MAAS documentation
MAAS, or Metal as a Service, transforms physical servers into agile, cloud-like resources. It simplifies the provisioning, monitoring, and management of bare metal servers, enabling remote and automated operations similar to handling virtual machines.
With MAAS, manual management of individual servers is eliminated. You can remotely deploy operating systems to bare metal servers, allowing quick setup, dismantling, and reconfiguration as needed.
Key advantages of MAAS include:
- Automated deployment of operating systems to physical servers.
- Managing large numbers of servers as a unified, flexible resource.
- Central monitoring and management of physical infrastructure.
- Quick setup and removal of server configurations.
- Ideal management of environments needing frequent hardware reorganization.
MAAS is particularly useful in sectors with rapidly changing physical infrastructures, like banking, telecommunications, supercomputing, media streaming, disaster recovery, and computer security analytics. It offers cloud-like flexibility for physical server environments, making it effective for applications needing regular server reconfiguration.
