As expected, clickbait content for a clickbait title. I can understand CF pains, I went to terraform a long time ago and never looked back. Elasticache is definitely outrageously priced. I can’t imagine a context where I would choose it over a simple instance with redis.
But the others, it’s more like incompetent use and/or poor development process. Sorry, but it’s not a tools’ job to prevent stupidity.
