Cisco’s Big Data Analytics Vision: Some Data Will Be Distributed Forever

By Shamus McGillicuddy on Jun 12, 2015 12:26:17 PM

Champions of big data analytics extoll the virtues of massive data stores. Enterprises have so much unstructured data that could help them improve operations and generate new revenue, they say. The more bytes, the better. Some might assume that enterprises will simply push every byte they can find into a Hadoop cluster or data warehouse. [...]

Open network management is the focus on spring ONUG meeting

By Shamus McGillicuddy on May 21, 2015 1:19:20 PM

The Open Networking User Group (ONUG) is a community of IT executives that are using their combined buying power to influence the networking industry. Members hail from companies such as Bank of America, JPMorgan Chase and Fidelity Investments. ONUG’s goal is to specify requirements and reference architectures for products that are open, more affordable and more agile than what vendors traditionally offer.

Over its first two years of existence, ONUG has focused on software-defined WAN (SDWAN), network virtualization overlays and network service virtualization (also known as network functions virtualization or NFV).  Last week, ONUG convened its spring meeting at Columbia University, where its focus expanded into network management and operations. ONUG introduced three new working groups that will specify open networking requirements and begin testing vendor solutions in various management areas.

SDN and Network Management at ONUG

By Shamus McGillicuddy on May 12, 2015 9:13:36 AM

As an analyst who focuses on network management research, I am particularly intrigued by software-defined networking (SDN). As SDN architectures are deployed in data centers, local area networks and WANs, network management practices will have to evolve. For instance, SDN may make it easier for cloud administrators to provision network services and connectivity for a new application, but how do you ensure that your new programmable network remains compliant with configuration controls and policies? Is your performance management tool able to model and monitor an SDN controller? If you have traditionally relied about appliance-based load balancers and firewalls in your data center, how do you monitor and manage those network functions when they become virtualized services that are as mobile and dynamic as the workloads they serve?

The State of the Software Defined Data Center

By Torsten Volk on Feb 3, 2014 11:15:45 AM

Of course, I always encourage practitioners to carefully study the full EMA research report on the “Obstacles and Priorities on the Journey to the Software-Defined Data Center” or at least read the research study summary or at the very least join the EMA SDDC Research webinar on February 18, but I still want to briefly summarize the key findings here.
