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 enables you to maintain a competitive advantage by delivering 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.

Connect Across the U.S.

Through the CoreSite Open Cloud Exchange, you can connect your national presence and simplify your multi-cloud or multi-site network configuration. With Inter-site connectivity, you can provision bandwidth on-demand between CoreSite campuses for high-speed data replication, machine-to- machine communications, and multi- region cloud network architectures – all with no long-term commitments. SDN Inter-site connectivity is an ideal solution for customers that have multiple CoreSite deployments or need cloud region diversity.
