- https://docs.aws.amazon.com/server-migration-service/latest/userguide/server-migration.html
- automates the migration of your on-premises VMware vSphere, Microsoft Hyper-V/SCVMM, and Azure virtual machines to the AWS Cloud. AWS SMS incrementally replicates your server VMs as cloud-hosted Amazon Machine Images (AMIs) ready for deployment on Amazon EC2
- There is no additional fee to use Server Migration Service. You pay the standard fees for the S3 buckets, EBS volumes, and data transfer used during the migration process, and for the EC2 instances that you run.
- Server Migration Connector –
§ FreeBSD VM , gets installed on-premises
§ features connectors for VMWare, MS HyperV, Azure
§ uses port443 to secure transfer data int AWS
- Benefits:
§ Simplify the cloud migration process. Can have a one-of migration push OR a continuous automatic replication of volumes of live servers to AWS
§ Orchestrate multi-server migrations - schedule replications and track progress of a group of servers that constitutes an application.
§ Incremental migration - can test small changes iteratively and save on network bandwidth
§ Minimize downtime - incremental replication minimizes downtime during the final cutover.
- Resulting AMIs can be encrypted, SNS can be used for status updates
- 50 concurrent migrations max
- 90-day default service usage per migrated VM – starting from the initial replication
- 50 concurrent application migrations with 10 groups max with 50 servers in each application
- Limitations:
§ Each VM will have only one ENI after migration; multiple ENIs are not supported
§ Each VM will get a single internal IP assigned
§ IPv6 is not supported
§ Replication fails for VMs with more than 22 volumes attached
§ AMIs with volumes using EBS
encryption is not supported – AMI can be encrypted by not EBS
