1. What is an example of rehosting an application?
- Before moving an application to the cloud, the
application is rewritten in a new programing language.
- During a migration, older applications are
discovered. They are no longer needed and can be turned off.
- A containerized application can be moved from on
premises to the cloud without making any changes.
- All on-premises applications and
resources can be easily moved to the cloud except for the load balancers.
The existing load balancers are replaced by Elastic Load Balancing (ELB)
load balancers.
Explanation: In the
process of rehosting an application, the program is moved from one environment
to another without any substantial modifications being made to its actual
design. To put it another way, it is the same as taking the application and
transferring it to a different hosting environment. An example of this would be
moving a conventional application that is hosted on-premises to a cloud
architecture such as Amazon Web Services or Microsoft Azure. A significant
portion of the program has not been altered; nevertheless, it is now operating
in a new hosting environment, which allows it to take use of cloud features
such as scalability and flexibility.
