How the Open Cloud Exchange works

The Open Cloud Exchange establishes direct, secure and virtual connections to multiple service providers and to the public cloud. All it takes is a single cross-connect in a CoreSite data center. Opening one port into our layer 2 Ethernet exchange enables private virtual connections (VLAN) to AWS, Google Cloud, Azure, Oracle and an ever-expanding ecosystem of business partners and IT services providers.
