Introduction to Docker on a Managed VPS

Docker sits at the heart of scalable enterprise hosting. From KVM-backed VPS to high-availability clusters, Zen Hosting integrates enterprise Docker hosting and managed support designed for serious workloads.

Whether you’re running microservices, development pipelines or SaaS environments, Docker simplifies container management, helping you deploy, scale and isolate applications efficiently from a managed VPS.

As of 2025, Docker in enterprise hosting lets you build smarter, scalable VPS platforms.

What is Docker?

Docker is a powerful platform that uses containerisation technology to make it easier to create, deploy and run applications.

A container is like a lightweight, standalone package that includes everything needed to run a piece of software: code, runtime, system tools, libraries and settings.

Containers are isolated from each other and the host system, ensuring consistent operation across various environments.

Why Use Docker on a Managed VPS?

Using Docker on a Managed VPS offers a range of benefits for developers and businesses:

Efficiency: Docker containers use less disk space and memory than traditional virtual machines, as they share the host system’s kernel rather than requiring their own operating system. This efficiency leads to more effective utilisation of system resources.

Consistency: Docker ensures that applications run consistently across different environments by packaging the application and its dependencies into a Docker container. This eliminates the “it works on my machine” problem, making developers’ lives easier and improving overall container management.

Isolation: Containers are isolated from each other and the host system. This isolation reduces the risk of security vulnerabilities affecting the entire system and prevents software conflicts between applications running on the same server.

Scalability: With Docker, scaling your application horizontally (adding more instances) is as simple as starting new containers. This scalability is essential for applications that experience varying loads.

Seamless Updates: Docker facilitates easy updates and rollbacks of software versions within containers without disrupting the entire system.

Examples of Docker in Action

Docker’s versatility shines in many practical scenarios.

Some real-world applications where Docker significantly enhances efficiency and functionality include:

Web Development: Host multiple websites on a single VPS, each within its container, ensuring they don’t interfere with each other.

Application Testing: Test applications in different environments by quickly setting up and tearing down containers.

Database Management: Run different database versions for various projects without any conflicts.

Load Balancing and High Availability: Use Docker to create replicated clusters of services or applications, or integrate with a Proxmox cluster to achieve high availability and streamlined failover.

Big Data Processing and Analytics: Run big data applications and analytics tools within Docker containers for scalable and efficient data processing.

Getting Started with Docker on Your Managed VPS

Docker works on Windows and quite a few Linux distributions.

For Linux VPS:

Operating System: Docker requires a 64-bit version of a Linux distribution, such as Ubuntu, CentOS or Debian.

Kernel Version: Docker generally works with Linux kernel version 3.10 or newer.

RAM: A minimum of 2GB is recommended, although more may be required based on container usage.

Disk Space: The requirement depends on the Docker version and the applications you plan to run.

For Windows VPS:

Operating System: Windows Server 2016 or later for Docker Engine – Enterprise; Windows 10 64-bit: Pro, Enterprise, or Education for Docker Desktop.

CPU: A 64-bit processor.

RAM: At least 2GB, more recommended for better performance.

Disk Space: Varies depending on the Docker version and your usage, but 32GB is a good starting point.

Additional: BIOS-level hardware virtualization support must be enabled. For WSL 2 backend, specific versions of Windows 10 are required.

For Both:

Administrative Access: Docker installation requires administrative or root access.

Integration Note: For enterprises already running virtualisation stacks such as a Proxmox cluster, Docker integrates cleanly through lightweight containers that complement existing VMs.
