A cloud systems administrator needs to migrate several corporate applications to a public cloud provider and decommission the internal hosting environment.
This migration must be completed by the end of the month.
Because these applications are internally developed to meet specific business accounting needs, the administrator cannot use an alternative application.
Which of the following BEST describes the approach the administrator should use?

The BEST approach for the cloud systems administrator to use in this scenario is a Lift and shift migration strategy.
Lift and shift is a migration strategy that involves moving an entire application stack from one environment to another without making any significant changes to the application architecture. It's also known as "rehosting" because the goal is to move the application as-is to the new environment, without modifying it.
This approach is particularly suitable for internally developed applications that have been customized to meet specific business requirements, as in this scenario. The administrator cannot use an alternative application because these applications are specifically designed to meet the company's accounting needs.
Lift and shift also provides a quick and efficient way to migrate applications. Since there is no need to modify the application code, the migration can be completed relatively quickly. This is important because the administrator has a tight deadline of the end of the month.
The hybrid deployment approach, which involves using both public and private cloud environments, would not be appropriate in this scenario since the goal is to decommission the internal hosting environment.
Phased migration approach could be an option, but it involves breaking the migration into smaller chunks and migrating them over time. This approach would not be the best option as it would likely extend the migration timeline beyond the end of the month deadline.
The rip and replace approach involves replacing the existing application entirely with a new one. This approach is not suitable in this scenario because the administrator cannot use an alternative application due to the unique business accounting needs of the company. Additionally, this approach can be costly and time-consuming, which is not ideal given the tight deadline.
