DLR vs CARR Comparison

Digital Realty owns and operates over 300 data centers worldwide. It has nearly 40 million rentable square feet across five continents. Digital's offerings range from retail co-location, where an enterprise may rent a single cabinet and rely on Digital to provide all the accommodations, to "cold shells," where hyperscale cloud service providers can simply rent much, or all, of a barren, power-connected building. In recent years, Digital Realty has de-emphasized cold shells and now primarily provides higher-level service to tenants, which outsource their related IT needs to Digital. The company operates as a real estate investment trust.
