Peltola measures success in the availability of the infrastructure, and the experience this gives end users around the globe. “Our games are played worldwide, so having good connectivity helps us ensure that users have a seamless experience with quick response times, wherever they are. We can’t provide a reliable service unless we can rely on AWS, so for us, the most crucial measure of our success is our uptime—the fact that our services are up and responding promptly. We’ve always had good availability with AWS.”

Rovio takes its responsibility to customers seriously, and understands that the way it handles customer data is crucial to this. “If our users don’t like what we do or how we do it they can go elsewhere, so if we give the impression that we haven’t taken care of our customers’ data, this would have an instant impact on our reputation,” says Peltola, who finds that the cloud helps him in a number of ways when it comes to security. “One is that with AWS we have fewer security concerns—we don’t have to worry about data center access controls on a physical level, for example. We also get to benefit from all the development work that AWS does in control, auditability, and encryption. In the AWS cloud environment we have better, more affordable security tools available to us than in a traditional infrastructure.”

The Hatch team at Rovio also values the automation of AWS, and its flexibility—both in terms of ease of use and the scalability of resources. “With AWS we benefit from being able to scale on demand, and we also have access to APIs to automate how we use the service. Automation and scalability go hand in hand: you can’t scale on-demand if you can’t automate, and automation is no good if you have to wait a few weeks for a server to be installed. Being able to easily automate our infrastructure and scale to meet massive spikes in demand are two of the things we value most about AWS.”

An example of the scale required comes from the August 2015 launch of the sequel to the original Angry Birds game. “Big launches are always exciting times, but they’re also extremely nerve-wracking,” says Peltola. “With the Angry Birds 2 launch, we reached 10 million users in around three days. We were picking up about 120,000 new users every hour, and our AWS-powered platform had to keep up with this level of demand all weekend.”

Analytics has become a key part of how Rovio gets insight into its games to ensure they stay attractive to users. “We started to use Amazon Redshift in addition to Amazon EMR to give more power to our analytics. To give you an idea of scope, our analytics stack receives about three billion events a day,” says Peltola. “We can do the heavy computational jobs a lot faster than we could do with most other systems out there. This gets vital KPIs to our internal teams faster, enabling them to understand how games are performing and ultimately improve the end-user experience.”
