Infrastructure as a Service & Infrastructure as Code

Due to its short delivery, installation, and waiting times, SysEleven Stack is particularly suitable for developers and software manufacturers. The code and the templates are the keys with which you define what your setup should look like: You define the dimensions of the environments you need based on your specifications and reproduce them as often as you like with a single command. The stack provides you with the necessary computing power automatically.

To get you started more easily, we offer tutorials in our documentation as well as a selection of proven templates (You can download them for free on Github). These are suitable for various environments like e-commerce projects, development pipelines and content management systems.

If you like, we can assist you creating a setup with OpenStack in a workshop. Get in touch with us!

SysEleven + OpenStack = SysEleven Stack

OpenStack Logo black

OpenStack is the basis of the SysEleven Stack. The open source software is widely regarded as the standard for cloud computing. It is constantly being developed further by an enthusiastic community and promises a high degree of compatibility. For the SysEleven Stack, we have adapted OpenStack to offer our customers an improved platform for more performance and stability.

We deliberately operate our SysEleven Stack with standard APIs and without variations that lead to incompatibilities. This means that there is no vendor lock-in for you and you remain future-proof thanks to the high level of compatibility.

In order to meet the high demands of our customers and to offer a high-quality Infrastructure as a Service, we have added two components to our Stack:

  • For Software Defined Networking (SDN) we use MidoNet from Midokura. This enables us to provide enterprise level support and a range of functions for the SDN.
  • To improve the performance of the Software Defined Storage (SDS), we rely on an enterprise component from Quobyte. It allows high input/output operations per second (IOPS) with maximum data security – the solution always backs up data three times and is directly coupled to user authentication.

Better Safe than Sorry: We operate the SysEleven Stack via two availability zones in our certified data centers located within Berlin, with which you can set up a highly available active-active setup. Since both the data centers and SysEleven GmbH are located in Germany, the strict data protection regulations according to GDPR and the Federal Data Protection Act apply.

Managed Cloud through partners

A large number of agencies, software manufacturers, and service providers use the SysEleven Stack to implement various projects for customers who attach particular importance to cost efficiency and data protection. Our partners take over the management of the SysEleven Stack for you so that you can focus on the further development of your business.
