Microservices

Topics such as application resiliency, self-healing, antifragility are my area of interest. I've been trying to distinguish, define , and visualize these concepts, and create solutions with these characteristics. Software characteristics"> However, I notice repeatedly, that there are various conference talks about resiliency, self-healing, and antifragility and often they lazily conclude that Netflix OSS Hystrix is the answer to all of that. It is important to remember that conference speakers are overly optimistic, wishful thinkers, and it takes more than...

An introduction to microservices through a complete example Today I want to talk about the demo we presented @ OpenShift Container Platform Roadshow in Milan & Rome last week. The demo was based on JBoss team's great work available on this repo: https://github.com/jbossdemocentral/coolstore-microservice In the next few paragraphs, I'll describe in deep detail the microservices CoolStore example and how we used it for creating a great and useful example of DevOps practices. We made some edits to the original project...

John Frizelle, a Mobile Platform Architect at Red Hat, gave a talk on microservices wherein he provided some great advice about microservices. Most importantly, he provided guidance on when, where, and why (or why not) you should deploy them. What are Microservices Microservices are a method of breaking down an application into a suite of small, lightweight services, and are processes that typically communicate over HTTP. Building a single microservice is easy, building a microservice architecture is extremely hard. It...

Recently, the focus on the continuous delivery of value has created a lot of interest in microservices, CI/CD, and containers. The idea is that microservices are small and well defined enough to enable rapid innovation, automated testing, and frequent deployments with minimal risk. This is made possible by adopting continuous integration and continuous delivery pipelines. CI/CD requires the ability to quickly, easily, reliably, and automatically create and tear down complete execution environments. Linux containers address this need by creating lightweight...

... with APIs, OpenID, and Microservices, Daria Mayorova and Mark Cheshire from Red Hat 3Scale shared their presentation on how to construct microservice-based applications with the benefits of API management. Some general characteristics of microservices include: componentization via service organized around business capabilities smart endpoints design for failure decoupling of components Typically, microservices are divided into to two general architectural buckets: Inner Architecture Any service communication with other microservices within a larger service boundary (think intra-application communication). Outer Architecture Border...

Yesterday, at Red Hat Summit , Red Hat announced OpenShift.io . OpenShift.io is the next generation OpenShift platform, based on OpenShift 3, for building and running applications in the cloud. It gives you complete control of your application's lifecycle, from build to production-- regardless of deploying from source or running a pre-built container. In the Developer tools, Overview and Roadmap Part I summit session, Todd Mancini, Peter Muir, and James Strachan take a packed house through an introduction to OpenShift.io...

Today's announcement of Red Hat OpenShift.io was followed by a full day of developer toolset Summit sessions. These were presented by the OpenShift.io product development team and covered some truly amazing OpenShift.io features. While there are too many features to cover in a single blog post, these were my top 7 items. 1. A Kanban board that is actually useful OpenShift.io is built from the ground up for development teams to rapidly release software. This is one of the primary...

Digital transformation is about evolving into a technology business to compete in the digital economy. Businesses can’t transform without relying on the developer to implement the transformation strategy and deliver value. Unfortunately, as developers look to adopt new approaches that let them deliver business value more quickly, they find it challenging to get started in a timely fashion. First, they have to pick a software stack to use as a foundation. In the world of open source, there is an...

Red Hat Summit is just around the corner in Boston and we are preparing just a few of the many Red Hat authors for their book signings. We've given them 6 steps to signing books: Step 1: Get books ordered. Step 2: Get to Boston. Step 3: Bring a marker. Step 4: Bring a spare marker. Step 5: Show up at the right time. Step 6: Enjoy sharing your work with attendees! Ok - so we may be teasing them...

It’s hard to believe that spring of 2017 is upon us, and with it, the preparation for our second DevNation Federal . Last year has seen a surge of innovation in open source communities, and now more than ever it’s imperative that government agencies equip themselves for the change that lies ahead. This year, digital transformation , microservices , containers and Kubernetes are hotter than ever. Function as a Service (FaaS) , hyper-converged , and serverless architecture are on the...

So recently, the idea that Monoliths should be discouraged and that Microservices be embraced has taken over the Software Development space. A project made into a single code base is to be taken out and broken into manageable pieces. It is better to work with manageable sub-units than a whole bunch of one big stuff. Well, as the saying goes, small-scale always wins. Before you consider starting that project or breaking your current project into microservices, you have to fundamentally...

Introduction The OpenShift Java S2I image, which allows you to automatically build and deploy your Java microservices, has just been released and is now publicly available. This article describes how to get started with the Java S2I container image, but first, let’s discuss why having a Java S2I image is so important. Why Java S2I? The Java S2I image enables developers to automatically build, deploy and run java applications on demand, in OpenShift Container Platform, by simply specifying the location...

Today, I am very pleased to announce the GA of Fuse Integration Service 2.0. This release will make integration applications more portable, flexible and allow agile developers to react faster to business needs by supporting microservice architectures. Developers will now be able to realize the benefits of microservices within integration projects and be able to leverage integration patterns while breaking up monolithic applications and reducing the size of services pushed onto older ESB technology. With FIS 2.0, developers can now...

As a consultant for Red Hat, I have the privilege of seeing many customers. Some of them are working to find ways to split their applications in smaller chunks to implement the microservices architecture. I’m sure this trend is generalized even outside my own group of the customers. There is undoubtedly hype around microservices. Some organizations are moving toward microservices because it’s a trend, rather than to achieve a clear and measurable objective. In the process, these organizations are missing...

For businesses looking to build scalable Internet of Things (IoT) solutions using containers, here is a sample project built on the Red Hat OpenShift Container Platform . This project implements an intelligent IoT gateway on the OpenShift Container platform. The IoT Gateway is critical for enterprise IoT as it brings intelligence, and enables key services, at the edge. In this project, the gateway application is deployed as a set of microservices inside containers on OpenShift. A software sensor sends a...

2017: Time for a new resolution and the most important resolution for this year should be to adopt microservices to spend less effort on development and improve your time to market (TTM) . Nowadays, there are plenty of tools and frameworks at the disposal of the discerning developer to rapidly build microservices. A few examples include Spring Boot, Vertx, etc. Once you build your microservices, the next step is to ensure that these frequent deployments do not impact the availability...

The CDK 2.3 version has added the newest OpenShift Container Platform 3.3, allowing us to make use of the Jenkins Pipeline builds as well a special route configuration, which enables A/B deployments. In this post, I will show you how to achieve that configuration using a microservice application. Preparation steps Once CDK 2.3 is up and running in our environment, we need to make an additional configuration to enable the Jenkins pipeline builds. Since it is an experimental feature, it...

To get started with FIS 2.0, for people who are just getting to know the technology, here is how I interpret it. Basically, it's divided into two aspects. 1. Integration development: FIS uses Apache Camel as the core technology that creates, orchestrates, and composes microservices into a super lightweight thin integration layer, and becomes the API provider and service orchestrator through exposing RESTful or messaging service endpoints. And you can choose to either package and run it with Spring-Boot or...

Red Hat Fuse Integration Service 2.0 tech preview was released a few weeks ago and as it's based on Red Hat OpenShift 3.3, which has pipeline capability on top of it (tech preview on OpenShift as well), you are able to get one step closer to a more automated and agile continuous integration. As well as, a deployment one-stop platform for us, the integration developer. For the pipeline to work on OpenShift, you need Jenkins installed and running. OpenShift uses...

The tutorial Spring Boot and OAuth2 showed how to enable OAuth2 with Spring Boot with Facebook as AuthProvider; this blog is the extension of showing how to use KeyCloak as AuthProvider instead of Facebook. I intend to keep this example as close to the original Spring Boot and OAuth2 and will explain the changes to the configuration to make the same application work with KeyCloak . The source code for the examples are available in the github repositories listed below...

Eclipse Vert.x is a toolkit used to build reactive and distributed systems on the Java Virtual Machine. Vert.x supports a variety of languages letting you choose which one you’d prefer. The Vert.x Core cheat sheet covers the creation of a project using Apache Maven, Gradle or the Vert.x CLI, and references most common Vert.x Core APIs, in 3 different languages (Java, JavaScript, and Groovy). Forgot how to create an HTTP server, use the HTTP client, implement a request-response on the...
