Technical notes and the occasional detour — AWS, serverless, Terraform, Python, AI in software, and life from Costa Rica.
A sourced comparison of the two default choices for managed authentication — real pricing at 10k, 50k, and 100k users, the pros and cons of each, the lock-in nobody mentions, and why building your own login is a permanent job.
