One of our large scale data infrastructure challenges here at Cloudflare is around providing HTTP traffic analytics to our customers. HTTP Analytics is available to all our customers via two options:
One of my favorite Amazon Leadership Principles is Customer Obsession. When we launched AWS Lambda, we focused on giving developers a secure serverless experience so that they could avoid managing infrastructure. In order to attain the desired level of isolation we used dedicated EC2 instances for each customer. This…
Site Isolation is a security feature in Chrome that offers additional protection against some types of security bugs. It uses Chrome's sandbox to make it harder for untrustworthy websites to access or steal information from your accounts on other websites.
People call WebAssembly a game changer because it makes it possible to run code on the web faster. Some speedups are already present, and some are yet to come. With ...

Bufferbloat is high latency (or lag) that occurs when there’s other traffic on your network. This means that your network isn’t always responsive - it’s wasting your time.
Internally our DDoS mitigation team is sometimes called "the packet droppers". When other teams build exciting products to do smart things with the traffic that passed through our network, we take joy in discovering novel ways of discarding it.
Removing (most of) the software stack from the cloud Clive is an operating system designed to work in distributed and cloud computing environments. It’s main design guidelines are: Ther…

Today we’re open sourcing the FoundationDB Document Layer, a document-oriented database that extends the core functionality of the FoundationDB key-value store.
This paper presents an evaluation of the use of a high-level language (HLL) with garbage collection to implement a monolithic POSIX-style kernel. The goal is to explore if it is reasonable to use an HLL instead of C for such kernels, by examining performance costs, implementation challenges, and programmability and…
