Summary: What is a VPS?

A Virtual Private Server (VPS) is a virtualized server environment that provides dedicated resources on a shared physical infrastructure. Through the use of a hypervisor, a single physical server is partitioned into multiple isolated virtual instances.

Key Benefits at a Glance:

  • Dedicated Resources: Fixed allocations of CPU, RAM, and storage guarantee stable performance, regardless of other users on the host.
  • Full Root Access: Provides maximum flexibility to install custom operating systems and specialized software.
  • Cost-Efficiency: Offers a level of control similar to a dedicated server at a significantly lower price point.
  • Security & Scalability: Logical isolation ensures high data security, while the virtual nature allows for seamless upscaling as your requirements grow.

A VPS serves as the ideal bridge between affordable shared hosting and complex dedicated servers—perfectly suited for web hosting, app development, and enterprise-grade applications.

VPS - simply explained

VPS is the abbreviation for Virtual Private Server (virtual private server). This is a virtual environment that is operated on a physical server - with its own operating system and resources. However, the virtual private server - also known as a vServer - is only one part of a larger physical server, which is divided into several such virtual areas. The physical server is provided by a web hosting or cloud provider.

STACKIT is a powerful European cloud platform that offers companies a European alternative to large US providers such as Amazon Web Services (AWS), Google Cloud or Microsoft Azure. As part of the Schwarz Group, STACKIT places particular emphasis on data sovereignty, data protection and IT security. The entire technical infrastructure is located in certified data centers in Germany and Austria. In this way, STACKIT ensures that all data is stored and processed exclusively within the EU - fully compliant with the General Data Protection Regulation (GDPR).

What are the advantages of VPS with STACKIT?

Data protection

STACKIT provides companies with secure and data protection-compliant cloud infrastructures—with servers in Germany and Austria. This is particularly beneficial for companies that have high requirements for security and data protection.

Flexibility

The virtual servers can be managed—and scaled if necessary—flexibly via a self-service portal or an API. This gives users the ability to control their capacities flexibly and keep costs transparent and manageable.

Security

Modern hardware-based security technologies effectively protect virtual machines from unauthorized access. STACKIT thus offers comprehensive protection and meets strict compliance and regulatory requirements, for example through encryption and extensive access controls.

Consulting

STACKIT can offer customers comprehensive support and personal contacts who can provide quick and expert assistance with technical questions.

Range of services

STACKIT also offers a wide range of managed services such as databases, Kubernetes, and storage solutions that can be easily integrated into the VPS environment.

Efficient use of resources

Thanks to the user-friendly pay-as-you-go model, users only pay for the resources they actually use, which makes cost planning much easier.

What is VPS?

A Virtual Private Server (VPS) is a powerful web hosting solution that offers more flexibility and performance than classic shared hosting. In contrast to shared hosting, where many users share a server with shared IT capacities, with a VPS, dedicated RAM, CPU power and storage space is only available to one user. This allows various tasks and services to be performed reliably. Virtualization creates a separate, isolated environment in which you can manage your system software, applications and network yourself. Developers in particular benefit from this because they have full control and can create their own solutions with special functions and software.

VPS is ideal when high performance is required for data-intensive applications and a lot of storage space or when there is a lot of network traffic. Compared to other hosting plans, vServers offer more stability, security and scalability. You can freely choose the system software, have root access for comprehensive administration and your own IP address.

VPS is therefore a flexible and powerful computing solution that is suitable for numerous web hosting tasks, applications and developer projects. It combines the performance and management options of a dedicated server with the cost benefits of virtual capacity, making VPS particularly suitable for demanding services.

How does a VPS work?

Although a virtual private server shares a physical server with other users, it simulates a dedicated server hosting environment. This works by using a so-called hypervisor that runs directly on the server hardware. The hypervisor divides the physical server into several virtual servers, each of which can run its own operating system and software. This means that these virtual environments are completely separate from each other and function independently.

Even if the underlying technical components are used by several users, resources such as CPU power, RAM and storage space are permanently allocated to each VPS and cannot be shared by other accounts. This means that the performance allocated to you is guaranteed and you only pay for this guaranteed share. This structure ensures that your VPS functions like an independent server - with full control and management.

VPS compared to shared hosting and dedicated servers

Shared Hosting

With shared hosting, several users share a physical server and its resources. However, no fixed amount of resources is guaranteed, which is why the computing power and memory of your website can be affected by the activities of other users.

Dedicated hosting

Dedicated hosting, on the other hand, provides an entire physical server exclusively for one company. All resources - from the underlying technical components to the server software - are reserved exclusively for you. You have complete control over the entire server environment.

VPS-Hosting

VPS hosting is located between these two solutions: Here, your virtual server is allocated a fixed amount of resources compared to shared hosting. At the same time, you benefit from many of the advantages of dedicated hosting, including your own operating system, individual server applications and root access control - and usually at a lower price.

Areas of application for virtual private servers

A VPS is suitable for many different applications that require more performance and control than classic web hosting - without having to invest directly in expensive dedicated hardware. Thanks to the root access rights and the isolated environment, a VPS is very flexible and suitable for various applications:

VPS security - effective protection and risk minimization

The security of a VPS is based on proven cloud security measures that aim to ward off both external and internal threats to corporate security. These include procedures and technologies such as identity and access management (IAM) tools, backup and disaster recovery, firewalls, SSL certificates and secure VPN connections to ensure that data transmission is encrypted and protected.

Frequently asked questions and answers about VPS

What is VPS hosting?

When creating a web application or website, customers often need to set up a database, configure a web server and upload their code. Managing the underlying physical servers is complex and expensive. Hosting providers therefore take over the hardware management and offer VMs instead. With VPS hosting, each user receives their own VM with permanently assigned resources on which applications and websites can be set up and controlled themselves. This allows customers to concentrate fully on their projects without having to worry about the physical server infrastructure.

Is VPS hosting secure?

Yes, VPS hosting is secure. VPS security results from the complete separation of virtual servers from each other. In shared hosting, several users share resources and can therefore be affected by security vulnerabilities of others. With VPS, the resources are isolated and protected from attacks. Security can be increased even further with firewalls, virus protection and other proven measures.

What is a backup?

A backup is a copy of important data, programs and settings from a VPS or computer. A backup stores this information in a safe place so that you can quickly restore it in the event of a system failure, accidental deletion or problems caused by malware.
