CIOs Are Discovering That Containers Might Be The Right Way To Ship Code

The Accidental Successful CIO

In order for the software to operate correctly, the supporting software in the environment has to be identical to the software that was present when the software was developed. By contrast each container shares the operating system kernel with the other containers.

Critical Xen hypervisor flaw endangers virtualized environments

Network World

A critical vulnerability in the widely used Xen hypervisor allows attackers to break out of a guest operating system running inside a virtual machine and access the host system's entire memory. This is a serious violation of the security barrier enforced by the hypervisor and poses a particular threat to multi-tenant data centers where the customers' virtualized servers share the same underlying hardware.

Talking Containers, Virtualization, and Interop

Scott Lowe

and as a returning speaker I recently had the opportunity to do a podcast with Technology Advice about SDN, virtualization, containers, and Interop. Companies are applying the “SDN” term to everything from using a Linux-based network operating system (NOS) on their hardware to adding APIs to existing proprietary NOSes or providing virtual appliances of their software. Last year, I had the pleasure of attending and speaking at Interop for the very first time. (I

2013 may FINALLY be the year of VDI and BYOD

Virtualized Greek

I am thinking that maybe 2013 will finally be the year of virtual desktop infrastructures (VDI) enabled BYOD. This means that basically, just like Hyper-V the hypervisor is native to the operating system. This allows a user to checkout an offline version of the virtual desktop.
