068 | Internet Link Redundancy (for Web Services and Data Centers)

July 30, 2025

We conclude our series on communication link redundancy by exploring perhaps the most critical scenario for modern companies: ensuring continuous Internet access for web services, applications, and data centers. If your website, online store, cloud services, or APIs become unreachable to the outside world, the consequences are immediate — lost customers, lost revenue, and reputational damage.

Providing resilience at this level is complex but absolutely essential, requiring deep understanding of network protocols and architectures.

065 | Why Network Resilience Is Not a Luxury, but a Necessity

In today’s world, where every aspect of business depends on IT, and downtime is measured not only in lost revenue but also in missed opportunities and reputational damage, connection stability becomes a critically important factor. From email and internal CRMs to online sales and cloud services — all of it requires constant and reliable network access.

This is where network link redundancy comes into play. It’s not just “insurance” — it’s a fundamental part of your business continuity and high availability strategy for your IT infrastructure.

029 | Proxy Servers in Action: HAProxy — High-Performance Load Balancer⚡️🔗

In our series of articles on proxy servers, we’ve already discussed Nginx, a versatile tool combining the roles of a web server and a reverse proxy. Today, we’ll take a look at HAProxy (High Availability Proxy) — a specialized solution focused on a single but extremely important task: high-performance load balancing and ensuring high availability.

What is HAProxy?

HAProxy is free, open-source software that acts as a load balancer and reverse proxy for both TCP and HTTP protocols. It is designed to handle very large volumes of simultaneous connections and is a key component for building highly available and scalable web applications and services. HAProxy is often used as the “brain” in front of a group of servers, distributing incoming traffic among them.
