Enterprise readiness and multisite
The Drupal vs WordPress for enterprise question has a clear directional answer. WordPress, with the right architecture, operates at mission-critical scale.
NASA: The definitive stress test
At rtCamp, we have carried out migrations from Drupal to WordPress for hundreds of enterprise clients.
NASA’s migration to WordPress confirmed what we have seen across those engagements. The flagship nasa.gov launch involved 68,698 migrated pages and 104,525 media assets. During the April 2024 eclipse, it absorbed one billion requests in four and a half hours while continuing to stay performant.
WordPress Multisite scales to thousands
WordPress Multisite operates on a single codebase with per-site database isolation. Plugin updates and security patches deploy once and propagate instantly. WordPress VIP supports 1,000+ multisite instances.
Harvard’s WordPress network powers over 2,000 sites serving 9,000+ users. Anyone with a harvard.edu email launches a site in minutes while IT maintains centralized patching. News Corp Australia moved 90+ brands to WordPress VIP, reducing publishing time from 10 minutes to 3 minutes.
Drupal Multisite, a distant second
The Belgian Federal Police, the largest documented Drupal multisite, runs 180+ websites. The implementation required multiple architectural iterations: an initial Aegir-based setup was abandoned because full release cycles took three days. The replacement still required 2–3 hours for parallelized database updates.
WordPress VIP handles the complexity
WordPress VIP packages scaling, CDN, monitoring, CI/CD, and security into a single platform starting at ~$25,000/year. Acquia’s enterprise tiers run ~$100,000/year, with Site Factory at $123,000–$394,000/year.
Engineering teams at rtCamp have successfully built enterprise WordPress solutions for several Fortune 500 firms and government agencies on this infrastructure.
Migrations trend in one direction
Capgemini moved from Drupal to WordPress VIP: 20,000+ pages in 10+ languages across 38 sites. Their Drupal system had 4 webmasters; WordPress enabled 70 people across 40 markets to manage content independently. Travelopia (26 brands) left Drupal because developer dependency had bottlenecked 100+ marketers.
Documented enterprise WordPress-to-Drupal migrations are exceptionally rare.
Key takeaway
🏆 WordPress wins on enterprise scale and multisite. NASA’s billion-request benchmark, Harvard’s 2,000+ sites, and WordPress VIP’s Kubernetes infrastructure demonstrate proven readiness at lower cost.Where Drupal holds ground: Higher education (71–80% of top 100 universities) and Gartner-recognized DXP status through Acquia.
