But this time, Carrez expounds on the question to ask “What are the tradeoffs of falling behind?”</p> <p><a href="https://www.linkedin.com/in/mdnaser/">Mohammed Naser</a>, CEO at VEXXHOST, lists community-maintained bug fixes as the number one tradeoff to staying up-to-date with the latest release. “T<span style="font-weight: 400;">he closer you are to the supported versions, the easier it is to get your bugs fixed,” said Naser.</span></p> <p>Joshua Slater, Senior Cloud Systems Engineer at Blizzard Entertainment, lists stability maintenance as Blizzard Entertainment’s top priority. This means that <span style="font-weight: 400;">they stay with a reliable release until they are able to say “O</span><span style="font-weight: 400;">kay! Like that’s the killer feature for us to finally go ahead and upgrade,” said Slater. He did, however, mention the tradeoff of “</span><span style="font-weight: 400;">the farther we get behind, the harder it might be to actually perform the upgrade.”</span></p> <p><a href="https://www.linkedin.com/in/inchowdhury/">Imtiaz Chowdhury</a>, Senior Principal Software Engineer at Workday, lists security and staying close to the latest releases as Workday’s top priorities.</p> <p><a href="https://www.linkedin.com/in/arnaudmorin/">Arnaud Morin</a>, DevOps at OVH, notes that “it’s a mixture of all the things [mentioned]” for OVH. “If you stay on an old release…you will end up in situations with security issues you can end up with…And if you want to upgrade you cannot because your OpenStack old version will not work with the new OpenStack version.” He also notes that when you want to introduce new features “you can still cherry-pick and bring them back [to the old OpenStack version], but you will have conflict and it’s more complex.”</p> <p><a href="https://www.linkedin.com/in/belmiromoreira/">Belmiro Moreira</a>, Cloud Architect at CERN, tells us that CERN is always working to run the latest releases. By running the latest release, CERN, like VEXXHOST, <span style="font-weight: 400;">gets active support from the community. “w</span><span style="font-weight: 400;">hen we find the issue, and we expose that issue to the community…</span><span style="font-weight: 400;">it’s much easier to explain it in the latest release, then we go back like five releases,” said Moreira.</span></p> <h3><a href="https://www.youtube.com/watch?v=C2fSy005lDs&t=554s">Is it ok to skip releases?</a></h3> <p>At Blizzard Entertainment, skipping releases is something they commonly do. However, “there are, of course, releases that you cannot skip…One example was when Nova Cells was introduced, we absolutely had to upgrade to that version. And if we wanted to go to a version after that, upgrade again after that, <span style="font-weight: 400;">but we commonly [skip upgrades], because we’re not able to keep up every six months for sure,” said Slater.</span></p> <p>Similar to Blizzard Entertainment, OVH “<span style="font-weight: 400;">skips a lot of releases, but plays every m</span><span style="font-weight: 400;">igration </span><span style="font-weight: 400;">script on the database in order to make sure that everything will be,” said Morin.</span></p> <h3><a href="https://www.youtube.com/watch?v=C2fSy005lDs&t=736s">How frequently do you upgrade to the latest version of OpenStack?</a></h3> <p>Workday, similarly to OVH, has “done big jumps…it is difficult to roll out or do an upgrade on enterprise setting,” said Chowdury. He goes on to mention that “sometimes the network provider, like an SDN provider, can add additional constraints of how often and which release, you can upgrade to.”</p> <p>Finding an effective upgrading process is key to being able to see these upgrades. VEXXHOST has taken a <span style="font-weight: 400;">few steps to get upgrades to be as painless as possible. By </span>“u<span style="font-weight: 400;">sing something like Kubernetes as the control plane for all of our cloud, we can easily roll out a change that just goes out and Kubernetes just goes out and rolls it out across the entire fleet one by one.
