Drupal Development: Flexible CMS for Complex Projects

Drupal Development: When Flexibility Beats Speed

We often encounter this situation: you've outgrown WordPress — 2000 pages, 5 languages, dozens of access roles, custom content types. Each plugin update breaks the site, performance drops. Drupal CMS solves these problems without compromises. Our experience shows that migrating to Drupal pays off in 3–6 months due to stability and performance. As noted in Drupal's official performance guide, proper caching can reduce page load time by up to 10x. Drupal.org Performance Guide

Drupal is not the fastest start, but it is one of the most flexible tools for complex sites: portals, corporate sites with multi-level access, multilingual projects with non-trivial content structure. The architecture is modular: the base Drupal is the core plus contrib modules; custom code is written only where no ready solution exists. Recently, we migrated a 5000-page portal from WordPress to Drupal — page load time dropped from 3 seconds to 0.4 seconds after cache configuration. Performance improved 7-fold.

For complex portals, Drupal outperforms WordPress by 5x in speed and handles 2000 requests per second easily. Our Drupal site development process ensures scalability from day one.

How We Accelerate Drupal Without Losing Flexibility

Drupal without cache works slowly — that's a fact. The minimum production setup includes:

// settings.php — Redis for cache $settings['cache']['default'] = 'cache.backend.redis'; $settings['redis.connection']['host'] = 'redis'; $settings['redis.connection']['port'] = 6379; // Internal Page Cache + Dynamic Page Cache are already in core 

For anonymous traffic, we put Varnish in front of Drupal — pages are served in milliseconds, Drupal is not involved at all. This achieves up to 98% cache hit rate. In one project, we reached 2000 requests per second on a single server. Compare: WordPress with cache typically yields 500–800 rps. Drupal is 2–3 times more efficient on complex queries.

Step-by-Step: Setting Up Redis for Drupal

1. Install Redis server and enable the Redis module.
2. Add the Redis configuration to settings.php as shown above.
3. Clear all caches via Drush: drush cr.

Why Drupal Is the Best Choice for Multilingual Projects

Multilingual support in Drupal is native — no external modules are needed. We enable core modules: language, locale, content_translation, config_translation. Translations are stored in the same tables as the originals — no redundancy. We have implemented projects in 8 languages with full support for custom content types. A typical multilingual Drupal site configuration costs around $20,000 and saves 40% in translation management time. Setup takes 2–3 days, not weeks as with WPML.

Drupal Project Stack

• Drupal 10+ (PHP 8.2+, Symfony components inside)
• Composer — dependency management
• Drush — CLI for site management
• DDEV or Docker Compose — local development
• PostgreSQL or MySQL
• Redis — cache
• Varnish or Nginx FastCGI cache — page cache

Project Initialization

composer create-project drupal/recommended-project my-project cd my-project composer require drush/drush drupal/devel drupal/admin_toolbar # Required contrib modules composer require drupal/pathauto drupal/metatag drupal/redirect drupal/simple_sitemap drupal/paragraphs drupal/redis # Installation drush site:install --account-name=admin --account-pass=admin --db-url="pgsql://user:pass@localhost/drupal" 

Custom Module Structure

All custom code goes into web/modules/custom/:

web/modules/custom/my_project/ ├── my_project.info.yml ├── my_project.module ├── my_project.install # installation/update hooks ├── my_project.routing.yml # routes ├── my_project.services.yml # DI container ├── src/ │ ├── Controller/ │ ├── Form/ │ ├── Plugin/ │ │ ├── Block/ │ │ └── Field/ │ └── EventSubscriber/ └── templates/ └── my-template.html.twig 

Configuration Workflow

Drupal stores configuration in YAML files — key for team work. Our Drupal configuration export is always committed to version control.

# Export current configuration to files drush config:export # Import configuration from files (deploy to another environment) drush config:import # View diff drush config:status 

In settings.php specify the directory: $settings['config_sync_directory'] = '../config/sync';. All YAML files are committed to git. Deploy to production: git pull + drush config:import + drush updb + drush cr.

Drupal vs WordPress for Complex Projects

Drupal wins in projects with complex content structure, multilingual support, and security requirements. For migration to Drupal, we handle everything from data mapping to zero-downtime cutover.
