VM Migrations AWS <=> On-Premises

Application Discovery Service (AMS)

• Allows us to discover on-premises infrastructure:
  • What VM we have
  • What CPU and memory they are allocated
  • MAC addresses
  • Resource utilization
  • etc.
• It also tracks these properties over time for more effective migration
• AMS runs in 2 modes:
  • Agentless (Application Discovery Agentless Connector):
    • OVA appliance integrating with VMWare
    • Measures performance and resource usage, information which can be obtained from the outside of a VM
  • Agent Based mode: offers additional information from inside of a VM
    • Offers data gathering for network, processes, performance
    • We can see applications running on a VM
    • We can even see dependencies between VM based on network activity
• AMS integrates with AWS Migration Hub and Athena
• AWS Migration Hub: tracks migrations of different types in AWS

Server Migration Service (SMS)

• Used to migrate whole VMs into AWS (including OS, Data, Apps, etc.)
• This is the tool which actually performs the migration
• It runs on agentless mode using a connector which runs on-premises
• Integrates with VMware, Hyper-V and AzureVM
• SMS does incremental replication of live volumes
• Offers orchestration of multi-servers migrations
• Creates AMIs which can be used to create EC2 instances
• Integrates with AWS Migration Hub
