The CaaS platforms appeared with the spread of container technology. Such a platform is the Kubernetes developed by Google, now an open project, which helps the development, deployment, scaling, and maintenance of containerized applications. There are several features, which are useful for both developers and operators. These are AutoScaling and Self-healing that contribute to the robustness of the application. There are many projects that deal with the extending (distributions) of the Kubernetes, or making the installation easier (installer). The Gardener developed by SAP is an open-source installer, that realize the installation and management of Kubernetes clusters. The architecture of the cluster that can be created is different from the standard structure of Kubernetes, because of this the comparison of the two systems is important.
