Resiliency is a network’s ability to recover and maintain its performance despite failures or disruptions, and redundancy is the duplication of critical components or functions to ensure continuous operation in case of failure. But how do the two concepts interact? Is doubling up on capacity and devices always needed to keep the service levels up? The truth is, designing a network that can withstand the test of time, traffic, and potential disasters is a challenging feat.

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.
