How does Acquia Cloud Site Factory differ from Drupal Multisite?
Drupal multisite allows savvy web developers to efficiently create many sites from a single code base.
Acquia’s Cloud Site Factory is built on top of Drupal multisite, so it has many of the advantages of multisite. For example, you have single sign-on, multi-site management. Instead of logging in to multiple websites, if they're on Acquia Cloud Site Factory, log in once to Acquia Cloud Site Factory to log in to all of them. This helps users reduce the number of accounts and passwords they have to keep track of, and it allows Acquia Cloud Site Factory website administrators to view and manage all of their websites from a single interface.
But there are clear advantages that Site Factory has over Drupal Multisite. Here are four.
1. Hosting and monitoring - Acquia Cloud Site Factory provides a high-availability hosting and monitoring infrastructure across multiple web servers, with Varnish caching and replicated database servers. An operations team is on call 24/7 to test your site and keep it up-to-date with all the relevant updates and security patches.
2. The Most Secure - All of this is based on the same Acquia Cloud Enterprise infrastructure that powers and protects some of the largest and most active Drupal sites in the world. With Acquia Cloud Site Factory, you can stop worrying about site speed, site traffic, disk space, up-time, and backups.
3. Acquia Support - Acquia Cloud Site Factory provides you with access to Acquia support, providing you with professional Drupal support and how-to guidance, even for custom CSS. Accounts are also entitled to support tickets, where they can have one-on-one private support conversations.
4. Open software-as-a-service (SaaS) - There's no vendor lock-in with Acquia Cloud Site Factory. If you decide that you want to move your website to another hosting service, or even host it yourself, you can export your website at any time.
