Oracle Is Latest To Take On VMware

BobB writes "Oracle is going after its piece of the hot virtualization market by introducing an open source Xen-based hypervisor to compete against those from Novell, Red Hat, and VMware. Oracle VM, unveiled Monday at the Oracle OpenWorld convention in San Francisco, enables virtualization on Oracle and non-Oracle software applications and on the Linux and Windows OSs. It also operates on industry-standard x86- and x86-64-based servers. Oracle claims it offers virtualization at a lower cost than competitors can." VMware stock dropped over 10% on the news; Oracle's stock rose. The market was not punishing Oracle for the unpatched zero-day vulnerability (public exploit available) that the company won't patch until Jan. 15.

I can't see the link between a Xen-based hypervisor and and a company being punished for a "unpatched zero-day vulnerability" that doesn't look like it is part of the hypervisor. Also, I can't see why the stock price would drop based on critical bugs. Stock prices should reflect number of people buying the software anyway. Hence Microsoft stock have value.

No stock prices reflect the number of people who want to buy the >stock as compared with the number of people who want to sell it. Stock prices may have nothing to do with the viability of the products and services the company sells (at least in the short run). That's why there was a dot com bubble in the first place.

Re:

At the lowest level you are correct. However, what is the reason for people wanting to buy the stock vs. sell the stock. Sure what it really comes down to is that they believe that they will be able to sell the stock for a higher price at some later date, but there has to be some product behind it, or it will eventually collapse, like the dot com bubble.

People actually thought all those dot com companies were worth something, and had a chance of selling some kind of product, otherwise, they would have never bought the stock in the first place.

You give people way to much credit. I agree that people thought the dot com companies were worth something.

There are at least 2 groups of people here though:

The first group though the company they were investing in had a product they would be able to sell and be profitable.

The second group simply saw the value of the company as being the rising stock value. The second group didn't have any idea what the product they would sell might be, or how viable it was. The second group most likely caused the bubble

retarded comments in summary

[timmarhy]

Please try to keep stupid statements like "The market was not punishing Oracle for the unpatched zero-day vulnerability (public exploit available) that the company won't patch until Jan. 15." out of the summaries. the market is NOT a technical forum, so unless this exploit can demonstrate some kind of loss for oracle, they have no reason to "punish"

And why would we expect the market to "punish" them? Does anyone actually expect it to cost them sales or other revenue, or increase their costs, or otherwise have a relevant impact on their financial status?

Exactly. Unless a massive worm can exploit that security hole and deletes a few billion dollars worth of data, I doubt that it will have any impact on Oracle's bottom line.

Company performance should effect investors.

[RingDev]

To be fair though, the market value jumped because they announced a new product. If those investors were aware of the total and complete 'shittiness' of their existing products (hell, 11 freaking versions and the interface still sucks donkey balls, unpatched exploits, etc...), they may not have been so interested in the new product.

It may not be bad for consumers in general, but for Oracle customers it limits choice.

Re:

Not due to linux, nor virtualization. In fact they have probably gained a lot from linux, and why not? The less someone spends on their operating systems, the more they can spend on Oracle licenses.

They may have lost a few sales to MySQL and PostgreSQL, but that's no reason to attack linux or Xen.

Re:Can they compete?

[martyros]

I think this quote from their Oracle VM FAQ is more telling:

Recognizing enterprise customers' demand for fully supported server virtualization, Oracle now offers Oracle VM backed by a world-class support organization, as well as a full suite of Oracle product certifications.

In other words: they recognize that customers want virtualization. But, they don't want to support running on just any hypervisor. Doing so places them in the position of having to rely on another company's software product to run well, which is just not a good idea from Oracle's point of view. The solution? Take an open-source solution and tweak it to their own specifications. Since they have control, they're not dependent on anyone else for good performance.

They claim to do Windows virtualizaiton, but the fact is that without paravirtualied Windows drivers, any performance is going to royally stink. I'd be surprised if they invest the time to actually make those work.

What would be a good idea for them in the long run, I think, is to allow their management tool to integrate with some others -- RedHat's or XenSource's, for example -- so that customers can manage all their servers from one console, while taking advantage of Oracle's specialized distro.

Re:

Yeah, me too. I spent some time at Oracle and while marketing paid lip service to the Microsoft stack, the division that did projects couldn't be less interesting.

I wasn't really clear, but I was working at the time in the business unit that did projects (for hourly rates) for customers. So there is no lock-in argument there.

The only reason I can think of, and have see companies do, is for VMotion fall over. Install an ESX server with just the DB running, and if it has problems, or you need to take down the physical box, you just move it to another one temporarily, without a break in transactions. Works well, but that is the only reason I can think of for doing it.

Re:

[iperkins]

Exactly. Fault tolerance. if the physical server tanks, you move the image to another box. This can also eliminate downtime due to hardware maintenance. Move the image to another box, take the physical box down, do what you have to do, bring it back up and move the image back. This can be done during normal hours - no waiting for nights/weekends, which makes the IT staff happy.

Re:

[Donny Smith]

>Exactly. Fault tolerance. if the physical server tanks, you move the image to another box.

Bzzzz! Wrong.
There's nothing to move here - the OS and/or database remain on the shared storage, the OS can optionally be started on another box.
(Apart from this, Oracle already has built-in RAC clustering which does not depend on 3rd party fail-over solutions for fault tolerance of database applications.)

That's because CentOS isn't competing with Red Hat. Red Hat's market is the enterprise customers that *will* pay tens of thousands of dollars per year for support, and this is exactly the same market Oracle is catering too with Unbreakable Linux. CentOS is for users that can fix problems on their own and/or cannot afford an RHEL license. This is not the market Red Hat is aiming for.

Re:UnFAKEable Linux

[Anonymous Coward]

Oracle aren't competing with Redhat either. Someone would actually have to be running Unbreakable Linux for them to be competing, and I haven't seen anyone doing it yet: if anything, the market seems to have treated Oracle as a slightly embarrassing uncle who wants to convince you that he's still "hip and cool" and can do Linux just as well as that upstart Redhat can. They just sort of wish they'd be quiet, go home & stick to what they know.

The idea of Oracle supplanting VMWare in the enterprise virtualisation market is even more laughable. No one is rushing to replace VMWare with Xen, and if they were, they wouldn't do it through Oracle. Oracle make databases (Oh and they do middle wear now too. Buying WebLogic was a rare smart move, provided they can stop JBoss commoditizing their market) Honestly though, Oracle should leave the rest of the software stack to the rest of the industry.

Re:

[ckaminski]

Yup. And the same thing was said about Linux 6 or 7 years ago. Look where we are now...

VMWare blazed a path on Intel based hardware, that's for certain. Their only main way to keep their lead is to push the tools better and faster than Xensource (Citrix). Hardware-based paravirtualization saved Xen from having to implement VMware's code morphing; it's a level playing field and they only benefit to VMware at this point is the robust toolset.

Citrix has years of experience at building management toolsets.

Actually Oracle's VM is much more akin to the xenserver product from citrix or ESX from vmware. Its not a hypervisor that runs on an existing OS, it is a stand alone OS. Oracle's VM is not a rebrand of RHEL this time. And btw, I'm pretty sure oracle's "unbreakable linux" (the red hat clone) already has Xen as a virtualization option, as it is based on RHEL 5 which includes Xen (even in the 5.0 release).

There's probably more here than rebranding. Oracle has the resources to create their own Xen-based solution, and is certainly not going to rely on Red Hat's work.

That said, you're right to wonder at all the reaction to this announcement. Everybody and his dog are doing virtualization solutions, and the Oracle version is hardly groundbreaking.

for Oracle to get into the VM business.

Then they can ship pre-built VM images with oracle already installed and configured. Thus, the database server becomes a VM appliance (not quite a dishwasher yet...)
Easier to support (ie lower costs) especially if the VM runs Linux. As much as I hate Oracle, this following their 'legal theft' of RHEL it all starts to hang together.
However, it remains to be seen if they can build up their support side so that is basically 'sucks less' than it does now. There is a danger that they are spreading themselves too thin.

I don't think VMWare should get too worried by this. The overall market for VM's is huge. As long as the quality of their product stays high then their market will grow along with the overall market for VM Systems.

 

Sorta makes sense to worry too

[cumin]

One of the major selling points for VMWare is that it is ideal for development and if a major player in the development world, which Oracle is because they have the database, then there is much more appeal and legitimacy to doing virtualization through Xen. Now, personally I just got our company to buy a VMWare license for a couple of us because it is so easy and we're working with Macs. The issue wasn't a question of which VM system was better, it was a simple question of which was cheaper. I preferred VMW

With a VMWare machine all communication with the processor must be interpreted, that is how the machine essentially works, it provides a fake communication channel that it can control. It does a really slick job of that, but it is still having to go through the extra step.

Not so with Xen, because it uses modified kernels that don't have to be interpreted (Which is why you can't just install your favorite OS in any old Xen like you can with VMWare.) This is why

This was definitely true in the days of VMware code morphing where every kernel transition caused many extra thousands of CPU instructions. This is not necessarily true today in a hardware-assisted virtualization world.

I'm guessing the reason for your poor DB performance was due to disk access. In vmware you can use a real partition rather than a disk image, not sure if you can with Xen.

[MartijnL]

Yadda yadda, if Oracle doesn't fix it's own licensing policy than they still will be looking to take you hard for database licenses. They don't recognize software partitioning as a valid means of buying less licenses than there are CPU's in the physical box and when you run VMware in a cluster they want you to license your whole cluster.

VMware support by Oracle

[Jugalator]

On this topic, Oracle also refuse to provide support for Oracle installations on VMware hosts.

I wondered why that was so, because VMware provides a common emulated hardware foundation, and logically ought to be *easier* to support than the wild variety of actualy physical hardware out there.

Anyway, now I know why.

you're probably right

[alizard]

I've managed to run Windows 98SE stably and reliably in Win4Lin 9.x on a Fedora Core host and VMware Server on a Debian host, though this is a desktop, not a server environment.

If virtualization can stabilize Windows 98, I'm sure that it can provide any help with stabilizing Oracle it can possibly use. If I had to run Oracle, I think I'd look for third-party support for Oracle and thumb my nose at Oracle Corp in the hope of getting more uptime than I can get with a native Oracle environment.

I'm not the DBA here, but we have most of our Oracle servers running on Redhat ES on VMWare ESX 3, and they're perfectly fine. Which is exactly what you'd expect, frankly.

I've not heard that Oracle refuse to support systems installed on VMWare though. I think the last time we actually tried to get support from Oracle was, er, never. Our developers report bugs to them, and that's about it.

I suspect that if their refusal to support is true, then it's for bullshit reasons. Exactly what you'd expect from a

Expect non-support-except-on-our-VMs to be normal

[swb]

All the major application vendors recognize that VMs are valuable and they also recognize that by refusing support for 3rd-part VMs *AND* offering a VM (even if it is someone else's with a new paint scheme), they can both make more money and squeeze competitors. Microsoft is already doing this with Exchange 2007 (note coming hypervisor/VM tech in 2008 server), and I expect other major application vendors might try the same thing.

This is clearly a monopolistic practice, but I don't expect our corporate over

Oracle Is Latest To Take On VMware

Please - Xen does not a vmware copy make - vmware is so much more than a virtualization product, VMware are trying to make it THE datacenter management tool.

I wish I could give you mod points. :( I think VMware did a great thing bringing virtualization to the intel platform. They did a hard job. But Intel and AMD lowered the cost of entry. With Open APIs, Xen is only going to get better, and the management tool experience that Citrix brings to the table will only increase it's penetration into the datacenter. Everyone knows Citrix already, soon it will be a tough competitor to VMware. Two years. This will only benefit us all, as the trickle down effect

10% down? Sounds good.

Looks like a nice opportunity to buy some VMW stock.

A lot of customers want this

[ChrisA90278]

Why is Oracle getting into so many new markets? I think it adds value to some of their customers. The reason is service contracts. Many companies will not buy software unless they can also get service with it. What they don't like is having to buy 15 different service contracts and then watch the various vendors all say "The problem is in the other guy's stuff, ours works fine." These customers want a single point of contact for software problems and Ocracle wants to be that single point.

Boo Oracle

[billcopc]

Aside from the trendy corporate bashing that happens when any billion dollar crackpot-led company is on the menu, I lost all faith in Oracle the day they deprecated the term "database" in favor of "application platform", and added a couple zeros to the price.

Oracle, much like Microsoft, has lost its purpose. They absorb, invade and cheapen every single area of computing with their predatory acquisitions. It used to be that Microsoft was an OS company, and Oracle was a DB company. Oh, and Google was a sea
