Gradual enterprise adoption of SDN will drive a $12.7 billion market by 2020, TBR says.
Cloud and big data technologies complement machine learning, creating an array of new applications.
Our Data Center optimization journey has finished. We virtualized the workload, got rid of legacy technologies, reduced the number of server uplinks, replaced storage arrays with distributed file system and replaced physical firewalls and load balancers with virtual appliances.
Let’s see what’s left: it turns out you really don’t need more than two switches in most data centers.
I like listening to video training on my smartphone while walking to work. To save the space on the memory card I convert videos to MP3 audio in advance. For this purpose I wrote a Bash script video_to_mp3.sh which helps me to manage a conversion job. The script uses ffmpeg for conversion and it creates parallel conversion tasks to speed up the conversion process. The script checks the CPU load and it creates a new background process only if the CPU load is under a particular limit entered by a user.

Below is the output from the conversion process.

The script creates a log file displaying info about the result of all conversion tasks. If the conversion fails for a particular video file, the script displays a return value of ffmpeg utility and the name of the file which is not successfully converted.

It’s October in the UK and blimey charlie, it’s a bit chilly. Good news then that the OpenStack Summit is in Barcelona! In comparison to Canada or Japan, it’s on my doorstep! Spain being the home of English holiday makers, the smell of sun cream, sangria and chicken nugget dinners awaits.
It Felt Different
Needless to say, I play investigator at these summits. Whether it’s the SDN congress, OpenStack or other networking events, the cynical grump hat is donned. Before I even managed to investigate anything, I felt something different. The hype lever was set to average and this show felt almost corporate. Good news or bad news? Something I’ve struggled to quantify all week and even now as I sit on the home bound flight to Blighty, I continue to ponder.
Big bang news was lacking like previous shows. Realistic use cases, real commentary and on-stage demos made this feel different. One of the demos made me both cringe and chuckle as Mark Collier played real life chaos monkey, pulling fibres and eventually even cutting through them during an EPC demo which included OPNFV Doctor and Vitrage. This demoed OpenStack’s capability to integrate with monitoring and life cycle tooling. Continue reading
Q3 revenues grew, and losses could have been worse.
