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.
(source: https://coreos.com/releases/)
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.
A customer approached us to help them build their new IaaS platform.
We helped him to evaluate the current situation and worked out a concept together with the customer from the selection of the location, the necessary hardware to the operation and implemented it together within a month.
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:
When moving a customer’s onpremise data centre to the public cloud, we were commissioned to plan the Ceph clusters for the Microsoft Azure environment for use with Microsoft Azure AKS. After an intensive testing and optimisation phase, we put the Ceph clusters into production there and took over the migration to the Microsoft Azure AKS offering.
Since 2021, we have supported one of our customers in the architecture and operation of more than 150 Kubernetes clusters with Ceph worldwide in all hyperscalers, such as GCP, AWS, Microsoft Azure and AliCloud.
Use of programming languages to define customised infrastructure environments using Terraform. Use of language constructs and tools that follow Infrastructure as Code (IoC) design patterns.
Use of functions and libraries within programming languages to develop complex infrastructure projects.
Use programming languages such as TypeScript, Python and Go to map multi-cloud environments. With the modular and open architecture to include hundreds of vendors and thousands of module definitions.
After more than 10 years of experience with different evolutionary stages of timeseries monitoring systems and the growing need for metrics, we decided to replace database and file based solutions.
To store metrics for the long term, we rely on object storage technology to provide almost unlimited storage capacity in the backend.
The Object Storage is provided to us by multiple Ceph clusters. We are now also able to dynamically connect alternative storage locations, such as AWS and/or GCP, as needed.
