Agentless snapshot-based replication allows you to replicate source servers on your vCenter environment into AWS without installing the AWS Replication Agent.

In order to use agentless replication, you must dedicate at least one VM in your vCenter environment to host the Application Migration Service vCenter Client. The Application Migration Service vCenter Client is a software bundle distributed by Application Migration Service and is available for installation as a binary installer. The installation process will install services on the client VM which will allow Application Migration Service to remotely discover your VMs that are suitable for agentless replication, and to perform data replication between your vCenter environment and AWS though the use of periodic snapshot shipping.

Agentless snapshot based replication is divided into two main operations: discovery and replication:

The discovery process involves periodically scanning your vCenter environment to detect source server VMs that are suitable for agentless replication, and adding these VMs to the Application Migration Service Console. Once a source server has been added, you may choose to initiate agentless replication on the source VM using the Application Migration Service API or Console. The discovery process also collects all of the necessary information from vCenter in order to perform an agentless conversion process once a migration job is launched.

The replication process involves continuously starting and monitoring the “snapshot shipping processes” on the source server VM being replicated. A “snapshot shipping process” is a long running logical operation which consists of taking a VMware snapshot on the replicated VM, and launching an ephemeral replication agent process which uses VMware’s Changed Block Tracking (CBT) feature to identify changed volume data location, using Virtual Disk Development Kit (VDDK) to read the modified data, and sending the data from the source environment to the customer’s target AWS account. The first snapshot shipping process performs an “initial sync” which sends the entire disk contents of the replicating VM into AWS. Following snapshot shipping processes will leverage CBT in order to only sync disk changes to the customer’s target AWS account. Each successful snapshot shipping process completes the replication operation by creating a group of consistent Amazon EBS snapshots in the customer’s AWS account, which can then be used by the customer to launch test and cutover instances through the regular Application Migration Service mechanisms.

The following are the main system components of agentless replication:

  • Application Migration Service vCenter Client – A software bundle that is installed on a dedicated VM in your vCenter environment in order to facilitate agentless replication.

  • vCenter Replication Agent – A java agent that is based on the AWS Replication Agent, which replicates a single VM using VDDK and CBT as the data source instead of the Application Migration Service driver (that is used by the AWS Replication Agent)

  • Application Migration Service Service

  • Application Migration Service Console
