IBM Cloud Hybrid Messaging Reference Implementation

Solution Overview

This project provides an end-to-end reference implementation to demonstrate how to implement hybrid messaging that connects public cloud to on-prem systems via a secure messaging solution. It uses Bluemix Secure Gateway to communicate to MQ deployed on a SoftLayer VM image (to mimic on-prem deployment)

The project also provides a simple Node.js application that publishes and subscribes to the MQ topics via MQLite protocol. It is deployed to Bluemix as a Cloud Foundry application.

Setup the MQ on SoftLayer

Install a version of MQ on the SoftLayer VM that supports AMQP. Create and start a Queue Manager. Create and start the AMQP service.

Setup a Secure Gateway service on Bluemix

1. From the Bluemix Catalog, select Secure Gateway
2. Click CREATE
3. ADD GATEWAY
4. Name GatewayToLocalMQ
5. Add a destination, named OnPremMQ
   • On-premises
   • SoftLayer VM's IP address
   • Port 5672
   • Using TCP

Setup the Secure Gateway client on SoftLayer

1. FTP Secure Gateway Client installation package to /tmp directory
2. cd /tmp
3. rpm -ivhf [file-name].rpm
4. Start the client (after defining the Secure Gateway on Bluemix):
   1. cd /opt/ibm/securegateway/client
   2. node lib/secgwclient.js [gateway-id] --t [security-token]
   3. acl allow :5672
5. After the Secure gateway client is started, the Secure Gateway on Bluemix will show as connected.

Run the app on Bluemix

1. Download and extract the code
2. cd into the app directory
3. cf push mqlight-sample
4. Add the following environment variables to the sample app:
   • MQ_SERVER: The secure gateway’s cloud host
   • MQ_PORT: The secure gateway’s cloud port
   • MQ_USER: A VM userid
   • MQ_PASSWORD: The associated VM password
