Virtualization

VMware vSphere is VMware's virtualization platform, and vCenter and ESXi are both important components of vSphere. VMware vSphere, vCenter, and ESXi were initialized as different technologies for different purposes, but now they're combined into the vSphere platform. In this article, we discuss vSphere, vCenter Server, ESXi, and the differences between them. Read more: VirtualBox vs VMware: Choosing the Best Virtualization Tool What Is vSphere? vSphere is a...

In the world of server virtualization, Proxmox and ESXi are two frequently mentioned examples of viable hypervisors. But how does Proxmox, an open-source solution, fare against longtime virtualization giant VMware and its hypervisor ESXi? This article looks at what to consider when choosing a hypervisor, explains the Proxmox Virtual Environment and vSphere ESXi, and discusses how the two compare to meet server management objectives. How to...

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...

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...

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...
