# 5.4 – Deploy, run and test applications in the cloud

Deploy and test your application in cloud can cumbersome. You need:
- Create bastion for individual work stream or project.
- Manage a lot of bastion hosts and user account is really painful.
- Security is always a problem for those bastion hosts.

Take advantage of our Spark Gateway proxy, SSH and SFTP feature. We developed a native agent which will work with the gateway to make this a lot easier. Please check our [Deploy applications in cloud with SparkView](https://docs.sparkview.info/books/sparkview-deploy-applications-in-the-cloud).
