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.

Red Hat Summit 2018 to focus on Modern App Development

On behalf of the selection teams for Modern Application Development, I am pleased to share this exciting, dynamic, and diverse set of developer-related breakouts, workshops, BoFs, and labs for Red Hat Summit 2018.

With these 61+ sessions listed below, we believe that every attending application developer will come away with a strong understanding of where Red Hat is headed in this app dev space, and obtain a good foundation for tackling that next generation of apps. Encompassing various aspects of Modern App Dev, some sub-topics we’ve focused on are around microservices, service mesh, security and AI/ML, plus there is a large collection of complementary and related topics.

So…if you’re an application developer, we invite you to attend Red Hat Summit 2018 and experience the code first hand. There’s something for everyone and definitely something for you. Register today.

Great talks don’t happen without great speakers, and we feel really privileged to have these popular, high-in-demand speakers:

Whisking Functions with Promises using OpenWhisk

Over the past few weeks I have been learning and enhancing my skills around the new buzz word “serverless” and trying to understand what this buzz is all about.  As an ardent open-source developer, I was looking for a platform where I can develop and deploy the serverless functions, which is when I stumbled upon Apache OpenWhisk.

In this blog I will demonstrate how to build a simple nodejs function that can do reverse geocoding using Google Maps API, and how to deploy the functions on to Apache OpenWhisk.

The context is to show building an Apache OpenWhisk JavaScript action, which involves a callback.  As most of us are familiar with Google Maps API (which has lots of callbacks), it provides a good example for this blog.

Red Hat and Apache OpenWhisk

Unless you’ve been on a complete media blackout for the last year or so (entirely understandable) you’ve likely heard a lot about Serverless (or FaaS – Function as a Service). Serverless is a major shift in the way developers build and deliver software systems – it greatly simplifies development by insulating the developer from infrastructure concerns and pushes the envelope on cost and efficiency of execution.
