Hot swapping allows servers to be serviced without interruption

In a world where business processes operate continuously and online services are available to users 24/7, the stability of servers becomes one of the key success factors. A website may receive thousands of visitors per day, a CRM system serves managers in real time, and financial transactions take place every second. Under such conditions, even a short downtime can have significant consequences: from halted sales and disrupted internal processes to loss of reputation and customer trust. That is why modern servers are designed to remain operational even during maintenance. One of the technologies enabling this is the ability to hot-swap disks and power supplies.

AI accelerators are becoming the core of modern server infrastructure

The rapid progress of artificial intelligence has forced the data center industry to radically restructure: classical server farms must transform into AI-oriented “supercenters” with supercomputer-level power and new infrastructure requirements. At the core of these changes are specialized AI accelerators — hardware chips designed to speed up machine learning tasks, which have essentially become the foundation of modern data center architecture. Without such accelerators, breakthroughs like ChatGPT would take much more time and money — no wonder AI accelerators are now widely used by global tech giants.

How a Hypervisor Divides a Physical Server into VPS

In Servers

The physical server is divided into several independent VPSs.
Partitioning hardware resources into separate virtual environments

Not so long ago, to launch a website or an online service, it was necessary to rent or purchase a whole physical server. This is expensive, difficult to administer, and comes with excessive capacity that often remains unused. The situation changed with the appearance of virtualization — a technology that allows creating several independent virtual servers on a single physical server. Each of them operates as if it has its own processor, memory, disk space, and operating system. The key element of this process is the hypervisor. It acts as a “conductor” that controls the distribution of resources and ensures the stable operation of each VPS.

Why Free SSL Certificates Are Not Always Suitable for Business

In Security

A man in a suit looks thoughtfully at an image of an SSL certificate marked "FREE."
Which SSL certificate should you choose for your business?

When we talk about website security, the first thing that comes to mind is the SSL certificate. It encrypts the data transmitted between the browser and the server, protecting it from interception. A site with the padlock icon in the address bar appears more trustworthy, which is why many companies use free SSL from Let’s Encrypt and similar providers. However, the question is whether this solution is always suitable for business. In reality, free SSL is a good starting point, but it doesn’t always offer the level of trust, control, and stability required for commercially valuable websites.

Why modern laptops are abandoning coolers and how this affects heating and speed

Not so long ago, fanless laptops seemed like niche devices: they were bought only by those who valued absolute silence rather than speed. It was believed that passive cooling could not cope with the heat generated by the processor, which meant that the performance of such laptops would be low. However, in recent years the situation has changed dramatically. The market has seen models that combine silence, compactness, and enough power for everyday tasks. This is not just a trend, but the result of significant changes in the approach to hardware design and processor architectures.

How Microsoft and Google Compete in the AI Assistant Space

Two people in business suits shake hands, their heads replaced by the Microsoft and Google logos, with an "AI" icon between them.
The race of tech giants for leadership in artificial intelligence

Just a few years ago, artificial intelligence was perceived as an auxiliary tool, something like a voice assistant on a smartphone that could set a timer or answer a simple question. But large language models changed everything. New AI systems emerged that can analyze, summarize, create text, generate ideas, structure knowledge, and help interact with information on a much deeper level. Against this backdrop, a major competition began between Microsoft and Google—two companies striving to shape how we will work with information in the future. Their AI assistants—Copilot and Gemini—are now seen not as optional features but as a new interface layer between humans and computers.

Backup power ensures continuous data center operation even during a blackout

When we open a website, place an order in an online store, or work with a corporate CRM, we rarely think about what’s happening “behind the scenes.” Yet even a few minutes of server downtime can cause serious losses — from losing customers to damaging databases. That’s why every professional data center is built on one principle: to operate continuously, no matter the circumstances.
