Several of my recent blog posts have described materials aimed at the latest Linux+/LPIC-1 exams; here I do likewise for the latest and greatest versions of the Red Hat Enterprise Linux 7 exams for the Red Hat Certified Engineer (RHCE) and Red Hat Certified System Administrator (RHCSA) credentials.
Yes, although Software Defined Networking (SDN) and Network Functions Virtualization (NFV) have been out and about in the technology space for more than three years now, and plenty of major players offer interesting products and services in this vein, I'm still seeing enough of a gap between technology makers and service providers hawking these wares, and companies taking up such offers, to provide continuing ground for concern. This goes double for basic training and certification on SDN and NFV, where the number of options and offerings come nowhere near the number of players jockeying for advantage on this playing field.

Hadoop is an Apache project, which means it's open source in nature. It's also a popular framework based on Java that's designed to support distributed storage, especially in connection with distributed processing of humongous data sets on generic computing clusters. As such, it's also an important element in many Big Data projects and activities. Given how popular Big Data is nowadays, no big stretch is needed to see Hadoop in the same light.

Over the years, it's been interesting to watch the Cisco Learning Center grow and evolve to better meet the needs of IT professionals pursuing that company's often-coveted certification credentials. Of all the many things that Cisco does right with its cert programs, the company's "Study/Learn Master List" is second to none when it comes to helping interested parties find their way to the right exams, objectives, training, and study/prep materials. If you don't know about this already, you should; if you do know about it, you might want to head back to give it another look, as numerous exams have been (or will be) updated or replaced in the very near future.
Long a leader in cloud technologies and related service offerings, Amazon offers a substantial and growing certification program to support its Amazon Web Services (AWS) offerings. Currently, credentials are available for architects, developers and sysadmins at associate and professional levels, with more on the way.
In mid-September, IBM sent an interesting but also threatening e-mail to a number of employees in its Global Technology Services division, the arm of the company responsible for providing consulting and technology services to its biggest and most important customers. Observing that its recipients "have not kept pace with acquiring the skills and expertise needed to address changing client needs, technology and market requirements," those same recipients were ordered into a one-day-a-week training program for 23 weeks (almost half a year). During that training interval, their pay would also be docked by 10 percent, perhaps splitting the difference with those employees of the 20 percent loss in productivity that would therefore ensue. What does this decision have to tell us, and those currently playing the IT game as professionals?
As seems to be case with many cert sponsors nowadays, ISACA used to stand for the Information Systems Audit and Control Association, but later changed its official name to match that acronym rather than sticking to the expanded version. ISACA remains an organization devoted to IT systems audit and governance training and certification, however, and its Certified Risk and Information Systems Control (CRISC) credential is becoming a high-value element in the audit and control realm for IT. Just recently, ISACA let current and prospective members of the association know that change is coming to the CRISC in 2015.
