Rackspace has two primary lines of business; Cloud Servers and Dedicated Servers. Rackspace helps design, build, and operate workloads across both environments depending on the individual needs of the customer. Cloud Servers The Managed Infrastructure service level provides a core set of services necessary to set customers up in the cloud, including architecture advice, security assistance, and code development assistance (through APIs and SDKs). The Managed Operations support level provides all Managed Infrastructure services plus additional proactive support. Dedicated Servers The Managed service level consists of on-demand support where proactive services are provided, but the customer can contact Rackspace when they need additional assistance. The Intensive service level consists of proactive support where many proactive services are provided, and customers receive additional consultations about their server configuration. Highly customized implementations generally fall under this level of support.
