Networking blogs: Troubleshoot with ClearSight Analyzer; DevOps demand

Bloggers explain how to use the ClearSight Analyzer to monitor packets and assuage network engineers' concerns about the growing demand in DevOps.

Tips for troubleshooting without packet capture

Troubleshooting FTP errors typically means capturing packets in order to analyze them or retrieve them later, but that's not always necessary when you don't need to save frames for further inspection. Tony Fortunato from the Technology Firm offers some tips for using the "Monitor Mode" of Fluke Networks' ClearSight protocol analyzer. In this mode, the analyzer monitors all incoming and outgoing traffic and provides a summary of the information from Layer 2 through Layer 7.

Check out Fortunato's quick video rundown of the ClearSight Analyzer and how to diagnose a failed FTP session without capturing a single frame.

The case for integrated computing platforms

The conversation around IT infrastructure is taking leave of the technical and settling into a more business-oriented area of focus, according to ESG Senior Analyst Mark Bowker. In a discussion on how integrated computing platforms are changing companies' IT consumption models, he predicts that the next phase of server virtualization will move beyond the talking points of cost containment and resource consolidation to highlight maximized operational benefits. IT organizations won't have much choice but to embrace more automated environments and on-premises cloud computing models.

A perspective on network virtualization

Network virtualization is truly possible, Jason Edelman insists in his recent post exploring the topic. That means overlays shouldn't have to be tied to hardware, and virtual LANs aren't used for virtual workloads. He explains why there needs to be some exchange between physical and virtual networks, why the administrators of virtual servers don't need to be the ones operating and managing the virtual network, and why end users matter as the real consumers of the technology. Overlays are the next logical step in the evolution of network virtualization -- a process Edelman says has been all but stagnant for the last decade.

DevOps programmers in demand, but experts still needed

In the well-served market of data center switching, customer expectations around workflow integration have boosted emphasis on the DevOps movement. Mike Bushong, vice president of software-defined networking startup Plexxi, says this shifting focus will lead to the rise of new positions in IT for programmers who are skilled in developing connective software. Fitting individual components together requires the overarching perspective of a skilled architect dedicated to the issue, and will put DevOps people in high demand. But despite what the foreboding headlines indicate, the growth of DevOps will not make network engineers obsolete. Experts in networking will continue to have an important place in solving network problems, though the growth in the field may slow as DevOps continues to expand.

See why demands on IT are far from slowing in Bushong's blog post.
