Company: Terremark (a Verizon company)
Why they have a shot: In 2011, Verizon bought big into the cloud with its $1.4 billion purchase of Terremark, a leader in VMware-virtualized public IaaS cloud offerings. The brand has grown to include a Private Edition that offers single tenant public cloud; Managed Edition (formerly the Verizon public cloud offering); Express Edition (a pay by the VM public offering); and, Public Sector (a federal community cloud.) Verizon has embraced open standards like Rackspace did with OpenStack, but backs a competing open source cloud scheme, CloudStack.
