These days, companies are seeing the cloud as a go-to location for critical infrastructure. In fact, a 2015 survey conducted by Infosys revealed that at least 81 per cent of respondents were planning to transition their mission-critical apps to the cloud within the next few years.
Given the number of cloud environments offering high-availability solutions with almost 100 per cent uptime, will this affect disaster recovery (DR) planning? In addition, do high-availability solutions permit companies to disregard internal DR tests, procedures and future plans? The answer to both is ‘no’, according to ALLTEKS Ltd — and the following explains why.
Companies Need a Plan for Handling Data Corruption
An important component to a company’s overall business continuity strategy is DR planning. While high-availability solutions are important for critical information and systems, these solutions would be useless in the event that it replicates errors.
DR plans ensure that companies can utilise a backup to recover a system. Another benefit to this is that IT employees would no longer have to spend most of their time dealing with errors and just reapply the backup to fix the issue.
Vendors and Employees Need Concrete Direction
Although companies are free to outsource the management of critical applications, employees should still know what to do in case of major data loss due to power outages and other incidents.
They need to know, for example, where they will work when IT infrastructures are not operational. In addition, they need to know how to access the company’s applications and data required to perform their job.
Cloud Providers Need to Understand the Environment
A company that uses a third party cloud provider to manage their environment must conduct a DR test to ensure that the vendor understands the IT environment of that particular company. When companies have rehearsed and documented DR plans, vendors will know how to react during a business interruption. Vendors could also use this opportunity to go the extra mile and offer custom services that can help the company’s IT department.
Given these reasons, companies should not use high-availability solutions to replace DR plans. In fact, such solutions should supplement the DR plan to make it more effective.
