Cloud orchestration is no longer a wild-west of proprietary solutions. The enterprise and NFV industries are moving towards standards compliance with efforts focused on the OASIS TOSCA standard, which offers a policy-driven YAML-based language to design flexible and extensible cloud topologies, comprising compute nodes (VMs and containers), VNFs (Virtual Network Functions), as well as user-defined node types. This talk will introduce the Apache AriaTosca project, a compliant TOSCA parser and orchestrator. As well as being a fully functional orchestrator in itself, AriaTosca serves as a platform and SDK for building TOSCA-based solutions in Apache and beyond.
