Overview
KUSANAGI 9 for AWS is a performance-optimized WordPress and CMS platform designed specifically for AWS, providing a pre-configured, production-ready environment that simplifies deployment while maintaining operational consistency.
Operational Standardization
KUSANAGI emphasizes operational efficiency through its unified KUSANAGI commands, enabling teams to automate and standardize common infrastructure and application tasks:
- Environment Provisioning: Quickly deploy new environments using consistent, predefined configurations.
- Middleware Switching: Seamlessly switch between Nginx and Apache depending on workload or operational requirements.
- Certificate Management: Automate SSL/TLS setup and renewal using Let's Encrypt.
This command-driven workflow helps reduce configuration drift, minimize manual errors, and maintain consistency across multiple projects and teams.
Secure Default Configuration
KUSANAGI is built with security-focused defaults suitable for production workloads on AWS:
- Reduced Attack Surface: Unnecessary services and daemons are removed by default.
- *Hardened Permissions: Secure file and directory permissions are applied out of the box.
- Optimized Middleware Configuration: Nginx, Apache, PHP, and MariaDB are pre-tuned to limit information exposure and prevent common misconfigurations.
These defaults provide a secure baseline, allowing teams to deploy quickly without extensive manual hardening.
Maintenance and Lifecycle Management
Core components are delivered through KUSANAGI-managed repositories, enabling predictable and stable maintenance:
- Predictable Updates: Manage updates using standard package management (dnf).
- Verified Compatibility: Packages are tested to ensure stability across the stack.
- Simplified Security Patching: Streamlined maintenance for long-term AWS operations.
KUSANAGI provides a scalable and production-ready foundation for agencies, startups, DevOps teams, and system integrators running WordPress and CMS workloads on AWS.
