Increasingly in today’s world, data centers are moving towards software-defined computing, networking, and storage. IT infrastructure that supports the application and data workloads is moving from bare metal servers to cloud. While the most obvious justification for this shift can be summarized as increased efficiency, capacity utilization, and flexibility (to scale up or down), there are less obvious fundamental economic and financial principles in play that contribute to overall business stability of the organizations and lines of business (LOB).
Cloud computing has changed the cost structure of IT infrastructure. Historically, IT infrastructure was considered a capital expenditure (CapEx) that requires large upfront investments leading to higher fixed costs for the business. With the advent of cloud computing, primarily because of its pay-for-use billing model, IT expenditure shifted from fixed operating cost structure to variable operating cost (OpEx) model.
This shift not only decreases the need for larger cash flow requirements or, in lieu, higher liabilities on balance sheet (akin to capitalization of lease expenses) for the CapEx, it also reduces the volatility in the operating income for the business.

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.

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!

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.

The following article originally appeared here in the UK and here in Germany.
Who could have predicted the impact on mainstream businesses of data coming in via social media and mobile technology, the escalating importance of trends such as ‘big data’ or the move towards cloud computing that is now gathering momentum?
The sources of data coming into the enterprise IT infrastructure are proliferating, with new channels and touch-points constantly emerging at an unprecedented rate. Clearly, in an uncertain world, flexibility is a critical component of any business IT strategy.
With today’s customers choosing to interact through multiple channels, businesses are wasting time and budget ‘hand-carrying’ information from application to application, frequently without adding value at best and introducing human error at worst.

Like many organizations, Red Hat Consulting constantly seeks ways to eliminate organizational inefficiencies in our business operations. These inefficiencies typically deal with how our consultants are trained on cutting edge technologies, how our sales force demonstrates product capabilities to our customers and prospects, and how our technical groups request operational environments (virtual machines, platforms, etc.)
To attack this problem, a team of architects and consultants set out to design, implement, and operationalize a system that will reduce these inefficiencies. This system is called the Red Hat Innovation Center (RHIC). Its vision is twofold:
1. To demonstrate Red Hat products’ features and capabilities through a solutions-oriented approach based on real world use cases.
2. To enable our consultants to quickly and efficiently learn our technologies by lowering the barriers to entry to internal training.

The holiday decorations are now (hopefully) put away, and fond memories of merriment from the past month or so are behind us. All that remains now is the time-honored tradition of the New Year’s Resolution. This should not surprise most of you, but the perennial favorite is usually a combination of ‘lose weight, eat healthier, get in better shape.’ Pondering my own resolutions to continue on a healthier path got me thinking about what it means to get your company in ‘Open Source Shape.’
There are many parallels to successfully getting yourself in better physical shape and getting your company started on the right foot to more successful and productive use of open source. Let’s take a look at a few of these examples below, pulling some lessons from the exercise world that you can apply in your enterprise.
