virtualization vs containerization

First, KVM IntroductionKVM (kernel-basedvirtual machine), a kernel-based VM, is a virtualized infrastructure used in the Linux kernel to transform the Linux kernel into a hypervisor. KVM was introduced into the Linux 2.6.20 core in February 2007 and ported to FreeBSD and Illumos in a way that can load core modules.KVM runs on an x86 platform with Intel VT or AMD-V capabilities. It is also ported to the S/390,POWERPC and IA-64 platforms. In Linux kernel version 3.9, support for the ARM architectu

Higher server utilization, faster delivery capability, more energy-saving and environmental protection, virtualization brings a lot of benefits to enterprise it. However, as the scale of virtualization expands, new problems arise: ·Virtual Machine flooding.As the business grows, there are more and more virtual machines. Because the virtual machines and services cannot be effectively linked, it is back to th

Almost all of the virtualization vendors are shouting "Full virtualization!" "Slogan, many users are starting to feel excited, surging unceasingly. "Full virtualization, why not?" ” Chatting recently with a friend who has worked in the desktop virtualization industry for many years, he talked about the growing number

Nicira network virtualization architecture: Is it the online version of VMware? 1) It introduces network virtualization released by Nicira this month, and its relationship with OpenFlow. This article will continue to introduce how Nicira abstracts physical networks? Major customers of Nicira network virtualization. How do you abstract a physical network? Is OpenF

1. Can a virtual machine run any version of Windows on a specific server?Server Virtualization has no version restrictions on the Windows Server Operating System (or Linux) that you use on each virtual machine. However, the new version of Windows requires you to check its compatibility with your server virtualization software before installation.2. Will restarting a virtual machine affect other virtual mach

Abstract:This article is an interview with Bruce Eckel and Bill Venners on C # chief architect Anders hejlsberg. In this article, you will be able to understand why C # declares a non-virtualization method by default, instead, we adopt solutions opposite to those in Java and C ++, all of which are related to version control and method coverage. Default non-Virtualization Bill Venners:In Java, the instance m

As the use of terminal virtualization and application virtualization increases, IT managers must realize that server requirements may change significantly because the virtualization technology selected for application delivery is different. Traditional non-virtualized application delivery requires applications to be installed on a physical server, and end users c

When network virtualization is insufficient to solve the problem Consultant Glen Kemp shared a case where a customer re-evaluated the benefits of network virtualization after encountering a platform Bug. Iteration of any new technology or existing technology will make events faster, cheaper, or less costly. Server virtualization will certainly produce these resu

Overnight, the IT industry seems to have achieved a leap: From virtualization to the cloud computing realm, we have always seen the blue giant of IBM in this evolution, from the industry's first application virtualization mainframe, to the current IBM has the most complete and advanced virtualization solutions in the field of

First, XenServer 6.1 introduction Citrix XenServer Server virtualization systems make data centers more flexible and efficient through faster application delivery, higher availability and utilization of IT resources. XenServer provides the advanced functionality required for critical workloads (operating systems, applications, and configurations) without sacrificing the ease of operation required for large-scale deployments. With unique streaming tec

Do you want to virtualize 95% of your production servers in a year? The following is the experience of implementing virtualization by the chief technology officer of Transplace, a logistics company. His company did not initially have any virtualization technology, and later, the company's mission-critical applications were running on virtual machines. Many CIOs want to know how far they are from applicatio

Virtualization is undoubtedly the biggest computing trend in the past decade. By separating the elements of different computing platforms, more and more enterprise users have moved to virtual machines in the "one application, one server" mode to fully realize the potential of servers and staff. Ignoring the benefits of virtualization is not a choice in any competitive industry. Unfortunately, in fact, many

Docker: a dark horse in the field of server virtualization Speaking of the question of server virtualization (of course, this is the core of this Article), we will inevitably focus on the core of VMware and Hyper-V, the relatively weak Xen and KVM are also often mentioned. However, today, a dark horse has entered this field with the power of thunder and lightning, and it cannot be used together with many tr

On mobile devices, the need for virtualization is growing. One is that mobile device configuration is getting higher, and some high-end configurations are close to desktop devices, which lays the groundwork for virtualization and, second, a growing diversity of user scenarios for mobile devices. Mobile devices are now not only used for entertainment, but also for work; third, security and privacy issues are

Device Simulation Hypervisor provides a way to share CPU with multiple operating systems (CPU virtualization), but to provide complete virtualization, the entire environment must be virtualized for these VMS. Machine-or platform-simulation can be implemented in several ways. One popular open-source package supports many hypervisor, calledQemu. Qemu is a complete simulator and hypervisor. However, KVM only

As file storage virtualization (FSV) is booming, the company has invested 60 million of dollars in the first two days of its acquisition of Nuview, which has since entered the field of file storage virtualization, and a large number of vendors have flocked in. Although the technology gives users a lot of anticipation, users are still concerned about the emerging technology. Vendors with this technology cla
