What is TOSCA?
For automating the Lifecycle Management of application,
network, and infrastructure services.
That defines a Domain-Specific Language (DSL)
TOSCA is an OASIS Standard

TOSCA History and Milestones
▪ TOSCA Version 1.0 Specification approved as an OASIS
Standard
▪ Published in Nov 2013, XML format
▪ Focused on orchestrating application-level services
▪ Focused on portability across multiple clouds
▪ TOSCA Simple Profile v1.0 Specification (YAML format)
▪ First published as an OASIS Standard in 2016
▪ Provided a more human-readable encoding
▪ Included Simple Profile types for rapid development of cloud
applications
▪ Current version: TOSCA Simple Profile v1.3
▪ Mature standard, published in 2020
▪ Adopted by ETSI NFV with the goal of lowering OpEx
associated with managing VNFs and virtual network services
▪ TOSCA Version 2.0 (Planned for Late 2020)

TOSCA is an OASIS Open
Standard
▪ Global, nonprofit member-driven organization
▪ Promotes interoperability, innovation, and freedom of choice
▪ Federation of autonomous working groups
▪ Broad agenda: cloud computing, cybersecurity, privacy,
blockchain, IoT, emergency management, legal…
▪ Member of European Multi-Stakeholder Platform on ICT
Standardization→ EU allows OASIS specs to be referenced in
public procurement.
▪ Liaison relationships offer path to de jure standardization:
ISO, IEC (JTC 1), ITU, ETSI
▪ Home of TOSCA, SAML, PKCS, CAP, OpenDocument, OData,
MQTT…

TOSCA uses Model-Driven
Lifecycle Management
▪ TOSCA assumes a model of deployed service instances
(Service Instance Model)
▪ As context for handling faults and events
▪ As starting point for Moves, Adds, Changes, and
Deletions (MACDs)
