Using DevOps to Simplify Disaster Recovery

Valley-Free Routing

Reading academic articles about Internet-wide routing challenges you might stumble upon valley-free routing – a pretty important concept with applications in WAN and data center routing design.

If you’re interested in the academic discussions, you’ll find a pretty exhaustive list of papers on this topic in the Informative References section of RFC 7908; here’s the over-simplified version.

BiB 053: Mode.net’s Cloud Private Network For Your SD-WAN

Mode briefed Ethan Banks about their cloud private network. Whoa! Thought Mode was an SD-WAN company? Not quite. Mode partners with several SD-WAN platforms so that it's easy to stand up a tunnel from your SD-WAN forwarders to Mode's private network. That makes Mode a network alternative to private MPLS that integrates with your SD-WAN fabric.

Worth Reading: VMWare wants to rearchitect your containers

One of the compelling advantages that Pivotal Container Service (PKS) has exhibited over the other container platforms in which VMware has invested, is that it promises to be an implementation of “plain vanilla Kubernetes,” requiring nothing special and no exclusive treatment from developers. —Scott M. Fulton III @The New Stack

IDG Contributor Network: What’s wrong with Cisco running SD-WAN on your routers?

Cisco’s announcement earlier this month that it will add the Viptela SD-WAN technology to the IOS XE software running the ISR/ASR routers will be a mixed blessing for enterprises.On the one hand, it brings SD-WAN migration closer to Cisco customers. On the other hand, two preliminary indicators —  one-on-one conversations and Cisco’s refusal to participate in an SD-WAN test —  suggest enterprises should expect reduced throughput if they enable the SD-WAN capabilities on their routers.Cisco’s easy migration to SD-WAN By including the SD-WAN code with IOS XE, Cisco will provide a migration path for the more than one million ISR/ASR edge routers in the field. There’s been a lot of conversation as to whether or not SD-WAN is going to kill the router performance. Delivering SD-WAN code on the ISRs is Cisco’s answer: routers are here to stay but they’ll morph into SD-WAN appliances.To read this article in full, please click here

Research: DNSSEC in the Wild

The DNS system is, unfortunately, rife with holes like Swiss Cheese; man-in-the-middle attacks can easily negate the operation of TLS and web site security. To resolve these problems, the IETF and the DNS community standardized a set of cryptographic extensions to cryptographically sign all DNS records. These signatures rely on public/private key pairs that are transitively signed (forming a signature chain) from individual subdomains through the Top Level Domain (TLD). Now that these standards are in place, how heavily is DNSSEC being used in the wild? How much safer are we from man-in-the-middle attacks against TLS and other transport encryption mechanisms?

Three researchers published an article in Winter ;login; describing their research into answering this question (membership and login required to read the original article). The result? While more than 90% of the TLDs in DNS are DNSEC enabled, DNSSEC is still not widely deployed or used. To make matter worse, where it is deployed, it isn’t well deployed. The article mentions two specific problems that appear to plague DNSSEC implementations.

First, on the server side, a number of Continue reading

Welcome, WP Engine!

We’ve had the tremendous pleasure of working with WP Engine for nearly 5 years, starting when both companies employed less than 100 people in total. From the beginning, we noticed striking similarities between our two companies—both were founded in 2010, both are incredibly passionate about their customers’ success, and both strive to make their technology as simple and accessible as possible. Fast forward to 2018: with WP Engine already leveraging Cloudflare for DNS, thousands of mutual WP Engine and Cloudflare customers, and millions of WordPress websites already protected behind Cloudflare, it was a no-brainer to formally partner together.

Today, we are thrilled to announce WP Engine as a Cloudflare partner! The joint offering, Global Edge Security powered by Cloudflare, integrates WP Engine’s platform with Cloudflare’s managed web application firewall (WAF), advanced distributed denial of service mitigation (DDoS), SSL/TLS encryption, and CDN across a global edge network to deliver the world’s most secure and scalable digital experience on WordPress today.

We couldn’t be more excited about our opportunity to collaborate with WP Engine to deploy business-critical security and CDN edge services to Enterprises and SMBs globally.

IDG Contributor Network: The rise of EVPN in the modern data center

Over the last few years, I have been sprawled in so many technologies that I have forgotten where my roots began in the world of data center. Therefore, I decided to delve deeper into what’s prevalent and headed straight to Ivan Pepelnjak EVPN webinar hosted by Dinesh Dutt.I knew of the distinguished Dinesh since he was the chief scientist at Cumulus Networks and for me; he is a leader in this field. Before reading his book on EVPN, I decided to give Dinesh a call to exchange our views about the beginning of EVPN. We talked about the practicalities and limitations of the data center.
