The men’s ready-to-wear brand Celio is present through 1,500 points of sale in nearly 50 countries, on all continents. The e-commerce platform was created in 2009. Digital is obviously strategic for Celio, which has been relying on Fasterize as a “ next generation ” CDN since 2015, for a site that is both stable and fast.

Fasterize’s CDN, an essential building block in Celio.com’s technical stack

All Celio.com traffic and resources go through Fasterize, in order to ensure both the loading speed of web pages and the stability of its infrastructure. Our Frontend Optimization engine has become indispensable for Celio.com’s infrastructure!

To bring content closer to its users around the world and improve its loading speed, Celio had previously identified CDN solutions , but Fasterize caught the IT teams’ attention. Indeed, its “ next generation CDN ” dimension allows both to guarantee the availability of the site and to ensure the automation of Frontend optimizations, all for a more advantageous budget .

This saves technical teams time because they no longer need to redo optimizations for each modification on the site. Fasterize allows you to intelligently and sustainably automate good webperf practices and techniques without requiring resources!

Furthermore, 40% of Celio.com’s traffic comes from mobile, and tablets are available to customers in store (i.e. a captive audience on the verge of making a purchase, and which should not be lost due to a poor user experience when they are so close to the goal). However, although the business stakes are always higher as mobile usage grows, a mobile site remains more difficult to optimize due to the power of processors and more random network conditions. Thanks to Fasterize’s optimizations, pages are displayed quickly, even on mobile, in particular thanks to the intelligent cache system and image optimization .

Rapid deployment and immediate results that last over time

After a test of Fasterize on the Indian catalog, the solution was deployed in less than 8 weeks on the new version of Celio.com. The result was immediate and clear: a Speed ​​Index optimized by 40%!

The effects are beneficial for the business, the availability and security of the merchant platform, and it also helps relieve the IT teams who rely 100% on the Fasterize engine.

With each successive redesign, improving web performance remains a priority for Celio’s technical teams, whose goal is to get closer to the business in order to evangelize on web performance. The site is set to integrate more and more customization, and Fasterize’s SmartCache allows Celio.com to keep a secure, stable and efficient site despite the integration of dynamic content .

An engine and a human

In addition to the CDN, the advanced caching system and image optimization features such as lazyloading , what is also very important to Celio is the relationship of trust established with Fasterize experts. From the very first tests to the evolutions of the site, Celio’s technical teams have always benefited from unwavering support and expert advice to get the most out of the platform.

On a daily basis, production teams use the dashboard directly and can call on their dedicated Customer Success Engineer for more advanced settings, and thus improve their skills.

In short, the issues of speed and availability are fully addressed by Fasterize, which is one less thing to worry about for Celio’s IT department, which can concentrate on its core business with complete peace of mind, even during peak loads .
