One of the main principles of microservices is to be independently deployable. As a consequence, Microservices development and operation tend to be much more complex than a Monolith because of their distributed nature --- if your IT team has not moved out yet from its silos and has adopted DevOps practices, the operations team will not really understand why they have to deploy hundreds of independent software pieces in opposite to the "good old monolith". "You need a mature operations...

Microservices are currently enjoying immense popularity. It is rare to find a tech conference without at least a few mentions of them in corridor conversations or titles of talks, and for good reason: microservices can provide a path to better, more maintainable, higher quality software delivered faster. What's not to love? Of course there are the "negatives" and details in the implementation of microservices that can trip up even the most seasoned architect-developer, but at the same time we are...

Cross language development in one project In this tutorial style article I'll discuss how to configure Eclipse for Java Native Interface (JNI) development based on a sample project that you can copy and modify. I.e, you can have a single project that can be both Java and C at the same time, and support a full code navigation and debugging of both languages. This article is focused on the configuration of Eclipse rather than explaining JNI itself, however there are...

The release of the latest JBoss Developer Studio (JBDS) brings with it the questions around how to get started with the various JBoss Integration and BPM product tool sets that are not installed out of the box. In this series of articles we will outline for you how to install each set of tools and explain which products they are supporting. This should help you in making an informed decision about what tooling you might want to install before embarking...

Generally when the topic of Business Process Management (BPM) comes up we think of BPM software suites. There’s another side to BPM though, and that’s the practice of process management, which doesn’t require any software at all. Traditionally the BPM practice has focused on continuous process improvement. There are various methodologies but it generally comes down to this: Collect metrics on the existing process Analyze those metrics Propose an optimization Simulate the optimization with the collected metrics Institute the validated...

One of our most popular Red Hat JBoss BRMS demo's, and one that has been available for quite some time, is the CoolStore demo. The CoolStore demo shows how business rules can be used to calculate values like promotional and shipping discounts in a shopping-cart. It furthermore illustrates concepts like ruleflow-groups and dynamic rule updates using KieScanner. Rules and micro-services: the JBoss BRMS Decision Server One of the more interesting features we've recently released in the Red Hat JBoss BRMS...

Red Hat, Inc. recently released the Red Hat SSO product, which is an enterprise application designed to provide federated authentication for web and mobile applications. In the SAML world, RH SSO is known as an Identity Provider (IdP), meaning its role in life is to authenticate and authorize users for use in a federated identity management system. For example, it can be used to authenticate internal users against a corporate LDAP instance such that they can then access the corporate...

Welcome to the third installment of That App You Love, a blog series in which I show you how to you can make almost any app into a first-class cloud citizen. If you want to start from the beginning, jump back and check out Part 1: Making a Connection. In Part 2 of this series, we looked at ZNC’s configuration options to decide which settings we wanted to expose to the user, and which settings we could hard-code straight into...

Fuse Integration Services (FIS) is a great product bringing routing (Apache Camel), SOAP and Rest services (CXF) and messaging (JMS) to the modern age of containers and PaaS and all its goodies: encapsulation, immutability, scalability and self healing. OpenShift provides the PaaS infrastructure to FIS. A developer may implement a module in isolation on his own machine, but it often makes sense, especially when we talk about integration services, to have the code being validated in a complex integrated environment...

Google Summer of Code (GSoC) is a yearly effort run by Google to bring students and open source projects together. Open source projects apply to be mentoring organizations. Google selects some organizations where students then apply. A limited number of them is selected to work on the projects. Each selected student gets a stipend from Google. This year Google has funded 1184 student projects for 178 organizations. Among the selected organizations were JBoss community and Vert.x with a total of...

Java language server is an implementation of the language server protocol for Java. If you recall, language server protocol provides a common way for editors and IDEs to integrate with language smartness providers. By design, all of the language tooling magic happens on the Java language server, and can provide same level of smartness to tools that support the protocol. In fact, we are working with communities such as Eclipse Che to make this server available for their tools. As...

In order for businesses to stay agile, developers must be able to deploy apps -- quickly, efficiently, and in a streamlined manner. Red Hat Open Innovation Labs uses a container-driven application development framework to perform continuous delivery and accelerate innovation. In this video, I’ll give you a peek into some of the work we at Labs are undertaking to accelerate application development. Specifically, I’ll walk you through the steps to create a deployment pipeline in Jenkins using the JBoss TicketMonster...

One of the greatest advantages of using docker containers is the fact that you can move them between environments. A promotion from Development to a Production environment, shouldn’t take more than some few seconds. This is one aspect of “Continuous Delivery” Because Microservices Architectures are “independently replaceable and upgradeable”, they are the best scenario to show a “Deployment Pipeline”. Red Hat Developers has produced a sample and free application called “Red Hat Helloworlds MSA” that demonstrates different aspects of microservices...

Prior to working at Red Hat, I worked for a software company, building financial software for large institutions. From my experiences I knew that some customers required, or demanded, a very aggressive Service Level Agreement (SLA). If we consider an SLA of 99.999% (generally referred to as “five nines”) then this would allow for a six-second unavailability or downtime over a full week, anything more and penalties would have to be paid. To provide this level of uptime, it is...

JBoss Enterprise Application Server 7 has been out since June, and if you build and deliver using a Java EE environment and haven’t yet upgraded to EAP7, it’s time to make the jump. Here’s a look at what’s new in JBoss EAP 7, what has changed since JBoss EAP 6, and how to get the most out of JBoss EAP 7 as your Java EE7 server. Overview JBoss EAP 7 is bassed on WildFly Application Server 10, which provides a...

Do you like JavaEE apps, but wonder how to fit them into a microservices-centric workflow? WildFly Swarm is the answer. I know—“Java” and “microservices” are not words that seem to go together. Java is an old, relatively unsexy programming language. It’s a pretty useful one, but it was created long before the era of Continuous Delivery, containers and microservices. But that doesn’t mean you have to give up on Java if you want to take advantage of microservices. WildFly Swarm...

Recently, I was searching for a solution to configure the security domain of Red Hat JBoss Enterprise Application Platform with the local operating system based user registry so that the application could directly authenticate its users with local operating system users. I understood that it would be difficult to implement a generic solution, as authentication mechanisms are strikingly different between Windows and Unix/Linux. After checking several blogs and forums, I decided to implement this using JPAM for Unix/Linux and Waffle...

Keen to build web applications for the cloud? Get a quick hands-on introduction to OpenShift®, the open source Platform as a Service (PaaS) offering from Red Hat®. With this practical guide, you’ll learn the steps necessary to build, deploy, and host a complete real-world application on OpenShift without having to slog through long, detailed explanations of the technologies involved.

In an earlier article, Debugging Java Applications using the Red Hat Container Development Kit, it was discussed how developer productivity could be improved through the use of remotely debugging containerized Java applications running in OpenShift and the Red Hat Container Development Kit. Not only does remote debugging provide real time insight into the operation and performance of an application, but reduces the cycle time a developer may face as they are working through a solution. Included in the discussion were...

Red Hat JBoss Resource Planner (part of Red Hat JBoss BRMS, the enterprise product based on the upstream OptaPlanner community project) is the leading open source constraint satisfaction solver. A constraint satisfaction solver is a solving engine build around sophisticated optimization algorithms that allows to plan for optimal use of a limited set of constrained resources. Every organization faces scheduling problems: assign a limited set of resources, for example employees, assets, time and money, to build products or provide services...

In this series of article, I will present several ways to deploy an application on an EAP Domain. T he series consists of four parts. Each one will be a standalone article, but the series as a whole will present a range of useful topics for working with JBoss EAP. Part 1: Set up a simple EAP 7.0 Domain (this article). Part 2: Domain deployments through the new EAP 7.0 Management Console Part 3: Introduction to DMR ( Dynamic Model...

JBoss BRMS provides a sophisticated and powerful business rules engine. The BRMS rules engine allows an organization, among other things, to: define rules in single, governed, environment. define rules in the domain language (or syntax) of the problem domain. declaratively define rules. It allows to define what to do, not how to do it individually test rules, outside of any application logic. (incrementally) update rules without the need to update and/or restart the application that uses the rules. have better...
