Cloudflare has been building a micro-AWS/Vercel competitor and I love it; i.e., serverless functions, queues, sqlite, kv store, object store (R2), etc.
I would love to see a good blog post or article on Cloudflares KV store. I just checked it out, and it reports eventual consistency, so it sounds like it might be based upon CRDTs, but I'm just guessing.
Vercel doesn't offer any of that, without major caveats (e.g. must use Next.js to get a serverless endpoint). And to the degree they do offer any of it, it's mostly built on infrastructure of other companies, including Cloudflare.
Cloudflare is just reimplementing every service that Akamai has had for 10 years. The only difference is Cloudflare is going after the <$100/mo customer.
