Europe has five major data center markets which include the cities of Frankfurt, London, Amsterdam, Paris, and Dublin. Indeed, these five cities are known as the “Tier 1” markets of Europe. Additionally, the cities of Frankfurt, London, Amsterdam, and Paris are commonly referred to as the “FLAP” data center markets. Below we outline the supply and demand metrics for each of these booming European data center markets. Notably, this European update follows our prior article on the top 5 data center companies, in the largest 7 markets across the United States.

Frankfurt, Germany – Data Center Market
