May 2 (Reuters) - Digital Realty Trust beat wall Street estimates for funds from operations on Thursday, driven by strong demand for its data center services, sending its shares up nearly 2% in aftermarket trading.

Data center services are required as businesses integrate generative artificial intelligence into their products and migrate their workloads to the cloud, triggering demand for firms such as Digital Realty.

The real estate investment trust's adjusted funds from operations - a key measure of cash flow - came in at $1.67 per share, compared with analysts' average estimate of $1.63, according to 13 analysts polled by LSEG.

The company posted revenue of $1.33 billion, missing analysts' average estimate of $1.36 billion.

Adjusted core earnings rose to $710.6 million, compared with an estimate of $692.5 million. (Reporting by Jaspreet Singh in Bengaluru; Editing by Pooja Desai)
