Modern companies are increasingly adopting automation for software deployment processes. Combining CI/CD and the GitOps approach makes it possible to update infrastructure quickly and without manual intervention. However, the more automation you have, the higher the risks if security is not properly configured.
This is especially critical when an application or infrastructure is deployed on a VPS connected to a public network. In such a scenario, a supply chain attack can lead to full server compromise and leakage of confidential data.

What Is Server Uptime and How It Affects Your Business Profitability

Uptime is a key indicator of server reliability, showing the percentage of time a system operates without interruptions. For example, 99.9% uptime means less than 9 hours of downtime per year. For any online business, this is critical — even minor downtimes can lead to financial losses, reduced conversions, and reputational damage.

Migration of Containerized Applications from Docker to a Server with Kubernetes (k8s)

Docker has become the de facto standard for containerization among developers and DevOps teams. However, as infrastructure needs grow, so does the need for container orchestration, scaling, self-healing, and centralized management. This is where Kubernetes (k8s) comes into play — a powerful system for managing containerized applications.

Modern businesses increasingly adopt microservice architecture using Kubernetes to manage containerized applications. However, as complexity grows, so does the need for a reliable backup system—not only for configurations but also for persistent data. This becomes especially important when the Kubernetes cluster is deployed on a VPS, where the administrator is fully responsible for infrastructure protection.

Infrastructure as Code – Terraform and Ansible for VPS and Server Autodeployment

In Servers, VPS

In today’s world, where speed and flexibility in managing IT infrastructure determine business competitiveness, automation has become a key tool for DevOps teams. One of the most effective approaches is Infrastructure as Code (IaC).

IaC allows you to define infrastructure in the form of code and automatically deploy it in cloud environments, data centers, or on dedicated servers. In this article, we will explore how to use Terraform and Ansible to automate the deployment of VPS and physical servers, and how this approach simplifies infrastructure management and scaling.

Modern tasks in machine learning, artificial intelligence, and computer graphics require enormous computational resources. Traditional CPU‑based servers are no longer always able to efficiently handle large volumes of data and complex algorithms. This is where GPU (Graphics Processing Unit) and VPU (Vision Processing Unit) come into play, significantly accelerating computations. When these technologies are combined with Virtual Private Servers (VPS), you can build a powerful and flexible infrastructure without heavy capital investment.

Database Migration with Zero Downtime. Tools, Strategy, and Rollback Plans

In Hosting, Servers

In today’s digital landscape, even a few minutes of downtime can lead to lost revenue, decreased traffic, and weakened customer trust. This is especially critical for web applications that rely heavily on databases. Therefore, migrating a database with zero downtime is not just a desirable option — it’s a necessity for businesses scaling or upgrading their infrastructure.

In this article, we’ll walk through how to properly plan your database migration, what tools to use, how to ensure failover safety, and how to prepare for potential rollback scenarios if things don’t go as expected.

Monitoring Container Infrastructure — Prometheus + Grafana in Kubernetes on VPS

By Kateryna Reutova

On August 2, 2025

In VPS

Containerization has revolutionized the way applications are deployed, making the process more flexible, scalable, and manageable. Kubernetes, as the leading container orchestration system, has become the standard for running cloud-native services. However, as the number of services and microservices grows, so does the need for efficient monitoring. This is why the combination of Prometheus + Grafana has become the go-to solution for observing infrastructure health.

In this article, we’ll explore how to set up Kubernetes cluster monitoring on a VPS using Prometheus and Grafana, the benefits of this approach, and why it’s essential for maintaining project stability.

Automated Backup Backends – Proxmox, BorgArchive, and rclone for VPS

In Security

Reliable backup is a critical part of any modern IT infrastructure. For VPS owners, physical server administrators, or cloud environment users—where every failure can cost a business money, reputation, or even complete data loss—implementing an automated backup system is not a luxury, but a necessity. In this article, we’ll explore how to build a flexible and reliable backup backend using Proxmox, BorgBackup (BorgArchive), and rclone.

Continuous Integration and Continuous Deployment (CI/CD) is a cornerstone of modern development workflows. It automates code testing, building, and deployment, enabling faster releases, fewer errors, and more stable products. When using a VPS, you gain full control over your infrastructure, making your CI/CD process even more flexible and efficient.
