Deployment Types
Ironcore can be deployed in two common models. Both use the same platform services and OpenStack-compatible APIs; the difference is how those services are placed and protected.All-in-One
A compact deployment where controller, compute, storage, networking, dashboard, and
supporting services run on a single node. This is best for labs, demos, proofs of
concept, edge sites, and small environments where simplicity matters more than
service-level redundancy.
Multinode High Availability
A production deployment spread across multiple controller, compute, storage, and
network nodes. Control-plane services run in HA, workloads can be distributed across
compute hosts, and the platform can tolerate planned maintenance or node failures.
Requirements at a Glance
| Model | Typical Requirement | Best For |
|---|---|---|
| All-in-One | One capable server with CPU virtualization enabled, enough memory, local or attached storage, and network access for tenant and management traffic | Evaluation, demo, small private cloud, branch or edge use cases |
| Multinode High Availability | Multiple servers with separate roles for controllers, compute, storage, and networking; redundant management and tenant networks; shared or distributed storage; planned IPs and DNS | Production private cloud, enterprise workloads, service-provider environments |
How HA Works
In a multinode deployment, Ironcore runs key platform services in redundant mode. API services, identity, dashboard, networking control services, databases, message queues, monitoring, and load-balanced endpoints are deployed across controller nodes. Compute workloads run across multiple hypervisor nodes, and storage can use distributed backends so data remains available even when individual nodes need maintenance.Choose All-in-One when you want the fastest path to a working environment. Choose
Multinode High Availability when uptime, scale, maintenance windows, and production
resiliency matter.
