Taste of Training Preview: EAP6 clustering over TCP

by Will Dinyes (Red Hat)

With the recent release of JBoss Enterprise Application Platform (EAP) 6, Red Hat is ensuring that developers and administrators alike are getting more for less. More performance, for less memory. More services, with less configuration. And more management tools, with less hassles. In conjunction, the Red Hat Training team has been hard at work integrating more into our JBoss courses. First, we updated our popular JBoss Application Administration I course (JB248). Now we are set to release our updated course JBoss Application Adminisration II (JB348). Available in December, JBoss Application Administration II will bring all of the advanced topics we covered in our similar course for EAP 5, such as clustering, performance tuning, and JBoss Operations Network, and will add even more content specific to EAP 6, covering CLI scripting, messaging providers, and an introduction to OpenShift.

Business value of open source software

by Satish Irrinki (Red Hat)

It’s a truism that adopting open source software (OSS) reduces costs, but that’s not all. Let’s make a deeper dive into the business value of adopting OSS and uncover how the adoption provides immense value at multiple levels of an organization. The value proposition for OSS can be attributed to three groups within an organization – Technical Buyers, Business Buyers, and Economic Buyers.

Technical Buyers
Technical buyers can be best described as the line managers who are operating under stringent budgets to do more with fewer resources. As a result they aim to reduce costs and increase efficiencies within their operating units. In a bid to increase their resources utilizations, the technical buyers seek to increase reliability and flexibility in their operations. To achieve these goals they use systems that are reliable, adhere to standard specifications, and low in cost.

The high level of collaboration and contribution within the OSS development model accelerates the number of features that typical open source software provides. Availability of source code allows the adopters to make custom changes and tailor the software for specific needs. The ability to reuse software components across the organization (develop once and use within multiple systems) reduces the unit cost of development. These virtues of OSS mesh well with the goals of technical buyers and make OSS a viable option when making technology decisions.

Guest post: My journey to RHCA

The following post was authored by Pete Durst, instructor and director of technology at ExitCertified, a Red Hat Training partner with locations throughout the United States and Canada. Delivering training since 1991, Pete was named Red Hat FY12 architect-level instructor of the year for North America, and recently became a Red Hat Certified Architect, the highest level of certification for Red Hat Enterprise Linux. The thoughts and opinions expressed here are Pete’s.

Many years ago, when I first became aware of the different Red Hat certifications, I thought nothing of what it meant to be an RHCT or RHCE. These appeared to be similar to other vendor’s certifications, like Sun’s SCSA and SCNA, and had similar value to me. Upon further investigation, it became apparent that while those certifications were gained through online testing methods that used multiple-choice questions and fill-in-the-blank essays, Red Hat used hands on, practical testing. It’s one thing to say that you know how to do something and it’s another to prove that you know how to use it, by actually setting up a server and making it perform as expected.

Tips & Tricks: JB348 Application Administration II

by Bruce Wolfe (Red Hat)

Furtureproof Installation

When planning your installation of JBoss EAP 6, you have three choices; ZIP, JAR or RPM. The JAR based installer is, arguably, the best and most flexible option because it will generate an answer file that can be used for silent, repeatable installs; great if you have to install JBoss on multiple servers (e.g. clustering). Using the answer file, repeat the install with:

$ java -jar jboss-eap-installer-<version>.jar <answer_file>.xml

Keep Calm and Innersource On

by Guy Martin (Red Hat)

“Open source is scary!”

“How can something ‘open’ be secure?”

“Won’t using open source in my products mean I have to give away my IP?”

These are all examples from real-world conversations with both external and internal stakeholders during my career as a developer and consultant.  There are many more such examples, which I previously built into a blog titled Top 10 Signs Your Enterprise Doesn’t ‘Get’ Open Source.  The good news is that with the emergence of Linux, Apache, JBoss and other important open source technologies, we don’t hear these kinds of things as often.  The bad news is, there are still quite a few industries and companies where these fears are the norm.

How to convert a JBoss Developer Studio web project to a Maven project (JB225)

by Jim Rigsbee (Red Hat)

In this article, we will convert a web project generated by the JBoss Developer Studio CDI Web Project wizard to a Maven project. Doing so will give you the power of the Maven build system with its dependency management, build life cycles, and automated JEE packaging abilities. Follow these steps:

a. Right click on the project name in the Project Explorer tree and select Configure → Convert to Maven Project… In the wizard steps be sure to select WAR packaging.

BPM: Utilizing JBoss technologies to increase business performance and agility

by Duncan Doyle

With the growing popularity of cloud environments and cloud-like architectures, the Service Oriented Architecture (SOA) paradigm has become increasingly important. Having been the previous big buzzword in IT, the term SOA has often been used as a means to sell software products instead of a term to refer to architectural style. However, in order to benefit most from the new possibilities in virtualization, just-in-time provisioning and on-demand scalability it has become a must for businesses to partition their enterprise logic and functionality into individual components which can independently be deployed in heterogeneous environments.

One of the goals of an SOA is to provide the enterprise with a set of re-usable, readily available business services, and as such reduce cost and provide greater operational agility. The autonomous nature of well-defined services make these components the perfect candidate for deployment in cloud environments. These individual services can then be combined, or composed into business applications which provide the actual business value. The specific compositions of these services in fact defines the actual business process.

Guest Post: Bruno Lima, Red Hat Certified Professional of the Year, EMEA

by Bruno Lima

Becoming EMEA’s Red Hat Certified Professional of the Year was very easy. I just wrote a letter and crossed my fingers, haha. Jokes aside, I believe I became a Red Hat Certified Professional of the Year because when I entered my submission, I not only wrote a reply, I relayed how Red Hat is integral to both the story of my life and in my career. From the innovative projects I’ve participated in to the satisfaction of our customers, Red Hat has meant a lot to me.

I started using Red Hat technologies in the mid-90s when open source was still unknown by many and ignored by almost everyone. I remember my first installation of Red Hat, which was at a public company in a small town called Sao Luis in Brazil. It was where I was born and raised. The company needed a reliable solution to run an electronic mail system, and at that moment the only platform that met our needs was to use the Red Hat Linux with Sendmail. I never stopped using Red Hat technologies after that, using Red Hat and open source for more and more projects.
