AWS Server Migration Service (SMS)

AWS Server Migration Service Cheat Sheet

  • An agentless service for migrating thousands of on-premises workloads to AWS. This is the enhanced replacement of Amazon EC2 VM Import service.
  • SMS orchestrates server migrations by:
    • automating incremental replication of live server volumes to the AWS cloud
    • allowing customers to schedule replications
    • track the replication progress of a group of servers via Management Console
  • Each server volume replicated is saved as a new Amazon Machine Image (AMI), which can be launched as an EC2 instance in the AWS cloud. If you are using application groupings, Server Migration Service will launch the servers in a CloudFormation stack using an auto-generated CloudFormation template.
  • AWS SMS creates a new EBS snapshot with every replication.  It replicates server volumes from your on-premises environment to S3 temporarily and purges them from S3 right after creating EBS snapshots.
  • You can migrate virtual machines from VMware vSphere and Windows Hyper-V to AWS.
  • You can replicate your on-premises servers to AWS for up to 90 days (per server). After that, your replication job will be automatically terminated. This duration can be increased by submitting a request to AWS.
  • Customers are able to migrate large volumes up to 16 TB.

AWS Server Migration Service Connector

    • A pre-configured FreeBSD virtual machine (in OVA format). You need to first deploy the SMS Connector virtual appliance on each of your on-premises VMware vCenter environment to use AWS SMS.
    • The AWS Server Migration Service Connector supports password-based proxy, but not NTLM-based proxy.
    • The SMS Connector can be configured to use SCVMM or standalone Hyper-V VMs.
    • You need two separate SMS Connectors to simultaneously migrate VMs from both VMware and Hyper-V environments.
  • AWS Server Migration Service offers multi-server migration support as well. You can migrate entire application stacks rather than migrating each server individually. This is done through an auto-generated CloudFormation template (non-modifiable).
  • AWS Server Migration Service has the ability to resume failed replication jobs, allowing you to take remedial action and resume the replication from the point it failed, as opposed to restarting the job. This adds resiliency to the migration process and allows you to complete large-scale server migrations in an efficient and timely manner.

AWS SMS Security

    • Replicated server volumes are encrypted in transit by TLS.
    • AWS SMS Connector only captures basic VM inventory information and snapshots of server volumes from VMware vCenter and does not gather any sensitive information.

AWS SMS Pricing

    • You incur charges with every S3 usage and EBS snapshot created by AWS SMS.
