In your datacenter? In the cloud? Or anywhere in between?


On premises



Stay in full control

Especially sensitive information, such as personal data, must be managed on dedicated servers.

With our on-premises hosting, you stay fully in control of your servers in your own offices. Our experts come to you to consult you personally. Based on extensive analyses, we can optimally manage your systems and uncover potential for improvement. Through tailored adjustments, we can perfectly align your system landscape with your requirements, and create a harmonious system.

We take care of your infrastructure

With platform as a service (PaaS), you can forget about the setting up of a complex IT infrastructure, and simply use your resources in the cloud.

Benefit from transparent prices and top quality security in accordance with German data protection law. Thanks to our comprehensive security concept, you can always access your data. Save high infrastructure and software costs and use your storage space differently.

We take care of maintenance, updates, data backups, and more, making sure that all your systems are up to date at all times, and that you can fully concentrate on your projects.

With our platform as a service offer, long waiting times are a concern of the past. We quickly provide your with the required hardware and software, ensuring that you can access your data and collaborate from anywhere.





Comfortably use your software in the cloud

With our software as a service (SaaS) offer, we provide you with the entire application and required infrastructure. We take on the responsibility for all areas, such as data, storage, and applications.

With a cloud-based software, you secure a huge competitive advantage and better support your customers, as they will not have to align their infrastructure to a new software but can work flexibly in the cloud.

A cloud-based software is very attractive for your customers. It means they always enjoy the latest version of your software and do not need to operate it locally, which guarantees that everything is always up to date.

You are awaiting a new launch, move to a new location, or simply wish to work with your software on the go? We make your software ready for the cloud to get you started right away.

Gain the right amount of capacity and storage space with the cloud

You are affected by seasonal business or require more capacity upon short notice? With our infrastructure as a service (IaaS) model, you can adapt your resources to your demands. You benefit from highest-level scalability and flexibility.

Simply select your desired hardware components by well-known manufacturers – we take care of the rest, such as the management of your top modern infrastructure.

Through IaaS, you can slim down your IT infrastructure and thereby reduce costs. You save expensive investments for your own IT infrastructure, and gain the storage space necessary for the operation of your applications, as well as the full power of the cloud.

We happily consult you and help you find the right solution for you.
