7 Field notes on modernization for  application integration  In this chapter, we explore various guidance points for customers who plan to modernize their  application integration landscape. The target audience for this chapter is individuals who are  already skilled in IBM App Connect (or its predecessors such as IBM Integration Bus,  WebSphere Message Broker). We explore at a product level what it means to move to a more  agile integration style. For example, such a move includes a move to container technology,  refactoring to more fine-grained deployment, and automation of build pipelines.
