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 carrier pigeon. And
that’s going to send your customers to another site, and fast.
So let’s look at the three biggest performance mistakes many developers
make when they create a website and some simple ways to fix them.
Identify your audience. When developing a website, many organizations fail ... (more)
For the past few years, our friends at VMblog.com have run an annual
prediction series forecasting the trends most likely to drive adoption of
cloud and virtualization technologies in the upcoming year. This is the
second year in a row that they’ve invited me to contribute, and I thought
long and hard about the assignment. After a deep gaze into my crystal ball, a
deliberate shuffle of the tarot cards, and much careful contemplation, I
settled on six major predictions, six changes to how solution providers and
organizations will approach performance management in 2013.
Some of t... (more)
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)
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)
At the end of 2012, Apica conducted a massive load test for an election
campaign organization. It was the largest load test we ever conducted,
surpassing the two million virtual user mark we set earlier that year. The
load test clocked in at over 200,000 requests per second for an entire hour.
To put this in context, roughly 23,000 Google searches occurred every second
at the time.
At the end of 2013, we blew our own record out of the water. After being
contracted to conduct a load test for a well known government, we reached
over 620,000 requests per second with over 1 million ... (more)
