Curated Supplier · Colocation · US Interconnection

CoreSite — colocation built around low-latency direct cloud interconnect.

CoreSite, an American Tower company, runs about 28 interconnection-dense data centers across roughly 11 major US markets, with native cloud on-ramps to AWS, Azure, Google Cloud, and Oracle through its Open Cloud Exchange. If your problem is getting workloads as close to the cloud as physics allows — private, direct, low-latency — CoreSite is the operator whose whole design answers that question.

What CoreSite actually does.

CoreSite operates around 28 data centers concentrated in roughly 11 major US markets, and its defining feature is interconnection density. Through the Open Cloud Exchange it offers native, software-defined on-ramps directly to AWS, Azure, Google Cloud, and Oracle. The footprint is deliberately tight and metro-focused — this is not a global land-grab; it's an interconnection fabric for enterprises whose latency and private-connectivity requirements are the deciding factor.

Capabilities · A short list

Who this fits.

Best Fit

Enterprise needing low-latency direct cloud interconnect

Organizations whose deciding requirement is private, low-latency connectivity to AWS, Azure, GCP, or Oracle from colocation.

Strong Fit

Hybrid and multi-cloud architectures in major US metros

Teams running hybrid or multi-cloud who want carrier and cloud choice concentrated in connectivity-rich US markets.

Mixed Fit

Buyers needing the broadest global colo footprint

If you need colocation across many countries with a sovereign story, Digital Realty's global platform fits better. Worth comparing.

Less Likely

Organizations needing edge presence in secondary markets

CoreSite's footprint is deliberately concentrated. If you need many secondary or edge markets, Flexential or Cologix may fit better.
