A lift and shift migration approach, also known as rehosting, is a cloud migration strategy where applications and infrastructure are moved from one environment to another without making substantial changes to the underlying architecture123. This approach can be faster, cheaper, and less risky than other migration strategies, as it does not require extensive redesign or reconfiguration of the applications. However, it may also limit the ability to leverage the native features and benefits of the cloud platform, such as scalability, elasticity, and performance1245.
One of the challenges of a lift and shift migration is transferring large amounts of data and virtual machines over the network, which can be time-consuming, costly, and prone to errors. To overcome this challenge, some cloud providers offer a technique where the customer can transfer all of their on-premises data and virtual machines to an appliance, such as a physical storage device or a server, and then ship it to the cloud provider. The cloud provider then uploads the data and virtual machines to the cloud platform, where they can be accessed by the customer12. This technique can reduce the network bandwidth and latency issues, as well as the security risks, associated with transferring data over the internet. However, it may also introduce additional costs and delays for shipping and handling the appliance, as well as the risk of damage or loss during transit2.
Therefore, transferring all of a customer’s on-premises data and virtual machines to an appliance, and then shipping it to a cloud provider is a technique used in a lift and shift migration approach. References:
