Sundar Pichai, chief executive officer of Google Inc., speaks during a news conference in New Delhi, India, on Wednesday, Jan. 4, 2017.

Google's massive footprint is only getting bigger in 2019.

CEO Sundar Pichai said in a blog post on Wednesday that the company is building new data centers and offices and expanding several key locations across the U.S., spending $13 billion this year.

Pichai outlined the plans, which include opening new data centers in Nevada, Ohio, Texas and Nebraska, the first time the company will have infrastructure locations in those states. The company is also doubling its workforce in Virginia, providing greater access to Washington, D.C., with a new office and more data center space, and expanding its New York campus at Hudson Square.

Google is showing its willingness to further open its wallet, after a year in which capital spending more than doubled to $25.46 billion. Far from its roots as an online advertising giant, Google is building out data centers to bolster its cloud-computing division as it tries to keep pace with Amazon Web Services and Microsoft. It's a business that requires providing fast and reliable computing access and resources to large corporations and government agencies.

Data centers also serve Google's core search, Gmail and YouTube products.
