Top Stories by Alois Reitbauer

The increasing adoption of mobile applications as part of a company's online services leads to the question of whether we need to monitor it like other parts of our IT infrastructure. As they are part of our shipped application services we need to ensure they are working properly. However, not every application must be monitored the same way. In addition, monitoring always comes at a certain cost. We need people to take care of the monitoring, we have to prepare our applications to be ready for monitoring and we potentially also have to buy or at least integrate new monitoring tools. Before talking about how we have to monitor them we need to figure out whether and how much to invest in monitoring. As with classical applications, not every application is worth the effort of detailed production monitoring. An obvious decision criterion is business value. If the cost o... (more)

I collected the most common myths and truths about performance measurement overhead and will discuss them here. Truth: Performance Measurement Produces... (more)

Applying Maslow’s Pyramid to Application Performance

This time I take an a bit of an unconventional approach towards defining performance management. The idea for this article came through a number of customer engagements, where the same question came up over and over again: “How do we start with Application Performance Management and what should we do?” Over time I developed a simple model which I called the performance management pyramid. The basic idea is to assign performance management activities to several levels. Each level serves a specific need and builds on top of the lower ones. Just like a building it starts with the b...

Web Performance Optimization Use Cases - Part 4

In this edition of our WPO Use Case series I discuss another very important use case. Load Time Optimization is most likely the most vital use case from an end user perspective. At the same time it is also highly important from a business perspective as studies by ShopZilla or Google and Bing show that load times have immediate effects on user behavior. The higher the load, the less end users are interested in interacting with the page. Load time therefore has a direct relationship to user acceptance and also business goals. The goal of optimizing load times is to show relevant ... (more)
