For companies looking to develop and then test, stage and run a Drupal site, Acquia’s hosted Dev Cloud service provides an affordable solution to either on-premises hosting of your own Drupal server or going with a general hosting service who may not be as familiar with the oddities of setting up your Drupal server and various add-ons.
You can launch a variety of pre-configured servers and Acquia will manage and maintain them as any other MSP. One big benefit is that you can quickly set up multiple servers with their self-service provisioning tools, making it easy to start with a dev/test environment or the ability to increase your server instances as your computing needs increase.
Pricing starts at $150 per month and there is a very clever page that is used to calculate your monthly price with a great graphical look and feel that other cloud providers could do well to emulate.
