The Challenge

Our company website was running on a WordPress multisite installation hosted on Amazon Lightsail, costing $12/month for a single site that rarely changed. The setup was overkill for our needs and came with several pain points that needed addressing.

💰
Unnecessary Costs
Paying $12/month for WordPress hosting plus $20/month for orphaned WAF instances that were no longer needed.
🐌
Performance Issues
WordPress overhead resulted in slow page loads, especially for first-time visitors, impacting user experience and SEO.
🔧
Maintenance Burden
Regular WordPress updates, plugin maintenance, and security patches required ongoing attention and created vulnerability windows.
