Transcript

1. Mauricio Salatino @Diagrid Making your applications environment-agnostic 1

2. 2 Mauricio Salatino @salaboy Ecosystem and Software Engineer

3. 3 Openshift Commons Gatherings What make applications depending on a

   given environment?

4. What is an environment? 4

5. Are these environments? 5 - My local laptop, IDE, CLIs,

   etc - A local Kubernetes clusters using minishift or other alternatives - A CI pipeline like GitHub Actions or the good old Jenkins - A Virtual Machine that I need to login using SSH - OpenShift hosted on Google Cloud

6. Unfortunately, YES! 😐 These are all environments 6

7. Environments have in common: 7 - Must provide an application

   runtime - Must provide the application’s infrastructure - Someone must configure all this infrastructure - No matter the shape or size, how can we decouple our applications from environments??

8. 8 Openshift does a very good job

9. 9 APIs to the rescue!

    reliable distributed apps Dapr connects applications with each other, using any interaction style: • Request/Reply • Pub/Sub • Workflow • Key/Value (Outbox) • Actors • Distributed lock Dapr API Devs Kubernetes runs any application workload on any infrastructure, with consistent abstractions: • Resource constraints • Lifecycle, healthchecks • Deployment and rollback • Policy based placement • Declarative scaling Deploy and operate distributed apps Kubernetes API Ops Storage Application workloads •Red Hat supported: Quarkus, EAP, OpenJDK, Spring Boot, Thorntail, Node.js,JBoss Web Server •Non Red Hat supported in: Go, Node, Python, .Net, Java, C++, PHP, R, Web (HTTP)
