Introduction

What is maas
maas is:
MAAS runs a software-defined data centre - it turns a collection of physical servers and switches into a bare metal cloud with full open source IP address management (IPAM) and instant provisioning on demand.
MAAS controls the servers through IPMI or another BMC or converged chassis controller such as Cisco UCS. It provides a full inventory of components, and can install Ubuntu, CentOS or Windows very fast on any server under its control. It can also track and provide DHCP and DNS for other devices on the network.
MAAS handles VLANs and fabrics that span many trunked switches, as well as the routing-centric infrastructure typically used for large-scale OpenStack or other scale-out deployments. MAAS manages IP addresses and provides APIs for address assignment and release. MAAS can also allocate IP addresses for containers on machines, and release them when the machine is repurposed. MAAS provides PXE, DHCP, DNS and other low-level services to ensure the cluster works smoothly.
MAAS works with any configuration system, and is recommended by the teams behind both Chef and Juju as a physical provisioning system.
MAAS provides:
- Hardware inventory of servers
- Dynamic provisioning based on name or attributes such as disk, RAM, cores, nics, networking, gpu’s or architecture
- DNS and DHCP as needed
- PXE boot services
This package is a metapackage which installs all of the separate components of MAAS on a single machine.
