SOA, Cloud, and Semantic Web Technology talk

Earlier this month a talk by Thomas Erl (bestseller author on SOA and Cloud Computing) on SOA, Cloud Computing and Semantic Web technologies became available on the Arcitura Youtube channel. This talk gives a less than 30 minutes overview in how these work together. It has a focus on highlight promissing areas of synergy.

The definition used for Cloud Computing is:

Cloud computing is a specialized form of distributed computing that introduces utilization models for remotely provisioning scalable and measured IT resources.

The definition used for Semantic Web Technologies is:

Semantic Web Technologies represents a technology platform used to describe artifacts, their properties, and their relationships using machine-processable language.

SOA Symposium 2010 videos available via InfoQ

This year, in partnership with InfoQ.com (the largest community site for technical architects), 1/4th of the SOA Symposium sessions was filmed and will be published on InfoQ. From early November InfoQ has started publishing these videos. At the time of writing the following videos are available:

Cloudy SOA

This session on Cloudy SOA by Mark Little covers:

an introduction to cloud computing pointing to the fact that the middleware needs of the cloud are similar to SOA’s, showing some of the benefits of running SOA along with the cloud, asking if cloud computing and SOA should evolve together and giving some future directions to consider.

BPM Top Seven Architectural Topics in 2010

Hanjo Normann’s session presenting the BPM Top Seven Architectural Topics in 2010 covers:

how to design a BPM/SOA solution including: modeling human interaction, improving BPM models, orchestrating composed services, central task management, new approaches for business-IT alignment, solutions for non-deterministic processes, and choreography.

Resurrecting SOA

Anne Thomas Manes in her Resurrecting SOA session goes into details on why she:

believes organizations need SOA more than before, but using a redefined SOA based on the SOA Manifesto, focusing on models, methodologies and patterns, not on technology, intended to produce the desired business and technical goals.

For a complete overview of SOA Symposium sessions on InfoQ check their SOA Symposium page.

Program SOA Symposium 2010 available

The agenda for the SOA Symposium 2010 has been posted. Again there are very interesting sessions during this 2 day conference. The largest and most comprehensive in the field of SOA and Cloud Computing. The Real World SOA Case Studies track offers a great opportunity to learn from the experience of others. In this track you will find:

Real-life accounts of successful and failed SOA projects discussed first-hand by those that experienced the project lifecycles and have a story to tell. These veteran practitioners will provide advice and insights regarding challenges, pitfalls, proven practices, and general project information that demonstrates the intricacies of implementing and governing service-oriented solutions in the real world.

I will be presenting the first session in this track on Using a Service Bus to Connect the Supply Chain. If you have any topics or questions in advance that you think I should address, please post them in the comments. Hope to meet you in Berlin.

SOA Symposium 2010 Call For Presentations

Definitions of Services and Processes

After once again looking for good, useful definitions of Services and Process decided to put them here for future reference.

Service Orientation – Paul Allen

The following definitions come from Service Orientation: Winning Strategies and Best Practices by Paul Allen.

A service is functionality that must be specified in the business context and in terms of the contracts between the provider of that functionality and its consumers. Implementation details should not be revealed. The implementation of the service does not have to be automated – it could consist of purely human activity.

A business process is a set of activities that is initiated by an event, transforms information or materials, and produces an output. These sets of activities are either value chains that produce outputs valued by customers or infrastructure processes that produce outputs that are valued by other processes.

With the remark that “a business process is usefully pictured as being composed of re-configurable services”.

A software service is a type of service that is implemented by software and that offers one or more operations (or software functuions).

Web services technology is a set of XML-based industry standards and specifications that specify a communication protocol (SOAP), a definition language (WSDL), and a publish-subscribe registry (UDDI).

Succeeding with SOA and Implementing SOA – Paul C. Brown

The following definitions were taken from Succeeding with SOA by Paul C. Brown. Who also wrote Implementing SOA.

A service is a unit of functionality packaged for convenience and consistent use.

With the remark that typically, this functionality consists of a body of information and a set of operations for managing this information.

A business process is a structured set of activities organized to produce results.
A process, or more specifically a discrete process, is a sequence of distinct activities that produces (or attempts to produce) discrete countable results.

An activity is a function performed by one or more agents that uses on or more inputs and produces one or more results.

SOA Design Patterns- Thomas Erl

This post could simply not exist without quotes from Thomas Erl. A complete list of his books in the Service-Oriented Computing series can be found on soabooks.com.

Services are collections of capabilities. A Service is a unit of solution logic to which service-orientation has been applied to a meaningful extent.
Services exist as physically independent software programs with specific design characteristics that support the attainment of the strategic goals associated with service-oriented computing.

A Web service is a body of solution logic that provides a physically decoupled technical contract consiting of a WSDL definition and one or more XML Schema definitions and possible WS-Policy expressions
In a Web service Capabilities are exposed as operations.

A business case for Service Orientation by Audi

Audi S5 - make reuse work

Audi S5

For me it is great to see the benefits of principles like reuse outside of IT. In this post i’ll share another example. Recently I read an article (in Dutch) on the success of Audi. Audi managed to keep up it’s sales even during 2009 (Annual Report 2009 PDF Alert 16MB!). Audi delivered 949,729 (compared to 1,003,469 in 2008) cars to customers worldwide in 2009. Sales were thus only 5.4 percent down on the record level of 2008 (source).

Besides innovation it is said in the Dutch magazine Management Team that reuse is one of the driving forces. It is great to have another example of how the principles behind Service Orientation not only deliver value in IT but also – or probably mainly – for the business when applied e.g. in other engineering disciplines.

Reusable building blocks

Audi has limited the number of modules engineer are allowed to use to construct a new model. There are two main lines, based on how the engine is placed:

Limiting the number of construction modules for engines, gearboxes, air conditioning results in several benefits:

  • Lower costs per car compared to it’s competitors.
  • Serve a larger number of niche markets compared to the competition.
  • Shortened time-to-market.
  • At production lines both employees and robots can work on several models. This enables Audi to produce the models that are in demand, while at the same time keeping a high utilization rate.

Audi claims to save 20% per manufactured car, and to save 30% on the development of new models. The economies of scale are further leveraged because of the reuse of components in the Volkswagen Group.

InfoQ on the SOA Manifesto

In October 2009 I posted about the announcement of the SOA Manifesto during the SOA Symposium 2009. For those of you interested, InfoQ has interviewed the original author’s and in some cases pulled in their comments on the manifesto from the web to get insight into the motivations and the process behind the initiative. The answers are gathered under the name SOA Manifesto – 4 months after. The article looks into the following subjects:

  • The philosophy
  • The process
  • The goals
