NETWORK FUNCTION VIRTUALIZATION OVER CLOUD - DISASTER RECOVERY SOLUTION OVER HYBRID CLOUD

摘要

In recent years mobile operators have been facing many challenges to achieve the continuity of running services to the users when enterprise datacenter fails. The solution of this project achieves automatically the recovery of datacenter virtual machines by Disaster recovery solution. Disaster recovery (DR) strategy is widely considered as a base-line requirement for many organizations. Historically, DR solutions have been expensive and complex to deploy. This meant that only the largest organizations could afford DR and only then if they had a technically sophisticated IT team. The expense and complexity problems of deploying DR have persisted into recent DR solutions, and this leaves many workloads vulnerable. This then exposes businesses to a range of issues like compliance and audit violations that lead to loss of valuable data. To create a disaster recovery solution, an alternative location must be prepared to be able to recover a datacenter at the occurrence of failure so the business can continue to run. Microsoft Azure is the public cloud to offer Disaster Recovery solutions for applications running on Infrastructure as a Service (IaaS) by replicating VMs into another region even when failure occurs on a region level.
