Multisite

Organizations managing multiple websites face a familiar trap: duplicated effort, inconsistent quality, and spiraling costs. A Drupal Multisite platform changes the equation — one shared platform powers every site, while each keeps its own branding, content, and domain. Updates and security patches are applied once and take effect everywhere.

Running multiple websites independently means:

• Duplicated costs — Each site needs its own development, hosting, and maintenance
• Inconsistent quality — Different codebases drift apart over time
• Security risk — Patching dozens of standalone sites is slow and error-prone
• Scaling pain — Going from 5 to 50 sites becomes exponentially expensive
• Accessibility burden — Ensuring EAA compliance individually across every site [9]

A Multisite platform directly addresses these challenges by sharing infrastructure across all sites:

• Central management — One platform for updates, security, and features — eliminating duplicated effort and reducing security risk
• Up to 80% cost reduction — Shared infrastructure dramatically lowers per-site costs, solving the scaling problem
• Consistent quality — Shared components ensure uniform UX and accessibility compliance across all sites
• Rapid scaling — Launch new sites in hours, not weeks — growth without exponential cost
• Custom branding — Each site keeps its own colors, fonts, logos, and design
• Custom domains — Every site on its own domain or subdomain

• Multi-municipality platforms — Several towns on one instance, each with its own identity
• Enterprise multi-brand — e.g. Volkswagen AG InfoPortal: 20+ brand websites managed by one team [3]
• Media multi-site — e.g. Einfachbacken, daskochrezept.de, beebetter.de: multiple content brands on one shared Drupal instance [5]
• Publisher content pools — e.g. Wirtschaftsverlag: 30+ satellite sites fed from one central content pool [6]
• Franchise networks — Individual location sites with corporate consistency
• Department microsites — Universities or governments with dozens of sub-sites
