Legacy architectures often use synchronous, batch, scheduled communications, performing pooling - which results in waiting time for responses and costs of using computing resources.
This communication model presents constraints to achieving the agility and scalability required by digital businesses, which need to operate in complex partners and internal application ecosystems.
In these contexts, the ability to respond in real-time to threats and opportunities can dramatically improve the customer experience and business results.
This requires competence in propagating, capturing, analyzing, and reacting immediately to ecosystem events using event-driven architecture (EDA) and asynchronous communications.
More than agility and scalability for digital business, event-driven architectures also enable extensibility, resiliency, and reductions in computational costs.
These qualities impact an organization's ability to innovate, which can be accelerated or constrained by the IT architecture - which should enable changes, tests and releases to be executed quickly.
EDAs are based on stand-alone components, which when altered or in case of failure have minimal impact on the environment and achieve faster recovery. Thus, EDAs reduce costs and risks, boosting innovation.In addition, new technologies such as IoT, AI, Microservices and Blockchain are already event-driven. Being familiar with EDA favors the adoption of these new technologies.
Event-driven architectures do not completely eliminate request-response interactions. Both approaches are necessary, complementary, depending on the scenario and the business need.
Properly combined, these approaches allow you to react and capitalize on "digital business moments" in real-time, leverage digital ecosystems by propagating events to all participants, and build a modern integration architecture capable of sustaining the rapid pace of innovation required by digital businesses.
