Research The impact of cloud-native disaster recovery
Enterprises continue to turn to the cloud for backing up data and hosting virtual machines. Once in the cloud, however, virtual machines still need to be protected. After all, accidents can happen in the cloud, too, and anything from an accidental deletion to ransomware can compromise your cloud-based VMs.
This is why it’s necessary to have a strong disaster recovery plan that covers not only your mission-critical on-premises VMs, but also VMs running in the cloud, such as with VMware Cloud on AWS. One that is integrated into your overall data protection plan that leverages the cost and computing advantages of the cloud.
Making the business case for cloud-native disaster recovery
Historically, disaster recovery included dedicated data centres standing at the ready for failover in the event of disasters. It was the most expensive and complex option for DR, which only the biggest companies could afford, and only for the most mission critical applications. This left most business and applications vulnerable, hoping that disaster didn’t strike.
The emergence of SaaS data protection has enabled cloud-native disaster recovery at a fraction of the cost of legacy DR solutions. Cloud-native disaster recovery offers clear advantages to customers using cloud-based data protection solutions such as:
- Lower cost as SaaS subscription models replace dedicated hardware
- Expanded DR coverage for applications / workloads
- Ability to recover VMs in the cloud within minutes
- Workload mobility across cloud regions
It’s clear that reducing the cost of disaster recovery, making it simpler and more scalable, and guaranteeing RTO / RPO objectives has clear advantages over legacy solutions. However, it’s also important to consider the implications of NOT planning for disaster. In the US alone, the cost of downtime from disasters can be as high as $4M, and in many cases, small to medium size businesses will never recover from a major disaster. The impact of downtime to your business needs to be factored into your DR planning.
Given the availability of low-cost, on-demand disaster-recovery solutions, it’s surprising that DR is still often an afterthought. The need to act is clear. At a minimum, basic DR planning needs to happen immediately, and choosing the right technology is key. Given the advantages, including low cost, using emerging best practices and technology is a no-brainer.
