Microservices. The real deal or a grand delusion?

According to Statista, in 2021, 85% of respondents (organizations employing a minimum of 5,000 employees) claim that they use microservices. Doubtless, adopting microservices can seriously benefit an organization and visibly improve the quality of the products and services it develops. However, it is crucial to do so properly to see positive results. This article will highlight the most important aspects you should be aware of before implementing microservices architecture into the organization. Microservices architecture, as stated by Fowler, "Microservices is a subset of SOA (service-oriented architecture) with the value being that it allows us to put a label on this useful subset of SOA terminology.

Envoy configuration in a nutshell: Listeners, Clusters and More

In the previous blog post, I briefly discussed what Envoy Proxy is and where it can be used. If you’re not familiar with Envoy I strongly suggest reading the previous piece first. This text is meant for developers or devops engineers who want to learn more about how to make the most of its functionality. We will discuss how Envoy Proxy actually works and how it should be configured. Let’s start with a simple example. This demonstrates the most common situation when the client initiates a connection with Envoy Proxy as it tries to reach the server.

How to build masonry layout in 5 minutes?

Have you ever heard of the so-called masonry layout, as seen on Pinterest? In short, it consists of elements of unequal size stacked one after the other in the direction of the line. As they move to the next line, the items will move into the gaps left by the smaller items in the previous line. Preparing this type of layout is not a simple task. In 2010, David DeSandro implemented the 'Masonry' library to create this type of layout (Masonry library). However, the implementation of this layout is pretty complicated.

Enzyme vs React Testing Library — what to choose?

When developers work on frontend applications, there is a lot of manual testing of written code, to make sure that everything works well in the UI. This process is time-consuming, and we want to make sure that after we finish the work on the feature, it behaves as expected - this is where tests come into play. This article will compare two popular component testing tools for React applications - Enzyme and React Testing Library. At the end of 2015, EnzymeJS was released to the public and started getting traction immediately.

How to use the Google HEART framework to set up user-centered metrics

A seamless user experience is essential if you want your software to work effectively and fulfill its business objectives. However, building a user-friendly app or website is only possible with thorough UX research. The larger the organization, the more difficult it can be to collect the data. To meet the needs of large-scale businesses, in 2010, Google UX research experts came up with a perfect way to measure the user experience. They created the HEART framework that specifically targets this kind of measurement.

The Best Tools for Functional Testing in Networks

Software testing is an integral part of the software development life cycle (SDLC). Simply put, the primary goal of software testing is to find bugs and fix them as fast as possible, preferable at the early stages of the SDLC, and ensure bug-free software or software products. There are many different types of testing, but for this article's purpose, we will focus on functional testing. By readingthis article, you'll learn about functional testing in terms of network-related projects, what it is and whether it is actually needed.

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?
