Migrating from AWS to Vercel: 10x Developer Velocity for Solo Founders

The Problem

Pablo's experience at Amazon AWS gave him deep expertise in cloud infrastructure, but that expertise also revealed a counterintuitive truth: AWS is terrible for solo founders building consumer products. The AWS ecosystem is designed for large engineering teams with dedicated DevOps resources — it offers unparalleled flexibility and control, but at the cost of enormous complexity. Deploying a simple web application on AWS requires configuring EC2 instances (or ECS/Fargate containers), setting up load balancers, configuring CloudFront CDN, managing Route 53 DNS, setting up RDS databases with read replicas, configuring IAM roles and security groups, setting up CloudWatch monitoring, and dozens of other services — each with its own pricing model, configuration syntax, and failure modes. For Blossend's initial deployment on AWS, Pablo estimated he spent 40% of his engineering time on infrastructure management rather than product development. Every deployment required a multi-step process involving Docker builds, container registry pushes, service updates, and health check verification. A simple code change that took 5 minutes to write could take 30-45 minutes to deploy. The monthly AWS bill for running OpenMyPro's initial version — a relatively simple Next.js application with a PostgreSQL database — was approximately $1,200/month, with costs unpredictable due to the pay-per-resource pricing model. For a bootstrapped startup trying to reach breakeven on $65K total investment, $14,400 per year on infrastructure alone was unsustainable.

Results

The migration from AWS to Vercel + Supabase produced transformative results across every metric. Developer velocity increased approximately 10x, measured by the number of production deployments per week: from 2-3 deployments per week on AWS (limited by the deployment complexity) to 20-30 deployments per week on Vercel (where every git push automatically deploys to a preview URL, and merging to main deploys to production in 45 seconds). Infrastructure costs dropped 85%, from $1,200/month on AWS to approximately $175/month on Vercel Pro + Supabase Pro — saving over $12,000 annually that was redirected to product development. The infrastructure management overhead dropped from 40% of engineering time to approximately 5%, freeing up an estimated 14 additional hours per week for feature development. Performance actually improved post-migration: Vercel's edge network delivered the Next.js application from nodes closer to users, reducing average page load time from 2.1 seconds to 0.8 seconds. Supabase's connection pooling and managed PostgreSQL handled the database workload more efficiently than the self-managed RDS instance. The migration experience also became a compelling talking point in the Blossend narrative — Pablo's unique perspective as someone who built AWS services and then chose not to use them for his own startup resonated strongly with technical audiences and investors who appreciated the nuanced infrastructure decision-making.
