Have you ever had one of those moments: Elasticsearch is crashing, logs are filling up too fast, or a deployment needs data from three different APIs. The big enterprise solutions aren’t quite right, and your team estimates six months to build something proper. But you know that with Python and a few choice libraries, you could hack something together by tomorrow.
Building AI-powered developer tools comes with unique challenges, and now that we’ve launched our REST API, we want to share some lessons we’ve learned building Pulumi Copilot, an AI assistant for cloud infrastructure.
One of the big challenges was determining what ‘working’ really meant. So when a message landed in our feedback channel after months of rigorous testing - ‘Your tool doesn’t know anything!’ - it caused some mild panic. We’d just made some changes, so we braced for the worst. But our evals were still looking strong, so what was going on?
If a computer can be connected to the internet, someone has tried to run a container on it. From quantum computers to smart toasters, from phones in AWS racks to CI pipelines, there’s many ways to deploy containers. While most people only know about the mainstream cloud providers at the surface, there’s actually a vast world of increasingly unusual and specialized options beneath.
This guide serves two purposes: to showcase the surprising breadth of container options available today, and to help you understand the full spectrum of choices – from practical to very experimental. Whether you’re looking for production-ready solutions or just curious about what’s out there in the dark depths, you’ll find something interesting here.
Continuing our work to bring the best of modern Python to Infrastructure as Code, we are excited to announce built-in support for uv in Pulumi. uv is an extremely fast Python package manager that can install dependencies up to 100x faster than traditional tools, providing one of the fastest ways to manage your Python dependencies and virtual environments.
Building an EKS cluster requires choosing how your containers will actually run - either on EC2 instances you manage or through AWS Fargate’s pod-by-pod approach. The differences can be pretty dramatic in practice. I’m setting up a demo cluster right now using Pulumi, so let me show you what I mean.
Here is my Fargate cluster:
When should you use Cosmos DB on Azure? It’s a hard question to answer.
Azure Cosmos DB tries to do it all - which makes it both powerful and, honestly, kind of confusing. The marketing doesn’t help either. Yeah, it’s a flexible database, but before you jump in, you need to understand how it actually works under the hood, what it’ll cost you, and what trade-offs you’re making by choosing it.
I’m going to break all that down. Here’s a roadmap:
