The reality in today’s global businesses is that downtime cannot be tolerated for vital applications. The most critical applications include Email platforms such as Exchange, Mobile Platforms such as BlackBerry, Collaboration Platforms such as SharePoint and the myriad of applications that rely on SQL Server.
Traditional approaches to High Availability and Disaster Recovery have focused on protecting IT, not on delivering business continuity. Clustering delivers High Availability at one level, but the resources and skills required to implement a clustering solution mean the total cost of ownership is beyond the reach of many budgets. And when Disaster strikes or whole server rooms have to be taken down for planned maintenance the business is disrupted anyway.
Many firms still rely on legacy backup/recovery technologies in the belief that a Recovery Time Objective (RTO) approaching zero delivers business availability. This approach is fundamentally flawed as the RTO typically only applies to the data element, not to the application. The result is a scope of protection that fundamentally misses the point, which is keeping the business running.
Newer technologies such continuous data protection and simple data replication have a role to play in keeping data continuously available. For less critical applications these are good solutions, but consider the operational profile of your business. Will the right IT skills be available, at the right time, to recover the applications, reconnect them with the data and keep users running?
No business downtime means being proactive, not reactive. This means understanding the deployment requirements, validating the hardware and software environment, monitoring to identify where failures may occur, and taking action to prevent avoidable outages. This is where the ability to predict the success of the operation is a precursor to protecting the business application in such a way that users continue to perform, because they remain connected throughout the outage.
Assess your risk and make sure you understand what continuous availability means for your business. Then, take a look at Neverfail, the only high availability solution that;
