Bromium release vSentry 1.1: trustworthiness for more desktops in the enterprise?

PresentationVirtualizationBromium have released vSentry 1.1 which will brings Bromium’s benefits of micro-virtualization and hardware based security to a far wider range of enterprise desktops. This is the release you’ve been waiting for: and if you’ve not been waiting, this is definitely the release to consider.

We’ve spoken before about Bromium when they unveiled their micro-virtualization trustworthy security vision. Bromium’s message and focus was simple “standard workspace security is reactive, not proactive“. Whatever you have in terms of anti-virus or malware detection is only good once a new threat is found,  understood,  a patch created and deployed. This poses the very important question “what is the impact of the time delay between threat found and threat contained?”.  Bromium’s goal was to dramatically reduce that “and”.

You may contest, “ah, but I can solve this workspace threat issue by making physical desktops, virtual desktops”. This is not the case. We evidenced this in Virtual desktops (VDI) are different, but not hugely better in terms of security, than physical desktops. You do not deliver better security by simply virtualizing the desktop.

So what does vSentry v1.1 bring? How is it better than v1? What can this mean for your organisation?

Windows 2012 Hyper-V – the hypervisor for your Cloud? Part II

DataCenterVirtualizationWindows 2012 Hyper-V is the hypervisor for the cloud, VMware’s vSphere is a dead man walking?

In Part I I shared a chunk of what I learned from Aidan Finn‘s enlightening and entertaining session delivered at the E2E Virtulisation Conference in Hamburg tastefully titled, “Windows Server 2012 Hyper-V & VSphere 5.1 – Death Match”. In Part I we looked at pricing, scalability and performance, as well as storage in questioning how bold this statement was.

Pure license-cost wise, it more straightforward to run Microsoft Hyper-V than add another licensed hypervisor: note that Hyper-V does have a free offering (although this version doesn’t cover the virtual Windows Server instance licenses). We showed that scalability wise, Hyper-V can better common competition. Storage-wise Hyper-V, as should be expected from the newest offering, supports the newest technology: 4k sector sizes, and had the largest virtual disk support. Still, if you needed greater than 2TB of storage, you could always join multiple 2TB instances together, or bypass limits by mapping a LUN direct to the VM.

Still, besides pricing simplicity, performance improvements, and updated storage what has Microsoft done for the latest version of Hyper-V? In Part II, lets question further Aidan’s premise that Hyper-V kills vSphere.

Project Avalon: Will Citrix Put VMware Horizon to the Sword?

Project Avalon was announced by Citrix back in May. Project AvalonAvalon is to deliver Windows apps and desktops as a true cloud service. Since then, there has been speculation on what that actually entails. “Cloud” or “Cloud Service” can have many different connotations; indeed, for many the very term “cloud” fills their ears with a high-pitched nee and causes a yearn to live in an anarcho-syndicalist commune.

Running small-scale, departmental-level deployments of desktop virtualization is relatively straightforward. Scale past thousands to several thousands of desktops and applications, and the process of management and delivery gets much harder. More importantly, data centre technology has changed. How do you scale an environment while segregating the roles of a virtual desktop administrator from those of the storage, networking, or virtual infrastructure teams? How can the data centre infrastructure team provide the right service to the desktop team, and vice versa, so that they can optimize delivery of virtual desktops?

Citrix has FlexCast, the concept that IT should be able to deliver a variety of types of virtual instances, with each tailored to meet performance, security, and flexibility requirements. But while FlexCast gives choices for users, the simplicity of the user interface belies the rapid duck-paddling of disparate, separately developed and maintained products that organisations have to maintain at the back-end, many of which creak at the mere thought of a little bit of scaled peril.

To avoid smelling of elderberries, Citrix needs to make the administration and deployment of their Windows application and desktop delivery more straightforward and relevant to current delivery methods. Easier large/massive deployments are necessary in order to maintain large enterprise account revenue and to entice service providers to build solutions on Citrix software. Project Avalon is intended to allow organisations to effectively centralize IT to provide cost savings through scale and administration and maintain security, while enabling decentralized IT resources to utilize those central services to give users and customers a productive experience.

At the same time, the VMware Horizon Suite is intended to provide the end user with a single place to get access to their applications, data, and desktops and to give IT a single management console to manage entitlements, policies, and security.

At Synergy 2012 in Barcelona, components of Project Avalon were revealed. Project Excalibur will focus on creating an integrated FlexCast platform, and Project Merlin will deliver self-service provision, management, and service orchestration.

What will these components provide, and where will it lead customers? Will embarking on a quest to get to Avalon lead to the promised grail or just to some watery tart?

VMware’s Application Management Strategy

When we think of VMware, we usually think of vSphere, VMware’s market leading data center virtualization offering. Data center virtualization is infrastructure software, concerned about applications only to the extent that they consist of workloads running inside of guest operating systems or virtual machines. However, there is an entirely different side to VMware, one focused on applications. This focus includes application management, application monitoring, and development platforms for next generation applications. This post will deal with the application management piece.

Citrix Remote PC: VDI complexity solved, or a kick start to a VDI project?

synergyAt Citrix Synergy in Barcleona, I got to have a look at Citrix’s latest addition to the FlexCast technology stack, Citrix RemotePC. Citrix RemotePC was released as part of Citrix XenDesktop 5.6 Feature Pack 1. While XenDesktop is Citrix’s hosted desktop solution, but Citrix Remote PC is not a virtualised desktop. Citrix Remote PC is secure brokering of a physical Windows endpoint (be that a desktop or a laptop) in your office, via Citrix’s HDX technology.
