What WooCommerce hosting needs
Short answer: WooCommerce hosting needs more memory and CPU than a basic site, because cart, checkout and account pages cannot be fully cached. Look for at least 2 GB of memory, a current PHP version, SSL, daily backups, a firewall and staging for testing updates.
1. Uncached pages
Cart, checkout and My Account bypass page cache, so every visit uses server time.
2. Memory
Plan for 2 GB or more for a store; busy stores need more.
3. Backups and staging
Test plugin updates on staging and keep nightly backups.
4. Security
A firewall and malware monitoring protect payments and customer data.
