VPS is often perceived as a “clean” server where all resources are available only to a specific website or application. The user expects that if nothing unnecessary is running, the CPU, memory, and disk will be used minimally. In reality, even in a state of relative idle, a server is never completely empty. Dozens of processes constantly run in the background, invisible at first glance, but it is precisely they that gradually consume VPS resources.
For most users, an SSL certificate is just a “padlock” in the browser that indicates a website can be trusted. In reality, behind this padlock lies a complex technical mechanism that encrypts data between the user’s browser and the server. An SSL certificate confirms the authenticity of a website and protects the transmission of passwords, forms, payment information, and any other data. That is why keeping it valid is critically important. When the expiration date of a certificate approaches or the website’s parameters change, the owner faces two actions that may seem similar at first glance — renewal and reissue. Although these terms are often used as synonyms, in practice they refer to different processes with different consequences.
A data center is a specialized facility or a complex of buildings where servers, networking equipment, and data storage systems are located. This is where websites, online services, cloud platforms, and internal corporate systems operate. To ensure uninterrupted operation, data centers are equipped with backup power supplies, cooling systems, fire suppression, and physical security. At first glance, all data centers may seem similar, but in terms of purpose and usage model they differ significantly. Most often, the distinction is made between commercial and corporate data centers, which perform different tasks and are built according to different principles.
Just a few years ago, automation was primarily associated with factories, assembly lines, and physical labor. It was believed that intellectual professions related to analysis, writing, law, or management would remain an area of human advantage. However, the rapid development of artificial intelligence has changed this logic. Today, it is precisely the segment of the labor market that was long considered the most protected that has come under pressure — work based on knowledge, experience, and information processing.
For many years, RAM remained a relatively affordable and predictable component of computer technology. Performance growth was accompanied by declining costs, and increasing the amount of RAM was considered a simple way to scale almost any project. However, today this model is rapidly collapsing. The world is entering an era in which RAM becomes a scarce resource, and its price and availability are determined by global infrastructure projects.
Just a few decades ago, the main sources of information were books, newspapers, and television. Today, a person is constantly immersed in a digital stream: messages in messengers, social media feeds, work chats, push notifications, news, videos, and advertising accompany us almost continuously. This state is called digital overload — a situation in which the volume of information exceeds the brain’s ability to process it calmly. It is important to understand that this is not about “unnecessary” information, but about its constant availability and rapid смена, which leaves no time for reflection.
The world of digital content is changing faster than ever, and image generation has become one of the key technologies driving this transformation. Just a few years ago, AI-generated images looked like an interesting but quality-limited experimental feature. Today, they are evolving into a full-fledged professional tool. Another major step in this direction is the launch of ChatGPT Images — a new image generator from OpenAI that is already being called the company’s most powerful solution in the visual domain.
In today’s digital world, data has become one of the most valuable resources. Photos, documents, websites, customer databases, accounting records — all of this is stored electronically and requires protection. When it comes to data security, two terms are mentioned most often: backup and replication. For many users, they sound similar because both involve copying information. However, in practice these are different approaches that solve different problems. Understanding this difference is important not only for system administrators, but also for website owners, businesses, and anyone who stores important data.
Artificial intelligence has gradually ceased to be an experimental technology and has become part of everyday business practice. Today, AI is used for big data analytics, process automation, forecasting, and language and image processing. All of this creates new requirements for server infrastructure. If previously the main focus was on stability and data storage, now performance, scalability, and the ability to handle constantly growing workloads play a key role. It is in this context that IBM introduced Power11 — a new generation of servers designed to operate in the conditions of the AI reality.
When a website, mail server, or API runs on a VPS, it receives its own IP address — a unique numerical identifier on the network. For internet services, this address has its own reputation, similar to a company’s business reputation. IP reputation is formed based on the server’s behavior: what requests it sends, which services run on it, and whether spam, phishing, or other suspicious activity is detected from it. A poor IP reputation can result in emails not reaching recipients, websites being blocked by browsers, and external services refusing to work with it.
