I am using Azure Blob storage for one my microservices. We have a spring boot microservice which I would like to get it triggered every time a a file is uploaded to the blob. I see that apache camel also has a component which supports producer as well as consumer for azure blob storage. What is the difference between spring boot starter for azure blob and apache camel component for the same. I see that I have to write very less code with apache camel. Is there any drawback for using the same.
The camel-azure-storage-blob-starter has a dependency on camel-azure-storage-blob camel-component and provides spring-boot configuration classes to configure the camel component.
If your runtime is spring-boot, you should use the org.apache.camel.springboot:camel-*-starter dependencies.
There is an examples repository for using Camel on Spring-Boot - there is no example for azure-storage-blob, but you can take a look at other components, the bootstrap should be pretty similar.

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 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?
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'm just curious, is it possible to consume Spring Cloud config by a Spring REST service which is not a Spring boot application. If it is possible, where to define the properties in a Spring REST service. I meant, where should I define
spring.cloud.config.uri etc.
Or, only Spring boot applications are allowed to consume Cloud configuration?
Any thought would be appreciated. Thanks
well spring boot just bootstrap all configuration automatically . so for simple spring application you have to config it manually and define the cloud config server beans in your application configuration file . it could be pure old fashion xml files or just using java code configuration with #Configuration. you could find some samples in github
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....
