Multi-Tool for Container orchestration and Cluster Management with Kubernetes
Kubernetes is the orchestration of Container clusters as the De-Facto Standard. Virtually any Container-platform integrated K8s or on the Open-Source-Basis, a separate Distribution. But what makes the project so successful?

Container technology has become established in recent years as an Alternative to the operation of virtual servers. Virtual operating systems, drivers, and system files can cause extreme Overhead, a large part of the available resources is alone, consumed by the virtual machine (VM).
Container most of the operating system to share files with the Server that hosts the Container. As a result, complex data systems can be operated with a relatively low consumption of resources. The functions of complex applications to be distributed across multiple containers – for example, by using the Web Front-End in a Container and Caching Server are running in another Container.
Out of the many containers, a process capable application, but a higher authority is necessary. Kubernetes – short-K8s – has established itself here in addition to “Docker Swarm and Apache Mesos” as the leading platform for the orchestration of containers.
Originally developed by Google platform runs today as an Open-Source project of the Cloud Native Computing Foundation (CNCF). More than 80 vendors – including Microsoft Azure, IBM Cloud, Red hat OpenShift, AWS, and Oracle’s OCI have Kubernetes applications in the Portfolio.
The way Kubernetes
Kubernetes orchestrated so-called “Pods” as the smallest unit. Sub-Pods, the Workload processes running on Nodes (physical or virtual machines in a Cluster). They contain one or more containers. Of the Cluster, its Nodes is controlled by several “Kubernetes Master”. These communicate with the individual Nodes and the current “Kubelets”.
The Kubernetes masters, each an instance of the “etcd”, the Central key-value database for all the Management of the cluster of the important information and the controller Manager and Scheduler, the newly created Pods allocates Nodes to be running. The Controller to monitor and control the Cluster and its components. In addition, the most important Element in Kubernetes runs on the masters of the API Server.
Within Kubernetes various Tools in the orchestration of containers serve. The platform facilitates demand-based scaling of applications, managing dynamic Changes to existing Container-based applications and the optimization of the underlying Hardware.
Kubernetes is extensible and fault tolerant application components can, depending on the needs of new and cross-system moved started. The platform supports the selection of application Frameworks, languages, Monitoring, and logging tools.
Compliance policies to integrate

With the introduction of Kubernetes is the issue of security in addition to basic issues in focus. It is all a matter of how internal Compliance and safety requirements in Kubernetes can be integrated.
A solution that can help with security in the container orchestration, are Policies such as the Network Policies (network policy), or the Pod Security Policies (Pod security policies, PSP). In addition, the Open Policy Agent (OPA) is gaining in importance.
The theme is reinforced in the case of companies that have agile Frameworks such as SAFe in use. Then, the managers, IT Teams are forced to develop the individual Releases for the infrastructure and applications with higher speed and roll out. In terms of safety and Testing must be taken into account in the development process and in the infrastructure of various aspects of the “Shift left”.
Individual items in these areas will be brought in the life-cycle forward, so on the time bar to the left. In order to keep the associated risks from the outset low, should be defined basic safety guidelines at an early stage in the CI/CD Lifecycle of Kubernetes and involved in the process. Otherwise, must be made up in the security topic later in the context of the Release cycles.
Several third-party vendors, such as twist-lock or AquaSec offer security tools for Kubernetes. These include helpful features like the Registry Scanning, or a run-time protection. Other applications, such as HashiCorp Sentinel and the Open Policy Agent (OPA) facilitate the implementation of the “Policy as Code” and allow you to implement tighter security controls as part of the Deployment process.
The degree of automation, reduces costs, and relieves staff
The bottom line is Kubernetes allows for a high degree of automation, allows for a better management, it simplifies the execution of complex operations and this, above all, reliable. This is particularly useful when companies need for rapid deployment of IT services more flexibility in your infrastructure.
The System can help companies to reduce infrastructure costs by providing a Container-based architecture for a Portfolio of large enterprise applications. In addition, Kubernetes uses free resources which can be used elsewhere.
The platform supports IT Teams to manage extremely complex, in numerous containers clustered applications extremely efficient. As a result, the maintenance Container is optimized based applications. An intelligent interface management, Kubernetes, for example, the Service-discovery and helps to communicate containers to each other. Kubernetes arranged Azure, the access to the Storage of different providers such as AWS or Microsoft.

Kubernetes is very good as a Managed Service. The demand of the company then has been growing for some time continuously. Adacor, for example, with its Managed Kubernetes Cluster tailor-made and scalable platforms for the respective customer requirements, depending on the demand in the Public Cloud, Azure or Private Cloud infrastructure. In this variant, enterprise Kubernetes get in a powerful and highly available environment with a personal care and thus access to the Know-how of IT experts, which are the respective customer’s project.
