EQIX
Equinix, Inc. Common Stock REIT
stock NASDAQ

AMZN has AWS.
MSFT has Azure.
GOOGL has GCP.
ORCL has OCI.
In years past, most companies invested in one of the above solutions, simply because it was a lot more effort to scale across them. In more recent years, companies (typically larger with low downtime tolerance) have leveraged multiple cloud providers for resilency, redundancy and cost savings pressure. It's also much eaiser to do cross cloud solutions with both infrastructure as code (IaC) and AI.
Of course you still have companies that run their own datacenter footprints (typically alongside a cloud deployment) whether it be in their own space or leased through EQIX/DLR and the like.
EDIT: fix typos
