Over the years, 300 million Pinners have saved more than 200 billion Pins on Pinterest across more than 4 billion boards. To serve this vast user base and content pool, we’ve developed thousands of services, ranging from microservices of a handful CPUs to huge monolithic services that occupy a whole VM fleet. There are also various kinds of batch jobs from all kinds of different frameworks, which can be CPU, memory or I/O intensive.

Traefik 2.0The Wait Is Over! When we started our journey toward 2.0, we had high expectations (since you had high expectations), and huddled around the whiteboard. We designed Version 2 as if there were no constraints: we forgot our codebase, put aside technical challenges, and developed a new configuration structure that would welcome everything we had ever dreamed of for Traefik. We forgot what was impossible so we could build it!

In our previous blog posts, we discussed the capabilities and functioning of PostgreSQL Automatic Failover (PAF) by Cluster Labs and Replication Manager (repmgr) by 2ndQuadrant. In the final post of this series, we will review the last solution, Patroni by Zalando, and compare all three at the end so you can determine which high availability framework is best for your PostgreSQL hosting deployment. Patroni originated as a fork of Governor, a project from Compose.

At Lyft, like many other companies, we need to make accurate short and long-term forecasts. Some of the metrics that we need to accurately predict are number of driver hours provided by drivers in different regions — i.e our supply side of the business — and also number of rides taken by riders in different regions, i.e. our demand. We have several internal tools that we use to make forecasts.

An increasing number of organizations are migrating from a datacenter composed of virtual machines (VMs) to a “next-generation” cloud-native platform that is built around container technologies like Docker and Kubernetes. However, due to the inherent complexity of this move, a migration doesn’t happen overnight. Instead, an organisation will typically be running a hybrid multi-infrastructure and multi-platform environment in which applications span both VMs and containers. Beginning a migration at the edge of a system, using functionality provided by a cloud-native API gateway, and working inwards towards the application opens up several strategies to minimize the pain and risk.

In 1997 IBM’s Deep Blue software beat the World Chess Champion Garry Kasparov in a series of six matches. Since then, other programs have beaten human players in games ranging from Jeopardy to Go. Inspired by his loss, Kasparov decided in 2005 to test the success of Human+AI pairs in an online chess tournament.2 He found that the Human+AI team bested the solo human. More surprisingly, he also found that the Human+AI team bested the solo computer, even though the machine outperformed humans.
