OpenDaylight is an active community of developers who are passionate about transforming networking. This blog series highlights the people who are collaborating to create the future of SDN and NFV.
David Goldberg is ConteXtream’s lead software engineer and was the first software developer to join the next generation SDN product team. David is also leading ConteXtream’s contribution to the OpenDaylight project and is one of the top commiters to the LISP Flow Mapping project. Prior to Contextream, David was responsible for the development of network analysis tools during his army service in an elite technological group in the IDF Intelligence Corps. David holds a BA in Computer Science and Management (cum laude).
How did you get involved with OpenDaylight?
I got involved with OpenDaylight when ConteXtream decided to base its next generation SDN on open standards and open source emerging in the field. We at ConteXtream believe that an open source and open standards approach to SDN and NFV is the way to achieve a scalable and programmable infrastructure that operators are looking for. This will ensure standardization through a common infrastructure that everyone will use. The advantage of OpenDaylight as an open source project is that everyone can join and help develop the controller. There is no doubt that it will become the best SDN controller in the market. We joined the OpenDaylight project to help create the foundation for our second generation carrier-SDN solution.
Currently, there are many trends in HPC clustering that include software complexity, cluster growth and scalability, system heterogeneity, Cloud computing, as well as the introduction of Hadoop services. Without a cogent strategy to address these issues, system managers and administrators can expect less-than-ideal performance and utilization. There are many component tools and best practices to be found throughout the industry. To help our audience build and manage successful HPC Clusters the editors of insideHPC have created this article series called “the Five Essential Strategies for Successful HPC Clusters.”
When it comes to managing infrastructure deployments of a certain size, even a ninja sysadmin can’t do it all without some help. In fact, one might argue that knowing when and how to use IT automation tools for managing infrastructure is a prerequisite to getting your admin blackbelt. Enter Puppet.
Difio is a Django based application that keeps track of packages and tells you when they change. It provides multiple change analytics so you can make an informed decision on when or what to upgrade. Difio was created as closed software, then I decided to migrate it to open source to allow for in-house deployments and attract a larger community around the project.
The world’s largest PC maker is announcing its first mainstream Chromebooks today, making the company the latest in a long list of Windows manufacturers to hop on board Google’s stripped-down operating system. Lenovo is unveiling two Chromebooks today, the N20 and N20p. Both models are identical save a 300-degree rotating touchscreen on the N20p that lets you use it in a more comfortable touch-only mode. Unfortunately, Chrome OS largely remains ill-suited to touch, but it should be an appealing option for some. In terms of hardware, that’s the only big surprise here. The Chromebooks are fitted with 11.6-inch, 1366 x 768 screens, Haswell-based Intel Celeron processors, 2GB of RAM, and 16GB of storage — all of which are fairly standard….
