Virtualization

Virtual servers have the same capabilities as a physical server, but not the underlying physical machinery. A physical server can create multiple, separate virtual servers with a hypervisor or container engine using virtualization technology, and the instances share physical server resources like CPU and memory. Not long ago, some feared a future of bustling data centers covering the globe. While that sounds hyperbolic, spatial considerations...

Containerization is the solution to the roadblocks posed by traditional virtualization. Since their inception, virtual machines (VMs) have enabled organizations to do more with less. A single physical device can contain several isolated, virtual environments through a hypervisor, and the benefits include reduced overhead, convenient mobility, and scalability. Sounds great – but there’s one problem. Virtual machines are heavy units. Because a significant appeal of virtualization...

Yes, data centers and server rooms are changing. The explosion of cloud infrastructure solutions enabled organizations to adopt large virtual workloads while innovative server technology offers more in less space. Though effective in causing the downward trend we've seen in recent years, these trends hardly mean the end of on-premises infrastructures. Through several years of trial-and-error, industry thought leaders are clear: the future of enterprise...

The power of computers transformed the world in the last century. Today, they serve our critical infrastructure, business operations, and more. Though tempting to think of a universe of physical machines in office buildings and server farms, virtual machines (VMs) have actually been the cornerstone of enterprise computing in the new millennium. A VM gives administrators the power to manage hundreds of virtual computers from...

Understanding the differences between virtualization vs. containerization can lead to improved scalability and reduced operational costs for organizations. In this article, we'll discuss the specific differences between both methods of creating virtual packages as well as the general differences between these two valuable solutions. Discussions about server virtualization inevitably revolve around VMware, Hyper-V and, to a lesser extent, Xen and KVM as well. But another...
