“Serverless” computing describes the latest wave of (cloud-) application platform technologies, where the complete responsibility for running and scaling the platform infrastructure hosting the application code is taken on by a cloud provider. The greatest upside of “serverless” platforms is that they provide an architectural harness that enables more developers to build highly scalable applications, and ready-made tooling to operate them. Serverless apps are increasingly interconnected with eventing and messaging infrastructures that take care of robust, high-scale data flows into and between app services and functions. In this talk, Clemens Vasters, Messaging Architect at Microsoft and standards architect working on OASIS AMQP and CNCF CloudEvents, will discuss the role of events and messaging in “serverless” and how the combination enables “the extensible enterprise” – enabling businesses to rapidly build and run extensions to their core application portfolios with minimal complexity
