Shared hosting
A good fit for small sites using common CMS platforms. The provider maintains the server, with limits on resources and configuration. Check supported PHP versions, limits and restore options.
VPS and dedicated servers
A VPS provides more control and isolated resources but needs configuration and updates. Dedicated hardware suits high loads or specific requirements. Assign responsibility for administration and monitoring upfront.
What to check with the provider
Check server location, backups, recovery conditions, access, support and renewal pricing. Assess personal data hosting requirements against your actual data and processing arrangements.
A planned migration
Test a copy on the new server before switching DNS. For stores, plan how to carry over new orders and schedule the change window. Keep the previous hosting until the site and mail are verified.
