One of my big takeaways from this week was the "cattle, not pets" approach to compute resources. It encourages using and configuring servers and containers as easily replaceable units. It aligns with the containerization of test infrastructure that I've seen in industry. Powerful hardware can run multiple instances of isolated containers to make good use of performance advancements. What struck me most is that this isn't just an infrastructure choice — it forces software itself to be written differently, avoiding local state and hardcoded dependencies so any instance can be killed and replaced without issue. I am still learning about docker and its uses but I expect that I'll get more exposure to serverless architectures. I also think the practical implications of scaling to zero are interesting. I'll be reading more about it.
