The move to software-defined wide area networks (SD-WAN) is happening rapidly, and on a large scale. However, many network operations teams are struggling to contend with the monitoring implications of these technologies. In this post, I’ll outline the visibility gaps posed by SD-WAN, and I’ll detail how DX NetOps by Broadcom addresses these gaps.

By running performance tests continuously and automatically, you can identify and correct performance regressions as they occur. One way to do this is by integrating performance testing into your development process. In this step-by-step post, we explore how to do just that, using Grafana k6 and GitHub Actions. k6 is an open source load testing tool to test the performance of APIs, microservices, and websites.

This guide goes into the fundamentals, practical applications and tips & tricks of using OpenTelemetry (OTel) to monitor your Next.js application. OpenTelemetry is gaining (a lot) of momentum outside of its historical niche of distributed, micro services based application stacks. But, as it turns out you can just as well use it for more traditional, three tiered, web applications and it comes with a host of benefits.

Every Python developer has heard about the GIL (Global Interpreter Lock) This lock simplifies memory management and ensures thread safety, but it also limits the performance of multi-threaded, CPU-bound programs because threads can’t run Python code in parallel. Here is a great explanation of why Python requires the GIL by Python’s creator, Guido van Rossum: Guido van Rossum: Will Python ever remove the GIL? | Lex Fridman Podcast Clips.

Modern Applications can use a lot of external services, some of those interactions are expected, others not so much. There could be many reasons for those unexpected interactions, ranging from security vulnerabilities and various malware to outdated code and various reporting and statistics software may report to its creator or a third party. These unexpected interactions can be a security risk, and may also raise privacy concerns.
