Apache CloudStack vs Kubermatic Kubernetes Platform

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

Kubermatic Kubernetes Platform (KKP) automates Kubernetes cluster deployment, scaling, and lifecycle management across hybrid cloud, multi-cloud, on-premises, and edge environments. Its customer-managed control plane can manage thousands of clusters across more than 20 public cloud providers and on-premises environments. Development teams can provision and deploy environments through a self-service portal. KKP supports cluster upgrades and rollbacks, plus an add-on controller for software, configuration, and policy. KubeVirt support brings virtual machines and containerized workloads into one interface. Security controls include multi-tenancy, role-based access, cluster authentication and authorization, and policy blueprints and presets. Prometheus, Grafana, and Loki have native support; teams can also connect CI/CD systems, Terraform providers, or Ansible playbooks. KKP is self-hosted and installed with the Kubermatic Installer, and requires a Kubernetes master cluster. Community Edition costs nothing under Apache License 2.0. Enterprise Edition has no listed price and bills worker-node vCPU and memory on a consumption basis; master cluster nodes are excluded.
