How we migrated Dropbox from Nginx to Envoy
In this blogpost we’ll talk about the old Nginx-based traffic infrastructure, its pain points, and the benefits we gained by migrating to Envoy. We’ll compare Nginx to Envoy across many software engineering and operational dimensions. We’ll also briefly touch on the migration process, its current state, and some of the problems encountered on the way. When we moved most of Dropbox traffic to Envoy

Async IO in Rust (part III)
This is the third article in series of articles about the design of Rotor, a library doing asynchronous IO in Rust. It has been about three months since my first article was published. And my first asynchronous code written in rust is almost a year old. That code still works in production (in a non-mission-critical role). This is to say that it’s time to stop rewriting rotor on every occasion and

Scaling with Queues
Our home-grown geo-distributed architecture based CDN allows us to delivery dynamic javascript content with minimum latencies possible. Using the same architecture we do data acquisition as well. Over the years we've done a lot of changes to our backend, this post talks about some scaling and reliability aspects and our recent work on making fast and reliable data acquisition system using message
Nginx image processing server with OpenResty and Lua
Posted September 20, 2013 by leafo (@moonscript) · Tags: openresty Today I'll be showing you how to create a fast on the fly image processing server. The whole system can be created in less than 100 lines of code. We'll be using OpenResty, an enhanced distribution of Nginx. We'll also need to write a little bit of Lua to get all the functionality we want. Lastly, we'll be using this Lua ImageMagic
Scaling CloudFlare's Massive WAF
I first heard John speak at the Nginx.Conf conference in San Francisco. He’s done an amazing job explaining a large scale, high volume WAF (Web Application Firewall) platform that he and his colleagues have built. In this interview he’ll explain design goals, benchmarking, testing and WAF rule new roll outs. The story here is really about performance and scale by optimizing every last drop out wit

How Disqus Went Realtime with 165K Messages Per Second and Less than .2 Seconds Latency - High Scalability -
Here's an Update On Disqus: It's Still About Realtime, But Go Demolishes Python. How do you add realtime functionality to a web scale application? That's what Adam Hitchcock, a Software Engineer at Disqus talks about in an excellent talk: Making DISQUS Realtime (slides). Disqus had to take their commenting system and add realtime capabilities to it. Not something that's easy to do when at the time
Battle ready Nginx - an optimization guide – Blogzor
A guide to optimizing Nginx for maximum performanceMost setup guides for Nginx tell you the basics - apt-get a package, modify a few lines here and there, and you’ve got a web server! And, in most cases, a vanilla nginx install will work just fine for serving your website. However, if you’re REALLY trying to squeeze performance out of nginx, you’ll have to go a few steps further. In this guide, I’
