Benefits of application virtualization

Benefits of application virtualization

With application virtualization, it is possible to run an application that is not installed on the work station from the very same work station. This technology isolates applications from the underlying operating system and other applications in order to achieve greater compatibility and mobility of the applications.

The most significant advantages of application virtualization are:

• Reduction of maintenance needs: there is no need for maintenance, installation or uninstallation of applications in the local PC.

• Availability of the application at any time and in any place. You only need to have network access and a compatible device (PC, terminal, laptop…).

Security bug found in Xen hypervisor

Security bug found in Xen hypervisor

A vulnerability in Xen hypervisor has broken the security around multi-tenant environments. It allows Xen hardware virtual machines (HVM) to access data storaged in other HVM-based machines that are located in the same hardware. This bug, which has been registered as CVE-2014-7188, also allows to crash the host.

ARM systems and paravirtualization servers (PV) of the Open Source hypervisor haven’t been affected. The only vulnerable systems are x86.

Xen Project has published a patch to solve this problem, which affected big companies, such as Amazon or Rackspace, that had to reboot their virtualized servers.

Linux Foundation launches Open Platform for NFV Project

Linux Foundation launches Open Platform for NFV Project

Linux Foundation is moving forward in the telecommunications sector. This week they have announced the birth of an Open Source platform that aims to speed up the introduction of new products and services thanks to Network Functions Virtualization (NFV). This project is called Open Platform for NFV (OPNFV) and it is supported by vendors and telecom operators, such as AT&T, Red Hat, HP, Cisco or Citrix.

This new initiative will accelerate the delivery of cloud-based models to operators, enable interoperability and will accelerate standards through an Open Source reference platform.

New software defined storage platform

New software defined storage platform

Most SMBs find really difficult to afford server virtualization costs. That’s why HP has launched a new software defined storage alternative (SDS). The company will give free licences to its clients for more than 72 petabytes SDS capacity.

The only requirement to join this program is to purchase an Intel Xeon E5 v3 processor. After the purchase, a 1TB HP StoreVirtual VSA software licence will be obtained.

This software allows implementing the SDS with a deployment of shared storage which adapts itself to the virtual server that executes Linux Kernel Virtual Machine, VMware or Microsoft Hyper-V.

Major vulnerability found in bash

Major vulnerability found in bash

A major vulnerability has been discovered that targets bash, the Unix system (including OSX) and Linux commands interpreter. Apparently, this security flaw is also affecting other interpreters, such as ksh, tcsh, zsh and csh. Nevertheless, other shells aren’t being affected.

UDS Enterprise servers aren’t vulnerable to this fail, so the security of the virrual machines which provide UDS Enterprise remains unaltered.

This vulnerability has been registed as CVE-2014-6271 and it allows to execute certain commands due to the wrong process of the environment variables. Besides, it may be exploited remotely.
