The Cost of Networking Has Not Declined

One of the common taglines parroted by SDN aficionados goes along the lines of “The cost to acquire and manage server and storage architectures has declined over time while networking stays stubbornly expensive.” (I took it straight from an anonymous blog comment).

Let’s see how well it matches reality.

Oracle is gunning for AWS with new infrastructure offering

Larry Ellison has a message for Amazon Web Services: Oracle is going to give Amazon a run for its money in the cloud market."Amazon's lead is over," he said during his keynote address at the OpenWorld conference in San Francisco. "Amazon's going to have serious competition going forward."To that end, the company he co-founded is launching a set of new cloud datacenters that are aimed at providing more powerful compute instances to help it compete against the likes of AWS, Azure and other cloud players. The generation 2 datacenters will be capable of bringing a variety of performance improvements to customers who want to run high-performance workloads in the cloud.To read this article in full or to leave a comment, please click here

Intel’s new PC, IoT chief brings fresh ideas to the veteran chip maker

Intel is now more than just a PC company. At industry events, the company's keynotes feature drones flying around, robots walking on stage and musicians creating tunes from wearables. The chip maker is helping BMW build an autonomous car, will sell modems to Apple, and is leading the development of next-generation 5G cellular networks. For all these new markets, it will provide chip and data-center technologies. The transformation is happening partly under the leadership of Venkata Renduchintala, president of the Client and Internet of Things (IoT) Businesses and Systems Architecture Group at Intel. As Intel's second-in-command, he helped cut struggling products like mobile CPUs and sharpened the company's focus on IoT, servers, and connectivity.To read this article in full or to leave a comment, please click here

Why Snowden won’t be pardoned

Edward Snowden (NSA leakerblower) won’t be pardoned. I’m not arguing that he shouldn’t be pardoned, but that he won’t be pardoned. The chances are near zero, and the pro-pardon crowd doesn't seem to be doing anything to cange this. This post lists a bunch of reasons why. If your goal is to get him pardoned, these are the sorts of things you’ll have to overcome.

The tl;dr list is this:

• Obama hates whistleblowers
• Obama loves the NSA
• A pardon would be betrayal
• Snowden leaked because he was disgruntled, not because he was a man of conscience (***)
• Snowden hasn’t yet been convicted
• Snowden leaked too much
• Snowden helped Russian intelligence
• Nothing was found to be illegal or unconstitutional

Obama hates whistleblowers

Obama campaigned promising to be the most transparent president in history. Among his campaign promises are:

Protect Whistleblowers: Often the best source of information about waste, fraud, and abuse in government is an existing government employee committed to public integrity and willing to speak out. Such acts of courage and patriotism, which can sometimes save lives and often save taxpayer dollars, should be encouraged rather than stifled as they have been during the Bush administration. We need to empower Continue reading

Salesforce is betting its Einstein AI will make CRM better

If there was any doubt that AI has officially arrived in the world of enterprise software, Salesforce just put it to rest. The CRM giant on Sunday announced Einstein, a set of artificial intelligence capabilities it says will help users of its platform serve their customers better.AI's potential to augment human capabilities has already been proven in multiple areas, but tapping it for a specific business purpose isn't always straightforward. "AI is out of reach for the vast majority of companies because it's really hard," John Ball, general manager for Salesforce Einstein, said in a press conference last week.To read this article in full or to leave a comment, please click here

Test-driving EVPN route publishing with GoBGP

In recent times there has been a lot of interest in tunnel based L2 networks, especially for Cloud Networks implemented with VXLAN.  The tunnel based networks were initially proposed with the idea of alleviating the 4k limit imposed with VLAN based networks. EVPN based VXLAN tunneled networks use BGP as control plane for L2 learning. … Continue reading Test-driving EVPN route publishing with GoBGP

Triggered remote packet capture using filtered ERSPAN

Packet brokers are typically deployed as a dedicated network connecting network taps and SPAN/mirror ports to packet analysis applications such as Wireshark, Snort, etc.

Traditional hierarchical network designs were relatively straightforward to monitor using a packet broker since traffic flowed through a small number of core switches and so a small number of taps provided network wide visibility. The move to leaf and spine fabric architectures eliminates the performance bottleneck of core switches to deliver low latency and high bandwidth connectivity to data center applications. However, traditional packet brokers are less attractive since spreading traffic across many links with equal cost multi-path (ECMP) routing means that many more links need to be monitored.

This article will explore how the remote Selective Spanning capability in Cumulus Linux 3.0 combined with industry standard sFlow telemetry embedded in commodity switch hardware provides a cost effective alternative to traditional packet brokers.

Cumulus Linux uses iptables rules to specify packet capture sessions. For example, the following rule forwards packets with source IP 20.0.1.0 and destination IP 20.0.1.2 to a packet analyzer on host 20.0.2.2:

-A FORWARD --in-interface swp+ -s 20.0.0.2 -d 20. Continue reading

Getting Started in the Mobile World

Got this challenge from one of my readers:

I've recently changed jobs and I am currently working for a telco. The problem is that I have no idea of what they are talking about when they mention SGSN, GGSN, Gi, Gn, etc... I only know routing and switching stuff :(.

Obviously he tried to search for information and failed.

Let’s Encrypt plugin for ASA

I wrote a certbot (Let's Encrypt ACME client) plugin for Cisco ASA. It runs on a separate box, talks ACME to the Let's Encrypt service and uses the ASA REST API to manage certificates on the ASA.

Review: “Snowden” (2016)

tldr:

• If you are partisan toward Snowden, you'll like the movie.
• If you know little about Snowden, it's probably too long/slow -- you'll be missing the subtext.
• If you are anti-Snowden, you'll hate it of course.

The movie wasn't bad. I was expecting some sort of over-dramatization, a sort of Bourne-style movie doing parkour through Hong Kong ghettos. Or, I expected a The Fifth Estate sort of movie that was based on the quirky character of Assange. But instead, the movie was just a slight dramatization of the events you (as a Snowden partisan) already know. Indeed, Snowden is a boring protagonist in the movie -- which makes the movie good. All the other characters in the movie are more interesting than the main character. Even the plot isn't all that interesting -- it's just a simple dramatization of what happens -- it's that slow build-up of tension toward the final reveal that keeps your attention.

In other words, it's clear that if you like Snowden, understand the subtext, you'll enjoy riding along on this slow buildup of tension.

Those opposed to Snowden, however, will of course gag on the one-side nature of the story. There's always two sides to Continue reading

Webcast: Hardening Microservices Security

Microservices is one of the buzz words of the moment. Beyond the buzz, microservices architecture offers a great opportunity for developers to rethink how they design, develop, and secure applications.

On Wednesday, September 21st, 2016 at 10am PT/1pm ET join SANS Technology Institute instructor and courseware author, David Holzer, as well as CloudFlare Solutions Engineer, Matthew Silverlock, as they discuss best practices for adopting and deploying microservices securely. During the session they will cover:

• How microservices differ from SOA or monolithic architectures
• Best practices for adopting and deploying secure microservices for production use
• Avoiding continuous delivery of new vulnerabilities
• Limiting attack vectors on a growing number of API endpoints
• Protecting Internet-facing services from resource exhaustion
