Businesses constantly need to enhance customer experiences. This requires them to digitally transform and provide services in a timely, personalized manner. That's why businesses need to become integration agile in order to create business agility and overcome challenges to meet customer demands. In this tutorial, we will explore a use case where an airline is trying to enhance its customer experience by making various airline information services available to customers and allowing them to manage their travel experience. We will define a real-world use case where a traveler wants to interact with an airline system via a web portal and mobile app. To facilitate the integration requirements for these client-facing applications, we will define a solutions architecture that interacts with disparate back-end systems. This architecture will be based on WSO2 Enterprise Integrator, WSO2 API Manager, WSO2 Identity Server, and WSO2 Stream Processor. We will also show how to make use of DevOps and CI/CD techniques in general to achieve agility.
