7. Serverless Case Studies
   PhotoVogue is an online photography platform.
   Launched in 2011 and part of Vogue Italia - which
   is owned by Condé Nast Italia - it allows upcoming
   photographers to showcase their work.
   The Benefits
   Quicker provisioning, from days to hours
   90% faster
   Cut IT costs by around 30%
   Seamless scalability

   CloudFront
   “With Amazon API Gateway and AWS
   Lambda, the user experience is up to 90%
   faster. That's for both photographers
   uploading images and the editorial team
   processing them.”

8. 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.”

   Secure, Data-Driven Innovation
   “We are decomposing our applications into smaller,
   discrete components so we can choose the most
   appropriate technology”
   An API-First Approach
   “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”
