What are SmartNICs? The different types and features

Nowadays, network applications have evolved to provide more complex and user-oriented features. This evolution comes with a cost: increased CPU resource usage on the server side. For that reason, a solution that enables network function offloading and improves application performance is sorely needed. According to an Intel report, only 2% of respondents don't plan to deploy SmartNICs in the near future. This number is meager, but it could be useful to consider why this small group remains unconvinced.

Day 0/Day 1/Day 2 — the software lifecycle in the cloud age

The topic of "Day 0/Day 1/Day 2" in the context of the software lifecycle is very prominent in the professional IT media today. Presentations and conference talks are often focused on making software development processes effective and easy to manage. To do so, it is necessary to clearly define the notions that are used. The basic terms "Day 0/Day 1/Day 2" are often understood intuitively, which can introduce some ambiguity when talking about the software life cycle. For that reason, I have decided to define them more accurately to show the entire process of software development and how they are used in real projects.

How long (for real) does it take to make an application?

If you're planning on building an app, you want to know how long the process will take. And that is entirely understandable—you have to coordinate the development process with many other aspects, such as marketing and advertising campaigns, product introduction to the market, predicting what upcoming trends or regulations could impact your business, etc. However, there is no single answer to the question, "How long does it take to make the app?". Oh, sorry, there is one- "it depends." That’s not very satisfying but it's the reality—do not believe any article that gives you a specific answer.

The difference between Quality Assurance and Quality Control in software development

Quality should be a habit for every organization, no matter the industry. If you deliver products or services, the quality level is something you should constantly monitor. The major components of quality management are Quality Assurance and Quality Control. These terms are often confused with one another and hence, used interchangeably. However, there are a number of distinctions between the two. Let’s explain the difference between Quality Assurance and Quality Control. Quality Assurance is the part of quality management that is focused on providing confidence that all quality requirements are fulfilled.

Where are my keys? React keys

We all have ways of remembering where we last put our apartment or car keys. After all, we all know the fear of losing them, don’t we? Applications written in React also have keys. And they are as important as those to your apartment. Or even more sometimes - especially when a deadline is around the corner and your React code is bright red. From this article, you'll learn about React's mysterious keys - both in theory and practice, what you need to know about indexes, and more. Last but not least, it will cover how to avoid the terrifying red color warning.

Network traffic troubleshooting during VNF lifecycle — aspects of Tungsten Fabric flows

Here’s a question that gives telco operators sleepless nights: How do you go about building and maintaining your telco cloud to maintain carrier-grade requirements while bringing hyper-scale public cloud pronouncements and promises to the telco world? One of the main challenges to achieving the above is to provide network monitoring, alerting and troubleshooting. Monitoring such complex infrastructure is not only about monitoring the physical health of the hardware the services rely on. It must also extend to the state of VMs or containers serving either control plane functions or a that runs a specific network function.

What is software testing and why is it important for the SDLC

Developing any application is a long-term process engaging the whole team. After months of intensive work, everyone eagerly awaits the results—both your team and your client. You’re planning to release the product to a deadline—that’s obvious. Keeping errors to the bare minimum throughout the application development process helps you meet the deadline. There will definitely be errors—we are all human after all, and mistakes are inevitable—but effective use of software testing helps to limit such unpleasant surprises.

Best UX design and prototyping tools

User experience is one of the most important aspects of product development. The main objective is to create a clear environment for users so they can easily navigate through your product. Every successful app, management system, software, platform, or website has to be accessible to the target end user. Designing such an experience requires not only a great idea but also great presentation; to be able to communicate well with your clients and to channel your ideas into something tangible. Designing a UX prototype, of course, being only the first phase of the whole process; later on you have to seek feedback in order to implement upgrades and fixes.

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?
