Backup and Disaster Recovery (BDR)—a combination of data backup and disaster-recovery solutions that works cohesively to ensure an organization's critical business functions will continue to operate despite serious incidents or disasters that might otherwise have interrupted them, or will be recovered to an operational state within a reasonably short period.
Managed services and outsourcing works exactly the same. However managed IT services and traditional IT services are different. Pay attention to the words managed and tradition outsourcing given. It is basically obtaining services from a third party. There are different ways of observing one is traditional IT services the other one has managed IT services. So basically these two are different models through which IT services are outsourced.
Cloud computing has allowed managed IT services to expand beyond the regions and borders that would constrain the average break/fix IT through the adoption of Software as a Service (SaaS) technologies, as well as Infrastructure as a Service (IaaS) and Platform as a Service(PaaS) also. These capabilities allow managed IT services to scale at a rate dramatically larger and faster than in-house IT operation or break/fix providers.
