Virtuozzo OS Server Virtualization: Business Continuity (HA/DR)
Ensuring that an application and data are safe and available is a requirement in every IT organization. Balancing the cost and resources required with the desired level of high availability or disaster recovery time produces a range of solutions and requirements. Parallels Virtuozzo Containers provides IT organizations with cost effective options for making data highly available and recoverable.
Actual Disasters
When a server resource becomes completely unavailable, there are many approaches to recovering data and making or keeping the application available. Each approach is dependent on the application and organization’s requirements for recovery time.
Virtuozzo Containers Advantage: Enabling Cost-effective DR Solutions
Virtuozzo Containers can be a cost-effective component of any disaster recovery/ high availability solution, from an always available solution, to a fast recovery or backup recovery solution. Virtuozzo is the perfect solution for housing redundant servers that can be activated as necessary. Virtuozzo’s mean time to repair (MTTR) is much shorter than many other options because of the smaller server virtualization footprint. It also has a much faster boot time because only the processes and data are booting, the operating system is already available.
Impending Disasters
Some natural disasters and hardware failures come with warning systems. Most hardware manufactures now have drivers that detect problems with hardware components such as motherboards.
Virtuozzo Containers Advantage: Proactive Disaster Mitigation
Virtuozzo Containers migration capabilities allow VEs to be moved in real-time with near-0 downtime (keeping the application available through the migration until the last few seconds), and no SAN is required. Any threat of system failure or impending catastrophic event can be minimized by moving VEs to any Virtuozzo Containers server with any hardware configuration in the time of data transfer.
Availability "Disasters"
Critical applications must be available 24x7 without hesitation and an overloaded application can appear to be unavailable.
Virtuozzo Containers Advantage: Flexible Resource Management
Applications virtualized on Virtuozzo enjoy complete flexibility of resource management, resources maybe added or reduced in real-time without service interruption. Overloaded applications can quickly and easily be provided with more resources.
