The Reconstitution of Middleware with APIs V2
- Middleware is disappearing into code and infrastructure. Code is using simpler constructs with more power, while infrastructure provides scaling, management, and observability. - APIs are becoming the glue that connects microservices deployed in a decentralized architecture. - The speaker has contributed to open source projects like Ballerina and WSO2 Choreo, and shares knowledge through blogs, LinkedIn, and evangelizing reference architectures for cloud-native applications.

- 16. Middleware is computer software that provides servicesto 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.
