Latest Updates in the HAProxy Data Plane API - Chad Lavoie - HAProxyConf 2021

The HAProxy Data Plane API now has the ability to get backends from AWS tags and Consul, upload SSL certificates, and other features that make it fit into modern configurations. In this presentation we will provide a brief introduction to the HAProxy Data Plane API and cover some of these new features in more depth.

Fostering Fearlessness: Working in the Middle of the Day Instead of the Middle of the Night

There’s no shortage of articles on CI/CD and how to run a configuration validation utility before reloading or restarting a service, but this type of validation is not the same as acceptance testing. Furthermore, these validations don’t always give you (or your leadership team) the confidence to allow you to make big changes to your Production Infrastructure during normal business hours, often preferring to err on the side of caution and scheduling a maintenance window when you might prefer to be in bed.

Annual Study: Hybrid IT Acceleration Has Increased Network Complexity and Lowered Tech Pros' Network Management Confidence

SolarWinds IT Trends Report 2022-Getting IT Right: Managing Hybrid IT Complexity examines the current state and areas of opportunity for technology professionals managing increased complexity as hybrid IT accelerates. The continued shift to hybrid IT drives increased levels of IT management complexity, but tech pros feel a lack of confidence in how to best manage it. Nearly half (44%) of tech pros said their organization manages hybrid IT complexity through training staff and adopting IT monitoring/management tools (37%)

Monitor and diagnose network performance issues with SNMP Traps

Monitoring your on-premise or hybrid infrastructure means keeping track of potentially thousands of devices, any one of which could be a point of failure. Additionally, silos between application and network teams can create visibility gaps that complicate troubleshooting. For network engineers investigating bottlenecks, being able to view real-time infrastructure health and performance data alongside application metrics is essential for ensuring their organizations meet key SLOs.

Outage in Egypt impacted AWS, GCP and Azure interregional connectivity

On Tuesday, June 7, internet users in numerous countries from East Africa to the Middle East to South Asia experienced an hours-long degradation in service due to an outage at one of the internet’s most critical chokepoints: Egypt. Beginning at approximately 12:25 UTC, multiple submarine cables connecting Europe and Asia experienced outages lasting over four hours. As I show below, the impacts were visible in various types of internet measurement data to the affected countries.

Optimizing Images for Web Performance with NGINX

Images are a constant source of pain when developing websites. There are many formats and resolutions a developer must consider in order to maximize web performance. You’ll often end up with a cartesian explosion of the same image in different sizes and formats to support different scenarios. For example, you don’t want to send a high res image meant for high DPI screens to a low DPI screen - you’d be wasting bandwidth and burning time. Using the right file format is equally important.

Optimize Continuous Delivery of Micro-Services Applications with Continuous Performance Testing

I often hear from customers who complain about how “classic” performance testing (i.e., end-to-end testing with high volume of virtual users) of their applications before release slows down the cycle time by several weeks. In addition, the testing significantly consumes both people and infrastructure (hardware and software license) resources.

How to Test for Packet Loss: A Complete Guide

Among all the inconveniences endemic to living in the 21st century, there are few as common as a faulty internet connection. Most everyone with internet access is familiar with the experience but perhaps less so with the reason why. There are several, but chief among them is packet loss. In this article, we’ll explore what packet loss is and show you some of the first steps to conducting a packet loss test. But first, let’s briefly review what a packet is.
