IT disaster recovery, cloud computing and information security news

Continuity Software has announced the release of its 2016 Private Cloud Resiliency Benchmarks. Based on data gathered from over 100 enterprise environments over the past year, the study found that downtime and security risks were present in each cloud environment tested. The study also found that security and performance risks were found in 99 percent and 97 percent of the environments respectively, with 82 percent of the companies facing data loss risks.

Some of the top risks identified across the private cloud environments included in the study consist of the following:

  • Configuration drifts between cluster nodes that prevent failover. Examples for such discrepancies range from the most trivial - e.g., a file that is not accessible by all hosts in the cluster - to more complex ones - such as incorrect settings of affinity rules.
  • Virtual networking configuration errors leading to virtual machine isolation and downtime. Examples include incorrect Virtual Machine Port Group configurations and resources misalignment between ESXi cluster hosts leading to a single point of failure.
  • Incorrect storage settings leading to corrupt backups and data store loss. Such risks range from invalid CBT configuration to inconsistent LUN numbering and incorrect UUID settings. 

What do these private cloud environments look like?

  • 48 percent of the organizations included in the study run their virtual machines on Windows compared to 7 percent of the organizations that run on Linux. 46 percent of the organizations use a mix of operating systems.
  • Close to three quarters (73 percent) of the organizations use EMC data storage systems. Other storage systems used include NetApp (38 percent), IBM (26 percent), HP (24 percent) and Hitachi (18 percent).
  • 27 percent of the organizations use replication for automated offsite data protection.
  • 12 percent of the organizations utilize active-active failover for continuous availability.
  • Almost all of the organizations (96 percent) use more than one physical path to transfer data between the host and the external storage device.
