Same app, two platforms
We deployed the same B2B dashboard on AWS (ECS and CloudFront) and on Vercel and measured for a month.
Latency
p95 was 182 ms on AWS and 164 ms on Vercel. Both are well within budget for a B2B product.
Cost and operations
Vercel was cheaper to operate at low traffic and needed no infrastructure work. AWS made sense once the client needed VPC access to existing databases and strict data residency.
