What is micro-frontend architecture? A comprehensive overview

Modern customers have more requirements for a web app than ever before. With the wide choice of mobile and web applications that exists today, it is not enough for an application to simply fulfill its functions as advertised. It also has to be highly available, scalable, and fast, and updates and new features have to come out regularly, and without a hitch. For quite some time already, creating a successful modern web application has meant overcoming the limitations of a monolithic backend. One of the most popular approaches for that is using microservices for your backend development.

Trunk-based development: best practices and strategies

All development teams strive for an agile, flexible, and efficient software development process. There are many ways to achieve it. Trunk-based development is one of the more modern approaches that is gaining attention. Let’s take a closer look at what it is, how it works, and what benefits it can bring your team. Trunk-based development is a management practice. It is a source-control branching model focusing on a single branch of code called the trunk. Trunk-based development aims to keep the trunk ready for deployment at all times.

SRE vs. DevOps — what’s the difference?

DevOps and Site Reliability Engineering (SRE) are two approaches in modern software development and operations. DevOps is a methodology that embraces lean and agile principles, focusing on continuous delivery and automation throughout the software development life cycle. This approach enables frequent releases and efficient software development and deployment processes. In 2003 SRE emerged as a solution designed to support the construction of large-scale applications. Today, SRE involves a team of experts with development backgrounds, applying engineering practices to tackle common challenges in production systems.

Tungsten Fabric is closing down — what next?

Tungsten Fabric is an open-source project developed under the umbrella of the Linux Foundation. It serves as an important part of many network infrastructures. The project is, however, ending its development. Due to the community’s decision, active development and project services have ceased but the resources will remain accessible until August 1, 2024.

Platform engineering — everything you need to know

As the popularity of cloud-native applications rises steadily, software development becomes a more and more complex process. With multiple smaller autonomous teams working on separate components of your application, where each team often has a different tech stack, an isolated codebase, and even separate release procedures, it is not surprising that the amount of overhead snowballs too. Modern DevOps best practices like containerization, automated continuous deployment, infrastructure as code, and others allow developers to shorten the release cycle and develop cloud-native applications in any type of cloud environment, using complex architectures, especially those based on microservices.

Network devices benchmarking methodology — RFC 2544 performance testing

Networking devices are complex and characterizing their performance is not easy. One must not judge performance based only on the number and type of ports. On the other hand, the performance figures that can be found in marketing materials may not be conclusive. Therefore, some while ago, the effort was made to create a unified benchmarking methodology to produce reliable, repeatable and comparable results. In this short article we’ll describe the basic performance metrics of networking devices and the methodology used to measure them.

Reliability engineering — its significance and key principles

Choosing a product or a service to buy is a complex process. Your own tastes play an important role, of course, but very often product reliability is what impacts your decision most of all. It is especially important when you are looking at something that can potentially serve you for many years to come. Nobody likes spending a ton of money on a device that works right now but will fail in a couple of months. However, we can all agree that nothing lasts forever. Any product or system can fail, which is why warranties exist.

Enhancing the user experience with end user experience monitoring (EUEM)

In today's digital landscape, where user satisfaction is paramount, organizations strive to deliver seamless and optimized experiences to their end users. End user experience monitoring (EUEM) plays a pivotal role in achieving this goal. Unlike application performance monitoring or network performance monitoring, EUEM focuses specifically on measuring and improving the user experience. In this article, we will explore the concept of EUEM, discuss its advantages, highlight the potential long-term benefits, and delve into the specific metrics, visualization, and tools used in EUEM.

Projects in Remix: best practices and lessons learned

Remix is a popular React framework, often used for its ease and speed of development for web applications. However, just like any technology, it has its shortcomings. They are not visible at first sight - you might come across them only once you’ve started a project using this technology. In this article, an experienced developer shares his mistakes to avoid and best practices to follow while working on web applications in Remix. Remix is a React-based frontend framework curated by React ecosystem veterans.

Navigating the module maze: history of JavaScript module systems

JavaScript was designed to handle uncomplicated scripting tasks that we know from everyday life - handling events, updating content, etc. However, nowadays we write huge and complex apps in JS. This distinction between initial design and current usage is a root cause of a lot of frustration in the JS community. Let’s look at one of these causes of frustration and confusion: modules. Modules were one of those topics which I've never felt like I fully grasped. I knew about ESM and CJS, the differences between them, and some history.

FD.io’s VPP’s mechanical sympathy – thread and memory management techniques explained

We've previously explained how VPP processes packets in vectors as opposed to processing each packet end to end. But how is this processing spread across CPU cores? How exactly is a vector of packets structured?
