We’re excited to announce that HTC Batch Processing on EUMETSAT side of the EWC now supports Singularity containers!
What is Singularity?
Singularity is a widely-used container technology designed specifically for high-performance computing (HPC) and scientific workloads. Unlike traditional container platforms, Singularity focuses on portability, security, and seamless integration with existing HPC infrastructure — allowing users to package entire applications and environments into a single, portable image.
What does this mean for you?
You can now submit and run batch processing jobs to the batch processing system using your Singularity container images, alongside existing container options.
You can find more information and an example job for singularity here: EUMETSAT - HTC batch processing#SingularityjobinHTCondor
You can join the common pool of nodes deploying execute nodes that have docker and singularity available!
Dear all,
We notify you about an upcoming maintenance on the ECMWF cloud infrastructure scheduled on the following days 6, 7 and 8 May 2025 from 08:00 to 14:00 UTC each day.
The maintenance window, which is applicable to the cloud cluster in CCI1, is done in order to upgrade the version of Openstack running on the system.
During that maintenance window, there will be possible disruptions on the service APIs for up to 30 minutes.
For further updates during the sessions, you can monitor the ECMWF Service Status page.
We apologise in advance for any inconvenience this may cause you.
Kind regards,
EWC Team at ECMWF
Dear all,
we are pleased to share that a new use case has been published on the EWC website.
- Processing Climate Data Records (CDRs) at EWC

If you happen to be in Bologna that week, why not join us for the EWC workshop as well? Don't forget to register if you do!
Please feel free to share this invitation with your colleagues who may be interested in attending.
We look forward to welcoming you to Bologna for this exciting event!
We are currently experiencing performance issues with object storage (S3) on the EUMETSAT side of the EWC. You may notice occasional timeouts and slow performance. Our infrastructure provider is aware of the issue and is actively working to resolve it.
We apologize for the inconvenience!
Dear all,
We are currently experiencing a network issue at EUMETSAT, which is affecting access to Morpheus. As a result, Morpheus is temporarily unavailable.
However, please note that your workloads are continuing to run without any issues.
If you have any other problem please contact us in rocketchat or through support ticket.
We apologize for the inconvenience.
Thank you for your understanding,
EWC Team on EUM side
Dear ,
On Monday, April 28, between 10:00 and 11:00 CEST, there will be a maintenance window for Keystone, Keycloak, and Horizon, where associated IPs will be upgraded in order to deploy a new High Availability configuration for internet facing systems.
In case you need to enable any firewall, the new IPs will be:
Name: keystone.cloudferro.com
Address: 194.146.60.11
Name: horizon.cloudferro.com
Address: 194.146.60.12
Name: identity.cloudferro.com
Address: 194.146.60.13
Impact: No disruption to running workloads. Users may see intermittent issues in Morpheus when deploying, modifying, or deleting resources, and the clouds may appear “unavailable.” Users with OpenStack application credentials might also face brief connectivity issues.
No action required before or after the window. You can continue working on your VMs as usual.
Thank you for your understanding,
EWCTeam on EUM side
The European Weather Cloud (EWC) teams at ECMWF and EUMETSAT are pleased to invite you to the second thematic EWC webinar of 2025.
It will happen on Wednesday 14 May 2025 from 08:00 to 09:00 UTC (09:00 - 10:00 BST, 10:00 - 11:00 CEST, 12:00-13:00 EEST).
These recurring thematic webinars are aimed at new or prospective 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 focus on automating common tasks using Infrastructure as Code in the European Weather Cloud, through the recently announced Openstack API using Openstack Application Credentials in EWC.
By the end of this 1-hour session, participants will have gained a better understanding of how to use standard DevOps tools (OpenTofu, Ansible) to automate the creation of computer resources on the EWC, to query data on ECMWF (MARS) or EUMETSAT (EUMDAC).
Attendance
Please note that the webinar is open to anyone interested from an ECMWF or EUMETSAT Member and Co-operating State.
If you would like to attend the webinar, please complete the registration: https://events.ecmwf.int/event/477/registrations/344/
We will alert you of your acceptance to the webinar and send you all the joining information and Microsoft Teams meeting details in due course.
The webinar will be conducted in English.
Dear all,
we are pleased to share a new use case has been published on the EWC website.
We will share more in the future and we would like also to remind that the opportunity to contribute to the EWC website with your use cases running on the EWC is always valid! If you would like your use case featured there, please contact us via our Support Portal or discussion platform.
We are pleased to announce the availability of new updated images at both ECMWF and EUMETSAT for:
- Rocky Linux 8.10
- Rocky Linux 9.5
- Ubuntu 22.04
You can already deploy the new images from Morpheus using the usual instance types. You will find more details on these images on this page: EWC Virtual Images Available
We also took advantage of this update to harmonise the instance types (and their logos!) and the layouts between ECMWF and EUMETSAT.
As always, if you need any support, please do get in touch with us on the European Weather Cloud Discussion Platform or through the Support Portal.
Kind regards,
EWC Team
Dear all,
we are pleased to share a new use case has been published on the EWC website:
We will share more in the future and we would like also to remind the opportunity to contribute to the EWC website with your use cases running on the EWC is always valid!
If you would like your use case featured there, please contact us via our Support Portal or discussion platform.
We are exploring how users of the European Weather Cloud (EWC) may interact with current services such as Morpheus cloud orchestrator, as well as with additional services such as Git code repositories and container registries. If you are a current or a potential user of the EWC, we would kindly ask you for a few minutes of your time to complete the following survey:
https://ec.europa.eu/eusurvey/runner/EWC-additional-services-needs
Your feedback is essential in helping us improve the EWC and better support your needs. If you have any further questions or would like to stay engaged with the community, don’t forget to visit our Support Portal for assistance or join the discussion on our Discussion Platform to connect with other users and share your experiences.
Thank you again for your valuable input!
After the maintenance on EUMETSAT side of the EWC, a last intervention is still necessary for Morpheus to correctly receiving metrics and logs. You might notice that some of the health checks reports from your VMs are not in a healthy state. However, this issue is only related to the way in which Morpheus shows this information, and your workloads are actually fine. We are working on a solution and will provide more information as soon as possible.
We would like to also highlight that if you notice issues with running workflows or deploying instances in your tenancy, the LDAP VM might need to be restarted. If this doesn't resolve the problem please contact us in rocketchat or through support ticket.
Since we started this journey, and as we have evolved our EWC offering, certain aspects of the overall experience had started to slowly diverge on both sides of the EWC. Based on feedback received by our users, ECMWF and EUMETSAT EWC Teams have embarked in a process to harmonise the user experience from users, regardless of what side of the EWC they work on.
We focused on identifying and analysing any differences in terms of infrastructure, setup, support and use cases and started to consolidate the approaches and offering wherever possible. As a result, you may have already noticed some work being done in several key areas:
Documentation
We have reviewed all our articles in our Knowledge base and made sure all the instructions applied to both cloud backends, wherever possible. Certain pages with similar instructions for both backends have been generalised, simplified or merged.
Outreach & Training
It is not something new, but we plan to continue to offer joint EWC Training and Tutorials, including webinars and events like the User Workshop.
Morpheus experience
While we keep both ECMWF and EUMETSAT Morpheus portals to access and manage your virtual infrastructure at EWC, some work is ongoing to bring the interaction with them as close as possible, converging in similar default setup and naming conventions for the same elements.
VM images
We now share a common set of base Virtual Machine images featuring Rocky Linux and Ubuntu across the EWC, and aim to jointly release any updates to them when needed.
EWC common community templates
A great deal of effort has been invested to ensure that common templates, instance types and workflows are consistent and can work on both sides.
Openstack API access
For those users wanting to automate their deployments and have finer control over their infrastructure, we have recently jointly announced the access to the cloud backends directly. Beyond the unavoidable minor differences from the different cloud providers, the process and experience when using this approach should be symmetric from the user point of view.
Looking ahead, the evolution of EWC underlying cloud infrastructure in the next years will continue to take into account all these harmonisation aspects in order to continue to offer users a consistent view and experience across the EWC. Behind the scenes, a major effort is underway towards the development of the new services coming up from the features roadmap, where we hope we can continue to deliver value for this community.
Dear ,
this is just a reminder for the maintenance starting today on EUMETSAT side of the EWC. In case of any questions, comments, or concerns, please contact us via our Support Portal or Discussion Platform.
Kind regards,
EWC Team at EUMETSAT side
