Our connected world is full of events that are triggered or received by different software services. One of the big issues is that event publishers tend to describe events differently and in ways that are mostly incompatible with each other.

To address this, the Serverless Working Group from the Cloud Native Computing Foundation (CNCF) recently announced version 0.2 of the CloudEvents specification. The specification aims to describe event data in a common, standardized way. To some degree, a CloudEvent is an abstract envelope with some specified attributes that describe a concrete event and its data.

Working with CloudEvents is simple. This article shows how to use the powerful JVM toolkit provided by Vert.x to either generate or receive and process CloudEvents.

State of Functions-as-a-Service on Kubernetes (OpenShift Commons Briefing)

State of Functions-as-a-Service on Kubernetes (OpenShift Commons Briefing)

If you are interested in serverless computing / Functions-as-a-Service (FaaS), and are not following the OpenShift blog, you should checkout The State of Functions-as-a-Service on Kubernetes.  This video is part of the OpenShift Commons Briefing series, which has a lot of great content for developers who interested in cloud-native applications and microservices running on OpenShift and Kubernetes.

FaaS, or serverless as some call it, is a promising compute paradigm suitable for event-driven scenarios. In this briefing, Red Hat’s Michael Hausenblas and Brian Gracely reviewed the current open source offerings for FaaS on Kubernetes (Apache Open Whisk, kubeless, OpenFaaS, etc.) and discussed the pros and cons, on an architectural level and a user experience (UX) point of view. They also covered the topic FaaS vs. containers from a developers as well as an operators perspective.

This talk builds on material gathered by the Serverless Working Group , which is part of the Cloud Native Computing Foundation (CNCF). CNCF serves as the vendor-neutral home for many of the fastest-growing projects on GitHub, including Kubernetes, Prometheus, and Envoy.
