The European Weather Cloud (EWC) is connecting connects the cloud environments of ECMWF and EUMETSAT into a larger entity, providing unified access to online data, functions, and services from both organisations. The key feature of the EWC is the provisioning of data proximate computing facilities to the meteorological community to boost their developments, ease access to large datasets and potentially support their operational services
...
The service consists of cloud resources provided by EUMETSAT and ECMWF and controlled by a cloud management software. Users portal hosted at both ECMWF and EUMETSAT. Users are given an account (tenancy) on one of these portals, and can deploy and manage their virtual resources and application environments to both cloud infrastructures infrastructures (EUMETSAT and ECMWF) regardless of the home location of their cloud tenancy (any of the cloud infrastructures) tenancy.
Users deploy their own applications and are responsible of for the maintenance and the application environment operated they operate in the EWC. Terms and Conditions including eligibility to use the service, roles, and responsibilities are available at: Terms and Conditions for the Use of European Weather Cloud Operational Service
Cloud Management Services
EWC also offers services for cloud management. These are provided via the Morpheus API/GUI (see https://morpheusdata.com/ for general information).
Virtual environment provisioning
...
Users can define tasks containing shell scripts and Ansible playbooks. This functionality enables users to deploy their infrastructure as code(IaC), including software provisioning, configuration management, and application deployment functionalities. The tasks can include runtime and provisional workflows. Tasks and workflows can be executed in the running VMs or during deployment respectively. The workflow execution can be triggered from the UI and from the CLI / Rest API. The tasks and workflows can be fetched from user-defined GIT repository via integrations.
