The new release of Landscape in time for the Ubuntu 10.04 LTS release attracted some nice articles in the Linux press. The majority of the features this time around are designed to help enterprise Ubuntu users who are managing a large number of systems. If you have hundreds of servers in your enterprise then you need to be able to see the “Landscape of your deployment” and react to issues quickly. There’s more detail on the main features in my previous Landscape post.
First up is Sean Michael Kerner at Linux Planet who did a nice write-up titled Canonical Landscape 1.5 Extends Ubuntu Linux Management for Enterprises on the release. He pays particular attention to the enterprise authentication and the LTS upgrades with a nice quote from Ken Drachnik:
“We find that most enterprises are using LTS’s, so as part of this release, we wanted to have the automated ability to just click a button and say ‘Yes, upgrade me’ and then Landscape would automatically download the packages and do the upgrade”
Over at The Register, Timothy Prickett Morgan focuses talks about the Cloud aspects of the new release in his article Canonical updates Landscape manager. With UEC a key part of our server product and the work we’re doing on Amazon EC2 there’s lots of interesting things that Landscape can do to help users manage Ubuntu in these environments.
Finally, Joe Panettieri at WorksWithU discusses Landscape 1.5: The Implications for Ubuntu Customers and Partners where he summarises the key elements of the release and considers how the Amazon EC2 management might be of interest to partners. He specifically asks for examples of how Landscape is being successful with corporate customers. And as if by magic we can point him at this case study by PlusServer AG which we just put up, and it’s definitely worth a read!
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.
