Network monitoring challenges in heterogeneous environments

The growing complexity of network environments poses great challenges to effective network monitoring. This should come as no surprise: such environments can include bare metals (on-prem solutions), data centers, private and public clouds. Additionally, automation, orchestration and SDNs can greatly enhance your network management, but at the same time add yet another level of complexity. In this blog post, we will discuss the main challenges related to monitoring and how to solve them to streamline the entire monitoring process.

P4-programmable smartNIC controlled by ONOS (video)

The traditional NIC (Network Interface Card) is a relatively simple device equipped with Ethernet interface(s) and used to enable connectivity between machines. SmartNICs, by contrast, offer much more sophisticated capabilities and allow you to perform advanced operations on packets. SmartNICs are thus perfectly suited to optimize network performance in a data center, especially those that are programmable and offer the computing resources required.

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.

User experience in network systems: dos and don’ts

Developing complex network systems dedicated to network professionals is a huge challenge. Well-designed software will make your everyday work faster, easier and more enjoyable. An outdated UX design, on the other hand, can significantly decrease your productivity and result in errors when you’re using the system. If you are planning UX strategy for your product, read our blog post to see what guidelines you should follow. They’ll help you provide the best user experience in network applications and also avoid errors.

P4 Network Programming Language — what is it all about?

The programming language P4 is gaining in popularity in the network industry and is considered the next step in the SDN evolution. In this blog post, I will take a closer look at P4 and try to show why it is so important. Network devices like switches or routers are most commonly designed ”bottom-up.” The switch vendors that offer products to their clients usually rely on external chips from 3rd party silicon vendors. The chip is the heart of the system and in practice determines how device OS is realized and what functionality it can offer.

UX principles for complex network applications

Every application has essential elements that together lead to great user experience. Information-heavy network applications are no exception here. Yet in many cases their usability is poor due to technological debt or lack of UX expertise during the design phase. In this blog post I will highlight UX best practices in designing applications for network monitoring that will enhance user experience. The very first thing a user appreciates in an app is its smooth navigation, the real backbone of sound user experience.

A traffic generator for measuring network performance

It is probably the cloud that first comes to mind when you think about the architecture of modern services. It is an obvious choice for building large, distributed systems from scratch, as well as for the many enterprises migrating their infrastructure and services to the cloud. It is all very appealing, and modern, and intelligent. But that does not mean there are not serious challenges in going cloud. How should the infrastructure in use be tested? How can network performance be measured reliably in a cloud environment?
