Currently, Onoko's various social and mobile applications, browser homepages, and browser plugins maintain an average of one million users per day. The company credits AWS with helping it sustain this high level of service while at the same time reducing its operating cost by more than 50 percent since switching from its previous cloud service provider. In fact, the entire operating expense of Onoko's Amazon S3 and Amazon CloudFront services is less than one percent of the company's total revenues.

In addition to the financial benefits the company has experienced with AWS, Onoko is also impressed with the support services of AWS, which help it concentrate on its own corporate goals, rather than worrying about outgrowing its infrastructure.

"AWS has allowed us to focus on building great apps and great user experiences with a very small team," Arulkumarasan says. "With AWS, scalability is never a problem, and we have survived—and profited—from massive spikes of up to 5 million additional users a day without any problems. The AWS staff has been enormously helpful and responsive, and I love how much time AWS developer relations staff spends organizing events and meeting one-on-one to understand our business model and needs."

Onoko is always exploring the possibility of adding additional features from AWS to its current service stack. "AWS keeps innovating new services that make app development easy," Arulkumarasan says. "I still get super excited whenever I see an 'AWS new feature' email."
