Scaling Up On Demand with Red Hat Enterprise Virtualization

Among many other compelling features of Red Hat Enterprise Virtualization, the ability to hot plug memory is the best. Red Hat Enterprise Virtualization 3.6 provides the extended capability to hot plug vCPU’s to running virtual machines. Red Hat team has been working hard to accomplish this vision of hot plugging resources on demand.Scaling Up On Demand with Red Hat Enterprise Virtualization

Has anyone really wondered that why do resource hot plugging capabilities matter to an IT organization? The two mentioned features when paired together, solve real problems which is the ability to truly scale your virtual machines on demand. Traditional applications are still rooted in stateful monolithic architectures. These applications typically scale “vertically”, by adding CPU and/or RAM to the virtual machine that hosts the application. This process typically requires a reboot, a manual configuration change, and of course a service disruption. The ability to hot plug virtual CPU’s and virtual memory allows IT organizations to scale up on demand without service interruption. The ability to hot plug these virtual components is intuitive in the Red Hat Enterprise Virtualization administration portal, but it’s infinitely repeatable with the REST API. This means that if you’re building an Infrastructure-as-a-Service around Red Hat Enterprise Virtualization with something like ServiceNow and/or Red Hat CloudForms, this type of activity can be tracked, automated, and orchestrated – much like a lightweight private cloud.

Red Hat has been constantly focusing on automating manual tasks to simplify enterprise IT operations. The ability to hot plug resources enables organizations to meet service level agreements, streamline management, and easily integrate into the existing infrastructure.
