MSTC is hosted in Microsoft Azure (Azure) and Amazon Web Services (AWS).
We use Azure datacenters located in Amsterdam, The Netherlands.
For AWS we use datacenters located in Frankfurt, Germany.
It depends on which modules are in scope of the usage by a client or prospect whether both Azure and AWS are relevant to a client/prospect.
In case only MSTC Tender management is in scope it is just the Azure datacenters that are relevant. When also one of the other MSTC modules (e.g. Contract management) is in scope the AWS datacenters are relevant as well.
