KieLive#18: Kogito - Powering Business Automation in the Cloud

The cloud is the new runtime for modern business applications where solutions are now built by composing multiple microservices. In this context, developers need tools that help create, adapt or extend their applications with the agility needed by the modern business world. But how do business automation solutions fit in this space? Why and how does the design of Kogito components support truly cloud-native applications?

With Cristiano Nicolai, we will explore all the components you can use from Kogito, how these are interconnected and can help you create tailored solutions based on your business domain using state of the art runtimes such as Quarkus and Spring Boot.

2. What are cloud-native applications? “Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach. These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.” Cloud Native Computing Foundation (CNCF)
3. What are cloud-native applications? • Small, independent, and loosely coupled services ◦ Microservices • Container based • Allows rapidly iteration to deliver business value • Private, public, and hybrid clouds • Scalable, resource efficient
4. Cloud Native Applications Architecture OpenShift / Kubernetes Operators KNative Service Mesh Serverless SaaS Cloud Vendor Services
5. • Runtimes • Add-ons • Services • Operator Kogito Cloud Native Building Blocks
6. Kogito Runtimes
7. Automagically REST! • Kogito resources ◦ BPMN ◦ DMN ◦ Serverless Workflow i. JSON ii. YAML
8. Kogito Runtimes Quarkus Spring Boot
9. Kogito Add-ons
10. Kogito Runtimes - Add-ons • Building blocks ◦ Choose and pick the ones that are relevant to your service • Maven dependencies • Codegen integration • Runtime specific dependencies: ◦ Quarkus ◦ SpringBoot <dependency> <groupId>org.kie.kogito</groupId> <artifactId>kogito-cloudevents-quarkus-addon</artifactId> </dependency>
11. Management add-on • Retrieve process nodes • Abort an active process instance • Cancel or re-trigger a node instance, or trigger a new node instance • Retrieve error details for a process instance, or skip or re-trigger a failed node instance
12. Management add-on
13. Persistence add-ons • Infinispan • MongoDB • File system • Disclaimer: Persist your process state while it is running!
