RFC support on Cloud Foundry - sap

Some months ago there was no Rfc support on Cloud Foundry. It was discussed here
https://blogs.sap.com/2017/09/15/step-11-with-sap-s4hana-cloud-sdk-virtual-data-model-for-bapi/
Are RFC calls supported in the meanwhile?

It is not yet possible to transfer calls that use the RFC protocol via the Cloud Connector from an application running on Cloud Foundry.
I will update this answer once support for RFC on Cloud Foundry becomes available.

Can RabbitMQ SDK be used to operate Azure Service Bus like Kafka for EventHubs?

Azure EventHubs (on tier standard) allows you to use the Kafka SDK. Does Azure Service Bus has a similar feature for RabbitMQ given that both work with AMQP?

How can I configure Redis as a Spring Cloud Dataflow Source?

I've search for examples and I have not found any.
My intention is to use a Redis Stream as a source to Spring Cloud Dataflow and route messages to AWS Kinesis or S3 data sinks
Redis is not listed as a Spring Cloud Dataflow source. Will I have to create a custom binder?
Redis only seems available as a sink with PubSub
There used to be a redis-binder for Spring Cloud Stream, but that has been deprecated for a while now. We have plans to implement a binder for Redis Streams in the future, though.
That said, if you have data in Redis, it'd be good to start building a redis-source as a custom application. We have many suppliers/sources that you can use as a reference.
There's currently also a blog-series in the works, which can be of further guidance when building custom applications.
Lastly, feel free to contribute the redis-supplier/source to the applications repo, we can collaborate on a pull request.

Cloud Foundry on Google Cloud Platform

My application has Jackrabbit Oak implementation, so it uses direct binary upload features through S3DataStore for storing files on AWS-S3. For AWS-S3 integration, we had created service broker instance on Cloud Foundry which was on our on-premises server.
Now I moved Cloud Foundry on Google Cloud Platform, but when I am trying to search AWS-S3 service broker using cf marketplace command. I could not see the aws-s3 service broker.
How to get aws-s3 service broker and if it is not possible then, is there any way to integrate aws-s3 storage with application deployed on CloudFoundry on GCP in case of above scenarios.
It's hard to know what you had deployed on your platform as we don't have any context of what was installed there. Just a guess, but it sounds like you had the Tanzu AWS Service Broker installed. It has service offerings for aws-s3.
https://docs.pivotal.io/aws-services/creating.html#view
You can still install the Tanzu AWS Service Broker when running Tanzu Application Service on top of GCP, you just need to have a AWS account where the broker will create your service instances. The broker creates AWS resources on behalf of the users and it does it under a given AWS account, so as long as you still have an AWS account you can make it work.
That said, there's also a GCP broker that functions in the same, so if you are trying to move off AWS to GCP entirely you could look at using the GCP broker instead. GCP has a similar cloud storage offering.
https://docs.pivotal.io/partners/gcp-sb/index.html
Once you install either broker, you'll see the service plan offerings in your marketplace. If you're still not seeing them, check cf service-access as an admin user. You may need to enable access to those services with cf enable-service-access.
Go back to the team that moved you between CF/AWS and CF/GCP and tell them you need your S3 broker back :)

Deploying the Redis Broker then Redis as a service onto Cloud Foundry

So I am currently trying to deploy the Redis CF service onto Cloud Foundry which is on an Openstack IAAS and getting stuck with deploying the Redis Service Broker. Cloud Foundry is all set up (deployed using BOSH), but how to I deploy the broker? Is it pushed like an application? Do I need to change any files/manifests manually?
The documentation seemed a little light on how I would do this.
Googling "Cloud Foundry Redis service broker", the first result I find is https://github.com/pivotal-cf/cf-redis-release. This appears to document the deployment and configuration steps pretty well in its README. You will deploy the Redis service as a BOSH deployment, and this service includes the broker. You can drive that broker to register it with the Cloud Foundry service broker API as documented in that same README.
There are a couple ways to handle this.
Run open source Cloud Foundry on top of Openstack and then deploy open source Redis (or Redis Cloud, Redis Enterprise, etc.) and connect to it using User-Provided Service Instances
The easiest way is with a Service Broker (aka Pivotal Tile) as Amit describes in the previous answer. Run Pivotal Cloud Foundry on top of Openstack and then deploy a Redis Service Broker, such as Redis Enterprise Service Broker for Pivotal Cloud Foundry and connect to it as documented.
There are other Redis service providers in the The Foundry: such as a9s, IBM, Redis Labs, Pivotal and Swisscom

Legacy application to communicate with cloud foundry using RabbitMQ

I am new to cloud foundry and investigating possible ways for our legacy Java EE application to communicate asynchronously with an application running on cloud foundry.
We are doing a lot of asynchronous work already and are publishing events to Active MQ.
I know that cloud foundry has a possibility to bind with Rabbit MQ and my question is with the possibility for a cloud foundry running application to connect (listen) to an existing out of CF platform Rabbit MQ?
Any idea on other alternatives to achieve this?
Yes, that is possible. You can use a user provided service.
That allows you to inject the environment variables into your app, that are needed to connect to RabbitMQ (like host, port, vhost, username, password).
Once you create that service, you can bind it to your app. Inside your app code, you then can read the environment variables exactly the same way as you would do it, if you had used a RabbitMQ service provided by CloudFoundry.
