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...

How Bon-Ton Stores Align Business Goals with IT Requirements

Two or three times a year, Bon-Ton Stores products are featured on Jill's "Steals and Deals" segment on the "Today Show." The products are promoted with huge discounts. As soon as the segment first airs on the East Coast, the "Steals and Deals" site displays the featured products, with links to Bon-Ton's site, usually directly to the deal itself with a special promotion or coupon code.

Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code… Too often we from dynaTrace are introduced when it is already very late in the development cycle. Most of the time we're introduced when the first performance test results show bad response times and nobody understands why it is that slow. In other cases we get called when t... (more)

How to Avoid the Top Five SharePoint Performance Mistakes

SharePoint is without question a fast-growing platform and Microsoft is making lots of money with it. It’s been around for almost a decade and grew from a small list and document management application into an application development platform on top of ASP.NET using its own API to manage content in the SharePoint Content Database. Over the years many things have changed – but some haven’t – like – SharePoint still uses a single database table to store ALL items in any SharePoint List. And this brings me straight into the #1 problem I have seen when working with companies that im... (more)

How ASP.NET PostBacks and Redirects Work

Last week I got the following two questions from one of our clients “We use ASP.NET PostBacks but can’t find the PurePath for the request triggering the PostBack handler – any hints?” “We see many ThreadAbortExceptions in our ASP.NET Application and we are not sure why they happen – are they expected?” Time for a little blog that gives some internals on PostBacks as well as Redirects (which are commonly used in PostBack handlers). What is a PostBack and how does it work? It’s not my intention to write the 50th blog post about PostBacks – I’d rather recommend checking out the follow... (more)
