Once upon a time, when dinosaurs roamed the earth, servers had to be built. A development team requested an environment for their code to run in, and a system administrator or infrastructure engineer plugged in a server and spent hours or days getting it ready to run code. Oh, and by the way, that was only one server of many …
The widespread use of automation and the quest for increasingly shorter development cycles can be considered the hallmarks of the current era of software development. Practices such as Continuous Deployment and Continuous Integration, which were unimaginable not that long ago, nowadays are commonplace techniques that most software professionals take for granted. In this scenario, designing and maintaining a functional CI/CD …
One challenge for developers beginning a new project is choosing between monolithic and microservice architecture. According to Camunda research, 63% of enterprise level companies have taken steps to apply microservice architecture. Let’s take a closer look at the benefits and implementation of microservice architecture and why enterprise level companies, like Amazon, Netflix, and Uber, are choosing this architecture over traditional …
As exciting as it can be to write new features in your ASP.Net application, our users inevitably encounter failed requests. Do you know how to troubleshoot IIS or ASP.NET errors on your servers? It can be tempting to bag on your desk and problem your annoyance. However, Windows and ASP.NET provide several different logs where failed requests are logged. This …
.NET Profilers are a developer’s best friend when it comes to optimizing application performance. They are especially critical when doing low level CPU and memory optimizations. But did you know that there are three different types of profilers? Traditional .NET profilers that track process memory usage, time spent per line of code and frequency of method calls. Lightweight profilers or other …
Digitalization is sweeping across many industries, creating a huge need for innovation. This innovation forces companies to be more agile and deliver faster.

Over the last decade, DevOps has become an important part of software engineering culture, influenced by the wide adoption of microservices, containers and cloud computing. A recent step in the evolution of cloud-based and microservice architecture is the serverless computing – a code execution model where the cloud provider takes total responsibility for the operating system and hardware management. The …
Debugging performance issues in production can be a pain and, in some cases, impossible without the right tools. Java profiling has been around forever, but the java profilers most developers think about are only one type: standard JVM profilers. However, using one type of profiler is not enough. Suppose you’re analyzing your application’s performance. There are multiple profiling activities which …
Imagine you’re driving a car, but there’s no windshield. You can’t see in front of you. On top of that, your car is full of friends looking out the side windows and yelling various things to you: “We should turn left!” “No, we should turn right!” “I’m pretty sure the next turn is in two miles.” In this scenario, how …
The software development life cycle (SDLC) started to become a formalized process for software development in the 1960s. That’s pretty much when software systems started to exist. With its loosely defined development phases, the SDLC has become a software development term that gets a lot of people talking. The SDLC, however, is more of an acronym packed with meaning than …
Monitoring an application’s performance is one of the hardest challenges in software development. That’s true for virtually any programming language and platform. Java performance monitoring presents some unique challenges of its own. For instance, one of those challenges has to do with garbage collection. Java features automatic memory management, which frees the developer from having to manually dispose of obsolete …
DevOps is a tech industry buzzword that refers to the collaboration of a software development team and operations teams within a company.

Need help on how to monitor IIS? This guide covers the basics, including HTTP ping checks, IIS Application Pools, and important Windows Performance Counters. In addition, we’ll take a look at how to use an application performance management system to simplify monitoring IIS and get more advanced IIS performance monitoring for ASP.NET applications. Without monitoring IIS performance, you could end …
Microservices are increasingly used in the development world as developers work to create larger, more complex applications that are better developed and managed as a combination of smaller services that work cohesively together for more extensive, application-wide functionality. Tools such as Service Fabric are rising to meet the need to think about and build apps using a piece-by-piece methodology that is, …
