Zorluk: OrtaHybrid and VMware Cloud on AWS Migrations

An enterprise is planning to migrate its on-premises VMware vSphere 6.7 environment to VMware Cloud on AWS. The migration includes a set of active database virtual machines (VMs) that require zero-downtime live migration, and a group of non-critical web servers that should be migrated in bulk and cut over during a scheduled weekend maintenance window. Hybrid connectivity is established via a 1 Gbps AWS Direct Connect connection. Which two VMware HCX migration methods should the solutions architect select to meet these requirements?

  1. Use VMware HCX Replication Assisted vMotion (RAV) to migrate the database virtual machines.Cevap
  2. Use VMware HCX Bulk Migration to migrate the web server virtual machines.Cevap
  3. C
    Use VMware HCX Cold Migration to migrate the database virtual machines.
  4. D
    Establish transitive routing by connecting the on-premises VMware environment directly to a Direct Connect Gateway without using AWS Transit Gateway.
  5. E
    Create a Route 53 Private Hosted Zone (PHZ) in the VMware Cloud management account and assume it will automatically resolve across all spoke VPCs.

Cevap

Use VMware HCX Replication Assisted vMotion (RAV) for the critical database virtual machines to achieve zero downtime, and use VMware HCX Bulk Migration for the web server virtual machines to enable parallel replication with a scheduled weekend switchover.
VMware HCX Replication Assisted vMotion (RAV) combines the bulk replication capability of Bulk Migration with the zero-downtime switchover of vMotion, which satisfies the zero-downtime requirement for active databases. VMware HCX Bulk Migration uses host-based replication to move multiple virtual machines in parallel and allows the solutions architect to schedule the cutover window for the weekend, matching the web server requirement.

Adım Adım Çözüm

1
Evaluate the downtime tolerance for each workload class.
Database virtual machines require zero-downtime migration, while web servers can tolerate a scheduled weekend cutover.
This establishes the constraints for choosing the migration mechanism.
2
Match the database requirement to the appropriate HCX migration type.
Select Replication Assisted vMotion (RAV) which combines bulk data replication with zero-downtime vMotion switchover.
Pure vMotion is limited in throughput and parallel execution, whereas RAV replicates in bulk and performs hot migration switchovers.
3
Match the web server requirement to the appropriate HCX migration type.
Select Bulk Migration to perform parallel replications and schedule the final cutover to occur during the weekend.
Bulk Migration supports staging the virtual machines in parallel and executing the switchover at a pre-planned maintenance window.

Anahtar Kavram
