Hello Experts,
We are planning to role out our Dynamics 365 online instance hosted in Germany Data Center. We have a global user base. I came across some articles wherein it was mentioned that if the instance is hosted outside of China then there are performance issues faced by users in China due to country level firewall restrictions. On reading further we found that MS has tied up with a local China vendor to provide local hosting of D365 online instances. However there are lot of key features which don't work for the instanced hosted on the 21Vianet data centers like Flow, Discovery Service, Portal etc.
One suggestion came up was to host one instance close to China e.g. Japan but that adds a lot of overhead for us in terms of testing, deployment, maintenance etc.
I am looking for suggestions from the experts on how they have tackled this situations.
1. Have you come across similar situation and how has been performance of D365 in China if it was hosted in European data centers? If so, what are the best practices to avoid such issues?
2. If we need to have one instance in China to avoid issues then, are there any documented workarounds available to support the feature that are not support on the Chinese instances like Flow, Global Discovery Service, Portal etc.
3. If we host one instance in Japan instead of China, will it avoid the performance and connectivity issues for users in China?
4. If we host only one instance in Japan and none in Europe will it ensure optimal performance across the globe and will it have and GDPR related concerns?
If so, what are the best practices to avoid such issues?
