Kubernetes (K8s) is a leading container orchestrator that automates key tasks such as deployment, scaling, and fault tolerance in production environments. There are various distributions of K8s available, including the lightweight option K3s, which is suitable for resource-constrained IoT and edge computing scenarios. While K3s is smaller and simpler than standard K8s, it maintains compatibility with all Kubernetes features. The choice between K3s and K8s depends on deployment needs and resource availability, with K3s being ideal for smaller setups and K8s being more suitable for large-scale production applications.
