Application Modernization and Service Oriented Architecture(SOA) Concepts - IBM tools Course

This course will explore the trend around ‘application modernization’ and introduce the attendees 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. Participants 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 homegrown 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.

Upon completion of this course, the participant will be able to:

> Gain an understanding of SOA concepts and key elements
> Learn the importance of BPM and governance to a successful SOA
> Understand the core qualities of services and when and how they benefit the enterprise
> Explore the subject of application modernization
> Discuss and examine the advantages and disadvantages of various modernization techniques
> Understand how legacy systems can support and enable a SOA
> Learn the process of modernizing legacy systems
> Explore the key concepts, technologies, and infrastructure elements that provide the foundation for modern enterprise systems
