The technology behind the platform
THE COMPONENTS
What the platform is built from
Five components, all open source, all replaceable. Click through them.
OpenStack with a standard API in every environment
OpenStack provides the API, scheduler and orchestration, with state and metadata in MariaDB. The standard API means anything that speaks OpenStack works without modification: Terraform, Ansible and your existing tooling.
Stateless nodes, reinstalled on reboot
The compute nodes run a read-only OS and are provisioned over PXE. A reboot is a reinstallation: no configuration drift, no local state to lose, and a minimal attack surface on the individual node. Faults are handled by replacement, not troubleshooting.
Distributed Ceph with an S3 layer on top
VM disks and data sit in distributed Ceph storage, replicated across nodes by default. MinIO provides the S3-compatible object layer, so existing S3 integrations work without code changes.
Distributed routing on a closed optical network
EVPN/BGP distributes routing without central points of failure, and transport runs over dark fibre between locations, bypassing the internet. The full network architecture is described on the Cloud Connect page.
Two independent ways into the platform
Skyline is the primary portal and Horizon the secondary, and on top sits Edora’s own management layer with multi-region visibility and local autonomy. There is always a way in, even when one portal is unavailable.
PRINCIPLES
Four choices that explain the rest
No closed layers
Every component is open source. An exit is always technically real, and that also disciplines Edora as a supplier: the platform has to be good enough that you stay by choice.
Stateless by design
Compute nodes carry no state. Replacement instead of troubleshooting, no maintenance windows at node level, and a read-only OS as a security property.
API-first
The portal uses the same APIs as your automation. There is no function that can only be reached by clicking, and therefore no manual process that cannot be automated away.
Local autonomy
Each location routes and operates independently and survives loss of connectivity to the others. Failover is measured in seconds.
