Apache CloudStack Alternatives for Self-Hosted

OpenStack is an IaaS (Infrastructure-as-a-Service) and cloud computing platform developed by the OpenStack Foundation. The project was first started in 2010 as a joint venture by Rackspace Hosting and NASA. OpenStack both free and open-source and allows you to create public or private clouds with distributed virtual servers. The OpenStack dashboard can be used by administrators of the cloud to empower user, provision resources and track the overall health of the network and infrastructure.

Dokku is a free and open-source project that helps you build and manage the lifecycle of applications. With Dokku developers can setup their own PaaS (Platform-as-a-Service) in a matter of minutes. Dokku provides extra plugins which can be used to manage database, and tools needed for your application. If you need to server your application over HTTPS, Dokku got you covered as well, with the help of Let's Encrypts free TLS certificates.

Swarmlet is a free and open-source, self-hosted Platform as a Service that runs on any single server. It's mainly intended for use with multiple servers, a server cluster / swarm. Swarmlet is inspired by Dokku and brings the same simplicity to Docker Swarm. Swarmlet also uses Traefik v2 and Let's Encrypt to provide automatic SSL and load balancing on your apps.
