How we 30x’d our Node parallelism

What’s the best way to safely increase parallelism in a production Node service? That’s a question my team needed to answer a couple of months ago. We were running 4,000 Node containers (or ‘workers’) for our bank integration service.

Serving 100µs reads with 100% availability

This is the story of how we built ctlstore, a distributed multi-tenant data store that features effectively infinite read scalability, serves queries in 100µs, and can withstand the failure of any component. Highly-reliable systems need highly-reliable data sources. Segment’s stream processing pipeline is no different.

Making the LinkedIn experimentation engine 20x faster

At LinkedIn, we like to say that experimentation is in our blood because no production release at the company happens without experimentation; by “experimentation,” we typically mean “A/B testing.” The company relies on employees to make decisions by analyzing data. Experimentation is a data-driven foundation of the decision-making process, which helps with measuring the precise impact of every change and release, and evaluating whether expectations meet reality.

2020 Cloud Report

Read the 2020 Cloud Report from Cockroach Labs, and learn which cloud platform performs best for transactional workloads across TPC-C, Network Throughput, CPU, and Storage benchmarks. If there’s one thing we’ve learned in our three years of benchmarking cloud providers on transactional workloads, it’s this: the results change often. Last year’s report showed AWS dramatically outperforming GCP across TPC-C performance, CPU, Network, and even cost.

How the Internet Spans the Globe

Undersea cables are responsible for moving data between countries and continents at high speeds, making everything from photo sharing to financial transactions possible. These cables use fiber optics to move data at high speeds to land, where the data is then conveyed via fiber optics to homes and businesses. Yet, despite the billions of people relying on the data moved by undersea cables, there are only about 380 of them worldwide as of 2019, according to CNN estimates, though they span more than 745,000 miles—or more than three times the distance to the moon.
