This 3-day course will introduce you to SOA (Service Oriented Architecture), one of the most popular business initiatives among corporations and government organizations today. Service Oriented Architecture provides a more agile and comprehensive way to integrate information systems and businesses processes than more traditional approaches. Students will be exposed to a broad range of enterprise SOA subjects, providing a solid foundational understanding of both business and technology elements of SOA.
Concepts in this workshop are re-enforced through a combination of group discussion, class exercises, case study explorations, and daily reviews.
Course Objectives:
Gain an understanding of Service Oriented Architecture
Learn the importance of BPM and governance to a successful SOA
Explore the technology and business impacts of SOA
Understand the SOA value proposition
Learn the lifecycle for services and understand the challenges
Gain a knowledge of security, testing, and information management within SOA
Explore the relative maturity of SOA and models for gauging the maturity of an organization’s SOA initiative
Course Prerequisites
There are no formal knowledge prerequisites.
Who Should Attend?
This course is applicable to both technical and business personnel. It provides a general foundation in Service Oriented Architecture (SOA) and addresses a wide range of enterprise elements and job roles.
