Zorluk: OrtaHybrid and VMware Cloud on AWS Migrations

A financial services firm is preparing to migrate its core transactional and analytical platforms from an on-premises VMware vSphere environment to a VMware Cloud on AWS SDDC. The transactional databases require live, zero-downtime replication and migration (hot migration) to prevent business disruption, while the batch processing engines can be cut over with minimal downtime during a scheduled window. All migrated virtual machines must preserve their original IP addresses to prevent breaking hardcoded database connection strings. A 2 Gbps AWS Direct Connect connection is available for the migration.

Which of the following components or migration methods should the solutions architect configure to satisfy these requirements? (Select TWO.)

  1. VMware HCX Replication-Assisted vMotion (RAV) to migrate the transactional database virtual machines without downtime.Cevap
  2. VMware HCX Network Extension to stretch the on-premises Layer 2 networks to the VMware Cloud on AWS SDDC.Cevap
  3. C
    AWS Application Migration Service (MGN) using a pilot light replication pattern to migrate the transactional databases.
  4. D
    A Direct Connect Gateway connected directly to a Transit VIF to establish transitive VPC-to-VPC routing between the SDDC and other AWS accounts without an intermediate Transit Gateway.
  5. E
    A Route 53 Private Hosted Zone (PHZ) containing the VMC management DNS records configured without association to the SDDC VPC or a shared services VPC.

Cevap

Configure VMware HCX Replication-Assisted vMotion (RAV) to migrate database virtual machines without downtime and VMware HCX Network Extension to stretch the on-premises Layer 2 networks to the VMware Cloud on AWS SDDC.
The correct options are VMware HCX Replication-Assisted vMotion (RAV) and VMware HCX Network Extension. VMware HCX Network Extension allows extending Layer 2 networks so that virtual machines retain their IP addresses upon migration. VMware HCX Replication-Assisted vMotion (RAV) combines parallel replication with live vMotion switchover, meeting the zero-downtime migration requirement for the transactional databases.

Adım Adım Çözüm

1
Analyze the business requirements for IP retention and zero-downtime migration.
Identify that the virtual machines must retain their IP addresses, and transactional database virtual machines require hot migrations (zero downtime).
This establishes that a Layer 2 network extension is needed and a live migration mechanism must be used.
2
Select the correct VMware HCX migration method for zero-downtime databases.
Choose VMware HCX Replication-Assisted vMotion (RAV) or HCX vMotion.
HCX RAV allows scheduling bulk migrations with zero-downtime switchovers, satisfying the live migration requirement for transactional databases.
3
Select the correct network configuration for IP retention.
Configure VMware HCX Network Extension (L2C) to stretch the on-premises network.
L2 extension allows virtual machines to move to the cloud without needing to change their IP addresses, preventing broken database connections.

Anahtar Kavram

Selecting proper VMware HCX migration profiles (Replication-Assisted vMotion vs Bulk Migration) and Layer 2 Network Extensions to meet RTO/RPO and IP retention requirements.
