OREANDA-NEWS. NTT Communications Corporation (NTT Com) announced that it will launch the world’s first software-defined networking (SDN)-based cloud migration service, the On-premises Connection, on July 28 in Japan and later in other markets worldwide. The service facilitates smooth, flexible transitions to the cloud by connecting customer on-premises systems with NTT Com’s Enterprise Cloud via the Internet using SDN technology.

Service features include the following:
* By connecting on-premises systems and cloud in the same network segment using SDN-compatible gateway equipment installed in the customer’s system, the service substantially reduces the workload normally required to design and configure on-premises networks. Also, once in the cloud environment after migration, customers can continue to use the existing IP addresses of their on-premises systems, a further reduction of workload.
* Highly secure, encrypted data can be transferred between on-premises systems and Enterprise Cloud via the Internet at up to 100 Mbps. SDN technology enables customers to make changes promptly and flexibly, such as adjusting bandwidth to transfer large data in off-peak hours. Customers can even use their existing Internet connection lines for cloud migration.
* On-demand use helps to minimize the cost of cloud migration because payment for the service, including gateway equipment, is on a per-day basis.
The initial fee of 220,000 yen includes the cost of installing gateway equipment at the customer’s site. The daily charge is 10,800 yen and the maximum monthly charge has a ceiling of 223,000 yen. Internet connection from on-premises systems and two fixed global IP addresses for gateway equipment are charged separately.

Cloud migration requires servers and data to be transferred sequentially from an on-premises system to the cloud via a network. Conventionally, this involves a vast workload to change network equipment settings and IP addresses in both servers and clients, a huge headache for many customers. In response, the new On-premises Connection Service greatly simplifies the process through incorporation of unique SDN technology, which NTT Com developed in cooperation with VMware, a major virtualization software provider, and a research institute operated by parent NTT Corporation.

Enterprise Cloud allows enterprise customers to build optimal ICT business systems in the cloud by directly controlling global ICT infrastructure via a customer portal. NTT Com developed the service by leveraging its vast experience and know-how as a long-time telecom carrier.
