A key component to a successful migration is a “migration mission statement.” The migration mission statement’s purpose is to summarize the key parts of a migration into a succinct, simply-communicated format that results in a clearly defined migration goal that is easily measurable for success. A sample migration mission statement could be:
Migrate the Acme Order Processing java application from the current proprietary IBM hardware running AIX and WebSphere into a cloud infrastructure running Red Hat Enterprise Linux and JBoss Application Server; in order to provide better TCO and ROI, as well as provide increased scalability and reliability. The migration should be performed during non-peak hours, have minimal downtime requirements, and provide for rollback if necessary.
Generally speaking, there are several factors that go into planning and executing a successful migration project. But by answering the following questions, a significant amount of the information necessary for a successful migration can be gathered.
The most basic question to initially ask is simply, “What is being migrated?” This simple question sets the stage for gathering the additional information that is required. Is the migration moving all services from one server to another? Maybe it is migrating an application from one application server to another, or migrating storage from one array to another. Each of these scenarios are going to have unique data-gathering requirements that need to be understood in order to successfully plan and ultimately execute a successful migration.

Cloud computing represents a major shift in enterprise IT architecture that requires companies to rethink their strategy. Red Hat is bringing to market a full portfolio of training and certification offerings that enable customers to evaluate Red Hat’s cloud technologies and understand how to deploy them successfully.
Customers seeking to build an open Infrastructure-as-a-Service (IaaS) cloud may look to Red Hat OpenStack as their foundation. OpenStack is emerging as a leading platform for IaaS cloud architectures and has attained broad industry support. Red Hat is excited to announce the immediate availability of Red Hat OpenStack Administration (CL210), which provides architects and system administrators with a hands-on course to learn how to install, configure, and manage a Red Hat OpenStack deployment. Later this summer Red Hat will also introduce the Red Hat certificate of expertise in OpenStack IaaS, which will validate a professional’s ability to successfully deploy and administrate an OpenStack based IaaS cloud.
For customers looking to deliver an open Platform-as-a-Service (PaaS) cloud, OpenShift Enterprise by Red Hat may be the solution. OpenShift gives application developers self-service access so they can easily deploy applications on demand. Red Hat is pleased to announce the immediate availability of OpenShift Enterprise Administration (CL280), a heavily lab-based 2-day course that guides the student through the steps to install, configure and manage an OpenShift based PaaS cloud.

Sean Millichamp was crowned worldwide Red Hat Certified Professional of the Year in June 2012 at Red Hat Summit. With Rafael Guimaraes officially set to be the next recipient of the award at next week’s Summit event in Boston, Sean offers us a look back at his past 12 months since winning the esteemed title.
It’s been a little over a year now since Red Hat selected me as the 2012 Worldwide Red Hat Certified Professional of the Year and what a year it has been! The whole experience was (and continues to be) amazing.
Initially, I didn’t tell too many people when Red Hat notified me that I had won. As with any contest there is some requisite legal paperwork (permission to use your name, etc.) that has to be cleared and so I only told my family, my boss, and a couple of other co-workers who knew I had submitted an entry, but that didn’t last long. The news passed quickly from my boss, to the company VP, to the CEO and then to the entire executive and sales teams. I still had not announced it to my surrounding coworkers but when a fairly continuous stream of people began walking up to me to shake my hand I found myself repeatedly explaining to those around me why I was being congratulated and what the award was – all the while caught somewhere between my more typically modest self and extreme bubbling pride.
In fact, I think my employer, Secure-24, was every bit as excited about this award as I was. If this seems unusual you need only to understand our business. We are a managed hosting company: IT is our business. The majority of our employees are either technical or work to directly support technical resources. So, when a senior engineer on one of their main product platforms wins a top award with a key partner – it was a sales/marketing dream come true. Our marketing team even issued a press release about it!

Replicated Red Hat Storage Server Volumes provide you with high-availability, when a single server goes down all your data is still there. Even better, if you were using that server to access your data using the native client it will automatically switch over to a server that is still responding. But what if you want to mount the volume while the server you normally use is down?
When you want to mount a Red Hat Storage Server Volume from your /etc/fstab you normally use a line like this:

The demand for Linux engineers today is growing rapidly with the increase of “cloud” services. More and more organizations want their data to be available everywhere they go with zero downtime to their applications. This kind of demand from organizations requires that engineers know their “stuff” cold. When a web server goes down or a disk fails, you don’t have time to Google for an answer while there is a service outage affecting all of your customers. Becoming Red Hat certified is just one way to set yourself apart when showing potential, or current, employers that you can rise to the challenge.
Red Hat has clearly recognized these types of challenges that engineers and administrators face today when they developed their exams. Instead of the normal Q & A you would expect, these exams are fully hands-on. This lab style exam format helps to set Red Hat apart from other vendors by showing that certified individuals are highly experienced in their roles. For me, having Linux experience is critical to my job and being certified (from multiple vendors) shows expertise to my clients and peers.
The two main Red Hat exams are the Red Hat Certified System Administrator (RHCSA) exam, and the Red Hat Certified Engineer (RHCE) exam. As previously mentioned, each exam is completely hands-on and requires a solid proficiency of Red Hat Enterprise Linux in order to pass. The RHCSA is two and half (2.5) hours long, while the RHCE is two (2) hours.

OpenShift is great! Developers can quickly start development on a new project. Just log into the web console, create a new application, select a gear and start coding. When you are done implementing a feature you push to OpenShift and after a few seconds you can admire and share your work with the whole world.
But there is more to consider when working with OpenShift. What if you develop in teams? Usually applications are not directly deployed into production. How can I implement a staging process harnessing the OpenShift Infrastructure? How do I know if my changes passed an Acceptance Test or failed it? How does a test team know which features have been implemented?
The answer to these questions are usually not easy, and every company has implemented their own set of processes to address these problems. Although some Organizations have automated some of their IT Infrastructure, there are still a lot of manual processes and changes involved when it comes down to taking a particular software release from development into production. On the other hand, the business stakeholders have a high interest into a fast and efficient Release process, because every day that my feature is not in production and available to my users, is lowering my ROI.

Long an acquaintance and ally of government institutions, open source is no longer considered rocket science by the enterprise.
Companies find open source attractive because they’re not tied to one vendor, can make improvements in the system at any time and realize cost savings, all helping boost market penetration. And, of course, there’s the benefit of communities continuously improving the products.
In the outside world, governments are strong sponsors of this type of initiative, especially in Brazil, where the use of free and open source software is encouraged to make the market more democratic. And, of course, the market has become increasingly more open to open source. While there were once concerns about the reliability, security, and functionality, those fears are all gone. Red Hat has made it possible to combine the benefits of these technologies with the necessary support for mission-critical environments, developing platforms and the specific demands organizations face.
