Canonical has launched MicroCloud 3.1, the cloud infrastructure management toolkit (the first release of the 3.x branch) that enables rapid deployment of cloud systems and computing clusters with a shared distributed data storage and secure virtual network on your hardware. MicroCloud is packaged as a snap, including the components needed to manage the operation of cluster nodes. The toolkit is written in Go and is distributed under the AGPL 3.0 license. <\/p>\n

MicroClouds can create clusters ranging from 3 to 50 nodes with high availability. The software stack for cluster management is based on the LXD toolkit, the OVN (Open Virtual Network) platform for building virtual networks, and the distributed fault-tolerant storage system Ceph. The setup of LXD, Ceph, and OVN across all cluster nodes is automated. The primary platform considered is the Ubuntu Server distribution, but the toolkit is not tied to Ubuntu and can be used with any distributions that support the installation of snap packages (such as Arch Linux, CentOS, Fedora, Debian, openSUSE, RHEL, etc.). \"Canonical <\/p>\n

To detect new servers<\/a> In networks that can be connected to the cluster, mDNS is used, allowing the entire cluster to be configured by running just one command, «microcloud init» on one of the nodes and the command «sudo microcloud join» on the other nodes, after installing the snap packages lxd, microceph, microcloud, and microovn. After running the «microcloud init» command, the toolkit will detect the presence of other servers in the local network, issue a request to add disks to the shared Ceph storage, and offer to configure virtual network parameters. To add additional nodes after initialization is complete, the «microcloud add» command can be used. The cluster configuration can be saved in YAML format for the subsequent deployment of similar systems. <\/p>\n

The general file storage is created with replication and fault tolerance enabled, allowing data not to be lost in case of failure of individual nodes by storing multiple data instances on different nodes. To deploy storage based on Ceph in the cluster, in addition to local disks, at least three separate disks dedicated to distributed data storage must be present on three different computers. <\/p>\n

Once the cluster is ready, users are granted the ability to run their applications using containers or virtual machines<\/a>, as well as access to the shared Ceph storage and the centralized management tools based on LXD. Flexible management of the provided CPU, memory, and I\/O resources, USB device passthrough, GPU, and drives is possible. Isolated and virtual environments can be migrated between nodes in live migration mode and saved using snapshots. Metrics on cluster performance and logs of events can be exported for monitoring using Prometheus and Grafana. <\/p>\n
