When Configuration Settings from Development Wreak Havoc in Production
By Asad Ali
As applications are promoted from the development environment to the CI or
the QA environment and then into the production environment, it is very
common for the configuration settings to be changed as the code is promoted.
For example, the settings for the database connection pools are typically
lower in development environment than the QA/Load Testing environment. The
primary reason for the existence of the configuration setting differences is
to enhance application performance. However, occasionally there are instances
where the application code is mistakenly promoted into production without
changing these settings. In such cases, such promotion of code can cause
performance havoc in the production environment. This blog describes one such

Yes, Lori has been reading the Internet again. And what she's been seeing
makes baby Lori angry. It also makes this former test designer and technology
editor cry. Really, I weep at both the excuses offered for such testing and
the misleading headline.
I have read no less than two contrived comparisons of "HTTPS" and "HTTP" in
the last two weeks purporting to demonstrate that secure HTTP is inarguably
faster than its plaintext counterpart, HTTP.
Oh, if only that were true.
See, the trick is that both comparisons (and no doubt many more will follow)
are comparing secure HTTP/2 wi... (more)

The widespread success of cloud computing is driving the DevOps revolution in
enterprise IT. Now as never before, development teams must communicate and
collaborate in a dynamic, 24/7/365 environment. There is no time to wait for
long development cycles that produce software that is obsolete at launch.
DevOps may be disruptive... (more)
The True Cost of Downtime
By Kevin Goldberg
Do you know how much your organization risks with every potential outage?
Application performance issues can impact away more than revenue, your brand
might take a substantial hit as well. Hundreds, thousands of potential
customers could take to Facebook, Twitter, Yelp, the App Store and voice
their complaints and give poor reviews simply because your app crashed,
stalled, or they weren’t able to successfully check out.
Unfortunately, application issues are inevitable. Even if your uptime SLA is
99%, your application would still be down ... (more)
Industry Insights: The Threat Behind Digital Transformation
By Jonah Kowall
The age of digital disruption is upon us, as the last decade alone has proven
in terms of technology and disruption with the progression of organizations
like Uber, Airbnb, and Netflix. We are also on the brink of new disruptions

construction, packaging, and many more. These not only come from startups
disrupting a sector, but companies being able to shift from their existing
focus areas to build on new opportunities. They’re driven interna... (more)
Revisiting the Anatomy of HTTP: Part I
By Arun Kejariwal and Mehdi Daoudi
One of the key driving factors behind the various web/mobile performance
initiatives is the fact that end-users’ tolerance for latency has
nose-dived. Several studies have been published whereby it has been
demonstrated that poor performance routinely impacts the bottom line, viz,. #
users, # transactions, etc. Examples studies include this, this and this.
There are several sources of performance bottlenecks, viz., but not limited
