NTT Communications has created a comprehensive service to help large enterprises migrate all their workloads to the cloud. Its Enterprise Cloud offering combines its global network, data center and co-location facilities, and software-defined networking (SDN) to pull all the pieces together.

The Japanese company says enterprises are struggling to manage their cloud applications on disparate platforms, whether on-premises or hosted by third parties. In addition, their IT departments are dealing with traditional cloud applications and DevOps-oriented, native cloud applications built by various departments within their organizations.

NTT is pitching its Enterprise Cloud to domestic large enterprises and multinational companies that want to migrate all their workloads to the cloud and standardize their IP environments to provide consistency to their IT departments.

NTT’s Enterprise Cloud creates a cloud management platform to manage a variety of clouds, including multitenant clouds based on OpenStack (for the cloud native applications); hosted private clouds based on VMware vSphere, Microsoft Hyper-V, or baremetal servers; and third-party clouds such as Windows Azure or Amazon Web Services.

NTT’s multitenant cloud is based on OpenStack and incorporates Cloud Foundry to accommodate the cloud-native applications.

“The basic architecture follows OpenStack, but some of the OpenStack components today don’t meet our needs, particularly from the viewpoint of the SDx integration among the data center and the network and the clouds,” said Hideki Kurihara, VP of cloud services for NTT, in a press conference, yesterday. “We built our own network controller with Neutron capabilities, implementing our own proprietary capabilities to connect into the data center and the closed network."

The multitenant cloud and hosted private cloud are connected at Layer 2 with SDN, which gives customers the power to configure the network components (virtual server, bare-metal server, firewall, load balancer) running on a complex on-premises environment in the same network segment.

NTT is using its telecom infrastructure to provide connectivity between Enterprise Cloud and data centers globally.

The service is available in Japan, now, and will be rolled out in the U.K., U.S., Singapore, Australia, Hong Kong, and Germany this year.
