Kubernetes vs KubeSphere

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It supports stateless, stateful, and data-processing workloads, and can run locally, in a cloud, or in a datacenter; users can also choose a managed service rather than operate a cluster themselves. It coordinates gradual updates while monitoring application health and can roll back a change if something goes wrong. Pods receive IP addresses and groups of Pods can share a DNS name, with load balancing across them. Kubernetes can mount storage from local, public-cloud, or network systems such as iSCSI or NFS. Secrets and configuration can be updated without rebuilding images. Scaling can be manual or automatic based on CPU use. Security mechanisms include Secrets, Pod security standards, RuntimeClasses, network policies, admission controllers, and audit logging. Kubernetes is free, with a listed plan price of free. It does not include application-level services such as databases, message buses, caches, or cluster storage systems.

KubeSphere is a Kubernetes-based platform for managing cloud-native applications, with a plug-in architecture for third-party applications and open-source tools. Its Community Edition is an open-source container platform and costs nothing, with free-forever availability for a self-managed Kubernetes platform. The platform supports multi-tenancy and multi-cluster management, with monitoring, event and audit-log queries, tenant log collection, alerting and notifications. Delivery features include Jenkins-based CI/CD and automated Source-to-Image and Binary-to-Image workflows. KubeSphere supports online or offline installation, one-click upgrades and cluster scaling across infrastructure environments. Its REST API backend includes an API server and controller manager. Enterprise adds image security hardening, two-factor authentication, vulnerability fixes and permission controls at platform, cluster and application levels. Enterprise is available by on-demand subscription or private deployment, with extensions available by subscription; pricing is available from sales. Its lightweight architecture can run with 2 CPU cores and 4 GB of memory.
