Run VirtualBox on Ubuntu 14.04 Cloud Server Instance - Yeah, Virtualization within Virtualization! It is actually possible to install and run. When we run virtual machines with VirtualBox on computer, normally we use the VirtualBox GUI to manage the virtual machines - like we shown in the guide to run Ubuntu on MacBook Pro. but a server does not have a desktop environment unless we specifically … [Read more...]
Virtualization and various virtualization related technologies has been explained including hardware virtualization, Software virtualization.
WordPress Local Development with Vagrant
Here is a Guide For Wordpress Local Development with Vagrant. Vagrant is Better than MAMP, WAMP or XAMPP for localhost development and is related to Virtual Appliance. Usually, we used to install WAMP or XAMPP, which gradually got backdated with the advent of Virtual Appliances. Now, Wordpress Local Development with Vagrant, is almost as the most advanced setup. Wordpress Local … [Read more...]
HipHop Virtual Machine (HHVM)
HipHop Virtual Machine (HHVM) is a process virtual machine developed by Facebook, serves as an execution engine for PHP, based on JIT. HipHop Virtual Machine (HHVM) is an Open Source Software like PHP. We can install HipHop Virtual Machine (HHVM) on the top of Nginx Web Server Software, that is the basic importance to know about HipHop Virtual Machine. HipHop for PHP (HPHPc) was also developed by … [Read more...]
Docker and Virtualization
Docker is not a complete virtualization technology, but has features that, if developed; could compete in hypervisor such as VMware. When we talk about virtualization, always we include the classic examples of hypervisors such as VMware and Hyper-V and, although less frequently; technologies like Xen and KVM. In this list of virtualization technologies, almost never include Docker and the … [Read more...]
What is GlusterFS?
GlusterFS is a distributed file system, the memory elements are presented as a single file system from a plurality of servers or nodes. The various servers even nodes, form a client-server architecture over TCP / IP. A distinctive feature from NAS systems is that, a redundant connection of storage devices over TCP / IP is possible. The data on all the cluster nodes can be read and written at the … [Read more...]
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

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...]
