Kubernetes as a Service

Kubernetes simplifies the design of microservice architectures and is used for the simple scaling of applications and clusters. As a specialist in managed services, First Colo offers fully managed Kubernetes clusters. Convince yourself of the benefits of a fully managed environment!

What is Kubernetes?

As an open-source orchestration system, Kubernetes enables the automated operation of so-called containers. It serves as a platform for the provision and operation of certain applications in said containers. Furthermore, Kubernetes manages the complete lifecycle management of the containers and users can determine how applications run and interact.

How can I imagine containers?

As the name suggests, these containers are also a type of bin. In such a container, for instance, an application can be stored together with all its dependencies in isolation. The result is a so-called container image, which retains the full scope of the application while simultaneously maintaining the smallest possible size. Hence, the containerised application can easily be transported and rolled out at different locations. Furthermore, containers need way fewer computing resources than traditional virtual machines and make applications less reliant on the underlying environment.

 

Which adventages does containerisation offer?

Isolation

Various containers are always strictly kept separate from one another. Therefore, a container image never has access to the resources of other containers, which in turn improves the efficiency of the underlying computing resources.

Lightweight

Since a container image does not require any operating system or kernel, it is far more dynamic than other virtual machines and can be transported and installed even faster.

Flexibility

A container image can serve as an architecture model for existing containers. Running applications can use this architecture model to scale even better.

Testing

Should a container not function properly or needs to be updated it can be quickly torn down. If necessary, it can be rebuilt just as quickly. This feature is ideal for test environments.

Location-independence

Since all dependencies of the application also lie in the container, the container image can easily be rolled out everywhere. On-premise deployments can thus be replaced.

Speed

Since each container runs autonomously and as an isolated process, the program runtime is much shorter. The time required for starting and stopping the applications is therefore reduced to a minimum.

 

Why we choose Kubernetes

Applications typically consist of multiple containers, which are distributed across different virtual and physical host systems. Kubernetes helps to manage such a structure by grouping multiple containers into so-called pods, which adds an additional abstraction layer to the environment. This helps to schedule individual workloads and simplifies internal networking and connection to other services such as storage.

In terms of management Kubernetes follows a declarative approach. This means that Kubernetes always displays the desired final state of the system, which is continuously compared with the current state. Subsequently, the necessary steps to achieve the intended final state can be executed automatically.

As an open-source solution, Kubernetes has a very large developer community that takes care of the maintenance and the expansion of the functionalities. In addition, there are numerous integrations and plug-ins, which are compatible with the application architecture. This constantly creates space for new features and the solution is continuously being improved.

Full-Managed Kubernetes – tailored to your business model

Dedicated Kubernetes Cluster

Upon request, we set up a Kubernetes cluster on dedicated servers within our infrastructure. We provide all dedicated servers within a separate area in our data centre, to which only authorised employees have access.

Kubernetes in the private cloud

For smaller environments or test environments customers can get their own resource pool from our internal virtualisation cluster. There is no need for hardware or rack space and the virtual resources can be flexibly extended at any time.

Both solutions foresee that the virtual machines within the Kubernetes cluster are operated in high availability, which offers additional reliability and increased uptime. Therefore, updates to the infrastructure can be carried out easily and without any downtime. The linkage to the storage is based on Ceph. Data is stored threefold and the Ceph cluster offers comprehensive integration options via open interfaces and native support. The uplink capacity of the storage is at least 10 Gbit and the memory itself is 100% SSD-based. All data is processed GDPR compliant in our DIN ISO 27001:2013 certified data centres. To add even more protection, data can also be backed up off-site. In any case, however, the data will never leave Frankfurt am Main.

We would be happy to consult you regarding the choice of the solution. Certainly, we will find the infrastructure that best suits your needs.
Focus on your core business and let us take over the management of your Kubernetes cluster!
