Seamlessly Swapping the API backend of the Netflix Android app

The Netflix TechBlog

SEPTEMBER 8, 2020

This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI. Functional Testing Functional testing was the most straightforward of them all: a set of tests alongside each path exercised it against the old and new endpoints.

With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Compressing, minifying and caching assets. We can compress our assets, minify our styles and scripts, and cache things responsibly so we’re serving what the user needs in the most efficient way possible.

A Decade of Dynamo: Powering the next wave of high-performance, internet-scale applications

All Things Distributed

OCTOBER 2, 2017

With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.

A persistent problem: managing pointers in NVM

The Morning Paper

DECEMBER 8, 2019

Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. The beauty of persistent memory is that we can use memory layouts for persistent data (with some considerations for volatile caches etc. What about security?

Scaling Amazon ElastiCache for Redis with Online Cluster Resizing

All Things Distributed

NOVEMBER 21, 2017

Redis's microsecond latency has made it a de facto choice for caching. With online cluster resizing, our goal was to design a fully managed experience for cluster resharding, which would support both scale-out and scale-in and retain open source compatibility.
