Load Testing to Detect Advanced Persistent Threats

I’ve written before about how capacity planning and load testing tools can help companies prepare for a Distributed Denial of Service (DDoS) attack, but we’ve begun to see a new class of attacks emerge, called Advanced Persistent Threats (APT), whose aim is much more sinister than a slow response time or “page not found” error. What is an Advanced Persistent Threat? The intentions behind APT are all about espionage — not just state-sponsored espionage but also extensive and well-organized industrial espionage. APT is not about any particular technology or technique. The actual a... (more)

Lessons Learned from the Amazon Web Services Outage

On Monday, Amazon Web Services — the leading provider of cloud services — suffered an outage, and as a result, a long list of well-known and popular websites went dark.

Load testing like a developer

Creating highly targeted load tests for your web server doesn’t have to be complicated. And it won’t be, at least not if you know what to look for. The secret is to approach a load test with the mind of a developer. You’re not going to run a test just to punish your web server. You’re trying to gather valuable data that will aid you in keeping your web applications fast and responsive. To do this, let’s look at two simple steps to create a scientifically sound load test. 1. To plan your test, think like a user. The first step is to outline exactly what type of web experience you’re... (more)

Three Web Performance Mistakes and How to Avoid Them

Could you imagine NASA sending a rocket into space without testing it first? What about a racing team putting a brand new car on the track without taking it for a few laps to test the handling and stability? It seems to me that testing is inherent in every technical field — except for website development that is. Too often we see websites where it’s clear that design was the main priority, while testing the site’s functionality and user experience was just an afterthought. What you’re left with is a great looking website that feels like it is being sent over the Internet via car... (more)
