Speaking on Advanced Software Architecture

Presentations

The following presentations may be individual keynotes or they may be assembled with consulting services into one-day or multi-day programs. 

Web Services in Context

This presentation is an overview of Web Services, related standards, and technologies that can be used in service-oriented architectures. This presentation introduces the concepts of Web Services at a high level and then focus on the current state standards and which technologies make sense in a service-oriented architecture. One feature of this presentation is showing how Web Services address many of the technical barriers to systems integration.

Length: 60 to 90 minutes

Prerequisite: None

Audience: Non-technical management, technical management, and technical staff

Outline:

1. Service-oriented architectures are not new
2. The breadth of adoption of service-oriented architectures using Web Services is new
3. Service-oriented architecture explained
   1. Services
   2. Connections
4. Historical context for service-oriented architectures
5. Blurring of internal and external services
6. Web Services Explained
   1. Using the Web Services Description Language (WSDL)
   2. Using Universal Description, Discovery, and Integration (UDDI)
   3. Using SOAP
   4. Using XML with WSDL
7. Importance of semantic vocabularies
   1. Common semantic vocabularies
   2. Specific semantic vocabularies
   3. Importance of being involved in the development of industry vocabularies
8. Status of Web Services standards
9. Future directions

Forces Affecting the Adoption of Web Services: A comparison to other integration techniques

This presentation shows the use of force-field analysis to help get a perspective on the forces affecting the adoption of Web Services and other integration techniques. Common system integration techniques will be presented approximately in chronological order. Chronological order allows us to see how, over time, advances in technology and standards have diminished the number of restraining forces, making change more likely to occur. Web Services will be shown as having the least number of restraining forces compared to any of the prior techniques. This is a great way to illustrate why Web Services can be seen as a wave of change in the software industry.

Length: 60 to 90 minutes

Prerequisite: General understanding of Web Services (the Web Services in Context presentation or equivalent)

Audience: Non-technical management, technical management, and technical staff

Outline:

1. Force-field analysis overview
2. Analysis of integration techniques
3. Analysis of adopting enterprise-wide standards
   1. Adopting standard data element definitions
   2. Adopting standard, enterprise-wide software
4. Analysis of middleware integration
   1. Adopting CORBA or DCOM
   2. Adopting Web Services
5. Analysis of additional components used for integration in a service-oriented architecture
   1. Analysis of data warehousing
   2. Analysis of application or message routing
6. Analysis of putting all the integration techniques together in a service-oriented architecture

Evolution of Information Technology: The likely impact of Web Services and service-oriented architectures

The use of Web Services has the potential to change IT as we know it. This presentation describes several change scenarios and how they will affect IT as well as other parts of an organization. It also provides suggestions on how to position your organization to take advantage of the opportunities presented by the changes related to Web Services.

Length: 60 to 90 minutes

Prerequisite: The Forces affecting the Adoption of Web Services presentation

Audience: Non-technical management, technical management, and technical staff

Outline:

1. Initial impact of Web Services
2. Evolutionary use
3. Discussion of change
4. Technical change issues diminishing
5. Non-technical change issues may ncrease
   1. Resistance to change
   2. Overcoming resistance to change
6. Change scenarios
7. Consolidated force-field analysis for adopting a service-oriented architecture that includes change issues
8. Tips for managing change issues during development

Enterprise Service-Oriented Architecture: Options for deployment

There are many options for deploying an enterprise service-oriented architecture. This presentation emphasizes middle-tier architectures and provides architectural options. It covers relevant data access standards and emerging specifications.

Length: 60 to 90 minutes

Prerequisite: General understanding of Web Services (the Web Services in Context presentation or equivalent)

Audience: Technical management and technical staff

Outline:

1. Integration with existing architectures
2. Classification of data-centric and process-centric architectures
3. Middle-tier architectural options
   1. Caching options
   2. Persistence options
   3. Firewall options
4. Relevant data access standards and specifications

Designing a Service-Oriented Architecture: How to incrementally implement Web Services

This presentation will show you how to incrementally adapt your systems into services. It is often surprising to see how differently your systems architecture may look when viewed through the lens of a service-oriented architecture. Example architectures will be used to illustrate how to incrementally move from your existing systems to a service-oriented architecture. 

This presentation builds on the material from the Enterprise Service-Oriented Architectures: Options for deployment presentation and relates it to the material in the Evolution of Information Technology: The likely impact of Web Services and service-oriented architectures presentation.

Length: 60 to 90 minutes

Prerequisite: Basic understanding Web Services standards and related products (the Enterprise Service-Oriented Architectures: Options for deployment presentation or equivalent) and the Evolution of Information Technology: The likely impact of Web Services and service-oriented architectures presentation

Audience: Technical management and technical staff

Outline:

1. Applying the stages of adoption for using Web Services to incrementally implement a service-oriented architecture
   1. Experiment with Web Services
   2. Adapt existing systems to use Web Services
   3. Remove intersystem dependencies
   4. Establish an internal service-oriented architecture
   5. Expand the internal service-oriented architecture to include external services
2. Each stage will be illustrated using:
   1. Architectures
   2. Staffing suggestions
   3. Likely change issues and suggestions for dealing with those issues

Roundtable Discussions

This interactive session is designed to provide participants with the opportunity to get answers for their burning questions in a real-time setting. Any topic related to Web Services and service-oriented architectures is appropriate.
