See You at Camp! CloudCamp, That Is!

September 30, 2008 Leave a comment

For those of you lucky enough to make the CloudCamp Silicon Valley cut (registration is full, except for a few lucky souls who attend SDForum’s Cloud Computing and Beyond conference on Wednesday), I look forward to meeting you. I am especially excited about connecting with folks like Geva Perry, Lew Tucker and Franco Travostino, but the entire field looks amazing. (Take a look at Franco’s latest paper to see why he’s on my list.) It should be a heck of an evening.

I’m hoping to present briefly about what the Stored Communications Act, the Patriot Act and Steven Warshak vs. United States of America are going to do to undercut any technical innovation in the cloud by U.S. companies.

Regardless, stay tuned for my report on the event soon afterward. My schedule has been packed lately, with my work at Alfresco combining with increased responsibilities at home to create a perfect vacuum of blogging time. However I have a couple of what I hope are really good posts in the works, and may have time to get caught up later in the week. In the meantime, I’ll continue to send links on my feed.

By the way, I am trying Diigo now for bookmarking, and they are supposed to have the best support for posting links to Blogger. However, while I can get manual posts to work, the automated daily feeds are failing without error (much as they do with the experimental daily blog post). If anyone can help me figure this out, it would be greatly appreciated. I’ll check the comments on Discus (see below) and FriendFeed, so feel free to post either place. Or, contact me directly at jurquhart at yahoo dot com.

Oracle Joins The Cloud–But Does It Their Way

September 22, 2008 Leave a comment

Interesting news this morning from both the Oracle and Amazon camps: Oracle has made available licensing for a broad swath of their infrastructure products to run in the cloud. More importantly, they have made Amazon EC2 AMI’s available for Oracle 11g, Oracle Enterprise Manager and Oracle Fusion Middleware are available for free on EC2 right now. Amazon’s Jeff Barr also hints at another interesting announcement:

“And if that’s not enough, Oracle has also unveiled a new Cloud Management Portal. This is a free, web-based way to manage Oracle software running in the cloud. “

I can’t find any more details about the portal at the time of this writing, however.

It is interesting that Oracle is trying to create the impression that it is entering the cloud computing business from their press release (“Oracle Joins Cloud Computing”)–seeing that NONE of the products listed are cloud products, per se. They are all traditional infrastructure products than can be used to enhance applications that happen to run in the cloud, but they do not provide a cloud, or even “cloud enable” applications. (The portal *may* run in the cloud, but it is not cloud infrastructure in and of itself.)

Then again, it’s not surprising to me that Oracle chose to go this route. Remember their reaction to SaaS? Oracle maintains that traditional perpetual licensing and enterprise sales is the foundation of their business, and that the economics of SaaS just aren’t compelling enough to change. (Of course, the Cloud Management Portal would be an interesting exception…but it turns out to be free.) Thus, the logic route for Oracle is not to become a Cloud OS provider or some such thing, but rather to sell their software into the cloud…which is exactly what they have done.

The cost of Oracle in the cloud may be purely support based, if I read Jeff’s post correctly, but I’d stay tuned for more on that. My gut feel tells me there is more to the licensing story than is available at this early stage.

9 Sources of Cloud Computing News You May Not Know About

September 20, 2008 Leave a comment

I’m a cloud junkie, as most of you know, and I spend way too much of my time perusing feeds and lists for content that sheds light on cloud trends and challenges. However, I have a secret; I streamline my looking somewhat by leveraging sites that aggregate amazing information into regular lists of stories. Below is a rundown of several of these lists, including a few that you may not have been aware of.

Please note that this is not a list of all of my favorite cloud computing blogs; I have scads of favorites that are not listed here because they are not “news feeds”, but rather pure commentary/analysis, vendor blogs, or technical errata. (The problem with categorizing blogs, however, is that many “news feeds” are filled with commentary and analysis as well…*sigh*.)

Without further ado:

  • Google Alerts: “Cloud Computing” | “Utility Computing”: Actually, I run these two terms in two different alerts, but the two of them are more than I can read most days. “Utility Computing” is rather light, but “Cloud Computing” often runs in the tens of posts/stories a day now.

  • Jian Zhen and Michael Mucha run this automated feed of cloud computing and SaaS related stories. The list is dense every single day, and is the quickest way I know of right now to catch on to the more subtle conversations going on about these subjects. It is also lightly (or even not) moderated, so be prepared for tons of “its all been said before” posts.

  • On-Demand Enterprise’s Cloud Computing Topic: The former Grid Today folks at Tabor Communications have really become a go to resource when it comes to vendor coverage, especially in the traditional enterprise data center software and virtualization space. Good analysis, complete coverage of announcements, and posting of entire press releases (which is very handy, believe me). Not quite as good for the theory stuff, though.

  • Avastu Blog: Sustainable Global Clouds: I just discovered Tarry Singhs’ excellent blog a few weeks ago. He somehow finds companies and stories that I absolutely do not find elsewhere. Tarry appears to be very well connected in the Indian venture capital world (and, I assume, the EU equivalent, as he states he is from the Netherlands). He also “gets” cloud computing.

  • GigaOm – Infrastructure: Of the “big” tech bloggers, Om Malik and his team get my vote as the most informed and connected in the cloud computing space. Yeah, they are largely telecom/Web 2.0 happy, but they clearly understand that there is less and less distinction between those markets and the cloud, and they regularly produce news items that make you think. Oh, and you can subscribe to just the Infrastructure feed, which is where most of the good PaaS and IaaS stuff is.

  • ZDNet – Software as Services: For the SaaS game, there is no one like Phil Wainewright for a combination of scoops and analysis. In fact, his analysis is so deep I thought of leaving him off this list, but in the end this blog makes me aware of too many new SaaS vendors, applications and services.
  • TechCrunchIT: Steve Gillmore’s new collaboration with Michael Arrington’s red-hot TechCrunch isn’t a “pure” cloud computing news source, but it scoops just enough that I thought I’d include it. Be prepared to wade through tons of politics and “Social Software” to look for the cloud computing gems, however.

  • Data Center Knowledge: Rich Miller’s blog is (for me) the source of two key pieces of intelligence in the cloud computing game: data center build-outs, and outages. Rich seems to find every single announcement about new or growing data centers, the companies planning to enter the cloud provider game, and the infrastructure challenges of the cloud. This is one of my favorites for sure.

  • The Wisdom of Clouds (RSS/Atom Feed): OK, a bit of shameless self-promotion, but for those of you who have arrived at this site via HTTP, and are not subscribed to my feed, it is important to note that I use Feedburner to publish my daily bookmarks. In addition, I currently use as my “quick blog” tool, and I comment on every bookmark I record there. Several readers have highlighted this as a favorite aspect of my feed. I am trying to get the “Blog Posting” feature working, so the same lists appear in the HTML pages (so they can be commented on, etc.), but so far no luck.

What are your favorite sources of cloud computing news?

Cloud Computing on Google Groups is Dead to Me

September 18, 2008 Leave a comment

Update: OK, I got a little emotional here. I am upset at the way this played out, but the title and some of the sentiment expressed are a little harsh. Perhaps, “Cloud Computing on Google Groups, I’m moving on” would have been more appropriate. Also, while I will be moving on (unless invited back), the group will no doubt remain active and interesting. Just be aware of how it is moderated–and be aware that there other venues in which to discuss cloud computing.


A couple of days ago, I reacted to a post by Sam Johnston outlining a scary exchange with the moderator of the Google Groups Cloud Computing group, Khazret Sapenov, in which Sam found himself locked out of the group with no public or private explanation. I wrote the post because I wanted Khazret and Reuven Cohen (also implicated) to have an opportunity to respond to Sam’s charges, and for the community to work this out fairly and openly. I considered the post a “reconciliation post”, nothing more, nothing less. (I will admit that I should have rethought the title, though.)

This morning, my first attempt to view the group home page resulted in this:

Now, here’s the kicker: I absolutely did not post a thing to the group between the time of the reconciliation post and when I was locked out, so I couldn’t have been locked out for a violating the group’s rules, whatever they may have been, unless there was a problem well before I posted. This reaction is almost certainly to the reconciliation post itself, which did not at all take place in the group threads.

Google Groups Cloud Computing is dead to me. It’s not even worth fighting this. I loved the insights of the group, but there are other viable communities to turn to that are open and transparent, and that can be considered credible. This group is none of those things, apparently.

To have two leading cloud computing bloggers locked out of a supposedly open community–without any public or private explanation–signals bias and dangerous politics.

Here is a little more detail:

  • Since I posted the reconciliation post, I’ve had three other emails confirming Sam’s claim that moderation has been strange, arbitrary and at times very slow. Not an overwhelming response, but significant enough to note that Sam is not alone in his thinking.

  • At the same time, I’ve had no emails or comments explaining what happened to Sam.

  • This morning, I received a comment from Reuven claiming that neither he nor Enomaly have had anything to do with the controversy, despite his founding of the group and (I would imagine) subsequent assignment of moderating duties to Khazret–his Director of R&D, according to LinkedIn. He even offered to join any new open community that might be formed. I will accept that at face value. If I were him, however, I’d have a chat with Kharzet about the costs of his actions. He is killing, or at least maiming, the Google group, and will taint Enomaly’s name.

  • I remain convinced that this could all be worked out easily by the community if an open conversation was allowed. Since that is not happening, I welcome others concerned about an open, fair exchange of ideas to follow me to greener pastures.

If you are a member of the group, and would like some of the facts in detail, please send me an email at jurquhart at yahoo dot com, and I’ll take the time to fill you in.

Here is where I will be hanging out:

  • Twitter, user ID “jamesurquhart

  • FriendFeed, user ID “jamesurquhart“, and the Cloud Computing room. This is the place I have the highest hopes for, as FriendFeed’s features combine streams with discussion to create a truly dynamic community, and the Room helps narrow the discussion to keep it on target.

  • Sam has a WIKI started at and I will likely be putting some of my more permanent content there for the community to hack (e.g. the Principles of a Cloud Oriented Architecture series)

  • One other intriguing option is Hug The Cloud (an unfortunate name), a Ning community that adds some excellent social networking features to the general discussion. Check it out, let me know what you think.

  • Update: I should also say, if anyone out there knows of a good alternative, open cloud computing forum, list, or network, please, please plug it in the comments below! I’ll only moderate off topic spam for this one post. 🙂

This is really a sad day for me. I wish cooler heads had prevailed. See you on the streams!

Cisco’s Nexus 1000v and the Cloud: Is it really a big deal?

September 17, 2008 Leave a comment

Yesterday, the big announcements at VMWorld 2008 were about Cloud OSes. Today, the big news seemed to be Maritz’s keynote (where he apparently laid out an amazing vision of what VMWare thinks they can achieve in the coming year), and the long rumored Cisco virtual switch.

The latter looks to be better than I had hoped for functionally, though perhaps a little more locked in to VMWare than I’d like. There is an explanation for the latter, however, so it may not be so bad…see below.

I’ve already explained why I love the Nexus concept so much. Today, Cisco and VMWare jointly announced the Nexus 1000v virtual machine access switch, a fully VI compatible software switch that…well, I’ll let Cisco’s data sheet explain it:

“The Cisco Nexus™ 1000V virtual machine access switch is an intelligent software switch implementation for VMware ESX environments. Running inside of the VMware ESX hypervisor, the Cisco Nexus 1000V supports Cisco® VN-Link server virtualization technology, providing

  • Policy-based virtual machine (VM) connectivity
  • Mobile VM security and network policy, and
  • Non-disruptive operational model for your server virtualization, and networking teams.

When server virtualization is deployed in the data center, virtual servers typically are not managed the same way as physical servers. Server virtualization is treated as a special deployment, leading to longer deployment time with a greater degree of coordination among server, network, storage, and security administrators. But with the Cisco Nexus 1000V you can have a consistent networking feature set and provisioning process all the way from the VM to the access, aggregation, and core switches. Your virtual servers can use the same network configuration, security policy, tools, and operational models as physical servers. Virtualization administrators can leverage predefined network policy that follows the nomadic VM and focus on virtual machine administration. This comprehensive set of capabilities helps you to deploy server virtualization faster and realize its benefits sooner.”

In other words, the 1000v is a completely equal player in a Cisco fabric, and can completely leverage all of the skill sets and policy management available in its other switches. Think “my sys admins can do what they do best, and my network admins can do what they do best”. Further more, it supports VN-Link, which allows VMWare systems running on Cisco fabric to VMotion without losing any network or security configuration. Read that last sentence again.

(I wrote some time about about network administrators facing the most change by this whole pooled-resource thing–this feature seals the deal. Those static network maps they used to hang on your wall, showing them exactly what system was connected to what switch port with what IP address are now almost entirely obsolete.)

I love that feature. I will love it even more if it functions in its entirety in the vCloud concept that VMWare is pitching, and all indications are that it will. So, to tell the story here as simply as possible:

  • You create a group of VMs for a distributed application in VConsole
  • You assign network security and policy via Cisco tools, using the same interface as on the physical switches
  • You configure VMWare to allow VMs for the application to get capacity from an external vendor–one of dozens supporting vCloud
  • When an unexpected peak hits, your VM cluster grabs additional capacity as required in the external cloud, without losing network policy and security configurations.

Cloud computing nirvana.

Now, there are some disappointments, as I hinted above. First, the switch is not stackable, as originally hoped, though the interconnectivity of VN-Link probably overrides that. (Is VN-Link just another way to “stack” switches? Networking is not my strong point.)

Update: In the comments below, Omar Sultan of Cisco notes that the switches are, in fact, “virtually stackable”, meaning they can be distributed across multiple physical systems, creating a single network domain for a cluster of machines. I understand that just enough to be dangerous, so I’ll stop there.”

More importantly, I was initially kind of ticked off that Cisco partnered so closely with VMWare without being careful to note that they would be releasing similar technologies with Citrix and Red Hat at a minimum. But, as I thought about it, Citrix hitched its wagon to 3TERA, and 3TERA owns every aspect of the logical infrastructure an application runs on. In AppLogic, you have to use their network representation, load balancers, and so on as a part of your application infrastructure definition, and 3TERA maps those to real resources as it sees fit. For network connections, it relies on a “Logical Connection Manager (LCM)“:

“The logical connection manager implements a key service that abstracts intercomponent communications. It enables AppLogic to define all interactions between components of an application in terms of point-to-point logical connections between virtual appliances. The interactions are controlled and tunneled across physical networks, allowing AppLogic to enforce interaction protocols, detect security breaches and migrate live TCP connections from one IP network to another transparently.”

(from the AppLogic Grid Operating System Technical Overview: System Services)

Thus, there is no concept of a virtual switch, per se, in AppLogic. A quick look at their site shows no other partners in the virtual networking or load balancing space (though Nirvanix is a virtual storage partner), so perhaps Cisco simply hasn’t been given the opportunity or the hooks to participate in the Xen/3TERA Cloud OS.

(If anyone at 3TERA would like to clarify, I would be extremely grateful. If Cisco should be partnering here, I would be happy to add some pressure to them to do so.)

As for Red Hat, I honestly don’t know anything about their VMM, so I can’t guess at why Cisco didn’t do anything there…although my gut tells me that I won’t be waiting long to hear about a partnership between those two.

This switch makes VMWare VMs equal players in the data center network, and that alone is going to disrupt a lot of traditional IT practices. While I was at Cassatt, I remember a colleague predicting that absolutely everything would run in a VM by the end of this decade. That still seems a little aggressive to me, but a lot less so than it did yesterday.

What the hell is going on with the Cloud Computing group on Google?

September 17, 2008 Leave a comment

Update: There is some counter evidence to Sam’s claim that he is the number 3 poster on the Google Groups Cloud Computing group, so I edited this post to reflect what is actually confirmed at this point.

Update 2: Sam points out below that he measured his ranking based on the last month, not all time. I’ll leave the text the way it is, as I can’t verify that (though I have no reason to doubt it), and the text is still accurate. If anyone in the group can verify Sam’s claim, I’ll change the text back and qualify it better.

One of the great resources for cloud computing fans and foes alike has been the Google Groups Cloud Computing online community. Started by Reuven Cohen at Enomaly in Toronto, and promoted by many of us participating in its discussions, it has quickly grown from 0 to over 3500 members. It is generally pretty active (though it ranks as “low activity” according to Google), but the sweet spot has been the frank and open discussions on threads that were incredibly informative and civil.

Normally one would praise moderation for keeping the riff raff out, but yesterday Sam Johnston told a story that has me very, very concerned. In the midst of a rant about the Enomalism as “vaporware” (which I won’t discuss here), Sam describes an exchange that, if true, indicates abuse and self-serving censorship of the kind that undermines the credibility of the group as an open forum.

Here is what Sam had to say:

It’s worth mentioning that I had good reason to do some background research. My recent post (cached copy) to one of the larger cloud computing Google Groups announcing Cloud User Shell (cush) (a free, open source prototype and the first cloud computing shell) made it through the invisible moderation net but information about its mailing lists was silently redacted and an off-list invitation for “Moderator ” (later found to be Khazret Sapenov, Director of R&D at Enomaly) to participate in the list management rudely rejected. When I requested that he “please add a few of the other active community members to [help] administer it” citing that “long blackouts are extremely disruptive” he childishly and silently evicted me from the group, deleted me from the member list, updated the FAQ to read ‘This group is moderated…at moderators personal discretion‘, and worst of all, silently and inexplicably deleted the announcement from the archives. Furthermore, in a stunning display of hubris they have hidden the member list even from members and infringed copyright by retrospectively relicensed the group posts under a Creative Commons license with neither notification nor permission!

Repeated requests to rejoin were denied and as the #3 poster at the time I reached out to Reuven, calling for “an unfettered communications channel which is open for anyone to join and post, and which is not dependent on (nor able to be held hostage by) any one person“. Reuven conceded that Khazret was his employee and that this “rather fascist approach to its moderation” was a “recurring theme“, adding that he “would love to have [me] involved in [his!?!] cloud book“. He promised to take care of it the following week (but didn’t) and repeated calls for them to open up the community have gone unanswered. Of course they claim this is an extracurricular activity but it’s hardly a basket weaving group, rather a massive conflict of interest directly related to their core [in]competency. Did this heated debate about the private cloud oxymoron really end here for example?”

Reuven and Khazret need the opportunity to respond, and I offer this post as a neutral venue to do so. Assuming they respond with a family friendly response, I will update this post to reflect it. Reuven took the initiative to found the group, as well as CloudCamp, and has an excellent blog, so I’d like to think this is all a big misunderstanding. I find it likely that Sam said something controversial about Enomalism or something, but unlikely that he did anything that justified being expelled.

I also think, however, that the Google Groups group needs to ask the Enomaly guys what their moderation policy is. The group’s home page says, “[M]oderation of comments is necessary to prevent spam, personal attacks, profanity, or off-topic commentary.” However, it is very hard to see how the Cust post could be seen as clearly falling in any of these categories. Is Reuven looking for independent moderators? If so, he should ask for them via a post in the group, and perhaps cite this controversy as a driving need for someone to step up. Out of 3500+ members, I am sure he would find two or three qualified people to help out.

In fact, perhaps moderation needs to move to a balanced team of, say, 3 people–no two of which work at the same company.

At the very least, transparency MUST be better than it has been in this case; having the number 3 poster a top 2% poster–one with that often forced you to think hard about your positions–cut without announcement or explanation is not acceptable. I, for one, am going to lose trust in the openness of the forum unless transparency and accountability improve.

Let the Cloud Computing OS wars begin!

September 15, 2008 Leave a comment

Today is a big day in the cloud computing world. VMWorld is turning out to be a core cloud industry conference, where many of the biggest announcements of the year are taking place. Take,for instance, the announcement that VMWare has created the vCloud initiative, an interesting looking program that aims to build a partner community around cloud computing with VMWare. (Thanks to the every increasingly cloud news leader, On-Demand Enterprise, for this link and most others in this post.) This is huge, in that it signals a commitment by VMWare to standardize cloud computing with VI3, and provide an ecosystem for anyone looking to build a public, private or hybrid cloud.

The biggest news, however, is the bevy of press releases signaling that three of the bigger names in virtualization are each delivering a “cloud OS” platform using their technology at the core. Here are the three announcements:

  • VMWare is announcing a comprehensive roadmap for a Virtual Datacenter Operating System (VDC-OS), consisting of technologies to allow enterprise data centers to virtualize and pool storage, network and servers to create a platform “where applications are automatically guaranteed the right quality of service at the lowest TCO by harnessing internal and external computing capacity.”

  • Citrix announces C3, “its strategy for cloud computing”, which appears to be a collection of products aimed at cloud providers and enterprises wishing to build their own clouds. Specific focus is on the virtualization platform, the deployment and management systems, orchestration, and–interestingly enough–wide area network (WAN) optimization. In the end, this looks very “Cloud OS”-like to me.

  • Virtual Iron and vmSight announce a partnership in which they plan to deliver “cloud infrastructure” to managed hosting providers and cloud providers. Included in this vision are Virtual Iron’s virtualization platform, virtualization management tools, and vmSight’s “end user experience assurance solution” technology to allow for “operating system independence, high-availability, resource optimization and power conservation, along with the ability to monitor and manage application performance and end user experience.” Again, sounds vaguely Cloud OS to me.

Three established vendors, three similar approaches to solving some real issues in the cloud, and three attacks on any entrenched interests in this space. All three focus on providing comprehensive management and infrastructure tools, including automated scaling and failover; and consistent execution to allow for image portability. The VMWare and Citrix announcements go further, however, in announcing technologies to support “cloudbursting” in which overflow processing needs in the data center are met by cloud providers on demand. VMWare specifically calls out OVF as the standard that enables this in their release; OVF is not mentioned by Citrix, but they have done significant work in this space as well.

Overall, VMWare has made the most comprehensive announcement, and have a lot of existing products to back up their feature list. However, much of what needs to be done to tightly integrate these products appears yet to be done. I base this on the fact that they highlight the need for a “comprehensive roadmap”–I could be wrong about this. They have also introduced a virtual distributed switch, which is a key component for migration between and within the cloud. Citrix doesn’t mention such a thing, but of course the rumor is that Cisco will quite likely provide that. Whether such a switch will enable migration across networks, as VMWare’s does (er, will?) is yet to be seen, however (see VMWare’s VDC-OS press release). Citrix does, however, have a decent stable of existing applications to support their current vision.

By the way, Sun is working feverishly on their own Cloud OS. No sign of Microsoft, yet…

The long and the short of it is that we have entered into a new era, in which data centers will no longer simply be collections of servers, but will actually be computing units in and of themselves–often made up of similar computing units (e.g. containers) in a sort of fractal arrangement. Virtualization is key to make this happen (though server virtualization itself is not technically absolutely necessary). So are powerful management tools, policy and workflow automation, data and compute load portability, and utility-type monitoring and metering systems.

I worry now about my alma mater, Cassatt, who has chosen to go it largely alone until today. Its a very mature, very applicable technology, that would form the basis of a hell of a cloud OS management platform. Here’s hoping there are some big announcements waiting in the wings, as the war begins to rage around them.

Update: No sooner do I express this concern, than Ken posts an excellent analysis of the VMWare announcement with Cassatt in mind. I think he misses the boat on the importance of OVF, but he is right that Cassatt has been doing this a lot longer than VMWare has.
