B2EVolution, the cloud computing firm founded by ex-Apple and Microsoft executive Steve Ballmer, said Wednesday that it would close its European office in Berlin.

B2E, which owns B2Evolution, said in a statement that it had made the decision “due to the challenging business environment.”

The move is a sign of how cloud computing and its attendant trends are reshaping the business of technology companies in Europe.

“Today, the B2EC community is facing new challenges, and we’re grateful to B2EG for their support over the past year,” said B2Ecomm CEO André Soderstrom in a joint statement.

The German government, B2EF, B3E, and B3Evolution have been working together since 2013 to help B2EE find a home.

B3EE, which has offices in Berlin, has struggled to find a location, and it has struggled in the past to attract customers, which B2EB said is a major challenge.

But B2ecomm has said that the move was necessary to take advantage of cloud computing, which is becoming increasingly popular and becoming more expensive.
