The Elephant in the Architecture
We, and our colleagues, are often called on to perform architectural assessments for our clients. When we do this, the architects involved with these systems will talk about the performance of these systems, how resilient they are to faults, and how they are designed to evolve to easily support new capabilities. The elephant that rarely comes up, however, is how different systems contribute to bus
Why Cloudflare Chose AMD EPYC for Gen X Servers
Looking back at this week's posts on the design, specifications, and performance of Cloudflare’s Gen X servers using AMD CPUs. Every server can run every service. This architectural decision has helped us achieve higher efficiency across the Cloudflare network.
Gen X Performance Tuning
We have partnered with AMD to get the best performance out of this processor and today, we are highlighting our tuning efforts that led to additional performance across our entire Gen X fleet of servers powered by the 2nd Gen AMD EPYC 7642.
An EPYC trip to Rome: AMD is Cloudflare's 10th-generation Edge server CPU
As we looked at production ready systems to power our Gen X solution, we’re moving on from Gen 9's 48-core setup of dual socket Intel Xeon Platinum 6162's to a 48-core single socket AMD EPYC 7642.

Stuff The Internet Says On Scalability For January 24th, 2020 - High Scalability -
Wake up! It's HighScalability time: Instead of turning every car into rolling sensor studded supercomputers, roads could be festooned with stationary edge command and control pods for offloading compute, sensing and managing traffic. Cars become mostly remote controlled pleasure palaces. Solves compute, latency, and interop. Do you like this sort of Stuff? Your support on Patreon is appreciated mo

Scaling Mobile Development by Treating Apps as Services - Shopify
Scaling development without slowing down the delivery speed of new features is a problem that companies face when they grow. Speed can be achieved through better tooling, but the bigger the teams and projects, the more tooling they need. When projects and teams use different tools to solve similar problems, it gets harder for tooling teams to create one solution that works for everybody. Additiona
The Mythical Mythical Man-Month — Smashing Magazine
How do you move faster when adding folks to a project supposedly slows it down? Mailchimp’s CPO takes the reader through some considerations for preserving momentum while scaling up. Software is difficult to build with lots of complex interdependencies. And everyone needs to work together to get it done. As you work to manage dependencies and introduce tools to help scale, make sure you clearly co
