What is Kubernetes?
Kubernetes is the leading platform for managing containerized applications. It enables automatic deployment, scaling, and monitoring of containers—whether they run locally, in a private cloud, or in hybrid environments. Businesses benefit from higher availability, efficient resource utilization, and flexible scalability.
With features like automatic load balancing and centralized configuration management, Kubernetes significantly simplifies the operation of complex applications. Especially in microservices architectures, Kubernetes ensures that individual components work together reliably while keeping your IT infrastructure efficient.
Benefits of a Kubernetes Cluster
Kubernetes clusters offer numerous advantages, including:
- Scalability: Containers and pods can be scaled up or down depending on demand. Applications are executed across nodes to optimize resource utilization.
- Automation: Kubernetes handles the automatic deployment, execution, and restarting of containers, saving time and reducing errors from manual deployments.
- Efficiency: Managing replica sets and pods within a cluster maximizes application efficiency. Multiple containers can run simultaneously, improving overall performance.
- Cloud Independence: Kubernetes can run in external cloud services or your own data center. You can choose between Hosted Kubernetes and Managed Kubernetes, depending on how much of the infrastructure you want to manage.

K8s in the Cloud or On-Premises?
Whether in the cloud or on your own data center – a Kubernetes cluster works seamlessly in both scenarios. The choice depends on your operational and financial requirements:
Flexibility Through Open Source Software:
A cloud-based Kubernetes cluster offers maximum flexibility. Containers can be deployed quickly, resources can be allocated individually, and applications can run across multiple sites or data centers as needed. Even in a private cloud on your own infrastructure, Kubernetes enables efficient use of existing servers while ensuring high availability, performance, and scalability.
Data Center:
An on-premise Kubernetes cluster in your own data center (e.g., on Happyware servers) provides full data sovereignty and customizable configurations. You maintain control over servers, networking, and security policies. This option is often essential for sensitive sectors such as healthcare, finance, or public administration.
Deploying Kubernetes Clusters – Step-by-Step Guide
Below, we outline the step-by-step process for deploying Kubernetes clusters and highlight key considerations to ensure a smooth setup:
- Create the Cluster: Use kubeadm to install the control plane on the master (control-plane) nodes. This includes essential components such as kube-apiserver, controller-manager, scheduler, and the etcd database.
- Add Worker Nodes: Add new worker nodes that run pods and are managed by the control plane using the command
kubeadm join <Master-IP>:6443 --token... --discovery-token-ca-cert-hash.... - Deploy Pods: Containerized applications are grouped into pods and distributed across nodes using Deployments or ReplicaSets. Execution is handled by the kubelet and the container runtime (e.g., containerd or CRI-O).
- Set Up Networking: A CNI (Container Network Interface) plugin such as Calico, Flannel, or Cilium ensures seamless communication between pods and services. The CNI automatically manages IP addresses, routing, and network policies.
- Monitoring & Scaling: Use tools like Prometheus and Grafana to monitor cluster performance. Scaling can be automated with Horizontal Pod Autoscaler (HPA), Cluster Autoscaler, or Vertical Pod Autoscaler (VPA) to efficiently handle workload changes.
| Tip: Utilize kubectl and Kubernetes dashboards to centrally manage your cluster and monitor applications efficiently. |
Kubernetes: Best Practices for Developers & Administrators
Running a Kubernetes cluster is just the beginning. To unlock its full potential and ensure stable operations, keep the following best practices in mind:
- Define Resource Limits & Requests: Assign specific CPU and memory requests and limits to your pods and containers. This helps the scheduler place workloads efficiently and prevents a single application from overloading a node.
- Use Readiness & Liveness Probes: Configure health checks to ensure that traffic is routed only to healthy containers and that failing containers are automatically restarted.
- Implement Role-Based Access Control (RBAC): Grant permissions according to the principle of least privilege to enhance security within the cluster.
- Implement Monitoring & Logging: Leverage tools like Prometheus for monitoring and the ELK stack (Elasticsearch, Logstash, Kibana) for centralized logging to maintain full visibility into the state of your cluster and applications at all times.
