For migrating a virtual machine using VMware vSphere vMotion from an on-premises data center to VMware Cloud on AWS SDDC, specific network requirements must be met. A Layer 2 connection (B) ensures that VMs can retain the same IP address and network settings post-migration, facilitating seamless migration without the need for reconfiguration. AWS Direct Connect (C) establishes a dedicated network connection between the on-premises data center and AWS, providing a more reliable and consistent network experience compared to internet-based connections. This setup is crucial for high-bandwidth, low-latency connections required by vMotion to efficiently transfer VM memory and state information during migration.
