Zero-downtime Next.js hosting on AWS

A freelance engagement to take Floxify's Next.js applications to production on AWS.

The apps needed to be highly available, served securely across subdomains, and updated without taking the site down on every release.

1. 01

   Host on EC2

   Deployed the Next.js apps on AWS EC2 with high availability and performance in mind.

2. 02

   Nginx at the edge

   Configured Nginx as a reverse proxy for subdomain management, HTTPS (SSL/TLS) enforcement and DNS routing.

3. 03

   Zero-downtime restarts

   Used PM2 process clustering for zero-downtime restarts and efficient resource use.

4. 04

   Automate releases

   Automated CI/CD with GitHub Actions and self-hosted runners.

5. 05

   Harden

   Applied security best practices: firewalls, IAM roles and performance monitoring.

Simplified view of how the pieces connect.

• Zero-downtime restarts with PM2 clustering
• HTTPS enforced across subdomains via Nginx
• Automated deploys through GitHub Actions
