Application Modernization and SOA Concepts Training and Courseware

Quick Enroll

Course#: WA1657

This 2-day course will explore the trend around ‘application modernization’ and introduce you to a wide range of techniques and strategies for modernizing legacy systems including Service Oriented Architecture (SOA), Business Process Management (BPM), Web services, Message Oriented Middleware (MOM), and Web 2.0. Special emphasis will be giving to SOA and service-based solutions for modernizing legacy systems. 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 risks, opportunities, and challenges that exist in modernizing legacy assets such as mainframes, database stored procedures, flat-file systems, customized vendor packages, and other home-grown solutions. Finally, attention will be given to the subject of skills modernization, how to bridge the education gap, and acquire the needed skills for supporting and enabling modern enterprise systems.

Concepts in this workshop are re-enforced through a combination of group discussion, class exercises, case study explorations, and daily reviews.
