CloudPanel Server Architecture

Users need to understand CloudPanel's default architecture. It will contextualize how alternative web servers might fit into their deployment.

Default CloudPanel Web Server Configuration

CloudPanel's default technology stack includes:

Component	Version	Role
Nginx	1.21+ with PageSpeed	Primary web server handling HTTP requests
PHP-FPM	7.1-8.1 (configurable)	Processing PHP applications
MySQL/MariaDB	MySQL 8.0 / MariaDB 10.6-10.7	Database management
Redis	6.0+	Optional object caching

This LEMP stack delivers excellent performance for most applications. The Nginx configuration comes pre-optimized for common use cases. It makes it a solid default choice.

How CloudPanel Processes Requests

In the standard CloudPanel deployment, the request flow follows this pattern:

• Client requests reach Nginx first.

• Nginx serves static content.

• Dynamic content (PHP) passes to PHP-FPM.

• MySQL/MariaDB processes database queries.

• The response assembles and returns to the client.

This architecture performs for most websites and applications. But specific use cases may enjoy alternative web servers.

When to Consider Alternative Web Servers For CloudPanel

CloudPanel's Nginx setup works well for most deployments. But there are specific scenarios where LiteSpeed or Apache might be preferable:

Application-Specific Requirements

• Apache dependency: Applications built for or requiring Apache modules.

• .htaccess functionality: Sites relying on directory-level configuration through .htaccess.

• mod_rewrite specifics: Applications using advanced Apache rewrite rules.

Performance Optimization Scenarios

• High-traffic sites: LiteSpeed's event-driven architecture and integrated caching shine under heavy loads.

• Resource-constrained environments: Making the most of limited CPU and RAM resources.

• WordPress acceleration: Sites that would enjoy LiteSpeed's purpose-built LSCache.

Migration Considerations

• Existing Apache setups: Minimizing configuration changes when migrating to CloudPanel.

• Hosting provider transitions: Maintaining consistency when switching infrastructure.

• Legacy application support: Ensuring compatibility with older codebases.

Note: Verify that the performance tuning of the default setup addresses your needs. Do this before switching from Nginx. Nginx often performs with proper configuration adjustments.

LiteSpeed Web Server: Features and CloudPanel Integration

LiteSpeed is a commercial web server designed as a drop-in replacement for Apache. It is popular among high-traffic websites.
