2) The platform
User Frontend Web Server CAE Backend
The infrastructure: A distributed hardware and software system.
● No special HW / SW requirements
● Reliable internetaccess
● Browser-based● General data
management, storage & backup
● On-demand compu-ting power
● Different IaaS prov-iders available

4) CAE and „the Cloud“The status of cloud-based CAE today
Technical implementations:
● Local desktop client, remote computation● Remote-desktop interaction● Browser-based interaction
Pricing models:
● „Bring your own license“ (BYOL)● Pre-paid simulation contingent● On-demand usage („pay-as-you-go“)
Cloud-based CAE today
Basic Advantages:
● Scalability● Flexibility
Challenges:
● Data traffic● Internet dependency● Performance reduction through virtualization● „Cloud-Image“ problem
The Cloud discussion in a nutshell
