Next.js Hosting Guide: Server-Side Rendering, Static Generation, and Infrastructure Requirements

Understanding Next.js Rendering Modes

Next.js supports three primary rendering strategies:

• Static Site Generation (SSG): Pages pre-rendered at build time, served as static HTML
• Server-Side Rendering (SSR): Pages rendered on each request, requires Node.js server
• Incremental Static Regeneration (ISR): Static pages with periodic revalidation

Deployment Options

Option 1: Vercel (Zero-Config)

Vercel offers the smoothest deployment. Run `vercel` and get automatic edge caching, serverless functions for API routes, ISR revalidation, automatic HTTPS, and global CDN. Free tier: 100GB bandwidth. Pro: 1TB bandwidth.

Use Vercel when you want zero infrastructure management, your site is primarily static or uses ISR, you need edge caching and global distribution. Avoid for heavy SSR workload or complex background jobs.

Option 2: Self-Hosted on VPS

For static export only, build with `npm run build` and serve with Nginx. For SSR/ISR, run Next.js as Node.js server with PM2 process management and Nginx reverse proxy.

Server requirements: 2GB RAM minimum for small sites, 4-8GB RAM for moderate traffic (10k-50k daily visitors), 16GB+ RAM for high-traffic SSR (100k+ daily visitors).

Option 3: Docker Containers

Containerize Next.js for Kubernetes, AWS ECS, or Docker Swarm. Enable standalone mode in next.config.js for smaller images. Use when already using container orchestration or need horizontal auto-scaling.

Option 4: Static Hosting with CDN

For SSG-only sites, use Cloudflare Pages or Netlify. Both offer generous free tiers, global CDN distribution, automatic HTTPS, and preview deployments.

Optimizing Next.js Performance

Image Optimization

Next.js Image component requires either Vercel (built-in) or self-hosted configuration with Cloudflare Images or custom loader for external CDN.

Caching Strategies

Cache static pages for 1 year with immutable assets. For ISR pages, cache at CDN with short TTL and let Next.js handle revalidation. For API routes, implement Redis caching.

Cost Comparison

For a site with 100k monthly visitors:

• Vercel Pro: ~$20/month (fits in 1TB bandwidth)
• Self-hosted VPS (4GB RAM): $24-40/month including server, bandwidth, backups
• Dedicated server (high-traffic SSR): $100-300/month, needed at 500k+ visitors
• Cloudflare Pages (static only): Free for most use cases

Which Hosting Option Should You Choose?

For most projects, start with Vercel. The free tier handles small sites, and Pro ($20/month) is competitive for medium traffic. For cost-conscious high-traffic SSR, self-host on a dedicated server. Purely static sites work well on Cloudflare Pages. For complex enterprise deployments, use Kubernetes.
