Open–Source Cloud Computing™
Apache CloudStack™ is an open-source software system designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.
Apache CloudStack Infrastructure for Virtual Machines and Bare Metal
Apache CloudStack is open-source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (laaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.
CloudStack is a turnkey solution that includes the entire “stack” of features most organizations want with an laaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI).
Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured RESTful API. In addition, CloudStack provides an API that’s compatible with AWS EC2 and S3 for organizations that wish to deploy hybrid clouds.

Kubernetes CAPC/CKS
CAPI implementation CAPC integrates Kubernetes with CloudStack simplifying cluster management. Apache 2 licensed, CNCF-managed for hybrid deployments.
CKS is an easy to use quick start integration with kubernetes for starting clusters easily.
CloudStack Solves Key Challenges for Cloud Builders and IaaS Providers
CloudStack can manage tens of thousands of physical servers installed in geographically distributed data centers. It is a powerful laaS management solution, but it is still easy to use and implement with a small team. Powered by a solid open-source community, Apache CloudStack eliminates the dependencies and allows you to follow your own cloud development plan, and use the hardware and software of your choice and business requirements.
Run a Multi-hypervisor Environment at Scale
CloudStack is hypervisor agnostic, supporting VMware, KVM, XenServer and Xen Cloud Platform. This gives CloudStack a unique position in the market: it is not proprietary technology and is not tied to any specific infrastructure.
