Building with Serverless services at AWS • • • • • Using Amazon CloudFormation/AWS SAM to manage infrastructure Leveraging existing CI/CD tools that have been tweaked to support tools like SAM Difference in telemetry data made up for with more logging and usage of tools like AWS X-Ray Same languages as always: Java, Python, Node.js Little to no changes in development/testing practices: • • • • peer review test in “cloud” linting, syntax checking, unit/service testing canary deploy out slowly & rollback immediately if things go boom © 2019, Amazon Web Services, Inc. or its Affiliates.

What you can do to be like AWS • Organizational structure aligns with microservice based architecture which aligns well with serverless • Standardized, yet flexible tools made supporting serverless essentially “snapping in” new capabilities • CI/CD is a must • Peer review is the one thing you aren’t doing but should • Understanding when you need a REST API vs. using another invoke model • related: Sync vs. async © 2019, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
What you can do to be like AWS • If moving to #serverless feels like a giant shift for your org/team, move slow and purposefully • If someone is telling you that you need all new tools to develop for serverless, they are wrong or selling you something • Potentially something that competes What customers tell me: Serverless benefits pay off vs. the time ramping up © 2019, Amazon Web Services, Inc. or its Affiliates.

In this talk I’ll cover how AWS builds software and how the shift to serverless technologies has, or hasn’t, impacted it. I’ll cover topics around the organizational structure, tooling, and some processes we follow. I will also explore the example of how the team behind AWS Serverless Application Repository has used serverless technologies to build a serverless service.
