Scaling Kubernetes to 7,500 Nodes

We’ve scaled Kubernetes clusters to 7,500 nodes, producing a scalable infrastructure for large models like GPT-3, CLIP, and DALL·E, but also for rapid small-scale iterative research such as Scaling Laws for Neural Language Models. Scaling a single Kubernetes cluster to this size is rarely done and requires some special care, but the upside is a simple infrastructure that allows our machine learning research teams to move faster and scale up without changing their code.

Monitoring vs. Observability: Can You Tell The Difference?

Observability has gained a lot of popularity in recent years. Modern DevOps paradigms encourage building robust applications by incorporating automation, Infrastructure as Code, and agile development. To assess the health and “robustness” of IT systems, engineering teams typically use logs, metrics, and traces, which are used by various developer tools to facilitate observability. But what is observability exactly, and how does it differ from monitoring?

AWS DevOps Professional Cheat Sheet

This cheat sheet is a comprehensive version, listen, it will not make any sense without having an idea of what the actual resources on AWS are. I highly suggest you finish a course on DevOps Professional Certification or have 2–3 years of working experience on AWS and get back here.

Fulfilling the promise of CI/CD

CI/CD (continuous integration and Continuous Delivery/Deployment) is part of the fabric of our lives. We go to conferences about CI/CD, we write articles and blog about CI/CD, we list CI/CD on our LinkedIn page. Nobody even debates about whether it’s the right thing to do or not. We are all on the same page. Right?

Basically, bring up those AWS resources like EC2 instances, DBs, etc; and tear them down when you don’t need them; this blog post is something that might be for you.

The Tech Debt Playbook

All software teams have technical debt — parts of the code that weren’t created with today’s challenges in mind, or were written poorly, or were expedient hacks that are now problematic. Having tech debt isn’t necessarily a bad thing; if people spent all their time making code perfect, nothing would ever get done. But too much accumulated debt makes it slower to deliver new features and is a source of bugs and quality issues.

A Deep Dive into Architecting a Kubernetes Infrastructure

Now that justice has been done to clear the clouded thoughts you may have, let us now dive into the next important step in our journey with Kubernetes and the infrastructure as a whole.
