Domino’s Pizza finishes last piece of cloud computing move
Domino’s Pizza has completed a major move to cloud computing, aimed at freeing up internal resources. The company is using the hosted RackConnect service from supplier Rackspace for its applications and platforms.
Domino’s Pizza UK is moving its e-commerce site, online payment gateway, corporate e-mail and back-office systems into the cloud, with the aim of increasing scalability and saving money.
RackConnect will enable Domino’s to select which applications are placed where in the managed hosting infrastructure. For example, applications that require a high level of security, such as an internal e-mail system, can be hosted on dedicated physical hardware.
Domino’s will also be able to take advantage of the on-demand scalability the Rackspace cloud offers, for instance, developing new smartphone or tablet applications, or handling the demands of a digital marketing campaign.
Domino’s new hosted architecture is expected to go live this September.
