Service Mesh: The Rise of Event-Driven Asynchronous Mesh in Cloud Continuum

The proliferation of microservice-based IT applications has increased the complexity of big data processing within any modern cloud application, requiring new strategies for managing, controlling, and accelerating deployments. Service Meshes offer new management support that facilitates control over a very large number of services while separating logic from control specification. Applications becoming more decentralized and deployed across multiple regions in the cloud continuum ask for even more uncoupled and asynchronous interactions to enhance reliability and scalability. Event-driven architectures offer a viable solution; consequently, Event Meshes emerge as a cloud paradigm promoting event-based, asynchronous interactions among services and data. This article compares Service Mesh and Event Mesh approaches, claiming that Event Meshes improve uncoupling and offers asynchronous behavior in distributed systems to optimize performance in traffic management, observability, and security.
