Experiences Even More Speed with Amazon Aurora

TOKYO – June 1st, 2016 – DIGIDAY Japan, which has been using Prime Strategy Co., Ltd. (hereby referred to as Prime Strategy)’s KUSANAGI Fully Managed Service with the ultrafast WordPress execution environment KUSANAGI for AWS, has announced that they have begun using Amazon Aurora and are experiencing even more speed and availability. KUSANAGI itself is capable of an execution time of 3 milliseconds and 1000 requests per second without page caching.

The digital marketing media site DIGIDAY Japan is a Japanese-localized site run by Infobahn Inc. that uses a license from the New York-based DIGIDAY. By using KUSANAGI for AWS, they resolved the performance issues associated with heavy traffic, and were able to create an extremely fast WordPress environment in a very short amount of time.

Now they have begun using Amazon Aurora, and with a slight change in KUSANAGI for AWS, they are experiencing even more speed and availability. Also, they have installed the WordPress plugin HyperDB, and with Read Replicas they have load-balancing and guaranteed performance and availability. With the changes in settings they have switched to PHP 7, and benefit from high performance tuning.

Together with Amazon Aurora and the newest technology offered by KUSANAGI for AWS, they are able to respond to the demands for fault-tolerance. And Amazon Aurora does not hamper the performance of KUSANAGI for AWS, so that they can increase availability and plan for more active development. We hope for 20 companies a year to begin using KUSANAGI for AWS with Amazon Aurora.

Comment from Takumi Miyamoto, Media Development Manager at Mediagene Inc.

Once we began using KUSANAGI for AWS, our performance problems vanished and we reached 14 million page views, but once we made the switch to PHP 7, we received an even greater performance boost. And with Amazon Aurora, we have greater reliability, and can focus more on posting media.

Comment from Yoshihiro Konno, Head of Partner Alliance at Amazon Web Services

We are very glad that enterprises have found a suitable solution with Amazon Aurora and KUSANAGI for AWS, developed by the Amazon Data Services Japan Aurora Ready Partner, Prime Strategy. KUSANAGI for AWS is available in AWS Marketplace, an online store where you can purchase software and services and launch them immediately. It has been adapted rapidly and we look forward to its continued development.

DIGIDAY Japan’s Site Framework

DIGIDAY Japan uses nginx, php-fpm, and Amazon Aurora for its database. It also uses the WordPress plugin HyperDB. With Read Replicas, availability and performance are guaranteed. It utilizes two instances with Elastic Load Balancing to reduce load, and uses Availability Zones to increase availability.
