Website Architectures Explained: SSG, CMS, Frameworks, Hosting and Deployment Options Compared
The modern web offers more ways to build and deploy websites than ever before.
A decade ago, most websites were powered by traditional content management systems such as WordPress running on shared hosting. Today, developers can choose from static site generators, modern JavaScript frameworks, headless CMS platforms, cloud deployment services, VPS servers, serverless infrastructure, and edge computing platforms.
As a result, one of the most common questions website owners ask is no longer “How do I build a website?” but rather: what architecture should I choose?
The answer depends on your goals, technical skills, budget, content strategy, and scalability requirements.
This guide explains the major categories of website architectures and deployment models, compares their strengths and weaknesses, and helps you figure out which approach works best for different types of websites.
Understanding Website Architecture
Website architecture is more than just the framework.
Many people assume it refers only to the framework powering a website, but a complete website architecture consists of multiple layers.
A simplified architecture can be represented as:
Content Layer
↓
Framework / CMS
↓
Rendering Method
↓
Hosting Platform
↓
CDN / Delivery NetworkFor example:
Markdown
↓
Astro
↓
Static HTML
↓
Cloudflare Pages
↓
Cloudflare CDNOr:
WordPress Editor
↓
WordPress CMS
↓
PHP Rendering
↓
VPS Server
↓
Nginx
↓
VisitorsUnderstanding these layers makes it easier to evaluate modern website stacks.
Major Types of Website Architectures
Most websites today fall into four major architectural categories.
1. Static Site Generators (SSG)
Static Site Generators create HTML files during the build process.
Instead of generating pages when a visitor arrives, pages are pre-generated and delivered instantly.
Popular examples include:
- Astro
- Hugo
- Eleventy
- Jekyll
- Gatsby
