In two hours (the same amount of time it takes to binge two episodes of The Witcher) you will build a ride-sharing application with Node.js and CockroachDB. That’s the beauty of this Node.js and CockroachDB fundamentals course just released by Cockroach University: You get real-life, hands on experience with the tools you need to build modern applications. Experience with modern application architectures, and with distributed databases in particular, is becoming a regular requirement for open roles at great companies like Roblox, Accenture, Netflix, Apple, and others. This Node.js course is a quick way to gain the requisite experience so that you can demonstrate your distributed systems skills in an interview.

Kubernetes is an open-source container orchestration platform that allows you to automate running and orchestrating container workloads. It is a powerful tool that offers a huge ecosystem of tools — package managers, service meshes, source plugins, monitoring tools, and more — as an abstraction layer for deploying standardized, full-stack applications across an ever-increasing range of platforms. Kubernetes is often referred to as “K8s.”

When the performance of your SQL database drops suddenly, do you know why? Tracking performance and linking cause to effect can be tricky with real-world database systems. DBAs, architects, and SREs are often working with multiple database systems, each with multiple databases in various states of development, testing, and production. These systems are often mixed between one or more cloud providers and self-hosted servers. On top of that, the performance of each database is influenced by auto-scaling, constantly-shifting workloads, engineering changes and updates, and more!

If you’re a retail business, your current reality may best be described as “challenging” — even as a flood of pent up post-pandemic consumer spending is unleashed. Thanks to Amazon, customers expect abundant product availability, personalized recommendations, competitive pricing, and fast delivery. Mega retailers like Target and Walmart are fighting back by offering expanded online shopping, in-store shopping services with curbside pickup, and local delivery options — some even same-day.

Nubank, a leading Brazilian financial technology company valued at more than $45 billion dollars, needed a scalable SQL database for its critical credit card authorization service. The company initially stored data for this service on-prem using an in-memory data store, but as the business rapidly grew (from 12 million customers in 2019 to 40 million customers in 2021), it needed a more scalable solution that would not rely so much on memory and enable Nubank to keep growing. Nubank’s Authorizer team chose CockroachDB due to its ultra-resilience, simple scalability, strong consistency, and easy maintenance. They set up on-prem CockroachDB deployments and migrated their credit card authorization application.

A few days ago, we (Artem and Chris) were working with two different customers that had the same requirement: they needed to encrypt certain tables in their databases. This is not uncommon. Encryption comes with a slight performance penalty, so many companies prefer not to encrypt their entire database. Instead, the best practice is to encrypt only the tables that contain sensitive information, so less-sensitive data can be accessed without the overhead the encryption creates.

Optimal Systems came to CockroachDB with the best kind of problem: they had become too successful. Optimal was founded in 1991 to meet the European Space Agency’s need to archive its satellite photos. Decades of successful growth saw the storage product they built for the ESA evolve and expand to serve clients in more than 30 countries.

As we outlined in Deploy a Multi-Region Application in Just 3 Steps, we’ve made major changes to simplify the multi-region configuration in CockroachDB. The new abstractions allow users to think of multi-region databases and tables in three ways:

As an SRE on the CockroachDB Dedicated team, we have the unique challenge of monitoring and managing a fleet of CockroachDB clusters around the globe. Perhaps needless to say, as a distributed database, security is an utmost priority for us. To address some of the needs related to security and monitoring (for example intrusion detection audit logging), we’ve invested in our next generation of Security Information and Event Management (SIEM) infrastructure.
