You Will Learn How To
- Implement and manage modern Service-Oriented Architectures (SOA)
- Exploit SOA technology to reduce application development time and improve business agility
- Leverage architecturally sound best practices to integrate services with contemporary object-oriented software
- Automate complex business processes using workflow visualisation and service orchestration
- Apply proven SOA standards to achieve platform interoperability and integration of legacy systems
- Govern SOA reliability, performance and security throughout the enterprise
Course Benefits
Modern software combines discrete and disparate programs into interoperable, distributed applications implemented into Service-Oriented Architectures (SOAs). This reduces application development time and enhances business agility. In this course, you gain a foundational understanding of the concepts necessary to model, implement and strategically deploy an SOA within your organisation by applying methodologies, technologies and standards.
Who Should Attend
Analysts, strategists, software architects and anyone seeking a foundational understanding of SOA. A general understanding of software development and basic programming experience is required.
Hands-On Training
In this course, you perform a series of simulations and hands-on exercises, including:
- Manually performing the steps of a business process to analyse for automation
- Investigating requirements and identifying service opportunities
- Validating XML documents using a schema
- Publishing SOA interfaces with WSDL documents
- Generating BPEL scripts to realise business logic
- Implementing Web services using Java EE and .NET
- Developing loosely coupled service requesters.
