5. Replace High Fixed Costs with Low Variable Costs 5 Companies pre-AWS
6. What is Cloud Computing? 6 A broad and deep platform that helps customers build sophisticated, scalable applications ✓ On-demand delivery of IT resources via the Internet ✓ Pay as you go pricing
7. Why are companies adopting cloud computing and AWS so quickly? 7
8. Our journey: Vision 8 • Scale • Low latencies - globally • Your datacenter in git, you can A/B test it • Don’t repeat yourself - make use of managed services
9. 9 Replicate setup in AWS 9 Department • CloudFormation • only managed databases (RDS) • no named servers / ssh access anymore • all dockerized • use CodeDeploy / CodePipeline Backend Plattform Finance Tools End-user Website Refactor setup for AWS best practices Our journey: Strategy
10. Our journey: Tactics 10 1. Setup database / queue master-master replication 2. Bring up duplicated instances at AWS 3. Put 5% traffic to AWS to iron out bugs 4. Put 50% traffic to AWS to A/B test 5. Put 100% traffic to AWS 6. Setup 2nd region in AWS for disaster backup and re-establish master-master replication 7. Return physical server to hoster
11. Our journey: Challenges 11 • Acquire knowledge • Workshop with Consultant / AWS Solution Architect • Sandbox with full admin to all developers • Get buy-in from colleagues • Collect their concerns • Hands-on Hackathon, plattform engineers help them out • Calculate costs together • A/B testing datacenters • Route53 round robin and sticky sessions don’t play well • Branch of at loadbalancer of physical hoster
12. Our journey: Results 12 • Phase I completed, all servers moved • Phase II in progress • Server count trippled • Avg. response time 133ms -> 76ms • Revenue increased by 1.8%
