The Reconstitution of Middleware with APIs
1 like386 views
The document recounts Asanka Abeysinghe's presentation at the Integration Summit 2019, where he discusses the evolution of middleware and its integration with APIs. He highlights that middleware, traditionally seen as 'software glue', is transforming into simpler constructs and infrastructure, leading to its eventual disappearance. Additionally, he introduces Ballerina and Cellery, innovative platforms that facilitate cloud-native programming and microservices integration.

- 10. Middleware is computer software that provides services to software applications beyond those available from the operating system. It can be described as "software glue”. Middleware makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application.

- 37. A cloud-native programming language for microservices and APIs - A compiled, transactional, statically and strongly typed programming language with textual and graphical syntaxes. - Incorporates fundamental concepts of distributed system integration - Offers a type safe, concurrent environment to implement microservices with distributed transactions, reliable messaging, stream processing, and workflows - Compiles into container images for deployment on Kubernetes and Docker https://ballerina.io/
