VMware makes a strange move

Every day the battle in the virtualization market is getting more exciting. 

Thursday (11 December 2008) VMware released update 3 for it’s free hypervisor: ESXi. No big deal right?But apparently they changed something in this update that could really change the way VMware virtual infrastructures will look like in a few months / years. 

In the last 12 months we have seen a change of focus within the virtualization battle. The hypervisor has really become a commodity and is free (ESXi & Hyper-V). It’s all about managing the virtual infrastructure now. Microsoft released their System Center Virtual Machine Manager (VMM) for this. What makes VMM great is that it can manage different virtual infrastructures at only a fraction of the cost of other managing tools. VMM can also manage a VMware VI. The downside of this is the fact that although you can manage a VMware environment you will also need VirtualCenter. VMM needs VirtualCenter to pass the command to the ESX servers. So you would need double the licenses for management software for your VI. Smart move from VMware, because they are actually making their money with the extra features that VirtualCenter brings.

But with update 3 of ESXi, VMware has decided to fully unlock all API’s. This means that any virtual machine managing tool can perform Vmotion activities on a VMware VI. This really diminishes the need for VirtualCenter. VMM would be able to perform the most important management tasks. For medium sized environments this would definitly be enough. You will have a stable hypervisor for free (ESXi) and the management tools for nearly nothing (VMM). 

I’m sure VMware has thought about this as well and is convinced about the business case for VirtualCenter. I hope they or anyone else on this blog will share this soon with me.

Update:

Well this explains everything. 

 ”Turns out that while fixing an API bug the API set got partially unlocked. Yes, you read that right, VMware didn’t mean to unlock the API set - at least not wholly and not yet. So, if you went out and started madly coding some killer VirtualCenter Client replacement then hold off because I’m told the U4 update will lock things back down again”

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Nano Technology With Nokia Morph

Nano Technology has evolved as an all together different technology area in the mobile world. Mobile phones are advancing at a great and faster pace than never before and Nokia Morph is truly a mobile wonder. This phone has been developed by Nokia Research Center and the University of Cambridge (UK). The Morph specialty lies in the design and technology used to make it possible. The best part of this phone is that you can transform it according to your wish and that what exactly Nokia wanted to come up with- Flexible and Reliable phone. You can radically change the phone in different shapes one of being the bracelet way. Professor Mark Welland, Head of the Department of Engineering’s Nanoscience Group at the University of Cambridge and University Director of Nokia-Cambridge added, “Developing the Morph concept with Nokia has provided us with a focus that is both artistically inspirational but, more importantly, sets the technology agenda for our joint nanoscience research that will st...

Compal's 'Ultra Mobile' Ultrabook eyes-on

Intel's already teased Compal's "Ultra Mobile" Ultrabook from afar, but when this Ivy Bridge laptop popped up on the show floor after the Computex keynote, we decided to give it a closer look. While this prototype isn't quite in the same league as ASUS' gorgeous UX21, do bear in mind that we're still looking at a relatively slim package for a 14- to 15-inch Core i7 rig. Also visible around the machine are a couple of USB 3.0 ports, an HDMI-out port, a LAN socket, and an SD card reader. Until we hear more about this Ultra Mobile, enjoy our eyes-on photos below.
