Serverless

In this webinar, we’ll review Knative.

Julien Ponge's upcoming book, Vert.x in Action: Asynchronous and Reactive Applications in Java, is now available from the Manning early-access program (MEAP). Read the article for the exclusive Red Hat Developer discount code.

This post is the first in a series that describes a lightweight cloud-native distributed microservices framework called EventFlow that targets the Kubernetes/OpenShift platforms and models event-processing applications as a connected flow or stream of components. EventFlow can be used to develop event-processing applications that can process CloudEvents, which are an effort to standardise upon a data format for exchanging information regarding events generated by cloud platforms.

Serverless architectures can benefit from faster startup times. The configuration demonstrated in this article shows how GraalVM can reduce startup time and Docker image size for Java-based programs hosted on container platforms such as Red Hat OpenShift Containter Platform.

In this session we will start to see what Serverless is and what it means to you.

The next online DevNation Live is June 7th at 12pm EDT for "Your Journey to a Serverless World—An Introduction to Serverless", presented by Kamesh Sampath and hosted by Burr Sutter.

Red Hat Senior Architects Marius Bogoevici and Christian Posta recently presented an overview of event-driven architecture, taking the audience from the basics of enterprise integration to microservices and serverless computing.

In this session we get started using Function as a Service (FaaS) engine with Apache OpenWhisk deployed on Kubernetes and OpenShift.

The next online DevNation Live Tech Talk will be Thursday, May 17th at 12 p.m. EDT. The topic is " Serverless and Servicefull Applications: Where Microservices Complements Serverless" presented by Burr Sutter.

Serverless computing (often called Functions as a Service, or FaaS) is one of the hottest emerging technologies today. The OpenWhisk project, currently in incubation at Apache, is an open-source implementation of serverless that lets you create functions that are invoked in response to events.

Senior Director Stephanos Bacon discussed the changing developer landscape and the factors that influence it. As cloud computing becomes ubiquitous and serverless continues to grow, more changes are in store.

You're in an IT department. How does the rest of the organization see you? As a valuable asset whose code and APIs make a difference in the marketplace, or as a necessary evil that should be trimmed wherever possible? Containers, microservices, and serverless computing can get you where you need to go.

If you are interested in serverless computing / Functions-as-a-Service (FaaS) Red Hat’s Michael Hausenblas and Brian Gracely reviewed open source for FaaS on Kubernetes (Apache Open Whisk, kubeless, OpenFaaS) and discussed the pros/cons on an architectural level as well as from a UX)point of view.

In this blog we will see how to build a simple nodejs function that can do a reverse geocoding using GoogleMaps API.,and deploy the functions on to OpenWhisk

Want to take advantage of the type-safety and expressiveness of Java 8 lambda expressions to write queries that would be executed on a data store? It’s not as simple as it sounds. During this session, we’ll talk about the challenges behind using such expressions (spoiler: this includes reading bytecode). We’ll show you how to integrate lambda expressions with the latest MongoDB Java driver to submit queries in the native BSON format on the data store.
