Businesses and organizations of all sizes have adopted virtualization as a core technology within their data centers. Both new and legacy applications are moving to virtualization because it reduces cost, improves hardware utilization and simplifies management. Originally, proprietary virtualization platforms were the dominant forces in the industry. Lately, customers have realized that open virtualization platforms provide higher performance, better functionality and are more cost effective.
The rapid adoption of virtualization has driven demand for support of High Availability (HA) and Disaster Recovery (DR) functionality. Businesses rely on an "always on" IT infrastructure in order to provide competitive advantage and create unique customer values. Applications built on virtualized environments must deliver appropriate levels of availability with minimal or no downtime.
Red Hat and Symantec enable IT organizations to offer a highly scalable virtualization infrastructure for traditional and cloud-enabled applications while maintaining high levels of business continuity. Red Hat Enterprise Virtualization provides an enterprise-quality virtualization platform built on the open-community development model. Red Hat Enterprise Virtualization is based on two major open source projects: Kernel-based Virtual Machine (KVM) and oVirt. It is a small form-factor, scalable, high performance hypervisor based on Red Hat Enterprise Linux and provides the same security, performance and scalability that are built into Red Hat Enterprise Linux. SymantecTM Cluster Server, powered by Veritas, increases the business resiliency of Red Hat Enterprise Virtualization by providing automated wide-area application failover that spans virtual, physical and multi-tier environments.
Symantec and Red Hat collaborate to deliver an optimized failover solution. This paper examines the advantages that the integration of Red Hat Enterprise Virtualization and Symantec Cluster Server provides to address application high availability and disaster recovery for virtualized environments.
