SD-WAN and SASE both build on traditional network models, such as those used to connect a company’s offices. While the two models share some features and advantages, they have different structures and approaches. In the simplest terms, an SD-WAN inspects and routes data more efficiently, while a SASE combines networking and security functions into a single service. Here’s what you need to know.

IPv6 was developed in the late 1990s as a successor to IPv4 in response to widespread concerns about the growth of the Internet and its potential impact on the existing IPv4 address protocol, in particular potential address exhaustion. It was assumed that after some time as a dual-stack solution, we would phase out IPv4 entirely. Almost twenty-five years later, however, we are approaching full-scale depletion of IPv4 addresses, in part because the adoption of IPv6 is still lagging.

HAProxy Technologies attended Kubernetes Community Days France 2023, where 800 participants gathered to discuss cloud-native and DevOps technologies. It’s always a delight to interact with the heart of the industry and hear how professionals and hobbyists are implementing HAProxy as an ingress controller, load balancer, API gateway, and security solution. If we summarized KCD France 2023 in one word, it would be “community.”

Have you ever wondered how the internet manages to translate the domain names you type into the browser into IP addresses that connect you to your desired websites? The answer lies in the Domain Name System (DNS), a complex network of servers and protocols that makes online communication possible. But with this complexity comes the need for DNS monitoring, which plays a crucial role in ensuring website availability, preventing security breaches, and optimizing network performance.

Have you ever found yourself staring at your screen, waiting for a webpage to load, or a file to download, only to be left frustrated by sluggish Internet speeds? It's like being stuck in a traffic jam during rush hour, with no end in sight. But instead of honking your horn and yelling at other drivers, you might be wondering what's causing the holdup. Well, fear not, fellow internet user, because the culprit might just be network congestion.

Welcome to 2023! As we transition from 2022 — which in many ways was exciting for undesirable reasons such as the lingering pandemic, conflict in Ukraine, and uncertain economic conditions — I am eager to look ahead to anticipate themes that will affect IT or, more specifically, IT Operations. As vendors, customers, and practitioners, we’ve worked in IT through many eras of disruption.

In the world of business, time is money. So when your network is running slower than a sloth on a rainy day, it's not just frustrating - it can be costly. From sluggish downloads and uploads to frustratingly slow web browsing, network slowness can bring even the most productive team to a grinding halt. But fear not! With a little know-how, you can troubleshoot network slowness and speed things up like a pro.

What does it mean to build a successful networking team? Is it hiring a team of CCIEs? Is it making sure candidates know public cloud inside and out? Or maybe it’s making sure candidates have only the most sophisticated project experience on their resume. In this post, we’ll discuss what a successful networking team looks like and what characteristics we should look for in candidates. What does it mean to build a successful networking team?

As I’ve discussed in my previous blogs in this series, smart networks are becoming increasingly important in an ever-increasing range of industries. These smart networks can deliver significant benefits, but there are some risks, challenges and issues associated with moving to “smart”. In my final blog in the series I will discuss what is required from a modernized communications network to counter some of these risk, challenges and issues.

The tech world has been on a rollercoaster since the COVID-19 pandemic. During the large-scale shift to remote work throughout 2020-21, big tech firms invested heavily in talent and infrastructure and there was plenty of growth in the IT space. Since the second half of 2022, however, high inflation, big tech layoffs, and the threat of an economic recession have organizations focused more on remaining cost-effective than investing in growth.
