Final answer:
The Amazon Machine Image (AMI) is used to launch EC2 instances on the AWS Cloud; EBS volumes and snapshots serve as storage, and Amazon VMware enables a hybrid environment but does not launch instances.
Step-by-step explanation:
The Amazon Machine Image (AMI) is used to spin up EC2 instances on the AWS Cloud. An AMI is essentially a template that contains the software configuration (operating system, application server, and applications) required to launch an EC2 instance. While EBS volumes and snapshots can be associated with an EC2 instance, they are used for storage purposes and are not capable of launching an instance on their own. Amazon VMware is not directly used to launch EC2 instances; instead, it is a service that enables users to run a seamless hybrid environment with VMware-based infrastructure. Therefore, the correct answer for spinning up an EC2 instance is the Amazon Machine Image.
