Under the waves at the bottom of the Earth’s oceans are almost 1.5 million kilometers of submarine fiber optic cables. Going unnoticed by most everyone in the world, these cables underpin the entire global internet and our modern information age. In this post, Phil Gervasi explains the technology, politics, environmental impact, and economics of submarine telecommunications cables.
What does it mean to build a successful networking team? Is it hiring a team of CCIEs? Is it making sure candidates know public cloud inside and out? Or maybe it’s making sure candidates have only the most sophisticated project experience on their resume. In this post, we’ll discuss what a successful networking team looks like and what characteristics we should look for in candidates.
As networks become distributed and virtualized, the points at which they can be made vulnerable, or their threat surface, expands dramatically. Learn best practices for preventing, detecting, and mitigating the impact of cyberthreats.
Today’s enterprise WAN isn’t what it used to be. These days, a conversation about the WAN is a conversation about cloud connectivity. SD-WAN and the latest network overlays are less about big iron and branch-to-branch connectivity, and more about getting you access to your resources in the cloud. Read Phil’s thoughts about what brought us here.
When coupled with a network observability platform, device telemetry provides network engineers and operators critical insight into cost, performance, reliability, and security. Learn how to create actionable results with device telemetry in our new article.
In the final entry of the Data Gravity series, Ted Turner outlines concrete examples of how network observability solves complex issues for scaling enterprises.
A cornerstone of network observability is the ability to ask any question of your network. In this post, we’ll look at the Kentik Data Explorer, the interface between an engineer and the vast database of telemetry within the Kentik platform. With the Data Explorer, an engineer can very quickly parse and filter the database in any manner and get back the results in almost any form.
In this article, Doug Madory uncovers the little-known “Russification” of Ukrainian IP addresses — a phenomenon that complicates the task of internet measurement and impacts Ukrainians connecting to the internet using IP addresses suddenly considered Russian.
Cloud networks introduce a multitude of costs that can become challenging to predict. Learn how to implement a cost-aware infrastructure through maximum visibility in cloud networking.
The advent of various network abstractions has meant many day-to-day networking tasks normally done by network engineers are now done by other teams. What’s left for many networking experts is the remaining high-level design and troubleshooting. In this post, Phil Gervasi unpacks why this change is happening and what it means for network engineers.
