The challenge of Byzantine Fault Tolerance

Sometimes it takes a startup to tackle the big problems.

In 2007, XenSource was such a startup, leading the commercial push for the open source Xen Hypervisor. XenSource was acquired by Citrix for $500 million that year, bringing in some of the leaders of the Xen community, including Simon Crosby who served as the CTO of XenSource. In 2011, Crosby left Citrix to start something new -– a company called Bromium.
