Technical point of view: A methodology for cloud computing disaster recovery

You are not the only one who considers cloud services. In fact, every IT organization is talking about the cloud as a way to improve service quality, save money, change the way it works, or gain other benefits. While cloud computing is not designed for everyone, it offers a huge advantage for understaffed it stores, from wholly-owned enterprises to multinational companies with millions of of staff services and any service that can be deployed internally, cloud computing can provide services, and can save a lot of budget.

However, when a company moves services to an external supplier, they are responsible for transferring all the services, regardless of whether they are functioning properly. For any user, the most important issue to consider when investigating a service provider is the disaster recovery of cloud computing. There are a number of key areas that you want to identify and fully understand to ensure that they meet business needs without disaster.

A disaster is a warning to another disaster

I'm sure every good cloud service provider has its own disaster-recovery plan; they do the testing and authentication, and there are effective multiple area resources to support the operation when the site is lost, but if I want to consider a vendor, I want to know what disaster fixes are, how they are implemented, and what it means to me and my users. If there is a disaster in my company, I am interested in how the cloud service provider can give me help.

Read SLA

In fact, you need to spend time reading and understanding the SLA provided by your cloud service provider. Ask and simulate scenarios to confirm that you fully understand what triggers the disaster, the impact on your SLA, and the details of the disaster fixes. Who announces disaster, what procedures and techniques can minimize the impact on customers and the time to repair the service. A few hours of downtime may seem like a long time, but your business should be able to survive, and if not, this cloud service may not be right for you, but no business has to deal with a long interruption of supply for a few days a day. You have the right to loan on your own account, but the repair service is more important.

RPO Recovery Point Objective

The term disaster implies that something bad happens when it is in IT services and usually implies data loss. Make sure you understand the recovery-point objective of the service to see how much data will be lost in the event of a disaster.

RTO Recovery Time Objective

Publish recovery time objectives in front of each stakeholder and confirm that they understand and agree to this recovery time goal. If your cloud service provider experiences disaster, they should be able to repair the service within the recovery time target. The boss yells at you, lets you order them to hurry, it doesn't help, so you have to make sure everyone knows the time of recovery.

Disaster-recovery Testing

An increasing number of cloud service providers provide multi-tenant services, meaning that they follow your schedule or program for disaster-repair testing. Review their disaster-recovery test plans and results and confirm that they can complete all internal and external tasks. You may have to adapt your disaster-recovery plans and procedures to your work under the supplier's limitations, so you need to be aware of its impact on audit, certification, or user contract obligations before you commit to the service provider.

Cloud computing has the potential to save a lot of it budgets for companies and to provide services that they cannot do themselves. A comprehensive understanding of how cloud computing provider disaster-repair operations can ensure a smooth application and ensure that the disaster returns to its normal state at the least level of damage.
