Hosting and data location
The Eveos platform relies on several specialized cloud services for application hosting, data storage, authentication and sending communications.
The main application processing as well as data and file storage are located in France.
This page describes the components of the Eveos infrastructure, their role and their location. It can be shared with your organization’s IT, security, procurement or compliance teams.

Emails sent from the platform |
Backend and application processing
Section titled “Backend and application processing”The Eveos APIs and main application processing run on Microsoft Azure in the France Central region, on an Azure App Service (Linux) resource dedicated to the platform.
The backend receives requests from the application and handles business processing as well as exchanges with the various storage services.
Web application and server functions
Section titled “Web application and server functions”The Eveos web application uses Next.js and Vercel. The server
functions used for the dynamic processing of the interface are configured to
run in the Paris (cdg1) region.
Vercel is the application layer of the architecture: it does not store the platform’s business data, which resides in the database and file storage described below.
Application database
Section titled “Application database”The platform’s application data is stored in MongoDB Atlas, on Amazon
Web Services infrastructure located in Paris (eu-west-3).
The cluster used by Eveos is a dedicated cluster based on a replicated set of several nodes (replica set) to ensure service availability.
Data backups
Section titled “Data backups”Database backups are also stored in the AWS Paris (eu-west-3) region.
The platform benefits from automatic backups as well as a point-in-time recovery mechanism, allowing data to be restored to a specific moment if needed.
File storage
Section titled “File storage”Application files and documents are stored in Microsoft Azure Storage in the France Central region.
The storage uses local replication (Locally Redundant Storage) within the configured Azure region: redundancy copies remain in the same geographic region.
Depending on the features used, this storage may include:
- files imported into the platform;
- documents and images;
- graphic assets and media related to events;
- files generated by the platform.
Authentication
Section titled “Authentication”Eveos user authentication is handled by Amazon Cognito, configured in
the AWS Paris (eu-west-3) region.
This service manages the elements required to identify and authenticate users. The platform’s business data remains stored in the database described above.
Email sending
Section titled “Email sending”Transactional emails sent by the Eveos platform use Amazon Simple Email
Service (SES), configured in the AWS Paris (eu-west-3) region.
The data required to generate and deliver an email is transmitted to this service at sending time, for example:
- the recipient’s email address;
- the subject and content of the message;
- the information required to personalize the email.
SES is a delivery service: it does not constitute permanent storage of application data.
Data transit
Section titled “Data transit”When using the platform, dynamic requests are processed by the Eveos application and then forwarded to the backend hosted on Microsoft Azure in France.
Depending on the action performed, the backend may then access the database, the file storage, or the specialized services required for authentication or email sending.
