Availability has also been positively impacted. The back-to-school period is the company’s busiest time of year, and "you have to keep applications up," says Somogyi. Before, this was a pain point for the legacy infrastructure. Now, for the applications that have been migrated to the Kubernetes platform, "We have 100% uptime. We’re not worried about 9s. There aren’t any. It’s 100%, which is pretty astonishing for us, compared to some of the existing platforms that have legacy challenges," says Shirley.
"You can’t even begin to put a price on how much that saves the company," Jackson explains. "A reduction in the number of support cases takes load out of our operations. The customer sentiment of having a reliable product drives customer retention and growth. It frees us to think about investing more into our digital transformation and taking a better quality of education to a global scale."
The platform itself is also being broken down, "so we can quickly release smaller pieces of the platform, like upgrading our Kubernetes or all the different modules that make up our platform," says Somogyi. "One of the big focuses in 2018 is this scheme of delivery to update the platform itself."
Guided by Pearson’s overarching goal of getting to 200 million users, the team has run internal tests of the platform’s scalability. "We had a challenge: 28 million requests within a 10 minute period," says Shirley. "And we demonstrated that we can hit that, with an acceptable latency. We saw that we could actually get that pretty readily, and we scaled up in just a few seconds, using open source tools entirely. Shout out to
Locust for that one. So that’s amazing."

In just two years, "We’re already seeing tremendous benefits with Kubernetes—improved engineering productivity, faster delivery of applications and a simplified infrastructure," says Jackson. "But this is just the beginning. Kubernetes will help transform the way that educational content is delivered online."
So far, about 15 production products are running on the new platform, including Pearson’s new flagship digital education service, the Global Learning Platform. The Cloud Platform team continues to prepare, onboard and support customers that are a good fit for the platform. Some existing products will be refactored into 12-factor apps, while others are being developed so that they can live on the platform from the get-go. "There are challenges with bringing in new customers of course, because we have to help them to see a different way of developing, a different way of building," says Shirley.
But, he adds, "It is our corporate motto: Always Learning. We encourage those teams that haven’t started a cloud native journey, to see the future of technology, to learn, to explore. It will pique your interest. Keep learning."
