I was excited to see Tony Hirst retweet the news that Duke University’s website is being run in a Docker environment, and it could even be served through Amazon Web Services. Chris Collins, senior Linux admin at Duke, wrote about “Using Docker and AWS to Survive an Outage” they had as a result of DDoS attacks on their main site back in January. I love the way he tells the story:
While folks were bouncing ideas around on how to bring the site up again while still struggling with the outage, I mentioned that I could pretty quickly migrate the site over to Amazon Web Services and run it in Docker containers there. The higher-ups gave me the go-ahead and a credit card (very important, heh) and told me to get it setup. The idea was to have it there so we could fail over to the cloud if we were unable to resolve the outage in a reasonable time.
TL;DR – I did, it was easy, and we failed over all external traffic to the cloud. Details below.
He goes on to describe his process in some detail, and it struck me how the shift in IT infrastructure is moving, and also made me wonder how many IT organizations in higher ed are truly rethinking their architecture along these lines. It’s one thing to push your services to a third party vendor that hosts all your stuff, it’s all together different to bring in a team that understands and is prepared to move a university’s infrastructure into a container-based model that can be hosted in the cloud. Not to mention what this might soon mean for personal options, and a robust menu of teaching and learning applications heretofore unimaginable. This would make the LAMP environment options Domain of One’s Own offers look like Chucky from Child’s Play 🙂
I know Tim and I are looking forward to thinking about what such a container-based architecture might means for an educational hosting environment that is simple, personalized, and expansive. Tim turned me on to Tutum recently, which starts to get at the idea of a personalized cloud across various providers—something Tim Klapdor gets at brilliantly:
MYOS is very much the model the Jon Udell laid out as “hosted life bits” – a number of interconnected services that provide specific functionality, access and affordances across a variety of contexts. Each fits together in a way that allows data to be controlled, managed, connected, shared, published and syndicated. The idea isn’t new, Jon wrote about life bits in 2007, but I think the technology has finally caught up to the idea and it’s now possible to make this a reality in very practical way.
His post on the topic deserves a close reading, and it’s the best conceptual mapping of what we might build I have read yet. I wanna help realize this vision, and I guess I am writing about Duke University’s move to Docker because it suggests this is the route Higher Ed IT will be moving towards anyway (sooner or later—which could be a long later for some 🙂 ). Seems we might have an opportunity to inform what it might look like for teaching and learning from the ground floor. It’s not a given it will be better, that will depend upon us imagining what exactly a teaching and learning infrastructure might look like. Tim Klapdor has provided one of the most compelling visions to date, building on Jon Udell’s thinking, but that’s just the beginning.
