Study Notes
Red Hat Advanced Cluster Management for Kubernetes (RHACM)
- Provides comprehensive management, visibility, and control over Kubernetes clusters across diverse environments, including on-premise and multiple public clouds.
Key Benefits
- Accelerates application development through self-service provisioning and automated application deployment, reducing manual efforts and accelerating time-to-market.
- Increases application availability by deploying applications across distributed clusters quickly, supporting both traditional and modern application needs.
- Enhances security and compliance through centralized policy enforcement and automated alerts for configuration drift, enhancing overall security posture.
- Offers a unified management interface, reducing operational costs with a single control plane for managing the lifecycle of multiple clusters across various environments.
Features Overview
Multicluster Observability
- Utilizes Grafana dashboards to monitor fleet health across OpenShift and non-OpenShift clusters like EKS, GKE, AKS, and IKS.
- Supports long-term data retention for trend analysis and issue resolution.
Unified Multicluster Lifecycle Management
- Simplifies cluster creation, upgrades, and destruction using Infrastructure as Code (IaC) principles.
- Supports diverse cloud platforms including AWS, Azure, GCP, and bare metal.
Policy-Based Governance
- Implements out-of-the-box policy templates.
- Integrates with Gatekeeper and Open Policy Agent (OPA) for enforcing security, compliance, and operational best practices across clusters.
Advanced Application Lifecycle Management
- Manages application deployments with customizable placement rules.
- Integrates with CI/CD pipelines.
- Supports GitOps tools like Argo CD.
Edge Management at Scale
- Scales efficiently in edge environments with support for single-node OpenShift clusters and zero-touch provisioning.
- Ensures high availability and scalability in low-bandwidth, high-latency scenarios.
Technical Specifications
Hub Cluster Requirements
- Requires Red Hat OpenShift Container Platform 4.12 and above.
- Provides operator-based installation and management.
Managed Cluster Support
- Offers full lifecycle management for Red Hat OpenShift clusters on AWS, Azure, GCP, VMware, OpenStack, and bare metal.
- Provides additional support for legacy versions and limited support for managed Kubernetes services like EKS, AKS, IKS, and GKE.
