5. security > resilience > scale

6. velocity > economy

7. architect for change

8. embrace cloud

9. a Starling service
• everything in our core infrastructure is either:
immutable service in EC2 (docker on CoreOS)
data in a managed service
• simple AWS approach - not small
• ELB / ASG / RDS across 3 AZs in eu-west-1
• “service discovery” is just DNS (Route53)
• all specified in CloudFormation nested templates
• with configuration and versions in S3

10. production chaos
• we know we’re resilient because we kill servers all the time

12. Taking it to the next level

PSU held by an ASPSP via an API
• (subject to the RTS for SCA being defined by the EBA)

15. PSD2 & Open Banking
• Open Banking
UK legislation for the big 9 banks
