Hi @nareshsharma.
Nice to meet you, i am VMware Staff Customer Success Architect for Muti-Cloud solutions and i will help you with the WSFC topic.
The answer is yes, it is supported.
There is a nice blog post with the title "Deploying a Windows Server Failover Cluster (WSFC) in the Supported Configuration on VMware Cloud on AWS and vSAN" and will help you to achieve the right configuration. A stretched cluster SDDC uses vSAN synchronous replication for VMDKs, including shared VMDKs using cross-AZ network connection, so you need to evaluate a possible performance impact on applications deployed o top of a WSFC.
This post will be very soon updated (this week, hopefully today/tomorrow) to reflect this configuration is also supported on VMware Cloud on AWS, link: https://blogs.vmware.com/apps/2021/01/wsfc-validation-vmware-vmc.html
Also. we generally refer to the on-premises documentation that you can find in this post "WSFC with Native Shared Disks on vSAN 6.7U3 Stretched Clusters", link:https://blogs.vmware.com/virtualblocks/2019/10/09/wsfc-stretched-clusters/
Last but not least, are you planing to migrate WSFC workloads to the cloud or deploy them from the scratch?
Hope this help!
Regards,
