Cloud-based disaster recovery becoming more popular

Nearly half of US companies use the cloud to help with disaster recovery (DR) and business continuity, a new report has revealed.

The CompTIA Fifth Annual Trends in Cloud Computing study found 48 per cent of organizations in the country now rely on the technology to quickly recover from catastrophic events.

According to the research, an increasing number of everyday business processes are being shifted to cloud, with nine out of 10 enterprises using the this form of modern IT to improve operational capacity.

DR in the cloud has significant benefits, allowing companies to continue running mission-critical functions when unforeseen problems arise. Potential issues include natural disasters, power outages and hardware or software failings.

For example, creating and maintaining multiple standby databases in the cloud means that in the event a primary database becomes unavailable, IT departments can switch to a binary copy to reduce downtime. Because these replicate databases are cloud based, they are protected from disasters that could destroy other backup measures kept in physical locations.

Furthermore, the latest real-time replication techniques ensure the data in the standby databases is synchronized to updates in the source system. In the event of a disaster, this minimizes data loss.

Aside from business continuity, the CompTIA study showed cloud computing is also used for storage and security purposes. Fifty-nine and 44 per cent of firms have shifted these functions to the cloud respectively.

Respondents cited reduced costs as the primary benefit of cloud computing, as there is limited upfront capital expenditure when compared with on-premise solutions.

The statistics also showed businesses aren't afraid to change services to select the best setup for their particular circumstances. One-quarter of firms had moved from a public to a private cloud in the past, while 44 per cent had shifted infrastructure and apps from one public cloud platform to another.
