Trainline CTO Mark Holt completed a full infrastructure migration to the cloud through Amazon Web Services (AWS) within 14 months, which has helped the ticket retailer save £1.2 million in capital expenditure every year while keeping operational expenditure flat.
Releases are now broken down into small components rather than kept as monolithic applications, which has helped Trainline go from making one release every six weeks to more than 100 every week.
Holt believes the scale and innovation at AWS sets it apart from older rivals.
"They're managing this massive infrastructure at hyper-scale, and the costs of them doing awesome security is tiny on a per customer basis, but it's incredibly valuable for them to do it," he says.
"Go and talk to some of the other vendors and it's basically just an old style data centre that happens to be in the cloud. That's not quite the same... If you're competing on your ability to run infrastructure, then you've really lost already. Compete on your user experiences, compete on top-line, compete on speed, compete on all sorts of things. But don't compete on the ability to run services.
"Do you want to be on Amazon's innovation curve where they're doing 400 releases a year of actually really cool stuff, most of which is really valuable? Or do you want to be on some legacy vendor who is talking to you about VMware stuff, and you ask for a new server and it takes a really long time for them to install things?"
