DSI, OSLO and Models in the Lifecycle. Get Prepared..!

OSLO vs DSI vNext.
There is lot of buzz around Oslo and it looks like all the ideas around this concept are completely new. But when you take a look at the vision behind Oslo it's not that new, it's acutely the next step to maturity of Microsoft's Dynamic Systems Imitative [DSI] from a few years ago.

What is OSLO?
From http://www.microsoft.com/soa/products/oslo.aspx...

Making a new class of model-driven and service-enabled applications mainstream.
Deliver a world class and mainstream modeling platform that helps the roles of IT collaborate and enables better integration between IT and the business. The modeling platform enables higher level descriptions, so called declarative descriptions, of the application.

Ron Jacobs talks about Oslo in this video...
models
[always interesting to listen to Ron Jacobs but from minute 14 it gets interesting]

Key points of Oslo are:

  • Models (Making models a mainstream part)
  • Services (Extending services from the client to the cloud -- S+S).
  • Integration (Limit the boundaries between Business and IT and within IT departments)

An important part of the vision is that the models exist in the whole lifecycle. So, they not only exist during analyses and design.

Another idea is that all the different models are connected. So, all the different viewpoints [operations, security, application, environment, etc] stay in sync. enable integration. "Enable ALM by Automation" [I talked about this in some previous posts]

Beside this application lifecycle management support with models, there is a focus on S+S application types. Products launched with this concept in mind are also counted under the Oslo umbrella and should also support this modeling vision. For example Biztalk Services [ a must visit link Biztalk Labs ] and the Internet Service Bus.

What is DSI?

DSI is a vision from around 2003, ages ago... smile_teeth

 

Microsoft has established the Dynamic Systems Initiative (DSI) to build software solutions that facilitate the movement to the Dynamic stage. DSI describes a vision where IT systems become self-aware and self-managing. From a core technology perspective, DSI is about building software that enables knowledge of an IT system to be created, modified, transferred, and operated on throughout the life cycle of that system. These core principles—knowledge, models, and life cycle—are the keys in addressing the complexity and manageability challenges that IT organizations face today.

DSI

Key points of DSI are:

  • Knowledge,
    building software that enables knowledge of an IT system to be created, modified, transferred, and operated on throughout the life cycle of that system.
  • Models,
    System Definition Model (SDM) provides a common language, or meta-model, that is used to create models that capture the organizational knowledge relevant to entire distributed systems.
  • Life cycle
    Business, Development and Operations by providing integration between the various tools used and activities performed within each of these capabilities.

What do have OSLO and DSI in common?

    Models in the Lifecycle..!

The Products... [DSI]
Visual Studio 2005 Team Edition for Architects was the first product with designers/ models. The VSTA designers [application diagram, logical datacenter diagram, deployment diagram] where the first implementation of DSL's [Domain Specific Languages] with SDM as language.

The Dynamic Systems Initiative (DSI) is a commitment from Microsoft and its partners to help IT teams capture and use knowledge to design more manageable systems and automate ongoing operations, resulting in reduced costs and more time to proactively focus on what is most important to the organization. The System Definition Model (SDM) is a key technology component of the DSI product roadmap that provides a common language, or meta-model, that is used to create models that capture the organizational knowledge relevant to entire distributed systems.

Quote from System Definition Model Overview White Paper.

SMS and MOM are the other products which supported SDM. SDM later evolved to SML [SML Insight blog].

The model-based management functionality in Windows Server 2008 is based on Microsoft's System Definition Model (SDM) version3, which provided the basis for the Service Modeling Language (SML) proposal and submission to the World-Wide Web Consortium SML Working Group.

SCCM2007 SCOM2007 and Windows Server 2008 are also based on SML.image
And there are a lot more products with models in it now days, all of them stand alone. During the past Orcas TAP program I worked on some ideas to connect those models. 

The products... [Oslo]
Visual Studio "10" is one of the products that's going to support the Oslo vision [see image from Ron Jacobs video].
What can we see in the recent released Rosario April CTP about this? Not much... although, we can see a shift in focus in the architecture edition [more models] and we can see an investments in the modeling tools [designer bus]. We have to wait for other releases to get more implementation details... a visit to Biztalk Labs is interesting to get some ideas around the "Cloud"Services [Identity Services, Connectivity Services and The BizTalk Labs SDK].

Prepare for Oslo.
Not much news around "Oslo"products, but this doesn't have to mean that we have to sit down and wait. The mind-switch, the internal culture are more challenging then the adoption of new development products.

First, developers, operational managers, the business and everybody else involved in software development must starting work together, for example developers and testers [Collaboration between Test and Dev.: Rob Kuijt talks about this, Collaboration between dev. security manager and architects: Creating Secure Services, with Visual Studio Team Architect and the Web Service Software Factory and operational manager]. Seems like an open-door but more challenging then it looks like, because it's mostly the internal culture how people collaborate. This collaboration should first be supported by processes, within Oslo its going to be supported by models.

Second, start working with models there are already a bunch of models available. The mind-switch it takes is big. Architects can start working with Team Architect, developers with the Web Service Software Factory Modeling Edition and other, analysts with CTP 12 UML diagrams, operational managers with SCOM etc etc etc... get experiences. Give some control away to the models...

Third, start take a look at Software + Services / SaaS. Take services from The Cloud go look what you need. For example SLA's are interesting and what kind of capabilities do you need from those cloud services? [ Software plus Services [S+S] vs Software as a Services [SaaS] The Battle ]

Anyway, its an interesting time...
