NTT Communications Corporation (NTT Com) announced to launch on June 29 an infrastructure-as-a-service (IaaS) that incorporates OpenFlow network virtualization technology for networks built within and between data centers.

Called Enterprise Cloud, NTT Com's new IaaS offering will provide global cloud resources for enterprise customers to optimize their information and communication technology (ICT) costs, while expanding their global operations using virtualized servers and networks.

The service will be launched at nine data centers in eight countries by March 2013 -- initially via NTT Com data centers in Japan and Hong Kong, followed by data centers in the US (two locations), the UK and Singapore in December and in Australia, Malaysia and Thailand. Each data center is connected with NTT Com's global network and integrated with network virtualization technology.

According to NTT Com, the new Enterprise Cloud service will enable a service level agreement with "guaranteed availability" at up to 99.99% for service resources. The cloud environment is said to be adaptable to "complex system configurations" that incorporate physical servers and specialized and dedicated equipment of the customer. 

The Enterprise Cloud service will provide on-demand backup via other data centers worldwide using NTT Com's global broadband virtualized networks to ensure cloud-based business continuity. 

The service will also enable users to perform small-increment control of server resources, such as CPU, memory and disk, and network resources including virtual firewall, virtual load balancer and virtualized networks, subscribable on a pay-as-you-go basis down to the per-minute level.

NTT Com also announced the launch of its new managed security services as an optional service for users of Enterprise Cloud service. The security service will comprise unified security management, correlation analyses of security logs and visualization of potential risks by specialists, as well as 24/7 support from over 400 experts in 13 countries, working in partnership with NTT Com subsidiaries Integralis and Secode based in Europe.
