Cloud computing is one of the most popular high-end technologies that allows businesses to manage their data, business activities, and tasks more effectively and efficiently. The software keeps on introducing advanced features that helps both the large as well as small-scale businesses.
It offers a robust disaster recovery feature that empowers small businesses to implement cloud-based backup, and recovery solutions that save time, cost, and avoid large up-front investment and integrate third-party expertise as a part of the deal.
However, some of the products and services of cloud-based disaster recovery are still growing, but some of the organizations, especially Small businesses are searching and starting to utilize cloud services for Disaster Recovery. It is an incredible feature for those who want to leverage the IT services because the usage-based cost of cloud services is appropriate for DR.
The benefit of having Disaster Recovery websites in a cloud is that it can help you reduce the requirement of data center space, IT resources, and IT infrastructure, which automatically cuts down the cost and allows small businesses to deploy disaster recovery options that were only found in large scale companies.
But disaster recovery in the cloud is not always a perfect solution. You need to clearly understand its limitations, and challenges before availing its services. There are several serious concerns regarding the security:
- Is data safely transferred and stored in the cloud?
- User’s authentication process
- Is there any type of two-factor authentication services?
- Does the cloud service provider fulfill the regulatory requirements of their clients?
But cloud computing is still a great disaster recovery platform. Here we bring you the types of disaster recovery in the cloud computing software:
Disaster Recovery in the Cloud Options
We bring you the list of disaster recovery types in the cloud options that you can choose according to your wish.
- Managed applications and managed Disaster Recovery (DR).
This is an incredible option as it allows you to position both primary production and disaster recovery instances into the cloud, which is handled by a managed service provider (MSP). It helps you reap all the advantages of cloud computing – from usage-based cost to eradicating on-premises infrastructure. Rather than doing it yourself, you are deferring Disaster Recovery to the cloud or managed service provider.
By rendering the control to the service provider, you need to make sure whether they are delivering your services within the defined SLAs for both primary and DR instances or not.
A pure cloud play is gaining popularity for email and other crucial business applications like customer relationship management.
- Backup to and restore from the cloud
In this option, both the applications and data remain on-premises. When disaster arrives, data is being backed up into the cloud and restored onto on-premises hardware. In simple words, the backup in the cloud becomes temporary for tape-based off-site backups.
In fact, backup into the cloud is comparatively simple. That is the reason why backup app vendors have been expanding their backup suites with an option to directly back up into the most sought-after cloud service providers such as Rackspace, Amazon, Microsoft Corp., etc.
However, getting data restored back on-premises within limited bandwidth can be a challenging task. There are some cloud backup service providers who are offering an option to restore data to disks that are then conveyed to the customer for local on-premises recovery.
- Backup to and restore to the cloud
Instead of restoring data back to on-premises infrastructure, it is restored to virtual machines in the cloud. This approach needs both cloud storage and cloud compute resources. You can restore the data when a disaster is declared or on a pre-staged condition.
However, it becomes crucial to upgrade pres-staging DR VMs via scheduled restores where aggressive RTOs need to be met. But you don’t need to worry because there are many cloud service providers rendering cloud virtual machines as a part of their DR offering.
- Replication to virtual machines in the cloud
For applications that need aggressive recovery time and recovery point objectives, along with application awareness, then replication is the data movement option is the best choice for you.
Replication to cloud virtual machines can be utilized to secure both cloud and on-premises production instances. In simple terms, replication is great for both cloud-VM-to-cloud-VM and on-premises-to-cloud-VM data protection.
Cloud computing is an ideal technology that extends the disaster recovery options with an objective to provide cost–effective solutions to small scale businesses.
