AWS Case Study: Open Universities Australia
OUA is now delivering its applications and websites from a cost-effective, scalable infrastructure with the elasticity to support demand fluctuations and the automation to support continuous delivery. “AWS has given us the tools to release changes in a more flexible and automated way than in our collocated data center. We have been able to look at the steps required to deliver new applications and changes into the environment, and reduce them by applying continuous delivery practices. We now deliver new releases almost every day and greatly shorten the time needed to provide value to our internal and external customers,” says van Eekelen.
OUA now has the ability to change everything in the application stack in a controlled way, and changes can be made in a matter of minutes, allowing the technology team to decrease the time to create a new environment from three months to less than two hours. Formalizing continuous delivery has also enabled van Eekelen to provide a single process for developers to deploy changes to production. “We can now guarantee consistency, quality, and speed to market, and find the information we need to resolve any problems with production at a faster rate,” he says.
AWS has also enabled OUA to establish plans to reduce infrastructure costs by up to 30 percent over the next two years. This equates to up to AU$1 million (US$726,850) in savings relative to the cost of running OUA’s physical infrastructure in the collocated data center. The savings are expected to come from only running OUA’s production systems at peak capacity during enrolment periods, and turning off test and development environments over the weekend and at night. Further, OUA has been able to reduce the cost of database licenses due to the way AWS supports databases through Amazon RDS. “My team has a lot more visibility into costs and can quickly drill down and find out where we might be spending more than budgeted,” says van Eekelen.
While OUA has retained the same number of IT team members, automating the setup of new environments has enabled them to spend more time on higher value work while minimizing infrastructure bottlenecks that could delay projects.
The business is now supporting up to 1,800 views of its higher education web pages and 200 financial transactions per hour during peak periods without performance concerns. “The performance of our websites has improved up to 20 percent in AWS relative to our physical data center. What I’ve found working with AWS—from the start until now—is that they have provided us with a service that makes us want to go back for more,” says van Eekelen.
