Introduction It is not hard to see the rapid growth of computer technology and the common usage on internet services across different industries. Many companies rely on Disaster Recovery (DR) services to minimise data loss and shorten the recovery time. However, the current DR services may be costly, or low efficiency about the amount of data loss and the time required restoring. In this essay, we intro the cloud services as the most suitable tool for DR due to the ‘pay-as-you-go’ model, which lower the costs and the automated function reduced the recovery time after any disaster occurred. Although Cloud Computing may not suit all enterprise, it did have huge advantages for organizations which were understaffed. It is not only able to…show more content…
The system is usually in a Replication mode for normal operation, so it only requires a low cost Virtual Machine (VM) to act as a DR server to handle the synchronisation. While there is disaster detects, the system enters into a Failover mode and uses resources to support all applications. Different types of cloud models available for different types of business needs and helps to manage the DR server to reduce the impact on disaster. The automated virtualised cloud platforms may not specific to cloud services but it did provide significant feature for DR. It starts automatically, which obviously shorten the recovery time; the resources were also, synchronised from primary site to the cloud rapidly when the disaster is detected. DR requires a Recovery Point Objective (RPO) and Recovery Time Objective (RTO). RPO means the point of the most recent backup prior to any disaster. Understand the RPO service helps to know how much data can be lost in the event of a disaster. RPO is related to the recovery objectives defined in the DR plan, especially for critical business applications and data stores. The situation of Zero-data-loss is established on the basis of the above data protection policy. RTO is a business decision that specifics on how long does the service takes to return to normal. In a DR solution, RPO and RTO (recovery time objective) needs to
