With the rise of white box environments network equipment is being liberated from captive pre-installed network OSes. You can now choose your bare metal switch hardware and operating system separately and then change it trivially later. Surely this creates chaos and a compatibility nightmare I hear you say.

Installing SaltStack can be a pain as there is some initial installation and configuration needed before Salt can actually be used. This post shows how you can install and operate Salt on a Cumulus Linux switch without ever needing to log into the switch directly. The operations shown below can easily be expanded to install many switches at once. Continue reading
The SUSE Linux vendor runs a six-monthly survey on OpenStack users’ attitudes and deployments. The results of this bi-annual report, completed by some 1315 individuals across the planet, are just in.
Headlines include that 60% of deployments are now in production, compared to 32% under two years ago, and twice as many users filled in the survey this time. Over half the community works in cloud operating, which I guess is no surprise. What was more surprising to me was that the size of organisations using OpenStack (in terms of headcount) is fairly evenly distributed. For example, the number of OpenStack-using companies with 1 to 9 employees was similar to those with 100,000 or more. Although, as a trend, the uptake in larger companies is increasing survey to survey, maybe they are having a slower incubation time to get OpenStack into production. Continue reading
Recently we had the need to install a number of Ubuntu boxes for a client. Whilst our usual home-grown scripts with Kickstart and Salt work just fine, they are not the most intuitive to hand over or maintain. So we used Canonical’s MaaS or Metal as a Service. We are talking tens of machines, not thousands, so we created a single node MaaS installation. This gives flexibility for future deployments, as MaaS can install a number of different operating systems.
This is a walk through of what turned out to be a very quick and easy install. Now we can install servers on
mass maas. Continue reading Today we are looking at MaaS from Canonical, the makers of Ubuntu. MaaS, which stands for Metal as a Service, promises to automatically and dynamically provision your servers. It’s the same idea as cloud provisioning, but now with your own bare metal servers. Very exciting indeed, so we thought we would give it a try. Continue reading
Are you still running down to the datacentre to install your Linux machines with a CD? Is it still taking you hours to install a new machine? You can’t be a hyperscaler if you don’t automate your server installs. Continue reading
