OpenStack

OpenStack: sixteen components, one platform.

Each OpenStack component is contracted separately, so you pay for what you run: from a minimal compute cloud to bare metal, DNS and load balancing. All of them share one platform that we deploy once for the whole environment.

One platform underneath

  • Control services run redundantly on at least three controller servers; compute and storage nodes scale to your specification
  • Every API is published through a proxy with TLS termination
  • Monitoring with Prometheus, Alertmanager and Grafana; central logging with Fluentd and OpenSearch, or Loki or the ELK stack if you prefer

Your own build of the source

OpenStack is deployed from a dedicated container registry. A dedicated git repository holds the source; we test each new upstream release, merge your patches forward and push fixes upstream. Nothing proprietary sits between you and the project, and a new major version is deployed at least once a year.

Software we operate

The sixteen components

Dependencies between them are set out in the catalogue. Keystone is the base of all the others, Nova needs Placement, Neutron and Glance, and Ceph is the default storage backend for Cinder, Glance and Gnocchi.

Service Catalogue version 4.6, effective 1 July 2026.

  1. 01 Nova Managed OpenStack Nova

    Compute: virtual servers on KVM, migration, resize, console

  2. 02 Neutron Managed OpenStack Neutron

    Networking: virtual networks, routers, floating IPs, security groups; OVN by default

  3. 03 Cinder Managed OpenStack Cinder

    Block storage: volumes, snapshots and backups; Ceph RBD by default

  4. 04 Glance Managed OpenStack Glance

    Images: registry and storage of virtual server disk images

  5. 05 Keystone Managed OpenStack Keystone

    Identity: authentication, RBAC, federation with LDAP, Active Directory and OpenID Connect

  6. 06 Horizon Managed OpenStack Horizon

    Dashboard: self-service web interface for every deployed service

  7. 07 Heat Managed OpenStack Heat

    Orchestration: declarative stacks from HOT templates, autoscaling

  8. 08 Octavia Managed OpenStack Octavia

    Load balancer as a service: L4 and L7, TLS termination; Amphora or OVN

  9. 09 Designate Managed OpenStack Designate

    DNS as a service: zones and records on BIND 9 or PowerDNS

  10. 10 Barbican Managed OpenStack Barbican

    Key manager: secrets, keys and certificates; HSM optional

  11. 11 Placement Managed OpenStack Placement

    Resource inventory and allocation for the scheduler

  12. 12 Ceilometer Managed OpenStack Ceilometer

    Telemetry: metrics and events for billing and capacity planning

  13. 13 Gnocchi Managed OpenStack Gnocchi

    Time-series database for telemetry, with archive policies

  14. 14 Masakari Managed OpenStack Masakari

    Instance high availability: automatic evacuation on node failure

  15. 15 Swift Managed OpenStack Swift

    Object storage with Swift and S3 APIs; replication or erasure coding

  16. 16 Ironic Managed OpenStack Ironic

    Bare metal: physical servers provisioned as instances over Redfish and IPMI

And Ceph beside it

Ceph is a separate platform with no dependency on OpenStack: block (RBD), object (S3 and Swift) and file (CephFS) storage on commodity servers, deployed by cephadm and made redundant by replication or erasure coding. It also serves persistent volumes to Kubernetes through Ceph CSI.

Same terms, same service levels

OpenStack is set up or taken over, accepted and operated under the same terms and response times as every other platform we operate.
