Survey Reveals Widespread Inadequacies in Email Outage Prevention

King Research A new study conducted by King Research, and sponsored by Teneros, surveyed 220 IT professionals responsible for messaging systems in mid-market companies. The goal was to gather data on the activities and products that IT teams are using to ensure messaging continuity, as well as to investigate key challenges faced by the individuals responsible for keeping their corporate email up and running. The research suggests that while most companies are clearly aware of the damage email downtime can do, that knowledge has not yet translated into increased spending on technology and human resources to prevent downtime, hence, outages are still a reality.

Messaging Application Continuity

There are various higher-level messaging continuity strategies that either replicate messaging data to backup storage environments or seek to add redundancy to critical parts of the messaging architecture. These approachs mirror the complete messaging infrastructure, or provide some type of standby or hot/standby duplicate system. All have their place as well, but may not provide a complete solution and usually require a very complex infrastructure, heavy IT involvement and very heavy cost.

Organizations that require a better assurance of messaging continuity can look to turn-key solutions that provide full messaging continuity and backup. These purpose built devices are supplied at a much lower cost than the cost of building a replicated infrastructure.

A final approach is to subscribe to an off-site “backup” service that attempts to capture messaging traffic when notified of a failure in the messaging system and provide an alternate means of delivery, typically through web-based messaging. Users are notified via wireless, through non-company email addresses or other means of delivery. For this an ongoing subscription is usually the norm. This approach offers fast setup and little IT involvement. Disadvantages of these continuity services include high recurring subscriptions costs, gaps in continuity coverage, complexity for the end-user, slow performance, and company assets that are no longer under tight security.
