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 layer (integration, messaging, API management, and service connectivity). These services represent common middleware functions: AWS Lambda and Azure Logic Apps for integration/orchestration, Apigee for API management, and OIC for enterprise integration. They are not identical, but each can act as middleware depending on the use case.
