By Cheng Xie , Bryan Shultz , and Christine Xu In a previous blog post , we described how Netflix uses eBPF to capture TCP flow logs at scale for enhanced network insights. In this post, we delve deeper into how Netflix solved a core problem: accurately attributing flow IP addresses to workload identities. A BriefRecap FlowExporter is a sidecar that runs alongside all Netflix workloads.

Modern applications rely on distributed databases to handle massive amounts of data and scale seamlessly across multiple nodes. While sharding helps distribute the load, it also introduces a major challenge cross-shard joins and data movement, which can significantly impact performance.

On April 22, 2022, I received an out-of-the-blue text from Sam Altman inquiring about the possibility of training GPT-4 on OReilly books. We had a call a few days later to discuss the possibility. As I recall our conversation, I told Sam I was intrigued, but with reservations. I explained to him that we could only license our data if they had some mechanism for tracking usage and compensating authors.

As someone who works closely with distributed systems and microservices, I've seen firsthand how complex things can get once Kubernetes, Istio, and service meshes enter the picture. The shift to a cloud-native world is exciting, but it brings new challenges especially around resilience. We can't just hope things wont fail because they will. Thats where chaos engineering comes in.

It almost sounds pejorative, doesnt it? But the distinction between senior and junior software developers is built into our jobs and job titles. Whether we call it entry-level or something else, we distinguish between people who are just starting their careers and those who have been around for a while. Were all still learning (one hopes), but entry-level people are still learning the basics, and seniors have greater responsibility, along with the potential for making bigger mistakes.

Almost daily, teams have requests for new toolsfor database management, CI/CD, security, and collaborationto address specific needs. Increasingly, those tools involve AI capabilities to potentially boost productivity and automate routine tasks. But proliferating tools across different teams for different uses can also balloon costs, introduce operational inefficiency, increase complexity, and actually break collaboration.

Imagine a scenario: You are working at breakneck speed to roll out a new IT product or a business-critical update, but quality control workflows lack efficiency. They are mainly manual and performed late in the development cycle. This challenges your ability to cope with pressing deadlines, innovate, and remain competitive, as manual efforts are slow, workflows lack fast and continuous feedback loops, and critical and major issues arise just before the release.

Kubernetes is becoming a popular choice for running containerized applications. While the core idea is to have a single container running the application in a Pod, there are many cases where one or more containers need to run alongside the application container, such as containers for capturing logs, metrics, etc.

PostgreSQL is, without a doubt, one of the most popular open source databases in the world. Why? Well, there are many reasons, but if I had to pick just one, I’d say its extensibility. PostgreSQL isnt just a database; its an ecosystem of extensions that can transform it to tackle any upcoming challenges.

CPU cores have become significantly wider over the past decade. Ten years ago, the highest-performance CPUs could decode only up to four instructions simultaneously and execute up to eight instructions. However, top-tier CPUs released in recent years have grown to nearly twice this width. For example, Apple’s M4 processor , released in 2024, can decode 10 instructions simultaneously and execute up to 19 instructions.
