Ubuntu Systems Management update
We released a new version of Landscape our management service for Ubuntu last week. There’s a slew of new features including server templates, simple upgrades and enterprise authentication support. Whether you’re managing a few systems or as many as Google the new features make system administration simpler!
Landscape’s objective is to make managing and monitoring hundreds of Ubuntu systems as easy as looking after one. Whether you’re managing some Ubuntu desktops, or looking after a Web server farm Landscape lowers the complexity of administering those systems: no-one wants to apply patches to hundreds of machines manually! For IT managers this means that Landscape makes system administrators more effective and efficient. Landscape also ensures that deployed Ubuntu systems are secure with maintenance patches and upgrades.
Landscape is provided as a software service so every six months Canonical releases a new version that is available to all subscribers. There’s also an on-site version available to customers that have security policies or regulations that prevent them using a SaaS management platform. In line with Ubuntu 10.04 the main features of the new version are:
Many sites have sets of servers that do similar jobs, for example “web serving“. Ideally you want those machines to have the same set-up reducing management overhead.
The ability to create templates of the packages installed on a particular system and then apply those to different machines makes it easy to replicate a standard install. It also ensures that you maintain consistent profiles across your systems as time goes by. Finally, if you need to re-provision or expand resources you can use profiles to ensure it’s a repeatable process. Package Profiles is really great for managing configurations.
If you’re managing more that a handful of Ubuntu systems then doing upgrades is going to take a lot of time. Whether that’s every six months in time with the standard releases, or every two years for the LTS releases, it’s a significant commitment. To reduce that overhead you can now do upgrades between releases using Landscape.
Upgrades between releases are always complex so this doesn’t remove the need for backups and careful attention. Nonetheless, if you’ve used Package Profiles, it will be easier to test an upgrade on a test system and then when you’re happy apply it to all the deployed systems using the same package profile. Rather than having to access every machine and do the process by hand you can upgrade a group at a time.
Enterprises commonly have a corporate standard for authentication such as LDAP or on a Microsoft Windows network Active Directory. The new version of LDS connects to these systems authenticating administrators from the existing authentication system. This ensures that customers can simplify their authentication set-up and enforce authorisation from a single corporate directory.
