Introduction
MAAS (Metal as a Service) is a powerful cloud hardware management solution, providing remote automation for bare metal. MAAS allows you to provision physical servers, virtual machines, and network devices for your applications, offering a modern approach to managing your infrastructure.
MAAS is a part of the OpenStack ecosystem, but it can also be used independently. MAAS can be used to manage physical servers, virtual machines, and network devices, offering a modern approach to managing your infrastructure.
Key Features of MAAS
- Cloud hardware management
- Physical server management
- Virtual machine management
- Network device management
- Infrastructure management
Components of MAAS
MAAS has 3 main components:
MAAS Server: This is the main server that contains the MAAS installation. It houses both the Region Controller and the Rack Controller.
MAAS Region Controller: This is the main component of MAAS. It provides the user interface, API, and it manages the provisioning and distribution of the operating system.
MAAS Rack Controller: The Rack Controller provides local network services (such as DHCP, TFTP, HTTP) to the physical servers. Each Rack Controller connects to a Region Controller and provides services to a specific “rack” of servers.
