I haven't seen any example of combining the two, even though it makes sense they'll work together (because of being both subprojects of Spring Cloud). I want to use Spring Cloud Stream (Reactive Processing) for reading from Kafka and writing to MongoDB with the Reactive Mongo driver. Can I use Spring Cloud Config and Spring Cloud Kubernetes for a remote git configuration server, even though the application is an event-driven application and not a requests-based API?
It's pretty unclear how to plug these Kubernetes and config projects into Spring Cloud Stream, and in general, it's unclear to me if all of the other Spring Cloud projects can work with Spring Cloud Stream reactively. For instance, I couldn't also find a reference for using Spring Cloud Sleuth & Zipkin with Spring Cloud Stream. Can someone make it clearer for me and reference code examples if exists?

I am using spring boot with Kubernetes and Eventhub. To connect with Azure Eventhub i use spring cloud stream. What is the math to determine the number of pods assuming non reactive spring boot application with apache tomcat?
Edit 1: to reframe my question, how do you factor in spring boot performance , request rate , user count, etc while scaling the pods?
In general the number of pods can be managed with a Deployment in Kubernetes. For more information you can see here kubernetes.io. In a Deployment you tell Kubernetes how many Replicas you want, which means how many Pods should be running. I don't know what you mean with non reactive spring boot application with apache tomcat. I also don't know about spring cloud stream.
I am trying to find some examples of Spring Cloud Data Flow and Azure Service Bus setup. .
I have found https://github.com/microsoft/spring-cloud-azure/tree/master/spring-cloud-azure-stream-binder/spring-cloud-azure-servicebus-topic-stream-binder but it is still in RC and I do not see any examples (which cover Spring Cloud Data Flow) there.
Could you please help me to understand if I can use Spring Cloud Data Flow and Azure Service Bus together?
I was able to run examples with Kafka and RabbitMQ, but I cannot find anything about Azure Service Bus that can be used as the integration solution for Spring Cloud Data Flow
Spring Cloud Data Flow doesn't necessarily need to know what messaging layer you choose to run your applications on. Hence, your question is more likely related to how one can run the application with Azure Service Bus using Spring Cloud Stream.
This is one such a sample: https://learn.microsoft.com/en-us/java/azure/spring-framework/configure-spring-cloud-stream-binder-java-app-azure-event-hub?view=azure-java-stable
Once the application is built using Spring Cloud Stream (using the Azure event hub binder), you can then manage these applications using Spring Cloud Data Flow as Streaming applications.
Can Spring Cloud Data Flow be used in Spring5 applications - NOT Spring Boot - my current employer seems to view Spring Boot applications as insecure (I've no idea why) in anyway I'd like to try use this stack for an integration project, so is it possible to use it without Spring Boot?
With Spring Cloud Data Flow you can deploy streams, tasks and batches.
This is all based on Spring, Spring Cloud and Spring Boot. Spring Boot is nothing else as a preconfigured Spring stack.
Spring Data Flow is a runitme that usually needs a cloud infrastructure like Kubernets.
I'm not sure if you really are looking for that or more for something like https://spring.io/projects/spring-integration
I am very new to Elastic APM and not sure how it can support different frameworks. I can see that from the documentation APM supports Spring Boot. I have tested a Spring Boot application with the APM and it looks promising. I was wondering if APM supports Spring Cloud Stream as well. Spring Cloud Stream provides Event Driven Architecture by using Spring Boot and messaging middleware. Middleware can be Kafka, RabbitMQ, etc.
I am not familiar with what is Elastic APM, but if it says it supports Spring Boot, then it means it supports any spring-boot-based framework which Spring Cloud Stream is.
We are planning to move a Spring based application to Cloud Foundry.
The application currently uses WAS server and access data sources using JNDI lookup.
We are using spring features like MVC, AOP etc.
I have certain questions in mind :
Is it possible to switch to Tomcat and configure dataSources using Spring-cloud-connectors and possible conflicts we might run into ?
Currently , datasources are configured in XML files, Should I use the same XML files or switch to annotations.
Can anyone please provide some clarity over this and other known issues with this approach?
Spring Cloud Connectors are by far the easiest way to bind to data sources in Cloud Foundry. I would recommend converting your JNDI lookups to use these service connections as described here:
http://docs.cloudfoundry.org/buildpacks/java/spring-service-bindings.html
cloud foundry automatically reconfigures your datasource when it find a database service attached the cloud app. its super coooool....
