What is Landscape?
Landscape is a system management service that allows you to manage multiple Ubuntu machines as easily as one. Canonical Support customers can manage many machines in a complex environment through a single web-based interface. Simply register the machines in Landscape to gain control of numerous systems management and resourcing tools.
What does Landscape do?
Like many businesses yours is likely deploying more Ubuntu machines running more applications and packages. This requires more administration. Additionally, environments are becoming increasingly complex with virtualized machines and appliances running as peers to standard software applications. Ubuntu on server and desktop can run the lot but you need control. That’s where Landscape fits in. There is the package and security updates management you might expect, but Canonical Landscape has also built in a host of additional monitoring, user control, process management, inventory control and support enhancement tools that we describe in detail below.
