NTT Communications Corporation and U.S.-based Verio, wholly owned subsidiaries of Nippon Telegraph and Telephone (NTT) Communications, today announced their selection of Citrix’s CloudStack IaaS platform as a key component of its public cloud service, CloudN. CloudN integrates the robust network infrastructure capabilities of Verio and NTT with Citrix’s CloudStack platform to provide customers with cloud solutions that offer “efficient, limitless scale and fast deployment – all on an open source software platform,” according to Sameer Dholakia, Citrix’s Group Vice President and General Manager. In the case of Verio, CloudN is currently available exclusively to its channel partners and targets cloud solutions focused on the needs of small and medium-sized businesses. Customers will enjoy unlimited inbound and outbound bandwidth for a provisional period after signup. Verio’s strategy of leveraging its channel partnerships in the hosting provider space to additionally offer cloud solutions for small and medium sized businesses represents a key departure from the stampede for enterprise cloud market share that has characterized the overwhelming majority of cloud solutions. NTT’s endorsement of Citrix’s CloudStack, meanwhile, is highly notable given how NTT has been a participating member of OpenStack and recently collaborated with Dell, Rackspace and HP to launch TryStack, a sandbox for OpenStack development.
