ystia/yorc repository overview

⁠Ystia Orchestrator

Yorc is an hybrid cloud/HPC TOSCA⁠ orchestrator.

It aims to support the whole application lifecycle, from deployment, scaling, monitoring, self-healing, self-scaling to application upgrade, over hybrid infrastructures (IaaS, HPC schedulers, CaaS).

Yorc is TOSCA native to allow handling complex applications in a standard way. Yorc is also workflow-driven, this means that it doesn't contain any hard-coded lifecycle logic. This allows to fully customize applications behavior and to execute custom workflows at runtime.

Yorc is designed for large-scale, it is built with a tasks / stateless workers model in mind allowing to scale it horizontally easily.

Finally, while you can easily interact with Yorc directly thanks to its comprehensive REST API and a modern CLI, the recommended way to use Yorc is to model your applications in a powerful TOSCA designer called alien4cloud⁠ and to use it to deploy and interact with your application at runtime. To do it we developed an Alien4Cloud plugin for Yorc⁠
