Mesosphere, a San Francisco-based maker of a "data center operating system," is raising $40 million in new funding, Axios has learned from multiple sources.
In context: Mesosphere is among several companies, including Google, that are helping to popularize new tools for managing servers, data centers, and cloud computing.
Docker, often cited as its main rival, sought to raise up to $75 million a few months ago.
Mesosphere had previously raised $124 million in funding from investors like Hewlett Packard, Intel, Microsoft, Khosla Ventures, Andreessen Horowitz, Data Collective, and Fuel Capital. The company declined to comment.
