Clean architecture — everything you need to know

Many developers are aware of the clean code principles but there is a further way to level up, clean architecture. Not many are aware of the concept of clean architecture, although it is definitely worth exploring. My own experience proves that implementing clean architecture principles in your project can solve a number of issues. In this article I decided to take a closer look at what clean architecture means and why it can be important. Probably every developer and project manager has met this situation at least once in a career: a project shows rapid growth in the beginning then slows down or even becomes completely stuck.

Data lake vs. data warehouse — differences in data management

The day-to-day activities of any organization bring in a lot of information. This data needs to be tracked, stored, and eventually analyzed to allow the business to learn and grow. The bigger the organization, the more data it has, so where a simple database used to be enough for data storage, increasingly often new solutions are required. When it comes to managing big data, i.e. vast amounts of data from multiple data sources in multiple formats, two solutions have become very popular over the years: data warehouses and data lakes.

React confetti — let’s celebrate with JavaScript libraries!

Anniversaries, big and small achievements, public or religious holidays. We are looking for opportunities to celebrate them in our lives, as it gives us joy and happiness. It can be useful and fun to include this experience even in an otherwise ‘Very Serious And Important Application’. This article will focus on the confetti effect – how can you create it, what solutions can be helpful, and if it is a real thing to celebrate. In the text, you will also find code examples to make this journey more enjoyable!

Top 6 frontend trends for 2023 and beyond

Trends can come and go rather quickly, and that is especially true for software frontend development. Still, every business owner wants their application to beat the competition, and simply attracting new users is not enough, it is important they continue using the service. Nothing helps in this ongoing battle like making sure your web apps or mobile apps offer the best user experience to customers, which means it is totally worth it to keep up with the latest advancements in the field of frontend development.

SONiC adaptation for custom functionality — the PoC reveal

In the previous part, we introduced both the higher and the lower level concepts necessary for understanding the use case scenario as well as a proposed solution, starting from its prerequisites through to the design and finally the implementation. In this concluding article of the series, we want to eventually answer the initially-posed question: can we adapt a SONiC switch to be able to deliver a custom functionality? In our case, a load balancing feature for GTP-U. In order to conduct this PoC we needed to:

CloudOps — what do you need to know about cloud operations?

Modern businesses often scale quickly and therefore require expanded data center resources. Or more simply, they do not want to invest a huge amount of capex in expensive hardware in advance - they prefer to follow a “pay as you grow” model. In that case, moving to a public or hybrid cloud environment is often the best solution. However, that is easier said than done, and this process could be hard to perform without an experienced team. Finally, moving to the cloud requires modifications to the processes of data center operations.

The upcoming SmartNICs Trends for 2023

Modern network infrastructure is in a state of constant evolution to meet the ever-growing demand for improvements in fields like connectivity parameters, infrastructure flexibility, or overall power consumption. Innovators on the market are trying to answer all those needs, and with this article, we would like to shed light on some of the trends resulting from those efforts. SmartNICs extend the boring NIC domain with “smart” elements. Different platforms can define their “smart” elements differently, but overall, those elements aim to improve the general parameters of network connections, reduce power consumption, and increase the flexibility of network infrastructure.

Management vs. Control vs. Data Planes in a Network Device

An application, a system or even a simple device is made up of several components, each of which performs specific functions to the best of its ability, while leaving other tasks to other components which are dedicated to taking care of them. For example, a web application may consist of a HTTP server which provides the UI, a database server which keeps information about users, and a content server where images and videos are stored. Such an approach to dividing responsibilities is no different in networking devices, where hardware and software components work together to analyze and forward traffic according to the configuration applied by the administrator.

Enhancing SONiC — the process of developing custom network functionality

In the previous article, we introduced our reasons for exploring SONiC’s potential in terms of building new network functionalities, presented a use case, and described how we approached the task on the logical level. In this part, we want to share the experience we have gained through the development process. Note: please do not treat this as a comprehensive developer’s guide. What we explain here is our process and the key takeaways from it, which we believe might come in handy for other SONiC developers.

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?
