The rapid adoption of server virtualization has enabled many organizations to significantly reduce their IT capital expense, operating costs, as well as adapt to changing business requirements more easily and improve overall server availability.

However, when it comes to extending the benefits of server virtualization to their mission-critical business applications, many organizations often struggle. Understanding how to re-architect their environment and strike the right balance between performance, scalability, manageability and most importantly, high availability and disaster recovery is a constant challenge.

Protection in a Virtual World

When organizations look to virtualize their mission-critical business applications, careful consideration must be given to ensure that nothing impacts performance, scalability and manageability. Nothing can compromise the continuous availability of the entire business application. Such concerns have led many organizations to part-virtualize their server farms, often leaving the Database tier completely untouched as well as many other high performance application servers.

However, while part-virtualizing the server farm ensures performance and scalability, it does require that the availability of virtualized and non-virtualized servers be handled in different ways. Various server virtualization platform availability features, such as VMotion, HA/FT, CSV, and Live Migration cannot protect both virtual and physical servers. This situation is compounded when looking to design for remote site availability or disaster recovery, as neither VMware SRM nor Microsoft DPM support mixed physical, virtual, local and remote site availability configurations.

Continuous Availability using
Neverfail Continuity Engine

The VMware® vSphere and Microsoft® Hyper-V platforms incorporate many platform-level technologies (VMware HA, FT, VMotion, Storage vMotion, SRM, Live/Quick Migration etc.) that can significantly improve overall system resilience and server availability.

However, when it comes to protecting your mission-critical business applications across mixed environments with local and remote sites (for disaster recovery), these technologies do not provide complete protection for your applications. Absent from these platforms is protection from the most common causes of downtime, such as application failure, service failure, performance degradation, configuration drift, user error, etc.

Neverfail Continuity Engine is the only solution that covers all of the common high availability and disaster recover deployment scenarios. Continuity Engine provides complete protection against downtime for mission-critical business applications in physical, virtual and mixed environments.
