Questions about IEM Cloud

0
Hello,One of our customers is planning to use IEM Cloud and has a few questions:If they migrate from IEM Cloud to an IEM Virtual instance in the future, can they activate their existing Edge Devices without any data loss (i.e., without requiring a soft or hard reset)?Is there a maximum device limit per IEM Cloud instance?Can the current data storage (200 GB) and data traffic (1 TB inbound / 1 TB outbound) be scaled up if needed?Do we also need 'Industrial Edge Device Management Licenses' for the IEM Cloud Plan?Thanks

Hi Fatih,


1 -> Currently it is not possible to migrate/relocate Industrial Edge Device between IEMs. It is functionality we are currently considering but it is not possible at the moment. Stay tuned for future releases.



2 -> There is no limit in terms of licensing how many devices you can have on single IEM Cloud. You can find the details here https://www.dex.siemens.com/edge/get-started/industrial-edge-management-cloud


As a safe starting point you can have 1000 Industrial Edge Devices on single IEM Cloud. If you need more, I recomend to reach out to your local Siemens representative and we can find right configuration for you. As IEM is hosted in the cloud, we can easily add more resources so it is not the bottleneck from technical point of view.


3 -> if you need to extend the storage and bandwidth then please reach out to your local Siemens representative and we will find a solution. Currently we do not offer an extension via Marketplace that you could easily extend these parameters.


4 -> Yes, you need to purchase IED Management license for every device that is onboarded on IEM Cloud. https://www.dex.siemens.com/dex/edge/industrial-edge-marketplace/industrial-edge-device-license



Hope this helps,

Ondrej

For the IEM Cloud migration and scaling questions, I would suggest checking with Siemens/Mendix support for the exact licensing and infrastructure limits, but from an architecture perspective:


1. Migration from IEM Cloud to IEM Virtual

The Edge Device activation is usually tied to the IEM instance and its device registration. Before planning a migration, verify the supported migration path because moving between Cloud and Virtual instances may require re-registration depending on the setup.

I would not assume that devices can be moved without any changes. Confirm the migration procedure with Siemens to avoid any device reset/re-onboarding requirement.


2. Maximum number of Edge Devices

This depends on the IEM Cloud subscription plan and resource allocation. The limit is generally not only based on device count but also on:

  • number of applications deployed
  • telemetry frequency
  • storage usage
  • network traffic


3. Storage and traffic scaling

The included storage and bandwidth limits are usually based on the selected IEM Cloud plan. If the customer requires more than:

  • 200 GB storage
  • 1 TB inbound/outbound traffic

they should check available upgrade options with Siemens.


4. Industrial Edge Device Management Licenses

This depends on the Edge Device and licensing model. The IEM Cloud plan may cover the management platform, but individual device/app licenses can still apply depending on what is deployed.

For production planning, I would recommend contacting Siemens support/sales with:

  • expected number of Edge Devices
  • data ingestion rate
  • retention period
  • deployed Edge apps


so they can confirm the correct IEM Cloud sizing and licensing.


Kindly mark this as the accepted answer if it helps.
