Amazon RDS on VMware networking now simplified and more secure

Amazon RDS on VMware no longer requires the use of a Virtual Private Network (VPN) tunnel back to AWS. By removing the VPN tunnel requirement and moving to HTTPS, we’ve simplified the preparation that is required on your network to be able to take advantage of Amazon RDS managed database services in your VMware vSphere clusters on-premises. You are no longer required to open up the VPN ports in your corporate firewalls, nor add a VPN Originator, and can potentially lower your setup and operating costs.
