ISTS Running KUSANAGI + FastlyExperiences 10 Times Speed At Home And Abroad

TOKYO – July 7th, 2016 – Prime Strategy Co., Ltd. (hereby referred to as Prime Strategy) today announced it had installed its ultrafast WordPress execution environment KUSANAGI to the ISTS ( International Symposium on Space Technology and Science ) . KUSANAGI is capable of an execution time of 3 milliseconds and 1000 requests per second without page caching.

Issues of the ISTS web site

・Took time to display pages abroad having many accesses.
・Concern about strikes against the website.
・When accessed to the Webserver it’s concentrated during the conference and the server was ready to shut down.

Reasons for using our services

・High speed performance was needed.
・PV increase through high-speed performance and higher order of retrieval sequence.
・The UI of administration screens were old, so they had to be renewed.
・Speedy response to the accesses from abroad was needed.

ISTS’s Site Framework

ISTS uses Nginx, HHVM, and MariaDB Galera Server, KUSANAGI for SoftLayer and Fastly that is a powerful real-time CDN.
By introducing Fastly, the performance of the ISTS website has improved dramatically, although the accesses from the USA, Germany, France, and recently from the Middle East, South-Eastern Asia, China, Korea were concentrated during the conference.

KUSANAGI for SoftLayer

Comment from Miwako Shimizu, the Chief of ISTS Organizing Committee

The size of the information of this website took too much time to update pages and programs. When accesses from the USA, Germany, France, and recently from the Middle East, South-Eastern Asia, China, Korea were concentrated during the conference, the server was ready to crash. After the previous conference, we desided to introduce KUSANAGI. I’m looking forward to the effect of the introduction of KUSANAGI.

Comment from Tomomitsu Misawa, managing director of IBM Japan / Director-General of IBM Cloud
