BSM with Oracle Enterprise Manager 11g

My colleagues Ashwin Karkala and Govinda Sambamurthy have written a book about modeling and managing business services using the current version of Enterprise Manager Grid Control (11g R1). Nobody would have been better qualified for this task since they built a lot of the features they describe. I acted as a technical reviewer for this book and very much enjoyed reading it in the process.

Whether you are a current EM user who wants to make sure you know and use the BSM features or someone just considering EM for that task, this is the book you want.

The full title is Oracle Enterprise Manager Grid Control 11g R1: Business Service Management.

As a bonus feature, and for a limited time only, if you purchase this book over the next 48 hours you get to follow the authors, @ashwinkarkala and @govindars on Twitter at no extra cost! A $2,000 value (at least).

Reading IBM’s proposed standard for Cloud Architecture

Did you enjoy the first version of IBM’s Cloud Computing Reference Architecture? Did you even get certified on it? Then rejoice, because there’s a new version. IBM  recently submitted the IBM Cloud Computing Reference Architecture 2.0 to The Open Group.

I’m a bit out of practice reading this kind of IBMese (let’s just say that The Open Group was the right place to submit it) but I would never let my readers down. So, even though these box-within-a-box-within-a-box diagrams (see section 2) give me flashbacks to the days of OGF and WSRF, I soldiered on.

I didn’t understand the goal of the document enough to give you a fair summary, but I can share some thoughts.

It starts by talking a lot about SOA. I initially thought this was to make the point that Glen Daniels articulated very well in this tweet:

Yup, correct SOA patterns (loose coupling, dyn refs, coarse interfaces…) are exactly what you need for cloud apps. You knew this.

But no. Rather than Glen’s astute remark, IBM’s point is one meta-level lower. It’s that “Cloud solutions are SOA solutions”. Which I have a harder time parsing. If you though “service” was overloaded before…

While some of the IBM authors are SOA experts, others apparently come from a Telco background so we get OSS/BSS analogies next.

By that point, I’ve learned that Cloud is like SOA except when it’s like Telco (but there’s probably another reference architecture somewhere that explains that Telco is SOA, so it all adds up).

One thing that chagrined me was that even though this document is very high-level it still manages to go down into implementatin technologies long enough to assert, wrongly, that virtualization is required for Cloud solutions. Another Cloud canard repeated here is the IaaS/PaaS/SaaS segmentation of the Cloud world, to which IBM adds a BPaaS (Business Process as a Service) layer for good measure (for my take on how Cloud relates to SOA, and how I dislike the IaaS/PaaS/SaaS pyramid, see this write-up of the presentation I gave at last year’s Cloud Connect, especially the 3rd picture).

It gets a lot better if you persevere to page 29, where the “Architecture Principles” finally get introduced (if had been asked to edit the paper, I would have only kept the last 6 pages). They are:

  1. Design for Cloud-scale Efficiencies: When realizing cloud characteristics such as elasticity, self-service access, and flexible sourcing, the cloud design is strictly oriented to high cloud scale efficiencies and short time-to-delivery/time-to-change. (“Efficiency Principle”)
  2. Support Lean Service Management: The Common Cloud Management Platform fosters lean and lightweight service management policies, processes, and technologies. (“Lightweightness Principle”)
  3. Identify and Leverage Commonalities: All commonalities are identified and leveraged in cloud service design. (“Economies-of-scale principle”)
  4. Define and Manage generically along the Lifecycle of Cloud Services: Be generic across I/P/S/BPaaS & provide ‘exploitation’ mechanism to support various cloud services using a shared, common management platform (“Genericity”).

Each principle gets a nickname, thanks to which IBM can refer to this list as the ELEG principles (Efficiency, Lightweightness, Economies-of-scale, Genericity). It also spells GLEE, but apparently that’s wasn’t the prefered sequence.

The first principle is hard to disagree with. The second also rings true, including its dings on ITIL (but the irony of IBM exhaulting “Lightweightness” is hard to ignore). The third and fourth principles (by that time I had lost too many brain cells to understand how they differ) really scared me. While I can understand the motivation, they elicited a vision of zombies in blue suits (presumably undead IBM Distinguish Engineers and Fellows) staggering towards me: “frameworks… we want frameworks…”.

There you go. If you want more information (and, more importantly, unbiased information) go read the Reference Architecture yourself. I am not involved in The Open Group, and I have no idea what it plans to do with it (and if it has received other submissions of the same type). Though I wouldn’t be surprised if I see, in 5 years, some panic sales rep asking an internal mailing list “The customer RPF asks for a mapping of our solution to the Open Group Cloud Reference Architecture and apparently IBM has 94 slides about it, what do I do? Has anyone heard about this Reference Architecture? This is urgent.”

Urgent things are long in the making.

A small step for SCA, a giant leap for BSM

In a very short post, Khanderao Kand describes how configuration properties for BPEL processes in Oracle SOA Suite 11G are attached to SCA components. Here is the example he provides:

<component name="myBPELServiecComponent">
  ...
  <property name="bpel.config.inMemoryOptimization">true</property>
</component>

It doesn’t look like much. But it’s an major step for application-driven IT management (and eventually BSM).

Take a SCA component. Follow the SCA-defined component-to-composite and service-to-reference relationships upwards and eventually you’ll get to top level application services that have a decent chance of mapping well to business-relevant activities (e.g. order processing). Which means that the metrics of these services (e.g. availability, response time) are likely to be meaningful and important to the line of business. Follow the same SCA relationships downward and you’ll end up (in a SCA-based infrastructure like Oracle SOA Suite 11G), with target components that are meaningful to the IT administrator. Which means that their metrics and configuration settings (like “inMemoryOptimization”) are tracked and controlled by IT. You now have a direct string of connections between this configuration setting and a business relevant metric. You can navigate the connection in both directions: downward/reactive (“my service just went down, what changed in the infrastructure”) versus upward/proactive (“my service is always slow, what can I do to optimize the execution”).

Of course these examples are over-simplistic (and the title of this post is a bit too lyrical, on account of this). Following these SCA relationships in brute-force fashion will yield tens of thousands of low-level configuration settings for any top-level service, with widely differing importance and impact (not to mention that they interact). You need rules to make sense of this. Plus, configuration-based models are a complement to runtime transaction discovery, not a replacement (unless your model of the application includes every single line of code). But it’s not that often that you can see a missing link snap into place that clearly.

What this shows is the emergence of a common set of entities between the developer’s model and the IT admin model. And if the application was developed correctly, some of the entities in the developer’s model correspond to entities in the mental model of the application user and the line of business manager. SCA is the skeleton for this. Attaching configuration to SCA components puts muscle on the bone.

The road to BSM is paved with small improvements in the semantic alignment between IT infrastructure and application services. A couple of years ago, I tried to explain why SCA is very relevant for IT management. Now we can see it.

Exploring “IT management in a changing IT world”

The tagline for this blog is “IT management in a changing IT world”. Of course nobody but their authors care about blog taglines. Still, in the unlikely event that I am asked to expand on the “changing IT world” part I would do it as follows.

The changes currently at work in the IT world can be organized along three axis:

  • IT infrastructure and management
  • Application development and delivery
  • Business and regulation

Each of these categories is ridiculously large. It’s only through the prism of the relationships between them that they provide any value. Think about three balls linked by coil springs.

If you give one of these balls a shake, you will start a hard-to-predict dance between them. This is similar to how the three domains above relate to one another. Changes in one (say a new focus on regulatory compliance in the “business” area, the emergence of virtualization technology in the “infrastructure” area or the appearance of Web 2.0 applications in the “application” area) start a complex movement involving all three. It takes a while to achieve a new equilibrium (and in practice it is never achieved since changes occur too often, adding stimulus to an already excited system). For a visual illustration, see this little YouTube video (but imagine that the three balls are arranged in a triangle rather than linearly and that every so often one of them gets pulled in a random direction).

This is not new of course. There have been changes in these three areas for as long as IT has existed (starting before it was called IT) and they have always driven changes in how IT is managed. To some extent they also have always influenced one another. The “new” part is that the connections are a lot tighter now, that the springs have a much higher force constant (the “k” in “F=-kx”). So here is my attempt at mapping today’s hot buzzwords on a map organized along these areas.

Before you ask: yes of course I have a very rigorous methodology, based on very precise quantitative data, to establish with certainty the exact x, y and z coordinates of each label. Buzzword topology is a precise science.

You may notice that the buzziest buzzword (at least currently), “Cloud”, does not appear on the map. It’s because it buzzes so much that it would be all over it, engulfing what currently appears as “virtualization”, “datacenter automation”, “Iaas”, “PaaS”, “SaaS” and “opex/capex”. There are two main parts in the “Cloud” buzzword: the “Technical Cloud” and the “Business Cloud”. The “Technical Cloud” is where we take virtualization and standardization (of machines, networks and application infrastructure) and turn that mind-boggling complexity into a manageable system that can be programmed to deliver applications (Cisco recently called it “Unified Computing”; HP, IBM and others have been trying to describe and brand it for a long time). Building on these technical capabilities comes the second part of “Cloud”, the “Business Cloud”. It is the ability to use infrastructure owned by a third party (presumably one able to leverage economies of scale) and all the possibilities this opens in the business realm. That’s what “Cloud” started as, back when it was known as “Utility Computing” and before it was applied to everything under the sun. A recent illustration of the relationship between the “Technical Cloud” and the “Business Cloud” is the introduction of vCloud by VMWare (their vision includes using VMotion technology, a piece of the “Technical Cloud”, not just to move machines between neighboring hypervisors but between organizations, enabling the “Business Cloud”). Anyway, that’s why “Cloud” it’s not on the map. It is actually all over it.

The system displayed on the map is vibrating very intensely right now, and I don’t see this changing anytime soon. Just for fun, here are candidates for future boxes on the map:

  • In the “IT infrastructure and management” category, maybe one day we’ll get to real metadata-driven management integration across the stack (as opposed to the more limited “application modeling” area listed above), whether through RDF or not.
  • In the “application development and delivery” category, maybe Doug Purdy’s vision “to make everyone a programmer (even if they don’t know it)” will be realized, whether through Oslo or not.
  • In the “business and regulation” category, maybe one day corporations will actually start caring about the customer data they are entrusted to (but only if mishandling it finally costs them more than “sorry about that, here is a one year credit monitoring subscription now go away”).

In summary, the evolution of IT management is driven not only by changes in IT technology but also by changes in two other fields (“application development and delivery” and “business and regulation”) with which it is tightly connected. Both of these fields are also in a very dynamic state. And they also influence one another, resulting in a complex three-way dance. You can’t understand the trajectory and moves of one dancer without seeing the others.

That’s what I mean by “IT management in a changing IT world”. Thanks for asking.

[UPDATED 2009/6/25: For more on the “technical cloud” versus “business cloud”, go read Neil Ward-Dutton’s nice explanation. He actually breaks down the “business cloud” in two (separating the economic aspect from the strategic aspect).]

Sorry, CMDBf doesn’t make coffee either

The IT Skeptic is writing to us from his mountain retreat (via a time-delayed post on his blog), and the topic he felt safe to cover in such fashion (what journalists call an “evergreen”) is the fact that CMDBf is an orchestrated sham, brilliantly executed by IT management vendors.

I’d love to be part of something that’s brilliantly executed for once, even if it is a sham, but I am afraid this is not it. But first I should state the obvious, clarifying that even though I am a member of the CMDBf group at DMTF (and also an author of the original version, under my previous employer) I do not speak for the group or DMTF (or my employer for that matter). Just as myself, as always on this blog.

The problem that Rob England, Mr. Skeptic, has with the CMDBf specification is that it doesn’t do a bunch of things that he’d like it to do, such as specifying how data sources acquire data for their domain, how they store the data, how the underlying resources are reconfigured, what processes are followed etc. See the full list from his post. The list is a copy/paste from the CMDBf specification, with some comments added, so at the very least he has to admit that as far as “smokescreens” go this one is pretty upfront about its limitations…

He concludes that “this is once again a geeky technical solution to a cultural, organizational and procedural problem.” I have to ask: who expects DMTF specifications to solve “cultural, organizational and procedural” problems? Does CIM solve such problems? Does WBEM?

Human-to-human communication is a “cultural, organizational and procedural” problem and SMTP/POP/IMAP/etc (the interoperable protocols used by email systems) are just as geeky as CMDBf. They don’t solve the larger problem, only contribute to the solution. If CMDBf can contribute as much to datacenter management as SMTP/POP/IMAP contribute to human communication (minus the SPAM if possible), I’d call that a success.

And then there is this warning:

“WARNING: vendors will waive this white paper around to overcome buyer resistance to a mixed-vendor solution. For example if you already have availability monitoring from one of them, one of the other vendors will try to sell you their service desk and use this paper as a promise that the two will play nicely.”

Has anyone actually seen this happen? I am asking because so far, both at HP and Oracle, the only sales reps I have ever met who know of CMDBf heard about it from their customers. When asked about it, the sales person (or solutions engineer) sends a email to some internal mailing list asking “customer asking about something called cmdbf, do we do that?” and that’s how I get in touch with them. Not the other way around.

Also, if the objective really was to trick customers into “mixed-vendor solutions” then I also don’t really understand why vendors would go through the effort of collaborating on such a scheme since it’s a zero-sum game between them at the end.

As far as the glacial pace of progress (“Glacial advance. That’s the way the vendors want it” from an earlier post by the Skeptic), CMDBf is no race horse but I don’t see it going any slower than other standards. Slowness (I mean, deliberation) is part of the landscape. I would submit a slight twist on Hanlon’s razor: “Never attribute to malice that which can be adequately explained by legal, procedural and organizational inertia.”

Having said all this, some of Rob’s criticism is perfectly justified, such as his sarcasm about this sentence from the specification:

“The Federated CMDB operates in a closed environment, in which some security issues are less critical than in open access or public systems.”

OK, that’s stupid indeed. Especially in a public cloud environment where you don’t know who is renting the VM next door. I’ll ask the group to remove this. Actually, that whole appendix is useless and I pointed this out in my earlier review of CMDBf 1.0 (look for the “security boilerplate” section at the bottom of the review).

Rob could also have pointed out that this specification only addresses “federation” if you accept a very scaled-down definition of the term. What it does do is help with CMDB query and synchronization. Not the holy grail, but nothing to sneer at either.

Rob, next time you want to throw tomatoes at CMDBf while you’re on holiday, just give me the password to the site and I’ll do it for you… :-)

[UPDATED 2009/1/21: Rob responds via a comment on his original blog entry.]

Forrester report on Oracle’s Enterprise Manager

Forrester’s Jean-Pierre Garbani wrote a short report last month about the current offering and future plans of Oracle’s IT management group (where I work).

As the report points out, Oracle’s IT management products don’t always enjoy a level of industry attention commensurate with the value they deliver. This report will hopefully help fix this.

Forrester: “Oracle Focuses On Business Value”.

Did someone at EDS miss the memo?

Two months ago, HP announced the acquisition of EDS.

One month later, HP Software announced a slew of new service management products, including an updated version (7.5) of Universal CMDB (from the Mercury acquisition).

One month later (today), according to BMC (with supporting quote from an EDS exec), “EDS Asia Pacific Standardises on BMC Software Atrium CMDB to Improve Service Delivery”.

As an ex-colleague pointed out to me, the acquisition isn’t closed yet. Still.

BMC acquires ITM Software

Another BMC acquisition today: ITM Software. Their software suite is designed to help drive IT decisions from the point of view of their business impact.

This is important, of course, for all the reasons that BMC, HP, Oracle and others have been explaining for a while (how often have you heard the word “alignment” over the last three years, compared to the previous thirty?). It’s becoming even more important now, as the options for IT sourcing (from the traditional “give it all to Unisys”, to SaaS, to running your own apps in a utility computing environment…) are multiplicating. Choosing between Intel and AMD CPUs in your datacenter is a technical decision, but choosing between an on-premise application, a SaaS application and running your application on EC2 is driven by business considerations of cost, risks, control, flexibility, etc. And it’s not just a one-time decision, it’s the day to day management that follows these decisions.

I don’t know much about the current ITM offering, but it was never clear to me how much they could deliver as a narrow layer, separate from the heavy-duty IT management stack (I can see how they would deliver financial and project management tools, but what about *really* linking day to day IT administration decisions to the business impact). Being part of BMC, presumably allowing deeper integration into real IT management operations, seems to make sense.

I just wish they didn’t make it sound so easy: “BMC’s purchase of ITM Software creates a unique, integrated solution that provides customers with a single comprehensive view into…”. So just signing the check creates the integration? Now I am going to get calls from our execs asking why it takes so much work to integrate acquired products, if BMC can do it the same day they sign the deal…

While I am at it, here is the press release that HP put out to list the announcements at their Software Universe conference this week. I notice that it’s all about new versions of ex-Mercury products. No OpenView, Peregrine or Opsware content, as far as I can tell. Without looking at it in more details I don’t know how different these new versions really are. What appears pretty new is the SaaS offering (also based on Mercury products) at the end of the press release. On the nitpicking side, can anyone tell me what these “static configuration management databases” are that are “unable to support the real-time needs of today’s complex technology environments”? I can see how a “static” database would be hard-pressed to help, but I haven’t noticed any vendor selling read-only config stores.

[UPDATED 2008/6/18: More details about the HP announcement at InfoWorld. Including quotes from my ex-boss Ramin. Congrats on getting UCMDB 7.5 out of the door!]

DevCampTivoli

Our esteemed competitors at IBM Tivoli are organizing a BarCamp focused on the use of ITM for BSM. Should be very interesting if they manage to convince a good group that this is a valuable way to spend a weekend. BSM on Tivoli seems like an ambitious topic for a “getting your hands dirty” kind of session since by definition BSM involves managing complex systems and solving the needs of the kind of people who don’t necessarily attend BarCamps. Very different from the more typical BarCamp environment in which people bring code (typically open source) they know in and out and try to get these projects to do things that they themselves plan to make use of.

Just setting up a realistic (even if fake) environment to get your “hands dirty” on can take a lot of time. Long downloads and complex installation procedures aren’t your friends when you only have a few hours (and when participants don’t have to stay in the room if they’re bored). It will be an interesting challenge for the organizers to decide how much (if anything at all) to prepare ahead of time while keeping the whole thing open and participant-driven.

My guess is that even if they don’t get a lot in terms of BSM insight per se, they will learn a lot about the ease of installation, integration and extension of the various products involved and how to increase it, which will be beneficial all the same. Good luck to Doug, John and the other participants, I think you’ll do well and I hope you’ll achieve even more than I predict. Kudos for the initiative.

Of course the real challenge only starts after the BarCamp: it is to take the lessons back to the mothership…

And for those who say I only speak critically of IBM on this blog, this post is the proof that you are as prejudiced as a WebSphere architect. ;-)

[UPDATED on 2008/01/17: Make sure to read John’s clarifications in the comments section, including the link to BarCampESM which is happening this coming weekend in Austin. I hadn’t heard about it before.]
