Summary
In this chapter, we learned how to build an application that leverages on-premise resources. We learned how to use the Secure Gateway integration service to achieve the secure connectivity to the on-premise MongoDB database from your application hosted on Bluemix, which is a public cloud. In this way, we saw how Bluemix provides a hybrid cloud application development environment.
In the following chapter, we will learn how to scale the applications deployed on Bluemix manually, or by using the related DevOps services provided on Bluemix.
