WooCommerce is more dynamic than a simple brochure site because cart, checkout, customer sessions, inventory and order data depend heavily on PHP and the database. Full-page caching helps product and content pages but cannot cache every personalized interaction.
What to consider
Prioritize strong CPU and memory resources, fast storage, database performance, backups, SSL and reliable email delivery. Monitoring becomes important during campaigns and seasonal traffic peaks because resource pressure can directly affect checkout experience.
As the store grows, consider moving from standard managed hosting to higher-resource cloud hosting or a VPS when measured usage shows sustained pressure.
