The document discusses the implementation of serverless architecture (λ) in government services to enhance performance measurement and transparency. It outlines the challenges faced, such as data integration from various sources, security concerns, and testing methodologies. Additionally, it addresses topics like vendor lock-in and the complexities of serverless configuration.

- 7. 7 —————————————————————————————— Data ๏ Multiple data sources ๏ Disparate data sources ๏ We don’t actually know what they all are yet ๏ We don’t know how much of it we will have

- 10. 10 —————————————————————————————— Data ๏ Connect all the moving pieces ๏ Transform data from many different sources ๏ Move fast ๏ Adapt quickly
- 11. Architecture How are we using λ?
- 12. 12 —————————————————————————————— Caveats We are just finishing Alpha Production this week, pending approvals Going into Beta phase Expanding our usage of λ

- 19. 19 —————————————————————————————— Random Thoughts Vendor Lock In Dependencies Security Testing What about other Amazon products and/or services Zero infrastructure and a surprising amount of configuration

- 22. 22 What about vendor lock-in!!!!?

- 27. 27 —————————————————————————————— Security and IAM • AmazonAPIGatewayAdministrator • AWSLambdaFullAccess • AWSLambdaVPCAccessExecutionRole • ec2:DescribeSecurityGroups • ec2:DescribeSubnets • Built-in Serverless Policy
- 28. 28 —————————————————————————————— Dependencies • Requires some planning • Nest packages with npm • Favour reimplementation of simple helpers rather then pull in a dependency
- 29. 29 —————————————————————————————— Testing • Unit test functions • If testing a function is hard, you are doing it wrong • ava is good • Can run Serverless locally using a plugin
- 30. 30 —————————————————————————————— What about other AWS products • Possible for future development • We’ve played it safe on the database tier • Some limitations to what Gov can support • Contenders: • Kinesis • Elastic search
- 31. 31 —————————————————————————————— Configuration Serverless means replying infrastructure with configuration Don’t underestimate the complexity
