Cloudflare recently detailed how it manages its servers’ egress traffic using “soft-unicast “. Soft-unicast allows multiple servers to share a single IPv4 address for their egress traffic while redirecting the response packets to the correct physical server. It provides a scalable, cost-efficient solution for Cloudflare to offer various products that require tagged egress IP addresses. (Read more on InfoQ)

Sidecars query multiple services concurrently to accomplish this goal and ensure that requests are entirely isolated internally. (Read more on InfoQ)

Slack recently published how it implemented the Circuit Breaker pattern to improve its CI/CD pipeline availability. Before this project, engineers at Slack saw challenges as peak request volumes in internal tooling caused cascade failures in dependent systems. Since completion, engineers saw increased service availability and fewer bad developer experiences like flakiness from failing services. (Read more on InfoQ)

Spotify engineers recently published how they standardized architecture diagrams at the company. They defined a standard system model named the Spotify Software Model and adapted the C4 model to visualize it.
