Lambda, the user experience is up to 90%
faster. That's for both photographers
uploading images and the editorial team
processing them.”

7. Serverless Case Studies
F-Secure Increases Customer Insight
and Speeds Up Activation Using AWS
“We’ve shown the rest of the
company that we can put our ideas
into action faster and save 70% on
infrastructure costs by using AWS
compared to running hardware on-
premises…. We’re inspiring a shift
toward the cloud, and
microservices in particular,
because of these great benefits.”
Niina Ojala
Service Lead

“We stood up a working prototype in just a few days using
Amazon API Gateway. The speed with which we were
able to deliver it was unprecedented”
