MicroCloud

MicroCloud creates a lightweight cluster of machines that operates as a scalable private cloud. It combines LXD for virtualization, MicroCeph for distributed storage, and MicroOVN for networking—all automatically configured by the MicroCloud snap for reproducible, scalable deployments.

With MicroCloud, you can eliminate the complexity of manual setup and quickly benefit from high availability, streamlined security updates, and fine-grained access control for multi-tenancy. Cluster members can run full virtual machines or lightweight system containers with bare-metal performance. Manage it through your choice of client interfaces, including a graphical UI and CLI.

MicroCloud is designed for small-scale private clouds and hybrid cloud extensions. Its efficiency and simplicity also make it an excellent choice for edge computing, test labs, and other resource-constrained use cases.

MicroCloud supports single-node deployments, but at least 3 nodes are recommended for high availability.

Once the simple bootstrapping is completed, users can launch, run and manage their workloads, and otherwise utilize regular LXD functionalities.

To get started, LXD, MicroCeph, MicroOVN and MicroCloud snaps are needed. Users can install them at once with the command:

snap install lxd microceph microcloud microovn

The bootstrapping process starts with running

microcloud init on the initiating member
and microcloud join on the joining members if you're using more than one system.

Following the simple CLI prompts, a working MicroCloud will be ready within minutes.
