Bringing Coolstore Microservices to the Service Mesh: Part 2–Manual Injection

By James Falkner April 12, 2018April 12, 2018

Coolstore+Istio Logo

In the first part of this series we explored the Istio project and how Red Hat is committed to and actively involved in the project and working to integrate it into Kubernetes and OpenShift to bring the benefits of a service mesh to our customers and the wider communities involved. If you want to play with Istio, check out the service mesh tutorials on learn.openshift.com. If you want to install it, follow the Istio Kubernetes quickstart instructions and install it on OpenShift 3.7 or later. Also don’t miss Don Schenck’s series of blogs on Istio technology in general to learn more about it and what Red Hat is doing in this space.

In this post, we will deploy the existing Coolstore microservices demo as a service mesh and start to demonstrate the tangible value you can get out of the system without any major rewrite or rearchitecture of the existing app. We’ll also improve our project along the way to adhere to Istio (and general microservice) best practices. In the real world, your applications and developers often make bad assumptions or fail to implement best practices, so with this information you can learn something about your own projects. For Coolstore, many of these workarounds will eventually find their way into the source code of the demo.

An API Journey: From Idea to Deployment the Agile Way–Part I

By Laurent Broudoux April 11, 2018April 11, 2018

The goal of this series of posts is to describe a proposed approach for an agile API delivery process. It will cover not only the development part but also the design, the tests, the delivery, and the management in production. You will learn how to use mocking to speed up development and break dependencies, use the contract-first approach for defining tests that will harden your implementation, protect the exposed API through a management gateway and, finally, secure deliveries using a CI/CD pipeline.

Istio Chaos Engineering: I Meant To Do That

By Don Schenck April 10, 2018April 12, 2018

If you break things before they break, it’ll give you a break and they won’t break.

(Clearly, this is management-level material)

Accessing Data – The Reactive Way

By Clement Escoffier April 9, 2018

This is the fourth post of my “Introduction to Eclipse Vert.x.” series. In this article, we are going to see how we can use JDBC in an Eclipse Vert.x application using the asynchronous API provided by the vertx-jdbc-client. But before diving into JDBC and other SQL subtleties, we are going to talk about Vert.x Futures.

In “The Introduction to Vert.x” Series

Let’s start by refreshing our memory about the previous articles:

The first post described how to build a vert.x application with Maven and execute unit tests.
The second post reviewed how this application became configurable.
The third post introduced vertx-web, and a collection management application was developed. This application exposes a REST API used by an HTML/JavaScript frontend.

A Cloud Lab Environment in a Backpack

By Marcelo "Ataxexe" Guimarães April 9, 2018April 9, 2018

Have you ever thought about having your own cloud environment? A local cloud is one of the best things you can do to better understand all the gears that run inside a highly productive environment. How do I know that? I’ve done it! And I’m ready to show you how I did, and how you can do it too.

Red Hat Summit 2018: Develop Secure Apps and Services

By Mike Guerette April 6, 2018April 6, 2018

Red Hat Summit 2018 will focus on modern application development. A critical part of modern application development is of course securing your applications and services. Things were challenging when you only needed to secure a single monolithic application. In a modern application landscape, you’re probably looking at building microservices and possibly exposing application services and APIs outside the boundaries of your enterprise. In order to deploy cloud-native applications and microservices you must be able to secure them. You might be faced with the challenge of securing both applications and back-end services accessed by mobile devices while using third party identity providers like social networks. Fortunately, Red Hat Summit 2018 has a number of developer-oriented sessions where you can learn how to secure your applications and services, integrate single-sign on, and manage your APIs. Session highlights include:
