One Connection. Countless Opportunities.

The true value of a cloud exchange resides in the ecosystem of service providers on that exchange, and how easy it is to connect to those providers. Established in 2013, the CoreSite Open Cloud Exchange® is one of the first exchange platforms of its kind, built to virtually unite enterprises, networks and cloud service providers, enabling direct access to leading private and public cloud providers, along with network and IT solution providers including AWS, Microsoft Azure, Alibaba Cloud, Faction and Packet Fabric.

How It’s Different

Unlike using the public internet, the CoreSite Open Cloud Exchange establishes direct, secure, virtual connections—enabling more control, reliability, and security for your data. This allows you to deliver your data more efficiently, all with guaranteed throughput and reduced latency. Additionally, our user-friendly online portal allows on-demand access for CoreSite customers to interface directly to virtual cloud environments. Through individualized portals, customers maintain control of data in real time, providing the scalability and elasticity essential for cloud applications.
