In this post, we discuss the crucial differences between resilience versus redundancy in networking. Learn how to optimize your network for seamless performance.

What do network operators want most from all their hard work? The answer is a stable, reliable, performant network that delivers great application experiences to people. In daily network operations, that means deep, extensive, and reliable network observability. In other words, the answer is a data-driven approach to gathering and analyzing a large volume and variety of network telemetry so that engineers have the insight they need to keep things running smoothly.

This guide explores the benefits of embedded caching for ISPs and discusses deployment optimization strategies and future trends in CDN technology. Embedded CDNs help reduce network congestion, save costs, and improve user experiences. ISPs must carefully plan their deployment strategies by considering how each of the CDNs distributes content and directs end-users to the caches. They need to know both the CDNs and their network architecture in detail to build a successful solution.

A data-driven approach to cybersecurity provides the situational awareness to see what’s happening with our infrastructure, but this approach also requires people to interact with the data. That’s how we bring meaning to the data and make those decisions that, as yet, computers can’t make for us. In this post, Phil Gervasi unpacks what it means to have a data-driven approach to cybersecurity.

True observability requires visibility into both the application and network layers. For companies reliant on multi-zonal cloud networks, the days of NetOps existing as a team siloed away from application developers are over.

Network telemetry and DataOps play a critical role in enhancing network visibility. By combining both, organizations can improve network visibility and gain insight to help them optimize their network performance, improve security, and enhance the overall user experience.

It has now been over a year since Russian forces invaded its neighbor to the west leading to the largest conflict in Europe since World War II. Kentik’s Doug Madory reviews what has happened with internal connectivity within Ukraine over the course of the war in this analysis done for a collaboration with the Wall Street Journal.

Content delivery networks are an important part of the internet, as they ensure a short path between content and the consumers. The idea of placing CDN caches inside ISPs networks was created early in the days of CDNs. The number of CDNs with this offering is growing and ISPs all over the world take advantage of the idea. This post explains how this works and what to look out for to do it right.

Delivering on network reliability causes an enterprise’s data to become more distributed, introducing advanced challenges like complexity and data gravity for network engineers and operators. Learn concrete steps on how to implement cloud reliability and the trade-offs that come with it.

eBPF is a powerful technical framework to see every interaction between an application and the Linux kernel it relies on. eBPF allows us to get granular visibility into network activity, resource utilization, file access, and much more. It has become a primary method for observability of our applications on premises and in the cloud. In this post, we’ll explore in-depth how eBPF works, its use cases, and how we can use it today specifically for container monitoring.
