DevOps is speeding towards the IT world like a freight train and the hype
around it is deafening. There is no reason to be afraid of this change as it
is the natural reaction to the agile movement that revolutionized development
just a few years ago. By definition, DevOps is the natural alignment of IT
performance to business profitability. The relevance of this has yet to be
quantified but it has been suggested that the route to the CEO's chair will
come from the IT leaders that successfully make the transition to a DevOps
model. If this still seems foreign to you, I recommend reading up on DevOps
Blog from IT Revolution, the OpsCode Blog, and check out The Phoenix Project.
Despite all the talk around simple monitoring tools, breaking through the
walls between Dev and Ops still poses a real challenge. This is because of a
misunderstanding around Operations real purp... (more)
Agile Development Practices have widely been adopted in R&D Organizations. A
core component is Continuous Integration where code changes are continuously
integrated and tested to achieve the goal of having "potential shippable
code" at the end of every Sprint/Iteration.
In order to verify code changes agile team members write Unit or Functional
Tests that get executed against every build and every milestone. The results
of these tests tell the team whether the functionality of all features is
still given and that the recent code changes have not introduced a
Adding more memory to your JVMs (Java Virtual Machines) might be a temporary
solution to fixing memory leaks in Java applications, but it for sure won't
fix the root cause of the issue. Instead of crashing once per day it may just
crash every other day. "Preventive" restarts are also just another desperate
measure to minimize downtime, but, let's be frank: this is not how production
issues should be solved.

Two days before the Super Bowl people are not only betting on the winner, but
also on the best commercial. Will the millions of dollars spent really pay
off for the advertisers? We took a closer look at the Super Bowl Ad landing
pages for these Super Bowl Ads. Our synthetic monitoring showed huge
differences ranking from 1.4 to 10s+ load time. If these pages are already
slow prior to the big day, we wonder how they will do on Sunday and if there
is anything that can be done to speed things up.
With this blog we hope to give a wake-up signal to some of these companies.
