Deploying and managing private clouds has traditionally been complex, time-consuming, and resource-intensive. Setting up all the required components like virtualization, storage, and networking from scratch. It requires deep technical expertise across multiple domains.
Even for experienced infrastructure engineers, building and operating private clouds can be frustrating. The setup process is manual and tedious. Ongoing maintenance is challenging with so many moving parts. Upgrades and security patching turn into headaches.
The result is private cloud environments that are:
- Difficult to deploy - Require weeks or months of complex configuration and integration work.
- Hard to operate - Day-to-day management consumes significant time and effort.
- Rigid and static - Can't adjust quickly to changing needs.
- Vulnerable - Lagging behind on security updates and bug fixes.
Clearly, there had to be a better way. Enter MicroCloud.

Under the Hood of MicroCloud
MicroCloud achieves its magic through proven open-source technologies tightly integrated to work together flawlessly
1. LXD for Virtualization
LXD provides powerful hypervisor-level virtualization using both virtual machines and Linux containers. It includes:
Image Source: Ubuntu
- Image-based workflows - Preconfigured images for fast deployment.
- VM support - Run traditional virtual machines side-by-side with containers.
- Scalability - Manage tens of thousands of instances from a single host.
- REST API - Automate provisioning and management programmatically.
With LXD, MicroCloud delivers excellent density and performance for large and small workloads.
2. Ceph for Storage
For storage, MicroCloud utilizes Ceph, the leading open-source software-defined storage platform. Ceph offers:
Image Source: Ubuntu
- Unified storage - Block, file, and object storage in one cluster.
- Limitless scalability - Scale to exabytes without architectural limits.
- No single point of failure - Data is replicated avoiding downtime.
- Commodity hardware - Use affordable, off-the-shelf gear.
Ceph provides MicroCloud with robust, resilient storage that grows seamlessly on demand.
3. OVN for Networking
Connecting everything together is OVN, an advanced open-source virtual networking solution. OVN enables:
Image Source: Ubuntu
- Overlays - Create virtual Layer 2 networks for segmentation and isolation.
- Security groups - Build complex security policies for workloads.
- Load balancing - Distribute traffic across application tiers.
- Automation - Programmatically manage networking configurations.
With OVN, MicroCloud gains flexible software-defined networking suitable for multi-tenant environments.
Key Capabilities
The combination of these battle-tested building blocks gives MicroCloud some powerful capabilities
1. Deployment Automation
MicroCloud uses Ansible under the hood to automate deployment and lifecycle management. The microcloud command handles all the complexity for you.
To deploy MicroCloud, you simply:
- Install 3 or more Ubuntu servers.
- Run
microcloud initon one server. - Answer a few prompts about your environment.
That's it! The rest happens automatically with no manual configuration required. You'll go from zero to a fully functional private cloud in about 10 minutes.
2. Built-in High Availability
MicroCloud is highly available by design. A minimum of 3 nodes are required to provide redundancy across the control plane.
The Ceph storage backend replicates data across nodes protecting against failures. If a node goes down, workloads will automatically restart on the remaining nodes without disruption.
3. Snap Package Management
All MicroCloud components are packaged as snaps - secure, isolated, self-contained packages. Snaps make deploying and managing MicroCloud simpler with the following:
- Automatic updates - MicroCloud stays up-to-date with one command.
- Dependency management - No need to install prerequisite libraries.
- Rollback - Instantly revert to previous versions if needed.
- Strict confinement - Components are isolated from each other and the OS.
Snaps take the pain out of administering MicroCloud.
4. Multi-Tenancy
MicroCloud includes everything you need for secure multi-tenant environments:
- Remote authentication - Integrate LDAP, Active Directory, SAML and more.
- RBAC - Granular role-based access control for users and groups.
- Projects - Logically isolate teams into separate security domains.
- Quotas - Limit resource usage by project.
You get full control over users, workload isolation and resource consumption.
MicroCloud Use Cases
With its unique blend of automation, efficiency and scalability, MicroCloud is ideal for
1. Edge Computing
MicroCloud is perfect for distributed edge environments:
- Scale-out - Easily repeatable deployments across locations.
