4. Challenges That you will phase Distributed Systems are complex Developer Productivity Su ff ers writing YAML Raise teams expertise to a whole new level @salaboy https://www.diagrid.io/blog/dapr-for-spring-boot
5. Let’s Start with a Demo Based on https://github.com/dockersamples/example-voting-app @salaboy
6. Demo @salaboy https://diagrid.ws/vote-webinar
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
11. Containers save time @salaboy
12. Shoutout to Testcontainers @salaboy
13. If you look deeper @salaboy
14. In a cloud native runtime @salaboy @vitalethomas
15. In a cloud native runtime @salaboy
16. To make it more complicated… @salaboy
17. Dapr, can we delegate more responsibility to our cloud native runtime? @salaboy
18. Dapr - Distributed Application Runtime @salaboy
19. Dapr - Building Blocks @salaboy
20. How does it works? @salaboy @vitalethomas
21. How does it works? @salaboy
22. How does it works? @salaboy
23. How does it works? @salaboy @vitalethomas
24. But if you can do that.. you can also do this @salaboy
25. But if you can do that.. you can also do this @salaboy
26. How does it works? @salaboy
27. How does it works? @salaboy @vitalethomas
28. How does it works? @salaboy
29. What about local development? I don’t want to deploy to Kubernetes… @salaboy
30. Without Kubernetes (with Testcontainers) @salaboy
31. Let’s do some live coding… @salaboy
32. This is good … But can we make it more Bootiful? @salaboy
33. How do we do this in Spring? Spring Data -> https://github.com/spring-projects/spring-data-keyvalue @salaboy
34. How do we do this in Spring? Spring Data -> https://github.com/spring-projects/spring-data-keyvalue @salaboy
35. How do we do this in Spring? Spring Kafka -> https://github.com/spring-projects/spring-kafka @salaboy
36. How do we do this in Spring? Spring Pulsar -> https://github.com/spring-projects/spring-pulsar @salaboy
37. How do we do this in Spring? Spring AMQP (RabbitMQ) @salaboy
38. To provide a better integration we did the same for Dapr @salaboy
39. But there is more @salaboy
40. Outbox Pattern https://docs.dapr.io/developing-applications/building-blocks/state-management/howto-outbox/ * 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
41. Durable Exections / Workflows https://docs.dapr.io/developing-applications/building-blocks/work fl ow/ * 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
42. Let’s raffle some books! @salaboy
43. Deployment @salaboy
44. What about Deployments? The platform team takes care of wiring up the available infrastructure @salaboy
