Today on the Tech Bytes podcast we dive into a real-world SD-WAN deployment. Our sponsor is Aruba and we’re talking with Aruba ESP customer Alabama ONE, a credit union. Our guest is Bobby Umfress II, Director of IT and Operations at Alabama ONE.

At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.
In the following network—
There are many reasons an operator might want to select which neighboring AS through which to send traffic towards a given reachable destination (for instance, 100::/64). Each of these examples assumes the AS in question has learned multiple paths towards 100::/64, one from each peer, and must choose one of the two available paths to forward along.
Examining this from AS65006’s Perspective …
Assuming AS65006 is an edge operator (commonly called enterprise, but generally just originating and terminating traffic, and never transiting traffic), there are several reasons the operator may prefer one exit point (through an upstream provider), including:
This article offers a response, describing how to introduce an uncorrelated monitor-of-monitors into the data center to provide real-time visibility that survives when the primary monitoring systems fail.
Summary of the AWS Service Event in the Northern Virginia (US-EAST-1) Region, This congestion immediately impacted the availability of real-time monitoring data for our internal operations teams, which impaired their ability to find the source of congestion and resolve it. December 10th, 2021
Standardizing on a small set of communication primitives (gRPC, Thrift, Kafka, etc.) simplifies the creation of large scale distributed services. The communication primitives abstract the physical network to provide reliable communication to support distributed services running on compute nodes. Monitoring is typically regarded as a distributed service that is part of the compute infrastructure, relying on agents on compute nodes to transmit measurements to scale out analysis, storage, automation, and Continue reading
Today, in partnership with CrowdStrike and Ping Identity, Cloudflare is launching the Critical Infrastructure Defense Project (CriticalInfrastructureDefense.org). The Project was born out of conversations with cybersecurity and government experts concerned about potential retaliation to the sanctions that resulted from the Russian invasion of Ukraine.
In particular, there is a fear that critical United States infrastructure will be targeted with cyber attacks. While these attacks may target any industry, the experts we consulted with were particularly concerned about three areas that were often underprepared and could cause significant disruption: hospitals, energy, and water.
To help address that need, Cloudflare, CrowdStrike, and Ping Identity have committed under the Critical Infrastructure Defense Project to offer a broad suite of our products for free for at least the next four months to any United States-based hospital, or energy or water utility. You can learn more at: www.CriticalInfrastructureDefense.org.
We are not powerless against hackers. Organizations that have adopted a Zero Trust approach to security have been successful at mitigating even determined attacks. There are three core components to any Zero Trust security approach: 1) Network Security, 2) Endpoint Security; and 3) Identity.
Cloudflare, CrowdStrike, and Ping Identity are three of Continue reading
Everyone wants smooth, shiny, and vibrant skin. But unfortunately, not everyone is privileged to have it. Various methods have been used to give this result and one of the popular methods is the manual use of exfoliating gloves. This trend has been acceptably used by many. It’s a very convenient and easy way to fix dry and even oily skin. It is a coarse-textured glove that could be worn by anyone for convenient use. The following about exfoliating gloves shall be considered:
Exfoliating gloves work by getting rid of the dead skin cells on your skin. The skin naturally sheds and most times, the dead cells stay on the skin and could even clog your pores. Using exfoliating gloves could help scrub out the dead cells away thereby allowing products to penetrate the skin. With consistent use, it can also increase the production of collagen leading to clearer and smoother skin and improving the overall look of your skin. It could also reduce the appearance of acne and acne scars and give Continue reading

At Cloudflare, we've watched in horror the Russian invasion of Ukraine. As the possibility of war looked more likely, we began to carefully monitor the situation on the ground, with the goal of keeping our employees, our customers, and our network safe.
Attacks against the Internet in Ukraine began even before the start of the invasion. Those attacks—and the steady stream of DDoS attacks we’ve seen in the days since—prompted us to extend our services to Ukrainian government and telecom organizations at no cost in order to ensure they can continue to operate and deliver critical information to their citizens as well as to the rest of the world about what is happening to them.
Going beyond that, under Project Galileo, we are expediting onboarding of any Ukrainian entities for our full suite of protections. We are currently assisting more than sixty organizations in Ukraine and the region—with about 25% of those organizations coming aboard during the current crisis. Many of the new organizations are groups coming together to assist refugees, share vital information, or members of the Ukrainian diaspora in nearby countries looking to organize and help. Any Ukrainian organizations that are facing Continue reading
Hello my friend,
We’ve been preparing this blogpost for quite a while, but for various reasons it was put on the back burner. Now we finally are bringing this back to light. We’ll go over a practical use case of automation of 6WIND configuration with Ansible and NetBox relying NETCONF.

The answer is, as usual: it depends. With our passion to automation, we would say: yes, definitely you should automate everything. But this is possible, only if you have unlimited resources (time, money, people). In reality, all the resources are limited and, moreover, may be even scarce. In such a case you would need to choose, where would you obtain the biggest leverage from automation. For example, some tasks are more frequent or time consuming than others. Clearly they are to be automated.
How to find them? Join our automation training and you will find that out!
