- 1. Serverless Architecture with AWS lambda @itsmemattchung
- 2. Agenda • Brief background about me • Use Case / Problem • Live Demo • Lessons Learned
- 3. About Me Roots in systems and networking. Primary focus is software development • Engineer @ Cisco Systems • Director.Technical Operations @ Fox Networks (NewsCorp / 21st Century Fox) • Python / DevOps @ Whalerock Industries
- 4. What problem are we trying to solve? • Scheduled tasks • Existing solutions • Cron • Celery beat • RQ
- 5. What is AWS Lambda "... a compute service where you can upload your code to AWS Lambda and the service can run the code on your behalf using AWS infrastructure."1 -- AWS Developer Guide 1 https://forums.aws.amazon.com/message.jspa?messageID=619362
- 6. Attending AWS re:Invent 2015 • Python / Django shop - Celery Beat with single instance scheduler • Lambda as Cron: Scheduling Invocations in AWS Lambda • Using CloudWatch to trigger alarm • SNS topic to trigger AWS Lambda There's got to be an EASIER way
- 7. AWS Announces support for Cron
- 8. A few Core Principles • Pre-production (i.e "DEV", "QA") and production environments • Application logging • Monitoring / Notifications • Easy to deploy
- 9. Live Demo • Trigger web performance tests on a scheduled basis using SpeedCurve API. Sample application • Build • Deploy • Execute
- 10. How to separate environments Each function is its own "environment" • DeploySpeedCurve-dev • DeploySpeedCurve-staging • DeploySpeedCurve-production
- 11. Use Case: Log Ingestion service • Akamai Netstorage • AWS Lambda • SumoLogic
- 12. Things I wished I knew before • Language support • Limitations
- 13. Example code var path = require('path'); path.parse(logfileToUpload) .... TypeError: Object #<Object> has no method 'parse' Worked locally, but NOT on AWS Lambda
- 14. Supported Languages • Node.js: v0.10.36 • Java: Java 8 • Python: Python 2.7
- 15. Limitations
- 16. How to separate environments Environment Variables
- 17. How to separate environment variables (part 2) • Download .env-$ENVIRONMENT from S3 • Invoke Build Process
- 18. How much did we spend the last month?
- 19. Key Takeaways • Treat file system as ephemeral • What language version are you running?
- 20.
