Developing custom network functionality using SONiC

Market analyses claim that in the future, networking will shift more and more towards so-called Open Networking. Open Networking relies mainly on hardware and software disaggregation, i.e. with open standard bare-metal equipment and a choice of independent NOS (Network Operating System). Such an approach fits with the main industry trends, like Software-Defined Networking, virtualization, containerization and of course, cloud computing.\Other benefits of open networking include: Flexible architecture

Golang errors and how to handle them

Many programming languages base their error handling around exceptions. Some of them use exceptions when handling abnormal situations, while others use exceptions as a normal redirection in a control flow. For example, an object in Python throws the StopIteration exception when the iterator is exhausted. Go has a rather unique way of handling errors that is very different from the traditional focus on exceptions. In this article, I’ll take a closer look at Go errors and describe how handling them differs from dealing with this issue in other programming languages.

The popularity of Python for network test automation and more

Test automation is a rapidly and dynamically evolving element of software development. Automation saves time and resources in large-scale systems by transferring repetitive activities from human hands to a machine. Companies that want to achieve both qualitative and economic benefits are faced with selecting tools that can be used to fulfill those goals. Choosing the proper framework can be challenging, but the importance of the selection of the programming language itself cannot be overlooked. This article will present the advantages of Python for testing automation - one of the most recognizable languages used for automation.

ETL vs. ELT — What are they and when do we need them?

When we talk about data warehousing, we think of databases, which is only half of the solution. Data must be stored - this is why we need a database. But data must also be delivered into the database from a source. This is where ETL/ELT comes into the equation. Let's briefly explain what a data warehouse is and why we need one. It is a system used for storing and reporting data. Due to their design, data warehouses can process huge amounts of data, making lots of information available for business analytics.

What is data engineering?

In the past two decades, the digital world has been flooded with data. Most companies have completed digital transformations, and more and more users leave their digital footprint behind every day. All of this information can be turned into useful knowledge that allows companies to make data-driven decisions. This is where the process of data engineering takes place. Data engineering is a branch of data science. Data science is a broad term that includes all of the tasks that make data valuable - from gathering the data to storing, analyzing, and visualizing it.

From Kubernetes Ingress to Kubernetes Gateway API

If you've ever touched on application networking in Kubernetes, it's more than likely you've come across Ingress. However, it is worth knowing that Ingress has a worthy successor in the form of Kubernetes’ Gateway API. If you want to get familiar with this new API, this article is what you need. Ingress is a Kubernetes API object that has been widely used for many years. It allows you to handle traffic entering the Kubernetes cluster from outside and to route it to multiple Services running in the cluster.

SQL vs. NoSQL. The evolution of relational and non-relational databases

Databases are tools used daily by companies of all kinds. They make storing and transforming large amounts of data possible, and they are necessary for any data-driven business. But they had to come a long way before they became the databases we know today. Let’s take a look at the history of databases and learn how and why SQL and NoSQL have come to life. Since we, as humans, started collecting data, we also needed a way to store it. So naturally, the concept of a database came before computers. In the computer world, databases came into existence in the early 60s, when in 1962, the Oxford Dictionary first recognized the term “database” as a software system that stores and retrieves data.

Benefits of microservices. What should you know?

According to O’Reilly<sup>1</sup>, only 8% of businesses have no success with microservices. The rest notice at least some improvements. That many satisfied customers is the best proof that microservices are worth your attention and time if you want to bring your projects to the next level. This article will focus on how microservices can positively impact your business and how they can accelerate software development time. Microservices Architecture is a mode of development that focuses on developing a system as a set of small services.

Product design vs UX design — what is the difference?

The creation of a product, whether physical or software, is a challenging process. It is complex and consists of many stages. It also requires a team of various experts, each of them having a different set of skills and experience. Sometimes the positions might seem similar, almost the same even. Especially in the digital design realm, the responsibilities of particular individuals might overlap, which surprisingly could empower this complex and hard process. There are a lot of misconceptions surrounding the responsibilities of product designers and UX designers.

Network automation — why does it matter?

Network automation has been with us for a while and its popularity is growing exponentially, but still, there are a lot of companies that are resisting this structural revolution in the network realm. There's a joke from Big Switch Networks, that so far, the biggest shift in the network area was the migration from Telnet to SSH. Times change and the software-defined networks, along with network automation are playing a huge role in the future of many companies. That's why in this article, we would like to shed some light on network automation itself.

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?
