When it comes to data, let’s start with the obvious. Averages suck. As developers, we all know that percentiles are much more useful. Metrics like P90, P95, P99 give us a much better indication of how our software is performing. The challenge, historically, is how to track the underlying data and calculate the percentiles. Today I will show you how amazingly easy it is to aggregate and create SQL based percentile rollups with Postgresql and t-digest histograms!

Kubernetes (k8s) enables you to efficiently orchestrate container management, in the cloud or on-premises. As a whole, k8s provides many benefits, including features for self-healing, automated rollouts and rollbacks, load distribution, and scalability. However, k8s is a highly complex platform and requires extensive configuration.

It’s been shown that if you follow a proven collection of practices for developing, designing, testing, implementing, and maintaining your software, you will produce a much higher quality product. Over the past few years, we have seen an increasing number of cases of attacks on the application layer. The Open Web Application Security Project, OWASP, estimates that around one-third of web applications contain security vulnerabilities.

Test automation helps increase development speed while reducing cost and effort. In this article, we will share how to automate testing to help keep a test automation initiative on the right track with key tips for test execution, design and maintenance for large enterprise applications.

If you’re a developer of .NET supporting enterprise apps developed in the .NET framework, you should know how the .NET 5 would impact your current enterprise app. Moving forward, there will be only one .NET to target macOS, Windows, Linux, iOS, Android, and more. Along with the release, there are new .NET APIs, language features, and runtime capabilities. The look and feel of the code and project files in .NET 5 would be the same, regardless of the type of app being created.

As important as adding new features, app developers need to start placing more emphasis on the security aspect of the applications they design. After all, more app features mean more data residing within an app. Without proper security controls in place, that data can be vulnerable to intruders.

At Stackify, we’re all about helping you improve your application’s performance. We have actually developed two code profilers ourselves. Because of that, we like to think we know a thing or two about code profiling. Today I want to talk about the three different types of code profilers, describe the differences between them, and recommend some tools for your toolbox.

Development can successfully remove the bottlenecks created by waterfall methodology by improving development productivity through encouraging collaboration,continuous feedback loops, and automating processes. Collaboration. Feedback. Automation. These are the main building blocks of Development operations. However, not all Development implementations are successful. Why? Building blocks are not enough. You need to take these building blocks and design a Development pipeline that suits your needs.

One of the challenges when you’re starting out with Development is getting the lay of the land. There are a lot of tools out there. And when one of the goals of Development is continually improving your processes, it’s important for you to understand how those tools might fit in your infrastructure. At the same time, you want to be efficient. You don’t want to add tools that overlap with one another. Or tools that cost more than other effective alternatives.

If there’s one thing SRE professionals and Development engineers lack, it’s time. After all, engineers need to oversee a variety of processes—like ensuring operational stability, conducting integration testing, and maintaining cybersecurity—to make sure their apps are working optimally. The list goes on and on. With heavy workloads and tight deadlines, there’s little time to waste on software issues stemming from internal collaboration issues.
