OVF 1.0 just got released as a DMTF standard. Here is the specification and its companion white paper. After a quick scan I didn’t see any major change from the submitted version, which is consistent with the content of the “preliminary standard” from last year.

The interesting question is what comes next, especially with regards to VMWare’s vCloud. The VMWare press release stated that “as one of the original authors of the Open Virtualization Format (OVF) standard now released from the Distributed Management Task Force (DMTF), VMware will build upon that work by submitting a draft of its VMware vCloud API to enable consistent mobility, provisioning, management, and service assurance of applications running in internal and external clouds” and Drue Reeves at the Burton group commented on this (Drue, we’re still waiting for part II). I see no reason to believe that VMWare is going to stop playing by the Microsoft playbook in DMTF as it appears to be quite successful so far (I’ll pat myself in the back for predicting over a year ago that “OVF might only be the beginning” for VMWare at DMTF).

This results in what looks like a landgrab from DMTF in Cloud standards. Meanwhile, in Washington DC yesterday, the Strategies and Technologies for Cloud Computing Interoperability (SATCCI) workshop took place. At this point all I know about it is the report from Reuven Cohen that I just read (hopefully Stu, Krishna and other bloggers who participated will provide additional perspectives). From Reuven’s report, Winston Bumpus (Director of Standards Architecture at VMware and President of the DMTF) described OVF as “an ideal cloud migration and deployment package”. Which may be true but is a pretty recent repurposing (the spec and the white paper don’t even mention this application). And while the DMTF is going full speed ahead on this, Reuven reports that “Craig Lee, President of the Open Grid Forum suggested that we need to take more time to examine the overlap between various standards groups, mapping the opportunities for collaboration”. Sure thing. The old timers might remember that when the DMTF decides to run with Microsoft’s WS-Management it wasn’t just OASIS (where WSDM was created) that eventually got hosed but also OGF (then called GGF) which relied on the WSRF/WSDM stack. At the time too there were discussions to identify and reconcile the overlap, for all the good they did (disclosure: I have some history there).

We’ve seen this in the WS-* game before. At the end it’s not so much a matter of what the standards bodies do (and even less of what they say), it’s a matter of what the big players do and where they choose to take their marbles. To the extent that you can separate the two, which becomes tricky in the case of vendor-run bodies like WS-I and DMTF. As I have written before, “at the end, it comes down to what [you think] a standard should be”.

[UPDATED 2009/3/26: Stu has now written a report on the SATCCI meeting.]

This is an exciting time for those who want to shrink the computer. They are having a field day playing with devices powered by Android, the iPhone’s Cocoa, Palm’s new WebOS, Windows Mobile, JavaFX (maybe one day) and, to a lesser extent, the Blackberry.

But times are good too for those who want to go the other way and program larger things rather than smaller ones. If you are interested in thinking about datacenters as a programmable entity, you are in luck: for these long plane trips when you run out of battery, bring a printout of the proceedings of the research meeting organized last year in Cambridge by Microsoft and HP Labs, titled “The Rise and Rise of the Declarative Datacentre”. When you’re back on-line go check the presentations on the site.

And if you liked Paul Anderson’s “Programming the Data Centre” presentation at the Cambridge meeting, you can also read his “Programming the Virtual Infrastructure” slides from LISA 08. More LISA 08 presentations here.

I got the link to Paul Anderson’s second presentation (and maybe also the first one, some time ago) from Steve Loughran, who also adds a few comments, starting with the debate between the declarative and procedural approaches. This question has plenty of down-the-road implications. There is a lot to like about the declarative approach in terms of composition, manageability and more generally as a framework to manage complexity via encapsulation.

A simple analogy for this debate is to think about driving directions. The declarative approach is for me to give you a map with a circle on it showing where my house is and let you find your way. It’s more work for you but it’s also more resilient. The procedural approach is for me to give you a set of turn-by-turn directions, based on where you are coming from. If you miss one turn or if one road happens to be blocked at the time, then you’re in trouble.

That being said, there are enough powerful and useful PowerShell or Puppet scripts out there to give you a pause before discarding procedural approaches. While the declarative (aka “desired state”, “policy-driven” and sometimes “model-based”) approach looks a lot more elegant, at this point in time the real work usually gets done via scripts, deployment procedures or the likes.

In additin to academia, the competition between these approaches is playing out right now between all the companies and products that want to help you automate and manage your cloud deployments (public and/or private): for example, Rightscale scripts (custom scripts and Righscripts, see here and here) versus the more declarative ECML/EDML documents from Elastra. Or the very declarative approach taken by SmartFrog.

If you’ve seen a lot of news articles about HP’s IT management software this week (e.g. through Cote or Doug) it’s because the company held its Software Universe conference in Vienna this week and timed a bunch of announcements and PR events to match.

Most of the articles linked above just paraphrase the press releases and talking points. So if you’re going to get the company line, might as well get it straight from the horse’s mouth. Which we can now do through a new HP blog about BSM. The first article was penned by Mike Shaw and that’s enough for me to want to subscribe (I worked with Mike a few times when I was at HP and he is very sharp). I think Mike also wrote the other entries but since they are not signed (and the account name, “adsey007″, is pretty opaque) I am not sure. In any case, they are pretty good. This one gives an overview of the Vienna announcements. The next one describes in more details the OMi product. I am not in position to know how well it works but, according to the article, OMi takes the important step of modeling and managing events in the context of the overall model in the CMDB. Such that the event management features (e.g. correlation) can use the already-discovered relationships between the IT elements involved in the events (e.g. dependencies). The article also implies that the CMDB has been integrated with NNM (OpenView), Service Manager (Peregrine) and Server Automation (Opsware). Which is a lot of progress in 16 months since I left HP, so I am taking it with a grain of salt (we all know there are different levels of integration). The press release says that the CMDB is now integrated with 17 HP BTO applications, so you may need a whole salt shaker. In any case it’s great to see that Ramin and team are forging ahead, delivering products and driving the integration of the BTO portfolio.

The last paragraph (“OMi actually sits on top of existing HP Operations Manager installations…”) is intriguing and may provide a clue about the depth of the integration. In any case, OMi is something to keep an eye on as it is positioned to leverage a lot of the key strengths of the HP BTO portfolio.

BTW, this OMi product has nothing to do with this OMI which was a precursor to WSMF, WSDM and WS-Management. And which most people currently working in HP Software have never heard of.

Many of us have been thinking (a bit) and talking (a lot) about the relationship between Clouds and good old IT management.  John understands both sides and produced a few good posts (like this one).

Maybe it’s just a coincidence that both Hyperic and CA recently made such announcements. In any case, it gives the impression that time has come for some actual product capabilities in the area of managing Cloud-based systems.

I haven’t investigated either, so keep your slideware shields up, but this is what I read:

From Javier Soltero’s “Announcing HQ 4.0″: “It also provides the first cloud-friendly management agent which allows users to manage cloud based virtual machines securely and reliably from either inside the cloud, or from HQ 4.0 installations inside your datacenter”. John approves.

And at CA World, according to InformationWeek, “CA will announce a partnership with Amazon to provide management capabilities around Amazon’s EC2 utility computing platform, potentially including discovery of software running on EC2 instances, performance monitoring, configuration management, software deployment capabilities and provisioning”.

When someone looks into these two products (and others, soon to follow or alrady out and that I have missed), it will be interesting to see how these Cloud-friendly capabilities relate to the good old capabilities of management products: “software discovery”, “perf monitoring”, “config management”, “software deployment”, “provisioning”. That all sounds pretty familiar. Is it just a matter of pointing the old tools to an EC2 IP address? Is it all new capabilities, done in a new way? Or, more realistically, where does it land between these extrems? Where do you want them to land? It’s not so obvious.

Utility computing comes with an expectation of additional flexibility (now that is obvious). When tweaking IT management tools to address the domain, does one leave “in datacenter” capabilities the same and branch off to do cool things in the new land? Or do you raise the level of flexibility accross the board?

In other words, rather than snickering at them, maybe we should praise IT management vendors for whom the “look, I do Clouds” marketing spiel is just a repackaging of normal IT management features. Because it may mean that they’ve raised the bar on “in datacenter” automation capabilities. These Opsware and BladeLogic acquisitions have to come in somewhere, don’t they?

BTW, both of the announcements above also perpetuate the confusion between providing utility services (CA’s extended SaaS offering, Hyperic’s release of a pre-packaged Hyperic AMI) and the ability to manage Cloud-based systems. It’s all crammed in the same announcement/article because, hey, it’s all Cloud stuff.

Speaking of CA World, if I was there I would go to this session. At least for old time sake, and maybe to get some interesting ideas. Hopefully Don will blog about it after he is done presenting later today.

IBM’s well-publicized new policy for technology standards is an interesting development. The first image it conjured for cynical me is that of an aging Heavy Metal singer ranting against the rudeness of rap lyrics.

Like Charles, I don’t see IBM as an angel in this domain and yet I too think this is a commendable move on their part. Who better to stop a burglar than a (presumably) reformed burglar anyway? I hope this effort will succeed and I am glad to see that my colleague Jim Melton was involved in the discussion facilitated by IBM and that Trond supports it too.

My experience in standards (mostly from back in my HP days) only covers a small portion of IBM’s technology standards involvement of course. But in all instances, both IBM and Microsoft were key players (either through their participation or through their glaring refusal to participate). And within that sample (which does not include OOXML) my impression is that IBM did indeed play more cleanly than Microsoft.

They also mostly lost, while Microsoft mostly won. Whether there is a causality here is possible but not proven. IBM seems to have an ability to loose by winning: because they assign so many people to standards they wear out everybody else and at the end, they get the final document to be the way they want it (through the normal process, just by being relentless). But the specification is by then so over-engineered, so IBM-like in its approach and so late that it’s usually a Pyrrhic victory. Everybody else has moved on and IBM has on their hand something that’s a standard on paper but that only players in the IBM ecosystem implement. Pushing IBM’s CBE event format in WSDM, over-complicating aspects of WSRF like WS-ServiceGroup and butchering the use of SOAP headers in WS-ResourceTransfer to play nice with WebSphere are, in my mind, such examples. They can’t blame Microsoft for those.

Also, nobody forced them to tango with the devil in that whole WS-* saga. What they are saying now is similar in many ways to what Oracle was saying (about openness and fairness) throughout this decennia while Microsoft and IBM were privately defining machine to machine interoperability protocols for the enterprise. And they can’t blame standards for the way Microsoft eventually took advantage of them there, because they *chose* to do this outside of standards. I wish I had been a fly on the whole when this conversation took place:

IBM: We’re going to need a neutral DNS name for all these new XML namespaces. It wouldn’t be right to do it under ibm.com or microsoft.com.
Microsoft: You’re right. Hey, I just registered xmlsoap.org last week with the intent to launch a B2B forum for the detergent industry, but if you want we can use it for our Web services specs.
IBM: Man, that’s perfect. Let me give you twenty bucks to help pay the registration.
Microsoft: No, really, no big deal. It’s on me.
IBM: You’re too cool man.

But here I am, IBM-bashing again while the point of this post is to salute and support their attempt at reform. Bad, bad William.

OK, so now for some (hopefully) constructive remarks and suggestions.

I think commentaries and reports on the news have focused too much on the OOXML/ISO story. Sure it’s probably a big part of the motivation. But how much leverage does IBM really have on ISO? Technology standards is just a portion of what ISO does. And it’s not like ISO has much competition anyway, with its de jure international standing. Organizations like the JCP, DMTF and W3C have a lot more too lose if IBM really gets mad at them.

I think it’s clear that Microsoft is the target, but if ISO reform was the main prize, I don’t think IBM would go at it that way. ISO will only change in response to government pressure. If government influence is a necessary step, isn’t it cheaper and more direct for IBM to hire a couple more lobbyists than to try to rally the blogosphere? I think they really want to impact all standards setting organizations at the same time. If ISO happens to be one of those improved in the process, that’s gravy.

IBM calls its report “standards for standards” (at least that’s the file name). I think (and hope) the double entendre is voluntary. It’s not just a matter a raising the (moral and operational) standards of standards organizations. It should also be an occasion to standardize how they work, to make them more similar to one another.

Follow me for a second here. One of the main problems with many organizations is their opacity. They have boards, task forces, strategic committees, etc. Membership in the organization is stratified, based mostly on how much you are willing to pay. I would guess that most organizations couldn’t make ends meet if all member companies paid the “base membership” fee. They need a dozen companies to pay the “leadership” fee to fund their operations. For these companies to agree to the higher price of participation, they need something in return. They need to have more access than the others. Therefore, some level of access must be denied to the base members (and even more to the non-members, which is why many such organizations make almost no information publicly available).

They are not opaque by accident, they are opaque by design because they need to be in order to be funded. There are two ways to fix this. One is to have fewer organizations, such that the fixed costs of running an organization can be more widely spread. But technology is very specialized and there is value in having organizations that are focused and populated by domain experts. The other way is to drastically reduce the cost of running a standards organization. That’s where standardization of standards organizations comes in. If the development processes, IP policies, bylaws and tools were commonly shared among standards organizations, it would be a lot cheaper to run one.

Today, I can start a new open source project for free on Sourceforge. I can pick one of the clearly-identified open source licenses that have been pre-defined. I can use the usual source control, collaboration and bug reporting tools. Not only is it almost free, my users will know right away how to participate. Why isnt’ it the same for standards organizations? Or only so partially. I know that Kavi is used by many standards organizations. I’ve used their tool both as a DMTF participant and an OASIS participant. And it doesn’t really fit either perfectly because the processes are slightly different. Ballots are conducted differently, attendance rules are different, document visibility rules are different, roles are different, etc.

It sounds superficial, but I am convinced that a more standardized approach to IP policies, organization bylaws and specification development processes would result in big savings that would open the door to much more transparency.

Oh yeah, you’d also have to drop the boondoggle plenary sessions in resorts all over the world. Painful, I know.

Sure there are other costs, such as marketing costs. But fully transparent organizations, by making their products more easily accessible to users, have a much lower need to use traditional marketing to get the word out. In the same way that open source software companies get most of their marketing via their user community. Consistency among standards organizations would also make it a lot easier for small companies to participate since anyone who’s learned the rules once can be effective right away in a new organization.

I want to end with a note of caution directed at IBM. You have responsibilities. I hope you realize that at this point, approximately 20% of all airplane seats are occupied by IBM employees going to or coming back from some standards-related meeting. The airlines are hurting already, you can’t pull out at once. And who will drive all these rental Chevys? Who will eat all the bad sushi in airport food courts and Benihana restaurants?

[UPDATED 2008/10/20: From Tim Bray, another example of IBM loosing by winning in standards: "Unfortunately, that spec [XML 1.1] came with excess baggage, namely changed rules on what constitutes white-space, rammed through by IBM for the convenience of their mainframe customers. In any case, XML 1.1 has been widely ignored”.]

The announcement finally came out. Users can now run supported versions of Oracle Enterprise Linux, 11G Database, Fusion Middleware and Enterprise Manager on Amazon EC2 instances. You can create your own AMI or use any of the pre-packaged AMIs with the above-mentioned products. And you don’t have to purchase new licenses, you can transfer existing ones to run on Amazon’s infrastructure.

A separate but related announcement is the possibility to simply and securely backup your databases on Amazon S3 instead of (or in addition to) on tape. I hope BNY Mellon will take notice.

The Amazon AWS blog has a good overview of the news. Forrester covers it with a focus on data warehousing.

This comes in addition to the existing SaaS offering (“On Demand”) from Oracle and the SaaS platform (for others to provide SaaS on top of Oracle’s software). It is a major milestone for utility computing.

To that end, we’ll need you to RSVP and to prepare a 5-10 minutes presentation about your application management challenges.

Here is the agenda:

• Introduction
• Customer Presentations on Application Management
• Oracle’s Approach to Application Management
  • Real User Monitoring (Moniforce)

BTW, I’ll be at OOW next week (probably Wednesday and Thursday) so if you plan to be there and would like to meet let me know.

There is more and more information coming out about Oslo in anticipation of the Microsoft PDC in October.

David Chappell recorded a video about it last month. More recently Doug Purdy and Don Box each posted a short description of Oslo. Don describes the goal of Oslo as “simplify the process of developing, deploying, and managing software”. But when he lists ancestor technologies to illustrate that “Microsoft has been moving in this direction for over a decade now”, they are all about development, not management: COM type libraries, .NET metadata attributes, XAML. Interesting that neither SDM nor SML gets a mention. Neither did SCA by the way, but I wasn’t really expecting that one… :-)

Maybe the I am the only one looking for a SDM/SML echo here, just because I came to hear of Oslo through the DSI angle. Am I wrong to see Oslo as an enabler for DSI? This eWeek article doesn’t have anything to do with IT management. Reading it, Oslo is all about allowing people to write code through drag and drop. Yawn. And Don Box endorses the article.

Maybe it’s just me (an IT management guy more than a software development guy) but I don’t care so much about how the application model is created. I care a lot more about what it allows you to do in terms of IT management. Please don’t make me pull out the often-quoted figure about the percentage of IT budget spent on operations versus development/licensing. The eWeek piece fails to excite me, but fortunately David Chappell’s video interview is a lot more aligned with my thinking, so I still hold hopes for Oslo as an IT management enabler. Here is my approximate transcript of an example that David provides (at around 4:20) in the video:

“If someone comes to you and says i’ve got this business process and the SLA is not being met, what do you do? You’ve got to trace this through the right business process and the right application that supports that part of the process and find the machine it runs on and maybe look at the workflow that implements it and maybe look at the services that it provides. This involves talking to business analysts, or the IT pros or the architect or the developer, all of whom have their own view of the world, their own tools, their own prospective. The repository provides a common place to store all this stuff, to link it all together, and with a visual editor to have a common tool that lets you actually go through and answer this kind of questions.”

Now you’re talking.

And if Oslo is not the new blood of DSI, then what is? The DSI story is getting dated, SML is fading in our memories and of the three parts that supposedly compose DSI (“virtualized infrastructure, design for operations, and knowledge-driven management”), only virtualization is actually represented on the list of technologies on the DSI home page. Has DSI turned into just allowing System Center to manage a hypervisor? I still hold hopes that the Oslo data is going to spice things up there. It would be good for the industry at large, not just Microsoft.

I won’t be at the PDC but it will be interesting to see what filters out of these sessions. The first session in the list adds management of hybrid application systems (hybrid as in “cloud/on-premise combination” or “software+services” as Microsoft calls it), to the long “can do” list for Oslo. Impressive, if there is some meat behind the abstract. I think this task is often overlooked in discussions around management aspects of Cloud computing (see “the new, interesting thing is going to be the IT infrastructure to manage your usage of utility computing services as well as their interactions with your in-house software” in this previous entry).

Yes, I am reading way too much into session abstracts, but while I am at it I can’t help noticing that there is a lot of SQL and very little XML/XSD/XPath mentioned there. Even though one of the presenters is Gudge, the only person I have ever met who fully understands XSD (actually even he doesn’t, I’ve seen him in the WS-I days have to refer to… his book).

Even though I am sure we’ll be told that SML can be built on top of Oslo, the SQL orientation won’t make that so easy (I want to see how to build XSD+Schematron validation on top of a relational store using Oslo’s drag and drop development tool). And it puts Microsoft on a different architectural direction from IBM, who, as far as I can tell, thinks that the world is a big XML document. Neither is the most appropriate for IT management models. I prefer a graph model and associated graph queries along the lines of SPARQL or CMDBf.

But that’s just late-night idle speculations on my part (aka “blogging”). Let’s see what comes out in October.

[UPDATED 2008/9/10: Interesting timing. Microsoft is joining OMG, home of UML and BPMN. Coming next: a submission of a "new version" of UML and BPMN that happens to contain the extensions and tweaks that Microsoft made to them in the process of implementing Oslo. This, BTW, is the final nail in the SML coffin (SML isn't even mentioned in the press release).]

IBM and CA are apparently showing an interoperability demo between their respective CMDBs at itSMF Fusion this week. I am not there to see it, but they describe it (it’s a corporate merger scenario) in this press release. It is presumably based on the version of the specification that was submitted to DMTF.

More information about CMDBf, along with another demonstration, will be available in a couple of months for ManDevCon attendees. Three sessions are on the agenda, all in a row and in the same room (so make sure to get a good seat, i.e. one close to a power plug, from the start):

• CMDB Federation Overview (Vince Kowalski, BMC and Marv Waschke, CA)
• CMDB Federation Technical Description (Mark Johnson, IBM and Marv Waschke, CA)
• CMDB Federation Demonstration (Mark Johnson, IBM and Dave Snelling, Fujitsu)

I just found out that I completly missed some interesting information about Oslo-related efforts at Microsoft. Back in February, Mary-Jo Foley reported on a new modeling language (code-name “D”, apparently) that is part of this initiative. And more recently she reported that David Chappell gave a presentation about Oslo (and more generally Microsoft’s SOA plans) at TechEd. He reportedly said that we should expect a new “schema language” (which Mary-Jo thinks is “D”). What I want to know is what its relationship is with SML/SDM and SCA.

Mary-Jo might not know about SCA and SML but I know that David does. He wrote this white paper about SCA and an article arguing that “Microsoft Should Not Support SCA” (based on an a questionable assessment that SCA is only about portability). He and I also had a little back-and-forth about SCA, SML and Microsoft in the comments section of his post. Unfortunately, David hasn’t blogged about Microsoft’s SOA strategy for a while for us non-TechEd people.

In addition to Mary-Jo’s report, the only information I was about to quickly dig out about David’s presentation is this blog post on Microsoft’s Israel site. Looks like David gave the same presentation at TechEd Israel 2008. Anyone who understands Hebrew cares to translate the blog? Fortunately there is a two-minutes video (also available here) in which we can hear David talk (in English). During the second of the two minutes you’ll hear and see something that could come straight out of a SCA presentation…

For some reason, David’s TechEd Israel presentation doesn’t seem to be listed here and TechEd online tells me that “Featured videos are unavailable at this time”. That’s both for IT Professionals and Developers. But of course they forced me to install Silverlight before telling me that.

[UPDATED 2008/8/11: Here is a 14 minutes video interview of David Chappell providing an update on Oslo.]
