Zorluk: ZorHybrid and VMware Cloud on AWS Migrations

An enterprise is migrating 25 critical business application virtual machines (VMs) from an on-premises VMware vSphere 7.0 cluster to a VMware Cloud on AWS (VMC on AWS) Software-Defined Data Center (SDDC). The database VMs are highly sensitive to latency and write transactions continuously, requiring zero downtime during migration (recovery time objective (RTO) of zero). The application components use hardcoded IP addresses that cannot be changed during the migration. The enterprise has a multi-account AWS structure and requires that the migrated VMs privately resolve DNS names in an Amazon Route 53 Private Hosted Zone (PHZ) hosted in a shared services AWS account. In addition, the VMs in the SDDC must communicate privately with resources in multiple spoke VPCs across different AWS accounts. The network between the on-premises datacenter and AWS is a 10 Gbps AWS Direct Connect connection. Which migration and networking strategy should the Solutions Architect implement to satisfy these requirements?

  1. A
    Extend the on-premises network using VMware HCX Network Extension to preserve VM IP addresses. Use HCX Bulk Migration to replicate and migrate the VMs in a single parallel batch. Connect the VMC on AWS SDDC to the spoke VPCs using VMware Transit Connect, and associate the Route 53 Private Hosted Zone in the shared services account with the Connected VPC in the customer AWS account.
  2. Extend the on-premises network using VMware HCX Network Extension to preserve VM IP addresses. Use HCX Replication-Assisted vMotion (RAV) to migrate the VMs with zero downtime. Connect the VMC on AWS SDDC to the spoke VPCs using VMware Transit Connect, and associate the Route 53 Private Hosted Zone in the shared services account with the Connected VPC in the customer AWS account.Cevap
  3. C
    Extend the on-premises network using VMware HCX Network Extension to preserve VM IP addresses. Use HCX Replication-Assisted vMotion (RAV) to migrate the VMs with zero downtime. Connect the VMC on AWS SDDC and the spoke VPCs directly to a shared AWS Direct Connect Gateway to enable inter-VPC and SDDC communication, and associate the Route 53 Private Hosted Zone in the shared services account with the Connected VPC in the customer AWS account.
  4. D
    Extend the on-premises network using VMware HCX Network Extension to preserve VM IP addresses. Use HCX Replication-Assisted vMotion (RAV) to migrate the VMs with zero downtime. Connect the VMC on AWS SDDC to the spoke VPCs using VMware Transit Connect, and deploy Route 53 Resolver endpoints in the shared services account without associating the Private Hosted Zone with the Connected VPC.

Cevap

The correct strategy is to extend the on-premises network using VMware HCX Network Extension, migrate the virtual machines using HCX Replication-Assisted vMotion (RAV) to avoid downtime, route multi-account traffic using VMware Transit Connect, and associate the Route 53 Private Hosted Zone with the Connected VPC in the customer account.
The correct answer correctly addresses the requirements for network extension, zero-downtime migration, and multi-account connectivity. VMware HCX Network Extension extends the L2 network to preserve VM IP addresses. HCX Replication-Assisted vMotion (RAV) allows parallel background replication of multiple VMs with a zero-downtime hot switchover. VMware Transit Connect provides high-bandwidth, low-latency connectivity between VMC SDDCs and multiple VPCs. Finally, associating the Private Hosted Zone with the Connected VPC in the customer AWS account ensures private DNS resolution works for the migrated VMs.

Adım Adım Çözüm

1
Extend the on-premises L2 network using VMware HCX Network Extension.
Ensures that VMs can retain their existing IP addresses after migrating to VMware Cloud on AWS, avoiding complex application reconfigurations.
The application components have hardcoded IP addresses that cannot be changed.
2
Migrate the virtual machines using VMware HCX Replication-Assisted vMotion (RAV).
Replicates VM data in the background and switches over to VMware Cloud on AWS with zero downtime.
The database VMs write transactions continuously and require an RTO of zero (no downtime).
3
Establish multi-account network connectivity using VMware Transit Connect.
Routes traffic between the VMC on AWS SDDC and multiple spoke VPCs across different AWS accounts.
Direct Connect Gateway does not support transitive routing between attached VPCs, making Transit Connect necessary.
4
Associate the Route 53 Private Hosted Zone (PHZ) in the shared services account with the Connected VPC of the VMC SDDC.
Allows VMs in the SDDC to resolve private DNS names defined in the PHZ.
Route 53 PHZs require explicit association with the VPC from which DNS queries originate; DNS resolution is not transitive over Transit Gateway connections.
