Enterprise integration is a data challenge, especially in organisations where the term Big Data refers to the size and variety of their data sources. While a large volume of data existing in a variety of nonstandard formats provides significant business value, it must be integrated from multiple sources or applications. The Internet of Things (IoT) also represents a new opportunity to connect with customers and analyse useful data through everyday devices. However, the critical data that needs to go to the data centre must be filtered out. Web applications can further add to the complexity of enterprise integration when legacy applications must be tied to a service-based architecture such as microservices.
