Virtualization

Virtualization and various virtualization related technologies has been explained including hardware virtualization, Software virtualization.

What is Hardware-Assisted Virtualization

Hardware Assisted Virtualization is also known as native virtualization. This is an approach to full virtualization in extended condition, wherein the processor provides the architectural support to facilitate the construction and the hypervisor forward calls of different guest operating system directly to the physical hardware, increasing the overall performance of the system. Xen hypervisor, … [Read more...]

What is Container Based Virtualization?

Container Based Virtualization is as an advanced implementation of the standard chroot mechanism where we get more advantages in addition to isolation mechanisms. Those who are the regular readers of this website, obviously has noticed articles on Docker. We want to make this Docker part clear to the readers. Also, possibly you have read about VirtFS or Jailed Shell. This Jail (which we … [Read more...]

What is VirtFS or Jailed Shell?

Jailed Shell or VirtFS is a paravirtualized filesystem based on the VirtIO framework often used by Shared Servers to protect the other users. We talked briefly about paravirtualization, KVM here is Kernel Based Virtual Machine (there is another KVM - which is a switch), SSH to Shared Hosting Server etcetera topics. Jailed Shell is a wider topic which includes a rightly defined, protocol based … [Read more...]

Software Defined Data Center : New Business Opportunities

Software Defined Data Center (SDDC) can be a mainstream business over next few years, it is always better to be attentive to innovations. Previously, we talked about Why Software Defined Data Center is Emerging, What Purpose Software Defined Data Center Serves and the basics - What is Software Defined Data Center (SDDC). So the basics around the thing has already been defined through these … [Read more...]

Hardware Description Language : Structure and Simulation

Hardware Description Language is a formal language for the operations of integrated circuits, their design and software based simulations. Hardware description languages ??express a temporal behavior and/or a (spatial) Circuit structure in normal text. Unlike software programming languages ??HDLs include syntax and semantics in their notation to express temporal sequences and co-existences. … [Read more...]

What is Network Virtualization?

Network Virtualization combines the hardware and software network resources and functionally converts to a single administrative entity. Several newer technologies are in the promising list to increase network agility, like Network Virtualization (NV) which we are talking about, Network Functions Virtualization (NFV), and Software Defined Networking (SDN). Network virtualization often combined … [Read more...]

Adaptive Domain Environment for Operating Systems

Adaptive Domain Environment for Operating Systems provides a flexible environment for sharing hardware resources for operating systems. Adaptive Domain Environment for Operating Systems is usually abbreviated as ADEOS. Adaptive Domain Environment for Operating Systems is a hardware abstraction layer (HAL) or a hypervisor that operates between computer hardware and the operating system that runs on … [Read more...]

What Purpose Software Defined Data Center Serves?

Software Defined Data Center (SDDC) is easier and cheaper to deploy IT resources - one can think it as one level up from typical IaaS. For some Software Defined Data Center is old wine in new bottles, for others a small revolution. It is assumed that the reader has the basic idea about Software Defined Storage Virtualization. Actually whether VMware vFabric will be used or any new software yet to … [Read more...]

Types of Apache 2.4 Virtual Hosts : Name-Based, IP-Based, Port-Based

Three Types of Virtual Hosts are Explained - Name-Based, IP-Based, Port-Based. These Terms Often Create Misunderstanding to the New Users. Right now, we should be talking about Apache 2.4, because there will be some difference in the manual of Apache 2.4 versus Apache 2.6. Types of Apache 2.4 Virtual Hosts, should not be confused with terminologies associated with core of Virtualization, such as … [Read more...]

How to Detect Application is Running within a Virtualized OS Instance

How to Detect Application is Running within a Virtualized OS Instance - the fact is that the virtual machine is not an entirely the accurate representation of a real dedicated system. You got the point! A virutalized OS is a kind of 'second' OS on a machine. This means that the resources needs to be shared.   How to Detect Application is Running within a Virtualized OS Instance : … [Read more...]

ReactOS on VirtualBox : Free Windows Like OS on Mac OS X, Linux

ReactOS on VirtualBox Mac OS X or Linux works like Free Windows OS which allows the user to use any Microsoft Windows Application fully Free of Cost. Here is Full Guide. Previously we wrote about ReactOS in brief. ReactOS is fully legal, Free Operating System that comes under GNU GPL 3.0. Unlike Microsoft Windows, it is not a closed source software and fully free. On Mac or Linux, you might need … [Read more...]
