Abstract
A datacenter infrastructure comprising a plurality of datacenters is configured to provide services to users. Data (e.g., application data) provided to respective datacenters from a user is synchronized between different datacenters comprised within 'a cloud' according to a multilevel synchronization scheme. Respective levels of the multilevel synchronization operate to transfer different priority (user) data between the plurality of datacenters, wherein respective priorities are determined based upon the importance of the data in providing a service. For example, data used to perform a service is synchronized by a synchronization component facilitating a higher level of synchronization between datacenters, while data not routinely used to perform a service is synchronized by a lower priority synchronization component. Synchronization between datacenters allows a network address routing system to provide substantially uninterrupted routing of a user to an available or otherwise appropriate datacenter within the datacenter infrastructure, thereby providing increased service reliability and performance.
