architecture O3K
by Kubedo
O3K Project Technical Preview / Alpha

OpenStack-compatible infrastructure without full OpenStack operational weight.

O3K provides a lightweight, OpenStack-compatible control plane designed for early technical evaluation. Lower your operational overhead while maintaining API compatibility with familiar orchestration tools and workflows.

API INTEGRATION

Familiar OpenStack workflows

Standard OpenStack REST APIs for compute, network, storage, identity, and image management workflows.

  • check Works with standard OpenStack CLI tools
  • check Terraform provider compatibility focus
  • check Compatible API responses and models

ARCHITECTURE

Reduced control-plane complexity

A single lightweight process replaces multiple distributed OpenStack services and message brokers.

  • check No RabbitMQ or message bus required
  • check Single Go-binary micro-architecture
  • check Minimal operational infrastructure overhead
biotech
EVALUATION FIT

Designed for technical evaluation

Perfect for home labs, edge testing, and engineering teams assessing OpenStack workflows.

  • check Small, predictable footprint
  • check Focus on core API compatibility verification
  • check Rapid, scriptable deployment and teardown
Technical Snapshot

Engineered for simplicity. Compatible by design.

package

Single Go binary

Compiled control plane components run inside a single system process.

layers

Core Services

Implements core OpenStack APIs covering Compute, Network, Identity, and Image.

database

Embedded SQLite

Default embedded database for immediate startup and zero-config local runs.

storage

External PostgreSQL Option

Switch to standard PostgreSQL databases for structured lab testing.

link_off

No Broker Overhead

In-process communications replace complex broker message distributions.

extension

Workflow Validation

Prioritizes API syntax fidelity to ensure standard CLI and plugin compatibility.

Project Roadmap & Status
1
Current Phase

Technical Preview / Alpha

Initial release designed for sandboxed evaluation. We are collecting engineering feedback on core API workflows, resource footprints, and local installation stability.

2

API Coverage Expansion

Broadening OpenStack REST API syntax coverage in subsequent releases to support complex nested orchestration, tenant isolations, and standard horizon dashboard features.

3

Validation Ecosystem

Developing automated validation tests against standard client libraries to continue validating workflow behavior across standard clients and plugins.

4

Evaluation for Technical Fit

Finalizing validation and telemetry setups to allow engineering teams to assess O3K's suitability for specific edge and localized evaluation environments.

deployed_code

Evaluate O3K based on technical fit.

Explore the open-source repository, run the control plane locally, and verify the workflows. We are available to help you analyze fit and operational requirements.
