Weekly Recap – Cloud Computing, SDN, DevOps, and More

Here’s some of the news we came across that interested us this week

The Open DayLight Project – A pretty big development for Software-Defined Networking:

"This is about code at the infrastructure level to help shape the future of SDN and every major player is in. This diversity is an early sign of a healthy community and the size and expertise of these companies demonstrate industry-scale support." (by Jim Zemlin)


An interesting article about “household name cloud computing companies” adopting a new, more efficient method of cooling their servers:

"In an un-air-conditioned shed in a location Price will not disclose, alongside bags of salt used to run a water softening system, sit waist-high tanks full of mineral oil. In their depths are tiny lights blinking like bioluminescent creatures from the abyss, and something even more unexpected: row after row of PC motherboards, craggy with RAM and CPUs and hard drives and cables." (by Christopher Mims)


Why software-defined data centers cost much more without optimized power and cooling (pretty relevant to the link above!):

"To really conquer the challenges of reliability and optimization of resources, you have to add software-defined power and cooling to the mix. Without these capabilities...your software-defined data center has a good chance of running into any number of brick walls." (by Dan Woods)


Why companies can fall short of continuous delivery when implementing DevOps:

“Continuous delivery is often looked at as the goal of DevOps, but Ovum does not agree with this view, primarily because DevOps is a goal in itself.“ (by Chandranshu Singh)


A well-written piece on why software configuration management is necessary:

"Configuration management (CM) is actually kind of a big thing, not just for software but for hardware and other IT-related “stuff” like servers, desktop computers, routers, storage, and the like." (by Mary Lotz)


One author’s experience from Devopsdays London, PLUS a nerdy video!



A good tutorial on using Chef:
