Why Cloud Disaster Recovery?
Virtualization-based cloud computing has an alternative approach to that of disaster recovery. The whole server, as part of a virtualization, is entailed and embodied in a solitary virtual server or software bundle, including all the operating system, patches, applications, and data. As a result of this, the totality of the virtual server can be copied and backed up in a Datacenter off-site so that a virtual hosting service can be launched in a matter of minutes.
The operating system, the applications, the data, and the patches can all be transferred safely and securely from one data center to another data center because they are an independent of hardware and so they can be moved to a second data center without the need to reload every server component. Compared to non-virtual disaster recovery systems, this process is both faster and more secure, as traditional means demand that the most recent configuration utilized in production needs to be loaded, onto a new server along with the software applications and operating system prior to any data being restored and recovered. Hence, disaster recovery is both faster and more secure through virtual data recovery, facilitating more expedient recovery times.
Cloud Computing delivers faster recovery times and multi-site availability at a fraction of the cost of conventional disaster recovery.
Our cloud clients and customers are in control thanks to TELEHOUSE’s 48 tier III+ data centers located in different countries and cities worldwide. You are able to determine the means by which the data recovery travels, where the data recovery services are located, and how you gain access to them as a TELEHOUSE customer. Choosing among one of 28 different global cities, you are able to select where your Virtual Disaster Recovery infrastructure is stored, just like physical Data Center Infrastructure.
How does Cloud Disaster Recovery work?
Traditional disaster recovery is outdated, and cold site recovery has been superseded the cloud. Indeed, with warm site recovery options, in the event of a disaster you are able to recover all your data assets with inexpensive ease, indeed, in a matter of minutes you can spin up critical server backups on a private or a shared cloud platform.
A more cost-effective and attractive option is facilitated though SAN-to-SAN replication sites, ensuring that data recovery following a disaster is fast and more appealing. In the past, this was not the case as there were several arduous and expensive challenges resulting from disaster data loss. Multi-site availability is one of the most promising and enticing aspects of cloud-based disaster recovery. Furthermore, through using SAN relocation, not only is the disaster site provided with rapid failover but furthermore, return to the production site (once the event or the recovery has finished) is also possible.
The ability to tailor and fine-tune the particular elements, performances, and costs of the disaster recovery platform is among the main advantages of cloud-based disaster recovery. Indeed, if you have fewer resources then you can tone down the less significant or important servers and applications but still guarantee that the most important applications are provided with the mans and resources required to ensure your firm keeps up and running throughout and despite the disaster event.
Critical Path in Disaster Recovery – Networking
As a result of the significant changes resulting from cloud-based IT disaster recovery, network replication is now a critical pathway. Production network replication at the data recovery site is the critical path for disaster recovery option as part of fast server recovery at a data center located offsite. This incorporates firewall rules, IP-address mapping, and VLAN configuration.
Full data recovery services are provided by Smart Data Centre Operators. These do not merely replicate servers among different data centers but they are also able to copy the whole of the configuration of the network so that it may be quickly backed-up on cloud servers.
Benefits of Disaster Recovery in Cloud Computing
The big difference between cloud-based disaster recovery and traditional recovery practices is the difference in RPO and RTO. With cloud-based DR, your site has the capability to recover from a warm site right away, drastically reducing your RPO and RTO times from days, or even weeks, to hours. Whereas traditional disaster recovery involved booting up from a cold site, cloud recovery is different. Thanks to virtualization, the entire server, including the operating system, applications, patches and data are encapsulated into a single software bundle or virtual server. This virtual server can be copied or backed up to an offsite data center and spun up on a virtual host in a matter of minutes in the event of a disaster. For organizations that can’t afford to wait after a disaster, a cloud-based solution could mean the difference between staying in business or closing its doors.
Cloud storage is very cost effective, as you can pay for storing only what you need. Without capital expenses to worry about, you can use “pay-as-you-go” model systems that help keep your TCO low. You also don’t have to store a ton of backup tapes that could take days or to access in an emergency. When it’s already expensive to implement a DR plan, having your recovery site in the cloud can help make it more affordable.
Putting your disaster recovery site in the cloud allows for a lot of flexibility, so increasing or decreasing your storage capacity as your business demands it is easier than with traditional backup. Rather than having to commit to a specific amount of storage for a certain time and worry whether you’re meeting or exceeding those requirements, you can scale your storage as needed..

Despite any myths to the contrary, having a cloud-based disaster recovery plan is quite secure with the right provider. Cloud service providers can argue they offer just as much, if not more, security features than traditional infrastructure. But when it comes to disaster recovery for your business, you can’t afford to take chances. Make sure you shop around and ask the tough questions when it comes to backing up your production site.
It should be noted that if you already have your production site hosted with one cloud service provider, it would be smart to host your recovery site with the same provider. That way, you can cut down on confusion and have a smoother failover process (should you need it) because you’ll have use of the same technology and staff that you already use for your production site. This is where you should look to a full IT service provider who can offer you what you need to keep both your production and recovery sites running smoothly.
If you’re thinking of moving to a cloud-based disaster recovery plan, there are some big benefits to be found. In a future post, we’ll talk about what kind of cloud is best for your business, whether it’s your production site, recovery site or both.
