Integration projects can be complex and include multiple services. In the world of WSO2 ESB, these services are created and uploaded as CAR files. We have rolled out a nice little Integration Cloud improvement that makes hosting such projects easier. Any ESB app in Integration Cloud can now have multiple CAR files uploaded and running. When you create a new ESB app or a new version of an existing app in Integration Cloud and you have multiple CAR files, simply browse to each of them one at a time, and the system will get all of them uploaded and added to the runtime: When you scale this application to multiple instances, each new instance automatically gets all the CAR files that you uploaded. And you also save money and compute resources because the same ESB instances are reused across the projects. Happy integrations!
