VPN and Remote Networks
Another aspect of network security is the connectivity you establish between your on premise data center
and the vCloud Air cloud. Based on the workload, a virtual machine can have various connectivity needs.
vCloud Air supports Internet, secure VPN, and Direct Connect secure connections between your remote site
and the vCloud Air cloud.
Each type of connection has different security features:
n
Secure Internet connectivity with firewall rules (a gateway service)
See “About Firewall Rules,” on page 28 in this guide for information.
n
Secure VPN:
n
IPsec VPN—secure site-to-site VPN
See “About IPsec VPN,” on page 31 and “Set up an IPsec VPN Connection to a Remote Site,” on
page 32 in this guide for information.
n
SSL VPN (Data Center Extension)—extension of your existing IP address range from your on-
premise data center into the cloud with Layer 2 extension
See “SSL VPN for Data Center Extension,” on page 34 in this guide for information.
n
Direct Connect—private connectivity providing a dedicated, connection (ideal for regulated
applications)
See Chapter 5, “Direct Connect for vCloud Air,” on page 41.
Create an IPsec VPN connection by using vCloud Air and vCloud Director. Create an SSL VPN (Data Center
Extension) connection by using vCloud Connector.
