Unlock Data Center Interconnection with CoreSite's Open Cloud Exchange®

In today’s interconnected digital landscape, businesses often work across markets, cloud environments and diverse ecosystems. The ability to bridge these environments is not only key to cross-collaboration and innovation – it’s vital to many organizations’ day-to-day operations and survival.

As a component of the Open Cloud Exchange^® (OCX), Ethernet Virtual Circuits (EVCs) provide secure, private connectivity across leading national markets (or regions), enabling seamless connections to cloud providers, networks and partners.

Data Center Interconnect Explained

Data Center Interconnect (DCI) refers to high-capacity network connectivity between CoreSite markets, enabling low-latency performance across regions. This connectivity allows distributed environments to exchange data efficiently and securely, supporting modern, multi-market architectures. 

EVCs can enable DCI through their highly secure, low-latency data transfer capabilities and seamless access to data across a distributed infrastructure. Provisioned on-demand as a component of the OCX, EVCs operate over private fiber-based networks connecting other CoreSite data centers across different regions. 

With bandwidth options available up to 100Gbps, EVCs are well-suited to support modern, distributed workloads – including high-performance computing, real-time analytics and AI-driven applications. Provisioning takes minutes through the myCoreSite customer portal – enabling faster deployment, easier scaling across markets and greater agility compared to traditional network provisioning timelines.  

Five Advantages of Data Center Interconnect

• Cost-effective data transfer: EVCs route data over Layer 2, also known as the “data link” layer in the OSI model, delivering low-latency, simple set-up – and often at lower costs than using a carrier.
• Regulatory compliance:Compliance requirements may mandate that data remains within specific geographies. EVCs enable organizations to meet these geographic requirements while maintaining secure connections between markets.
• Uptime: Redundant EVCs provide resilience and help ensure high availability.
• Private, high-speed connections: EVCs bypass the internet, avoiding all its performance inconsistencies and security risks.
• Speed to market: Meet your customers where they are, whether that’s in colocation data centers, public clouds or at consumer end points, with the ability to rapidly deploy services.

In addition to DCI, EVCs can support a wide range of use cases:

• Direct cloud connections
• Cloud-to-cloud connections (e.g. AWS to Microsoft Azure)
• BC/DR strategies
• Cross-region cloud connectivity including out-of-region cloud availability zones
• Latency-sensitive workloads such as real-time analytics and AI-driven applications

100Gbps EVC Availability

CoreSite expanded its EVC portfolio with the introduction of 100Gbps connectivity – giving organizations the capacity to support increasingly data-intensive, latency-sensitive workloads across markets.

As infrastructure becomes more distributed, higher bandwidth and consistent performance are critical to maintaining application reliability and user experience. The addition of 100Gbps EVCs enables organizations to scale high-performance computing, real-time analytics and emerging workloads such as agentic AI and large-scale inference with greater efficiency, speed and control.

OCX – The Data Center Interconnect “Easy Button”

One of the most important things to know about the OCX is that it makes managing network services so easy that it only requires a basic understanding of networking to get started. The OCX really is “the easy button” for networking.

As modern, distributed workloads – from high-performance computing to AI-driven applications – continue to expand and demand secure, scalable connectivity across markets, CoreSite DCI capabilities enable seamless connectivity across markets – turning your connectivity strategy into a competitive advantage.
