| Figure 1: Visibility and the software defined data center |
While I genuinely believe that the network will play an immensely strategic role in the microservices world, inspecting and storing billions of API calls on a daily basis will require significant computing and storage resources. In addition, deep packet inspection could be challenging at line rates; so, sampling, at the expense of full visibility, might be an alternative. Finally, network traffic analysis must be combined with service-level telemetry data (that we already collect today) in order to get a comprehensive and in-depth picture of the distributed application.Sampling isn't just an alternative, sampling is the key to making large scale microservice visibility a reality. Shrink ray describes how sampling acts as a scaling function, reducing the task of monitoring large scale microservice infrastructure from an intractable measurement and big data problem to a lightweight real-time data center wide visibility solution for monitoring, managing, Continue reading
Speaking of CLI
When someone starts complaining about networking device CLI, remind him that other parts of IT aren’t doing much better. For example, it’s oh-so-easy to install a package on Linux or OSX.
Auditing network configurations with Nelkit
Even if you have tools in place to automate your network configuration, there’s a good chance that someone has made some manual changes. Perhaps some of your routers were overlooked the last time you send out that access-list, or a new site has been deployed using an old template. In those situations you want to audit the configuration of your network devices. Network configuration audit is one of the features of Nelkit.

SDxCentral Weekly News Roundup — March 11, 2016
Here’s a roundup of the week’s news related to software defined networking (SDN) and network functions virtualization (NFV) and the rest of the SDxCentral universe, starting with a few tidbits from the OCP U.S. Summit: Radisys joined the Open Compute Project (OCP) as a silver member and launched DCEngine, an OCP-based design for hyperscale data center...

Wireless Gets Serious
Drew Lentz, chair of Interop's Wireless & Mobility Track, discusses the increasing demands placed on networks as the type of clients, number of clients, and functionality changes. He explains how pressures from the Internet of Things, location-based services, and expansive campus networks are prompting new investments in wireless networks and requiring careful consideration.

No, you backoff on backdoors or else
Speaking at #SXSW, President Obama threatened the tech community, telling us to backdoor our encryption ourselves or else congress will mandate a worse solution later.No, Mr. President, it works the other way around. You'd better backoff on your encryption demands, or else the tech community will revolt, That's what's already happen with Apple's encryption efforts, as well as app developers like Signal and Wickr. Every time you turn the screws, we techies increase the encryption.
It's not a battle you can win without going full police-state. Sure, you can force Apple to backdoor its stuff, but then what about the encrypted apps? You'd have to lock them down as well. But what about encrypted apps developed in foreign countries? What about software I write myself? You aren't going to solve the "going dark" problem until you control all crypto.
If you succeed in achieving your nightmare Orwellian scenario, I promise you this: I'll emigrate to an extradition-free country, to continue the fight against the American government.
Your crypto backdoors creates a police-state beyond what even police-state advocates like Michael Hayden and Linsdey Graham can tolerate. Your point on "balance" is a lie. We've become radically unbalanced toward mass Continue reading
