Training

• Service elements and attributes
• Performance, scalability, and reliability
• XML limitations
• XML performance options
• Web service performance strategies
• Non-XML services
• Non-HTTP services
• Topology, tools, and infrastructure
• Requirements, testing, and verification
• Designing for performance
• Governing service performance

After completing this course, the student should be able to:

• Identify the key elements of a service and debunk service myths
• Understand the tradeoffs, ambiguity, and common confusion regarding responsiveness, scalability, and reliability
• Describe the limitations inherent in XML-based communication
• Identify the options available for optimizing and accelerating XML messaging
• Work with non-XML services
• Identify key strategies for designing higher performing web services
• Identify key components within a service oriented infrastructure and various vendor offerings
• Gather responsiveness, scalability, and reliability requirements
• Test Web services and record performance metrics
• Govern Web services from a performance and scalability perspective

This course is applicable to Architects, Developers, Systems Administration personnel, and anyone else involved in designing, developing, and supporting high performance Web service environments.

A working knowledge of XML, WSDL, SOAP, and HTTP is required.  An understanding of other WS standards and technologies is helpful, but not required.  Previous hands-on experience is recommended, but not explicitly required.
