WSO2Con 2025 - Architecting Cloud-Native Applications

Editor's Notes

• #5: Twitter - Started out as a Ruby on Rails app Cloudflare - Started as a collection of stored procedures written on top of a PostgresDB
• #6: Synapse is a good example here
• #7: Carbon is a good example
• #8: Carbon is a good example
• #9: 2 main methods - Broker method and event coordinator (BPEL)
• #10: 2 main methods - Broker method and event coordinator (BPEL)
• #11: 2 main methods - Broker method and event coordinator (BPEL)
• #13: Lakmal’s talk on how to go from DDD to cell
• #14: Lakmal’s talk on how to go from DDD to cell
• #17: Dynamic compute Pay per use
• #21: Can use strangler pattern here - Incrementally migrate feature by feature to microservices until ultimately ever feature is written/refactored as a microservice
• #23: Complexity: The infrastructure, products and tools needed to build cloud native app is complex Hard to find technical resources: Technically diverse teams of technical resources are needed to manage and maintain the infrastructure, products and tooling. Lack of visibility into developer team productivity / activities. Cognitive load, multiple clouds, high learning curve. Slow to go-to-market: Technology is constantly evolving. Teams are too slow to keep up with this while delivering apps at the speed of business initiatives, resulting in delayed or missed opportunities. These challenges defeat the purpose of moving to cloud native app development if you are trying to build these by yourselves.
• #25: There are no best practices, best practices depends on the use case Always it’s about trade-offs in the face of specific constraints and business requirements
• #26: Best practices doesn’t help much here
• #28: Depends on multiple factors What is the expected latency and performance requirements? What’s the expected reusability? Multiple mobile apps, web apps, services etc…
• #33: Enterprise IT's focus on platform maintenance overshadows application development, where real value lies A mindshare shift is needed: from platform-centric to application-centric, prioritizing innovation over infrastructure Such a shift reallocates people to drive business value, enabling tech roles to focus on delivering solutions, not just supporting systems.
