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. What does it mean to build a successful networking team?

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. As networks become distributed and virtualized, the points at which they can be made vulnerable, or their threat surface, expands dramatically.

For most enterprise NetOps teams, a discussion about the WAN is a discussion about the cloud. Whether it’s as simple as ensuring solid connectivity with a SaaS provider or designing a robust, secure, hybrid, and multi-cloud architecture, the enterprise wide area network is all about connecting us to our resources, wherever they are.

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. For cloud network specialists, the landscape for their observability efforts includes a mix of physical and virtual networking devices.

So far in this series, I’ve outlined how a scaling enterprise’s accumulation of data (data gravity) struggles against three consistent forces: cost, performance, and reliability. This struggle changes an enterprise; this is “digital transformation,” affecting everything from how business domains are represented in IT to software architectures, development and deployment models, and even personnel structures.

A cornerstone of network observability is the ability to ask any question of your network. That means having an unbound capacity to explore the tremendous amount and variety of network telemetry you collect. It means seeing trends and patterns from a macro level, but it also means getting very granular to pursue any line of analysis of your data. Collecting information from flow records, SNMP, streaming telemetry, BGP, eBPF, and so on is indeed very important.

Last summer we teamed up with the New York Times to analyze the re-routing of internet service to Kherson, a region in southern Ukraine that was, at the time, under Russian occupation. In my accompanying blog post, I described how that development mirrored what took place following Russia’s annexation of Crimea in 2014.

Cloud networking is the IT infrastructure necessary to host or interact with applications and services in public or private clouds, typically via the internet. It’s an umbrella term for the devices and strategies that connect all variations of on-premise, edge, and cloud-based services.
