline: confirm scope, service ownership, constraints, and acceptance criteria for Cluster Management.
  • MVP: validate the mapped SBB implementation and record the selected support and lifecycle model.
  • Next: add measurable service levels, evidence requirements, and roadmap dependencies once the SBB is selected.

Landing Zones

  • Private cloud and central DC 3.0 landing zone for core infrastructure and platform services.
  • Government cloud or external cloud landing zones only when the SBB documents the required control set, connectivity model, and data classification fit.

Interfaces

  • Cluster lifecycle APIs.
  • Policy, inventory, and compliance APIs.
  • Identity and automation interfaces for controlled operations.

Dependencies

  • Depends on clusters-as-a-service for a supporting capability or integration boundary.
  • Depends on automation for a supporting capability or integration boundary.
  • Depends on federated-authentication for a supporting capability or integration boundary.
  • Implemented by red-hat-advanced-cluster-management as currently mapped SBB traceability.
  • Consuming ABB and SBB dependencies must be recorded as links when solution design identifies concrete upstream or downstream use.

EIRA Alignment

Available SBB's

  • red-hat-advanced-cluster-management - Red Hat Advanced Cluster Management is a candidate solution building block for the translated DC 3.0 ABB model. It remains candidate until the responsible architects confirm service ownership, support model, and acceptance criteria.
