Migrate to the NMstate provider for network configuration modernization.

Integrate certified partner content

Integrate and deploy certified third-party storage, network, and infrastructure solutions from Red Hat technology partners.

Configure optional control plane service

Enable and configure optional control plane services such as compute cells, notifications, Dashboard, and Orchestration services.

Create and manage node sets

Define and manage data plane node sets with custom services, and configurations for specialized workloads.

Configure Compute nodes and instance provisioning

Configure CPU, memory, storage, and scheduling on Compute nodes to optimize instance provisioning and performance.

Configure networking services

Set up networking services such as OVN gateways, networker nodes, network isolation, and bandwidth management with QoS policies.

Configure storage services

Configure block, image and object storage, as well as shared file systems to meet your data management requirements.

Harden the deployment

Apply security hardening best practices to protect your cloud infrastructure from vulnerabilities and unauthorized access.

Configure authentication and identity

Set up user authentication, project authorization, and identity management with external identity providers and RBAC policies.

Configure bare metal as a service

Deploy and manage physical servers as bare-metal instances using the Bare Metal Provisioning service (ironic) with tenant-defined networking.

Configure DNS as a service

Set up the DNS service (designate) to provide automated domain name management and integration with the Networking service.

Configure load balancing as a service

Deploy and manage load balancers using Octavia with support for HTTP, HTTPS, TCP, UDP protocols, and Layer 7 traffic routing policies.

Configure GPU workloads

Enable GPU support for compute instances to run AI, machine learning, and graphics-intensive workloads with GPU passthrough or vGPU.

Configure the dashboard

Customize and deploy the OpenStack Dashboard (horizon) with custom themes to provide a web-based management interface.

Configure high availability for instances

Set up automatic instance recovery and evacuation from failed Compute nodes to ensure workload continuity.

Validate the deployment

Use the OpenStack Integration Test Suite (tempest) to validate your cloud deployment and verify service functionality.

Create and manage instances

Create, configure, and manage instances in your cloud environment, including provisioning, network attachments, and storage management.

Manage persistent storage

Manage block storage volumes, virtual machine images, object storage containers, and shared file systems for your cloud workloads.

Manage project networks

Create and configure project networks, subnets, routers, floating IP addresses, and network security policies for tenant isolation.

Maintain data plane nodes

Scale, replace, or reboot data plane nodes to maintain a healthy infrastructure for compute and storage workloads.

Maintain the cloud infrastructure
