SDN vs traditional networks: revolution or evolution?

SDN is definitely a buzzword in the networking world. Software-defined networks are now gaining momentum among enterprises. But is this a truly disruptive technology that is going to replace legacy networks? Or is it a logical step forward in the evolution of the network? In this blog post I will discuss these questions. As I see it in the introduction to SDN, this is an evolutionary step for networks, not a revolution. Considering the benefits SDN technology offers or even starting to adopt it does not mean sweeping aside the traditional network as we know it.

What are the benefits of SD-WAN? In a word, legion

Software-defined WAN is becoming increasingly popular, and for good reason—it effectively solves a number of important challenges posed by traditional WAN architecture. Reduced costs, increased application performance, more flexible network topology, faster deployment and improved security are the main benefits SD-WAN offers. Read on to learn more.A WAN, or Wide Area Network, is the computer network spanning a wide geographical area (regions, countries or even world). You need a WAN when you have a number of geographically distributed local networks that need to communicate with each other.

Edge computing and virtualization — living on the edge

Cloud offers considerable benefits to businesses. Yet in some cases where low latency is critical, it has serious drawbacks. An emerging paradigm of edge computing is the answer to these problems. In 2016, Cisco announced the beginning of the Zettabyte Era. Since then, the amount of data produced and processed has increased zettafold, if you will. This is especially true when you look at M2M applications (machine-to-machine or more commonly referred to as Internet of Things—IoT) such as video surveillance, healthcare monitoring, the smart home, smart meters and the like.

The difference between SDN and NFV — a simple guide

Network Function Virtualization (NFV) and Software Defined Networking (SDN) technologies are similar and can easily be mistaken for one another. Given their growing popularity of late, it is good to know what SDN and NFV stand for, why they are so popular and what business benefits you can expect from them. In 2016, Cisco published the report “The Zettabyte Era: Trends and Analysis” announcing that by the end of 2016 annual global IP traffic would pass a zettabyte. To be mathematically precise, a zettabyte is a measure of storage capacity equal to 1021 (1,000,000,000,000,000,000,000) bytes.

How to create a WordPress custom theme for better site performance

Wordpress is no doubt the most popular blog platform. It’s easy to learn and set up even for people without technical skills. Additionally, you can use plenty of themes both free and premium. However, using premium Wordpress themes may result in decreasing load time and thus hamper your website’s performance. Lower performance means bad user experience and a lower place in SERP rankings. In this blog post, you will find a tutorial on how to create a custom Wordpress theme and improve your website’s performance.

SmartNICs with P4 support

In the first part of this blogpost we discuss the idea of using smartNIC solutions to optimize network performance in a data center. In the second part, we review the currently available (July 2020) smartNIC solutions that can be programmed with P4. A paradigm of edge-computing has been gaining in popularity of late. The term itself can refer to many sub-technologies and have many meanings. One of them is the existence, next to the centralized, large data center, of those small or very small, located closer to the end-user.

A guide to a UX prototype design

A physical demonstration of your ideas is the best way to check if they really work. For investors, a clickable prototype says more about the product’s business potential than a wordy description. For your clients, user experience is a decisive factor. Read on to see how a UX prototype can help you develop your software product, even those destined for the most complex network systems. In a nutshell, a clickable UX prototype is an interactive version of a product that allows you to show its functionalities and the user’s navigation flow in practice.
