Leveraging Serverless Architecture for Agile Software Development (AWS Community Day 2023)

In this session from AWS Community Day 2023, I break down how shifting to a serverless mindset can supercharge your Agile development loop. Drawing from my own experiences building and scaling tech products, I explore how eliminating server management directly translates to faster iteration, lower time-to-market, and a sharper focus on user needs. I walk through practical AWS serverless patterns—from simple apps to complex image processing workflows—and share hard-earned best practices on application design, CI/CD, and cost optimization to help your team build evolutional architectures that embrace change.

10. Benefits of Serverless for Agile
11. 1 Benefits of Serverless for Agile REDUCED TIME TO DELIVER TO MARKET INCREASED FOCUS ON THE CUSTOMER’S NEEDS IMPROVED COLLABORATION WITHIN THE TEAM 2 3
12. Example Serverless Architectures My Personal Experiences
13. Single Page Application
14. Simple PHP Application
15. Image Processing
16. Best Practices (Again) My Personal Experience
17. Application Design 1.Modular, well-encapsulated and loosely coupled architecture design. 2.Lightweight model for custom ad-hoc code 3.Stateless Application
18. Develop and Operate 1.Continuous delivery and deployment 2.Multiple environments (Development & Production) 3.Infrastructure as Code 4.Monitoring 5.Empower with resource autonomy.
19. Budgetary 1.Leverage Free-Tier (e.g. 1million request Lambda) 2.Tag resource by team / projects / products 3.Implement Cost Policies 4.Evaluate ROI periodically
20. Learn and Embrace Change 1.Learn about customer. 2.Learn about your team. 3.Always experiment to deliver value 4.Architecture is evolutional. Always prepare for improvements.
21. Conclusion
22. Q&A Let’s discuss!
