5. Lambda Function Trigger Do whatever you want: It’s Your Code! S3 Bucket Amazon API Gateway DynamoDB Table AWS IoT Rule Much More! Amazon CloudWatch
6. Lambda Function You can “chain” events to build Event-Driven Applications S3 Bucket DynamoDB Table Lambda Function Mobile App 1. Think Event-Driven 2. Expect Eventual Consistency of Data 3. Design Idempotent 4. Apply the Principle of Least Privilege
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 Amazon S3 AWS Lambda Amazon API Gateway Amazon 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.” Marco Viganò Head of Digital Development
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.” Niina Ojala Service Lead
9. Serverless Case Studies UK Driver and Vehicle Licensing Agency Supports 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” Matt Lewis Chief Architect, Driver and Vehicle Licensing Agency AWS Lambda Amazon API Gateway
