Wanelo


Wanelo, the 2013 Crunchies award winner for Best E-Commerce Application, brings stores, products and people together in an ad-free online community for shopping. Their user base has grown dramatically in the past year, and the Wanelo “Save” button is popping up next to the Twitter and Pinterest share buttons on large retail sites like Urban Outfitters and the mobile site for Rag & Bone among others. With the help of Fastly, Wanelo improved mobile performance, cut response times and achieved a 98% cache hit rate while scaling 1000% in users in just a year.

Wanelo achieves 98% cache hit rate while growing user base by millions

Challenges


When Wanelo's user base began to grow, they needed a way to scale their original Java platform quickly and efficiently. An image-rich site with infinite scroll and a large mobile user base, the ability to serve images quickly and provide a smooth, speedy experience was critical. Additionally, as large etailers added the Wanelo “Save” button to their sites, they needed a way to ensure that unexpected spikes in requests wouldn't strain their origin servers and compromise performance.

Solutions


While Wanelo architected a new platform from scratch, the company put Fastly in front of their original platform to accelerate performance and free up critical engineering time. Since the site is image-heavy, it made sense to put Fastly in front of Wanelo's S3 image cache for faster delivery to users.


Wanelo also uses Fastly to accelerate API calls like their “Trending Feed” — a scrolling list of product images accessible by their entire user base. This allows them to deliver a smooth, snappy experience, particularly for mobile users, who account for 80% of their user base.


Wanelo utilizes Fastly's Instant Purge feature along with surrogate keys in Varnish to customize caching requests and quickly update related content across the site. For example, by tagging all of the saved products in a user's profile grid with a surrogate key, Wanelo is able to instantly expire all pages of saved products with a single API call whenever a user saves a new product.


Wanelo serves their “Save” buttons directly through Fastly, using Origin Shield and request collapsing features to protect their servers when large ecommerce sites add the button and requests go through the roof.

Results


As more and more retailers add the “Save” button to their websites, Wanelo can rest easy knowing that a large spike in requests won't take the site down because those buttons are served through Fastly.


With Fastly in front of Wanelo's image cache, they are able to efficiently serve tens of thousands of images per second. Implementing Fastly caching in Europe and Australia, resulted in significant performance improvements for international users (who previously were being served images from the US). Ultimately, Wanelo has achieved a cache hit ratio of 98%, both offloading their origin servers and decreasing response times.


Using Fastly to speed up API calls has resulted in a “significantly faster” experience for Wanelo's mobile users, who constitute a significant portion of their active user base.


"By using Fastly in front of the whole Java platform, we were able to scale the older platform without really touching the source code and sustain the growth while simultaneously rebuilding. Without a CDN like Fastly,we would not have been able to work as quickly or efficiently."

"If we weren't on Fastly, we would not be able to cache APIs easily. API is an integral part of almost all mobile applications. If you're not caching it in your mobile app, then you're sacrificing performance unnecessarily."

Konstantin Gredeskoul
CTO



"We know that we can route more API calls through Fastly if needed, and we can do a lot of tweaking using the VCL language to optimize some of those requests without changing the code. Fastly introduced us to the power and flexibility of Varnish. That's a big advantage we didn't necessarily anticipate, and it's a welcomed one!"

Konstantin Gredeskoul
CTO



"Our users expect speed and performance. With older CDNs like Akamai, a lot of times it can take hours to expire. We use Fastly for image and API caching because our users expect the experience to be fast. Once you go Fastly, you can never go back. Why bother if you can do it so fast?"

Konstantin Gredeskoul
CTO



"We wouldn't necessarily be where we are today with application performance if we used a different CDN. The flexibility of Varnish gives us unprecedented control over caching requests and the flow of the data, and it allows us to handpick what we want to cache, and exactly how we do it."
