Today, Kubernetes is the first choice for running microservices in the public or private cloud. More and more developers and enterprises are building their applications on the modern microservice architecture.

Many of them are using Kubernetes for automated deployment of their workloads and want to benefit from the new flexibility and robustness. We are working on a solution for our customers to simplify and unify Day One and Day Two operations in their operations. With the increasing number of clusters, the management, updating and monitoring should be able to deal with it efficiently.

Since 2018, we have been accompanying in its development and had direct exchanges with various members of the project at Cephalocon in Beijing 2018 and Barcelona 2019.

In 2019, we began serving customers in production who use to manage Ceph.

Storage Operators for Kubernetes

Rook transforms distributed storage systems into self-managing, self-scaling and self-healing storage services. It automates the tasks of a storage administrator: provisioning, bootstrapping, configuring, deploying, scaling, upgrading, migrating, disaster recovery, monitoring, and resource management. Rook leverages the power of the Kubernetes platform to deliver its services to any storage provider through a Kubernetes operator.


Since 2020, we are now working on improving the automated operation of Ceph with Furthermore, it is planned to have the platform fully audited by various certification bodies.

At the request of a customer, we were asked to adapt the performance and capacity of their existing Ceph cluster to the growth in ongoing production.

As a result, without maintenance windows and without service interruption, we have increased the Ceph cluster by 3700% during operation.

After the acquisition of CoreOS by RedHat and the discontinuation of CoreOS support.

CoreOS Container Linux will reach its end of life on May 26, 2020 and will no longer receive updates.

We have decided together with our customer to provide an alternative to CoreOS before the 26.05.2020.

The current project name is Gardenlinux, although the name may not change until the public release.

Gardenlinux builds a full replacement for CoreOS based on Debian, without being biased by a target architecture.

Currently, the project supports the following platforms: BareMetal, AWS, GCP, Azure, VMWare, Openstack, and KVM and Docker.

Ports for AlibabaCloud are still under development.

In Produkton, Gardenlinux has already proven itself on BareMetal, KVM and AWS.

Even though microservices with Kubernetes are gaining traction in the cloud environment, we still have a high demand to serve for managing virtual machines.

To keep the technology stack as lean as possible, we are phasing out our Cloud Controller environments and managing Virtual Machines using Kubernetes.

In a further step, we are thereby able to use Kubernetes to map complete environments with microservices and virtual machines through one technology.

On behalf of the customer, we provided the optimal Kubernetes platform for ONAP as a managed service.

ONAP is a comprehensive platform for orchestration, management, and automation of network and edge computing services for network operators,

cloud providers, and enterprises. Real-time, policy-driven orchestration and automation of physical and virtual network functions enables rapid automation of new services and complete lifecycle management critical for 5G and next-generation networks.

For a client, we are developing a unified interface/service to manage Virtual Machines and Containers for the Private Cloud with Kubernetes, Openstack, CloudStack, Opennebula, VMWare vSphere and Hyperscalers, such as GCP, AWS and Azure.

We are currently focusing on the following advantages:

  • Centralised management of distributed resources
  • Evaluation of costs across different providers
  • Reconciliation and implementation of planning
  • Mitigation of cloud provider failures
  • Connection of egde computing
  • Connection of sites
