LinkedIn has become a place of AI generated posts with AI generated responses to said posts.

What do you want the world to know about you? What's the brand you're building? For example: I'm a DevOps Engineer who also brings strong AppSec/DevSecOps and Cloud Engineering chops to the table. The problem is that if you do "a little bit of everything", no one knows what to

Definitely a cool thing to get this month 😎 Datadog reached out to me about the program last month and I'm excited to join. I've always said that there are two ways to implement monitoring and observability: 1. Homegrown (open-source tools together) 2. Enterprise (something

I've been building a lot of what I'll call "k8s management clusters" lately. And it makes sense because you always need a method for originating the deployments. For example, you want to use ArgoCD for all of your deployments and to confirm that the current state is the desired

I always get something like this when I ask chatgpt to create an image for me... And it never actually creates it lol. But don't worry everyone, AI is going to take over soon!

Kubernetes Security in a nutshell: ✅ Namespace isolation ✅ SecurityContexts ✅ Network Policies ✅ Service and Pod encryption And they're all connected. Namespaces are a great way to logically isolate workloads, but by default, those workloads can still talk to each other as

I love when I'm looking up how to do something and one of the first results is a video I made 3 years ago.

AWS EKS has two options: ✅ EKS with Fargate ✅ EKS with ec2 instances The biggest difference, conceptually, is that Kubernetes Worker Nodes are either “Serverless” or ec2 instances. From a performance and scalability perspective, both work well. The biggest difference is

It's been a while since I've done this! Testing out some AD configurations for a legacy application that requires on-prem Active Directory.

In any technical role, you must sell the idea of "you". Whether it's an architecture you came up with, a new feature in an app, or a new tool to implement. You have to sell the idea of why it's important, and the majority of the time, that means selling "you". I break it all

Every blog post/doc I've seen for implementing Karpenter on EKS is never complete. They either don't show how to set up the IAM Role or the permissions, or the actual installation and configuration of Karpenter itself. I put together a comprehensive guide, from start to finish,

Are there any conferences in the DevOps/Cloud-Native realm that are actually about the engineering anymore? Asking for a friend... the friend is me... I don't want to sit through buzz/hype sessions anymore.

Weekend project. Diving into Django 🤓 What are you working toward this weekend? #kubernetes #devops #platformengineering

Django (Python framework) runs A LOT of the internet. Here's a simple Django app breakdown: ✅ Import all built-in Django tooling (Django is known for the out-of-the-box experience) ✅ Import Models (Python configs that build the database. This is where ORM comes in) ✅ Set the

Do you think about the best place to deploy containerized workloads? Based on what you're deploying, maybe it should be AKS. On the other hand, maybe it could be a container orchestration service like AWS ECS. If so, I built a tool and made it free to help you figure this
