Many enterprises have heavily invested in open source and proprietary Java EE technologies, and this has affected everything from how they hire software talent to training, tooling, and management. Java EE has always been very capable at helping developers build tiered applications by offering functionality like servlets/JavaServer Pages (JSPs), transactions, component models, messaging, and persistence.
Despite its popularity, recently the feeling began to grow that Java EE’s pace of innovation was too slow for a world that demanded cloud-native applications, microservices, and containers. This feeling prompted various Java User Groups, Java Champions, vendors, and corporations to join forces and release the MicroProfile specification.
