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.

In other cases we get called when t... (more)

Many Web Sites that use JavaScript frameworks to make the site more interactive and more appealing to the end user suffer from poor performance.
