Webinar Series

Topology and Orchestration Specification for Cloud Applications (TOSCA) enables users to manage the entire lifecycle of application and network services, from initial service design through service deployment all the way to ongoing service management. TOSCA is widely used and vendor independent. It works across multiple clouds and network technologies, which allows architects to focus on application design and requirements without being bogged down by the ever-changing specificity of the infrastructure.

The OASIS Open TOSCA technical development team brings you this unique opportunity to learn how TOSCA is used for real-world application and deployment scenarios. Leading developers and users of TOSCA have agreed to share their experiences with the broader community during a 2021 webinar series. They will show demonstrations of TOSCA-based systems and examples of TOSCA service templates. They’ll also explain the unique benefits of TOSCA for their application domains. The series will span over 6 months featuring monthly implementation stories leading up to the release of TOSCA 2.0, which has improved the standard to further align it with modern development paradigms, including cloud-native and microservices.

TOSCA is developed under the OASIS Open Consortium. Members include Cisco, Fujitsu, Hewlett Packard Enterprise (HPE), Huawei, IBM, NEC Corporation, NetApp, NetCracker, U.S. NIST, Red Hat, SAP and many more. For more on TOSCA, visit the website.

Who should attend?

This series of events are suitable for network operators, service providers, cloud brokers, application providers, tooling providers, and so on.

Series schedule

The OASIS Open TOSCA leaders are proud to bring you this informative webinar series designed to explain the different facets of TOSCA through real-world implementations.
Take-aways include a clear understanding of:   

  • WHAT it is used for,
  • WHY it is important,
  • HOW to find helpful implementation resources, and
  • WHERE you can get started on your implementation!

Recorded Implementation Stories


First Real-World Application and Deployment Scenario

Turandot: A Lightweight Open-Source Orchestrator That Enables TOSCA for Kubernetes
Guest Speaker: Tal Liron, Principal Software Engineer, Red Hat

At its most basic level, Turandot functions as a replacement for Helm. Service designers can use the expressivity and strict validation of TOSCA to create deployments, pods, services, and even KubeVirt virtual machines, to package them as CSAR files and publish them directly to a live cluster. But TOSCA goes beyond Kubernetes manifests in that it allows designers to create their own node types that model higher-level architecture and other custom systems, and then to add the crucial topologies that relate resources to each other (e.g. a service mesh).

Furthermore, Turandot supports some advanced TOSCA features: 1) container and virtual machine images can be packed into a CSAR file as TOSCA artifacts, which Turandot will then publish to a registry (via Reposure), allowing for entirely self-contained workloads; 2) scripts and other executables can also be packaged as TOSCA artifacts, which Turandot will then deploy to containers or virtual machines and execute as TOSCA interfaces and operations; and finally 3) service composition via policy-based TOSCA node substitution, with support for multi-cluster composition through delegation.

On the todo list are: native support for Argo cloud-native workflows; native NETCONF operations via Candice; Ansible playbooks, and more.

Second Real-World Application and Deployment Scenario
Inter-Cloud Computing: How TOSCA Helps Open Telekom Cloud Users Run Anywhere
Guest Speakers: Dr. Tri Vo, Cloud Architect at T-Systems and Alexander Navratil, Chapterlead Architect at T-Systems

Inter-Cloud computing has been defined as a cloud model that, to guarantee service quality, allows on-demand resources and transfer of workload through interworking of different cloud providers. However, despite the data centre outages in the past, none of the leading commercial cloud providers voluntarily interconnect their infrastructures to allow sharing of on-demand resources among each other. As a result, cloud applications are directly responsible for managing resources provisioning and scheduling. On the other hand, Open Telekom Cloud by Deutsche Telekom (https://open-telekom-cloud.com) is the biggest OpenStack platform in Europe. It facilitates its customers to run a workload in multiple cloud providers.

In this presentation, the speakers explain the reason why and how the standard specification TOSCA helps the users of Open Telekom Cloud to design their applications once and run anywhere by using the tool the Cloud Topology Designer (https://designer.otc-service.com).
