5 Jev use cases for analytics, with real queries and datasets
Cloud is regional. (Yes, I know, they literally have regions 🙈 I mean the providers.) I ran 650k data job ads through Jev with one question: which cloud is this job's stack built on? Europe hires for Azure: 50% of the ads that name one cloud. The US hires for AWS: 50% as well. A few fun ones: - Berlin leans AWS (40%) while Germany as a whole is 54% Azure - Virginia, home of us-east-1: 77% AWS - Arkansas: 76% Google Cloud - Spain is the only big European market where AWS wins Job ads are an imperfect proxy ofc Some name several clouds (I dropped those), and there are a few false positives. Still, it matches what I see in my own network. WDYT? Does it match where you work?
