How can one move applications from one EC2 instance to another with a different instance type?

1. Directly change the instance type in the EC2 management console

2. Stop the original instance and modify its settings

3. Create an AMI of the instance and launch a new instance from it

4. Use Elastic Beanstalk for deployment

The correct answer is: Create an AMI of the instance and launch a new instance from it

Creating an Amazon Machine Image (AMI) of the instance and launching a new instance from it is the correct method to move applications from one EC2 instance to another with a different instance type. When you create an AMI, it captures the state of your instance, including the operating system, application configurations, and any data on the instance's volumes. This allows you to create an exact replica of your original instance, which can then be launched as a new EC2 instance with a different instance type. By selecting a different instance type during the launch process, you can take advantage of varying resource configurations suited to your application’s needs. Launching a new instance from an AMI ensures you have a consistent configuration, while also giving you the flexibility to select the appropriate capacity and performance characteristics based on your requirements. This method is particularly useful for scaling applications or transitioning to a different instance type without the need to manually replicate all settings and configurations. While the other options may seem viable, they do not effectively address the requirement of moving applications between instances with different configurations. Changing the instance type directly in the management console does not apply here because it does not facilitate transferring applications between separate instances, especially if the types differ. Stopping the instance and modifying its settings might
