AWS Auto Scaling Groups 2024-12-30
Today my focus was on starting work on a dynamically built replacement for my project box. Eleven iterations later and I had an auto scalable box which can host vacuum-flask, connect to efs, and talk to redis to maintain session state. After spending most of the day on that, it occurred to me that I might be able to get away with using an “ECS optimized instance” with my newly found user-data experience and sneak vacuum flask in and still have capacity to spare for some cheap ecs tasks.
