DRaaS offerings are mature and constant. Now IT just must think differently about continuity.
It’s 3:30 a.m. in a raging supercell thunderstorm. Did you know where your disaster recovery plan is? How about your backup data, redundant servers, and rancid-site facility? Are you able to spin up mission-critical business applications?
And no, two out of 3 isn’t ok.
Everyone pays lip service to the significance of resiliency, but CIOs have plenty of priorities, with more added on daily basis: work out whether software-defined networking is a fit, how much of the IT budget the CMO now controls, and the way the heck DevOps would ever work here. Spending hundreds of staff hours and 7 figures to mitigate a 1%, or perhaps 10%, risk scenario — after which keeping that plan current in today’s level of technology churn — doesn’t look like an awesome return on investment if you are struggling to fulfill new service requests. Consequently, just 41% of respondents to our InformationWeek 2014 State of Enterprise Storage Survey say they’ve got a disaster recovery and business continuity plan and test it regularly.
But what once you could shift the price equation of disaster recovery one decimal point to the left by being open to a brand new way of doing business?
Cloud-based disaster recovery services combine public cloud infrastructure and SaaS automation software to make implementing world-class continuity easier than it’s ever been. Today’s disaster-recovery-as-a-service market includes big IaaS shops along with Amazon Web Services and IBM in addition to specialists including PHD Virtual and Zerto. For data transport between on-premises and cloud-hosted systems, it’ll benefit from enterprise-class cloud backup and replication software from firms like Asigra, CommVault, and TwinStrata. Cloud providers maintain geographically distributed datacenter facilities with state-of-the-art uptime and security.
If you tier your data and prioritize services and applications, that you may exploit granular subscription models that reflect a variety of cost, performance, availability, recovery time and recovery point objectives, and redundancy options.
When does a DRaaS offering reach the extent of enterprise class? It must transcend the fundamental cloud-based backup services we profile in our InformationWeek Cloud Storage, Backup and Synchronization Buyer’s Guide to incorporate an entire panoply of application encapsulation, data replication, failover/failback automation, and testing services that deliver familiar IT runbook processes in a service model.
Backup is solely about data protection, while disaster recovery is restoration of the whole application infrastructure at another facility, explains Network Computing contributor David Hill. Business continuity is ready both operational recovery and disaster recovery. “Operational recovery relates to recovery from a particular problem at a first site, comparable to a server, application, or disk failure,” writes Hill. Cloud DR and BC services bundle three elements: off-site data protection, automated infrastructure and alertness recovery, and, when it comes to DR, cloud-hosted virtual infrastructure.
From IT’s perspective, automating the disaster recovery process and turning it right into a service simplifies testing and validation and makes it possible for easier setup of multiple failover snapshots for various system and alertness configurations. Furthermore, moving DR to the cloud means there is no redundant infrastructure that you simply build and maintain but that sits idle in general, and few software images to maintain patched and updated.
The existing approach doesn’t inspire great confidence. Our 2013 Backup Technologies Survey shows 66% still backing up on to tape and just 27% extremely confident of their ability to get the business up and running again in an inexpensive time-frame after a big disaster takes out the foremost datacenter. Scary, but likely accurate given the pace of recent applications coming online.
Cloud makes the DR scenario simpler and highly reproducible. So why isn’t everyone buying in? One reason is that the full cost of cloud DR isn’t clear cut, and another is that familiar cloud concerns around performance and security hold some back.
Moreover, the stumbling block to quick business recovery is sometimes not data, it’s applications. Definitely, one bright spot is that the majority enterprises are quite rigorous about retaining data. Our backup technologies survey found 71% of respondents clone 90% or more in their physical systems weekly.
Recovering applications is where the breakdown occurs. Eleven percent of backup respondents haven’t tested the restore process for some or all in their applications, while 45% achieve this haphazardly.
Our advice for the cloud-wary is to have a look at adopting DRaaS as a 3-step process: Get some cloud storage, then backup, then go all in on disaster recovery.
