Right, which is why they only executed a partial migration for certain workloads that make sense: https://blog.twitter.com/engineering/en_us/topics/infrastruc...

I think what really irks me is this meme that “obviously they have massive infrastructure waste.”

Does anyone have credible evidence that there is enormous waste in Twitter’s infrastructure? Just because Musk says “cut $1b in infra spending” doesn’t mean that there is $1b of things to cut, just lying about being wasted. Some of the smartest minds in our industry work/worked at Twitter. Are they that bad at their jobs?

What is actually going to happen is this: they’ll turn off all of their data warehousing stuff, blinding the business. They’ll cut their redundancies and backups, reducing the probability that they can do effective DR. They’ll reduce spending on observability so far that they won’t even know what’s going wrong (it’s surprisingly expensive). And that’ll get them to the $1b in cuts - by flying blind (both in a business sense, and a technical sense), and just hoping they don’t need to recover from a disaster.
