The European Weather Cloud (EWC) teams at ECMWF and EUMETSAT are pleased to invite you to the first thematic EWC webinar of 2026.
These recurring thematic webinars are aimed at all users of the EWC service, provided by EUMETSAT and ECMWF, which is available to all ECMWF and EUMETSAT Member and Co-operating States. Our primary objective is to provide guidance to users on how to effectively use the different capabilities of the EWC.
Information on the previous webinars, including their recordings, can be found here.
In this webinar, we will introduce the EWC Identity and Access Management (IAM), the service that will be used the service that will be used for authentication and access to the available EWC services. We will also provide a first look at OpenStack Horizon, the web interface for managing cloud resources (replacing Morpheus).
Participants will learn how to:
- Use the EWC Identity and Access Management (IAM) system, common administrative tasks, user roles and access to EWC services. Moreover how you can create clients that can you use for your workloads.
Access the OpenStack Horizon dashboard and perform similar actions that user you could do on Morpheus.
By the end of this session, participants will have gained an understanding of EWC IAM and initial understanding of OpenStack Horizon.
Attendance
This webinar is open to anyone from an ECMWF or EUMETSAT Member and Co-operating State.

Dear EWC users,
Following a detailed analysis of user feedback, Morpheus features usage, and an evaluation of open-source alternatives, we have decided to decommission Morpheus in favour of alternative solutions providing better integration with standard tools and alignment with the long-term goals of the EWC.
In particular:
As a replacement of Morpheus web interface to manage cloud resources, we have selected Horizon, the OpenStack Dashboard.
- The EWC Community Hub provides a more open approach for application blueprints because items rely on open source solution and can be easily customised and adapted for the different needs and environments
- Access to EWC services (including Horizon) will be accomplished through the EWC Identity and Access Management (IAM). Existing users will be onboarded and migrated into EWC IAM. Over the coming weeks, you may receive emails from the EWC team related to IAM onboarding.
🗓️ Indicative Timeline (Subject to Updates)
The following timeline is indicative and will be refined and updated regularly as the transition progresses:
Availability of the new solution – End of Q1
User webinars – Dates to be announced closer to each event
Progressive transition of users and workloads – Q2–Q4
End-of-year completion of the transition and Morpheus decommissioning – End of year
Further communications will be sent at each major milestone.
📣 User Support and Ongoing Communication
Please be assured that you will be supported throughout the entire transition. We will provide clear documentation, guidance, and direct communication to help you at every stage. No immediate action is required at this point.
To keep you fully informed, we will:
Share regular updates via official EWC communication channels, including monthly updates and any changes to the timeline
Announce webinars to present the new solutions, explain the changes, and answer your questions
Publish updated documentation, how-to pages on how to perform similar actions in the new system and FAQs to support your preparation for the transition
We appreciate your patience and please contact us via Support Ticket or via Rocketchat if you have any questions or concern.
EWC Team
The EWC Team on EUMETSAT side is pleased to announce an upcoming webinar on 18 March 2026, from 08:00 to 11:00 UTC, dedicated to the EWC cloud migration of the EUMETSAT side of the EWC.
Based on the current timeline, the new cloud infrastructure is planned to be in place by the end of Q1 2026, after which tenancy migration will begin.
This online webinar will present the new infrastructure, outline the planned migration approach and timeline, explain the available migration options, and provide guidance on next steps. There will also be dedicated time for questions and answers, allowing participants to raise specific topics and clarify any concerns.

Dear EWC users,
Happy Ney Year from the EWC Team!
On Tuesday, 27 January 2026, starting at 7:00 UTC, a maintenance window for EWC IAM is scheduled with an expected duration of approximately 2 hours. During this period, short interruptions to the availability of the EWC IAM system will occur.
The EWC IAM system will be migrated from https://iam.eumetsat.europeanweather.cloud to https://iam.europeanweather.cloud
This change is required for the transition of the EWC Identity and Access Management (IAM) system from the pilot phase to operational service and preparation for general availability to all EWC users.
All currently managed systems through EWC IAM will be automatically reconfigured as part of this change. However, users with accounts will need to use the new address to access the IAM administration console.
The user documentation, available at https://confluence.ecmwf.int/display/EWCLOUDKB/EWC+Identity+and+Access+Management+%28IAM%29+Service will be updated accordingly to reflect the new addresses.
We apologise for any inconvenience this may cause and thank you for your understanding.
For any questions or comments or issues, please contact us via Support Ticket or via Rocketchat
Kind regards,
EWC Support Team

Dear all ,
We are planning an upgrade of Morpheus at EUMETSAT side of EWC on Thursday 4 December2025 between 8:30 UTC and 10:30 UTC.
During the upgrade window, the Morpheus user interface and APIs will not be available. However, the update does not impact existing workloads, so your VMs will be unaffected, and the Openstack API will still be available.
We apologise for the inconvenience and thank you for your understanding.
For updates during the maintenance, please refer to the EWC service status page
For any questions or comments or issues, please contact us via support ticket or via Rocketchat
Thank you,
The EWC Team
Dear @all ,
We would like to inform you about an upcoming maintenance window on EUMETSAT side of the EWC that will take place on Tuesday, 18 November 2025, between 10:00 UTCand 11:00 UTC.
This maintenance will affect interaction with OpenStack resources and EWC services on EUMETSAT side of the EWC.
This intervention is a necessary step to ensure the continued security and reliability of all workloads hosted on the EWC on EUMETSAT side.
What to expect:
• Temporary unavailability of VM lifecycle operations (create/modify/delete) from Morpheus and from Openstack directly.
• Short interruptions in storage and network access.
• Existing VMs are expected to remain running, although workloads that cannot tolerate brief disruptions may experience impact.
Recommendations for users:
If your workload is not resilient to temporary disruptions, we advise you to stop it before the maintenance begins and restart it once the maintenance is complete.
Our team and the cloud provider will be closely monitoring the process to minimise service impact.
We apologise for any inconvenience this may cause and thank you for your understanding and cooperation.
For updates during the maintenance, please refer to the EWC service status page
Best regards,
EWC Team on the EUMETSAT side
