Vendor API Integrations: Developer Beware 

Posted by Mitchel on Permalink

Since I started IowaComputerGurus in early 2006 I have worked on more than 100 different vendor API integrations.  Now two integrations have been the same, even if they are both going to the same vendor API.  Each integration project is a unique beast, the business requirements however similar are exactly that, similar.  The small changes, the small tweaks that you might have from one client to another on the same platform can be catastrophic.  Having done so many of these, I thought I had seen it all, from poor API's, to poor support, and everything in-between I could go on for days with the things I've experienced over the years.  However, after two recent experiences, by far the most horrible I've ever experienced I thought I'd share a few lessons learned to help others out there learn from my experience over the last 4-6 months.

Load Testing Your Application: Art or Science? 

Posted by Mitchel on Permalink

Earlier this year I blogged about this importing of understanding and knowing how your application will perform under load.  (See it here).  After receiving a lot of questions from individuals wanting to learn more about "how" they can load test their applications and the tools that I use when testing applications I thought it would be good to follow up with a post to shed a bit of light on the process.

Understanding the Logistics of Moving Websites 

Posted by Mitchel on Permalink

Recently for a number of reasons I've been working with individuals that are taking a website and moving them from one hosting provider to another.  Sometimes these moves are taking the existing site as is, other times it is migrating to a "new site" at the same time.  However, after doing at least 10-12 of these in the past few months a few common points of "confusion" have come to light.  As such, due to popular request I'll lay out the basics of how to move a website from one hosting provider to another and discuss the component parts that are involved in such a move. Although a bit "off" from my normal development or performance topics this is still a very real thing for many people!

Improving Web Application Performance - Part Three Client Side Considerations 

Posted by Mitchel on Permalink

In the first two parts of this blog series we introduced the importance of defining metrics prior to starting any performance optimization activities and the importance of identifying any user or role based issues.  In this part of the series we start to dive into the actual optimization part of the process.  I will start by introducing key concepts to look for, and then we will review the tools of the trade that can be used to help identify trouble points.  It is important to note that the information contained in this post is 100% applicable to ALL server side languages, regardless of .NET, PHP, Java, or anything else you might select to use.

Improving Web Application Performance - Part Two Users & Environment 

Posted by Mitchel on Permalink

Now that we have a set of metrics to use to validate the performance of our web application we can now start to dive deeply into resolving issues.  The first step in this journey is actually a step often overlooked by those that I encounter.  Professionally speaking 3 in 5 performance consultations that I am involved with are actually resolved by taking the points in this post into consideration.  So lets get started looking at users & environment.

Improving Web Application Performance - Part One Metrics! 

Posted by Mitchel on Permalink

For the last four or five years I have given a number of presentations on improving the performance of web applications, sometimes specifically focusing on DNN other times taking more broadly on ASP.NET.  However, the most popular of all presentations that I have given on Web Application performance was a session that took a broad look at application performance not only from a server side but also a client side application.  This talk was actually tailored to users that came from many application development backgrounds.  In this blog series I will share the information that was contained in that talk as well as a few more items of consideration that I have learned along the way.
