Software that connects different applications, services, or systems to help them communicate and share data. Like a translator that helps two people speaking different languages understand each other.
Middleware connects your mobile banking app to the bank's database systems, translating requests and ensuring secure communication.
Middleware is a broad concept (integration, messaging, API gateways, service mesh). These services are common cloud-managed middleware options focused on connecting apps via APIs, handling authentication, routing, throttling, and request/response transformation. Other middleware categories include message brokers (e.g., Amazon MQ/Azure Service Bus/Pub/Sub/OCI Streaming) and service mesh (AWS App Mesh/Istio on AKS/Anthos Service Mesh/OCI Service Mesh).
