1. Mauricio Salatino & Thomas Vitale Spring I/O Barcelona May 30th, 2024 Dapr and Spring Boot Solving the Challenges of Distributed Systems @vitalethomas @salaboy
2. Challenges That you will phase Distributed Systems are complex Developer Productivity Su ff ers writing YAML Teams Expertise to a whole new level @salaboy @vitalethomas https://www.diagrid.io/blog/dapr-for-spring-boot
3. Let’s Start with a Demo Based on https://github.com/dockersamples/example-voting-app @salaboy @vitalethomas
4. Demo @salaboy @vitalethomas https://diagrid.ws/vote

6. Systematic • Software Engineer • CNCF Ambassador, Oracle ACE Pro, Testcontainers Community Champion • Author of “Cloud Native Spring in Action” (Manning). • OSS contributor (Java, Spring, Cloud Native Technologies) Thomas Vitale thomasvitale.com @vitalethomas
7. Where is the application deployed? What is a Cloud-Native Runtime? @salaboy @vitalethomas
8. Where is the application deployed? Is it Kubernetes? @salaboy @vitalethomas ?
9. Where is the application deployed? Or Cloud Services? @salaboy @vitalethomas ? ?
10. Most likely you are using containers @salaboy @vitalethomas
11. Most likely you are using OCI containers @salaboy @vitalethomas
12. Containers save time @salaboy @vitalethomas
13. Shoutout to Testcontainers @salaboy @vitalethomas
14. If you look deeper @salaboy @vitalethomas
15. In a cloud native runtime @salaboy @vitalethomas
16. In a cloud native runtime @salaboy @vitalethomas
17. To make it more complicated… @salaboy @vitalethomas
18. Dapr, can we delegate more responsibility to our cloud native runtime? @salaboy @vitalethomas
19. Dapr - Distributed Application Runtime @salaboy @vitalethomas
20. How does it works? @salaboy @vitalethomas
21. How does it works? @salaboy @vitalethomas
22. How does it works? @salaboy @vitalethomas
23. How does it works? @salaboy @vitalethomas
24. But if you can do that.. you can also do this @salaboy @vitalethomas
25. But if you can do that.. you can also do this @salaboy @vitalethomas
26. How does it works? @salaboy @vitalethomas
27. How does it works? @salaboy @vitalethomas
28. How does it works? @salaboy @vitalethomas
29. What about local development? I don’t want to deploy to Kubernetes… @salaboy @vitalethomas
30. Without Kubernetes (with Testcontainers) @salaboy @vitalethomas
31. Let’s do some live coding… @salaboy @vitalethomas
32. This is good … But can we make it more Bootiful? @salaboy @vitalethomas
33. How do we do this in Spring? Spring Data -> https://github.com/spring-projects/spring-data-keyvalue @salaboy @vitalethomas
34. How do we do this in Spring? Spring Data -> https://github.com/spring-projects/spring-data-keyvalue @salaboy @vitalethomas
35. How do we do this in Spring? Spring Kafka -> https://github.com/spring-projects/spring-kafka @salaboy @vitalethomas
36. How do we do this in Spring? Spring Pulsar -> https://github.com/spring-projects/spring-pulsar @salaboy @vitalethomas
37. How do we do this in Spring? Spring AMQP (RabbitMQ) @salaboy @vitalethomas
38. To provide a better integration we did the same for Dapr @salaboy @vitalethomas
39. (Show application code) @salaboy @vitalethomas
40. But there is more @salaboy @vitalethomas
41. Outbox Pattern * Produce an event every time we store some data * Do it transactionally * If for some reason storing data fails, 
 the event shouldn’t be produced @salaboy @vitalethomas
42. Durable Exections / Workflows * Sometimes we need more than just calling X services in a sequence * We want to make sure that: * If things fail we have a backup plan like: custom retries, circuit breakers and domain-speci fi c logic hooks * Support for long running and stateful interactions, for example waiting for a human input that might be on holidays * That we have compensation logic to undo operations @salaboy @vitalethomas
43. Let’s raffle some books! @salaboy @vitalethomas
44. Deployment @salaboy @vitalethomas
45. What about Deployments? The platform team takes care of wiring up the available infrastructure @salaboy @vitalethomas
46. Thanks @vitalethomas / @salaboy @salaboy @vitalethomas https://www.diagrid.io/blog/dapr-for-spring-boot
