■BackgroundThe use of data is accelerating globally while internet user traffic continues to grow with increased use ofAI and big data, not to mention the spread of IoT and 5G, the rise of video streaming services, and theadvancement of cloud services.
To create a digital society, it is becoming increasingly important to have a platform that allows a larger
number of content providers, internet service providers, hyper scalers, and the like to be mutually connected
to generate value.
Furthermore, initiatives will also be taken to improve connectivity between data centers to enable theexchange of domestic and international traffic outside the Tokyo metropolitan area in preparation for majordisasters such as an earthquake directly hitting Tokyo.

■Outline of the provision(1) Optical fiber core connection between data centers
In the OBP area, which is one of the major data center clusters in western Japan, KDDI and JPIX areproviding a service to connect data centers with fiber core, such as TELEHOUSE OSAKA and Equinix IBX
OS3 (*1) in the area.
Prior to this service release, when data center users in the OBP area wanted to establish connection between
data centers, they had to organize their own communication carrier line individually. By using the DCI
service, they can take advantage of a flexible infrastructure that can handle large volumes of traffic at alower cost (*2).
(2) Opening a new IX point of presence and providing additional data center services
KDDI and JPIX will add a new point of presence (POP) for JPIX Osaka and open additional data center
services that will enhance TELEHOUSE OSAKA. These services will be available at several data centers in theOBP area, including Equinix IBX OS3.

Kuniko Ogawa, Managing Director of Equinix Japan K.K. said,“As a global digital infrastructure company with more than 260 data center services, Equinix works with awide range of partners to facilitate our customers' digital transformations. We are excited to work withKDDI and JPIX to bring new value to our customers in the Western Japan region. By combining ourservices, we are confident that our customers' digital transformation will be accelerated even moresustainably and seamlessly."
