Virtualization

Cloud computing security, or cloud security, is a set of policies and technologies to protect the services and resources of the cloud computing system. Cloud security is a subdomain of cybersecurity, and includes processes to protect services, applications, data, virtualized IP, and the related infrastructure of cloud computing systems. Virtualized environments, including virtual machines (VMs) and containers, present unique risks to cloud security. Here, we...

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...

In this product review, we'll be covering IBM PowerVM server virtualization. We'll discuss the virtualization tool's features as well as its pros and cons. What is PowerVM? IBM PowerVM can virtualize AIX, IBM Linux and IBM i clients running on its Power server platform. It is one of the most full-featured virtualization programs on the market – no surprise, given IBM’s deep legacy in the data...

Server virtualization software burst onto the scene in the early 2000s. The meteoric rise of VMware came as organizations were at the outset of deploying multiple virtual machines (VMs) on one physical server. Gone are the days of low rates of server utilization and one physical server hosting one application. Here are the top server virtualization software vendors that you should consider for your business....

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...

vSphere 7, the latest version of VMware’s server virtualization product, was made generally available April 2, 2020, with an expanded feature set and updated security tools. From Monster VMs that double the number of hosts per cluster to drop-in Kubernetes capabilities, vSphere 7 makes life easier for enterprise IT Admins and developers looking to streamline their infrastructure. These are the new and updated vSphere...
