The company also needs a dedicated, private network connection between the two environments for low latency and security. Which cloud deployment model best describes this architecture?

A company runs a monthly data processing job that requires 100 Amazon EC2 instances to complete within 4 hours. The job is not needed at any other time. The company previously ran this job on its on-premises servers, which required maintaining enough capacity to handle the peak load year-round, leading to low average utilization. The company has now migrated the job to AWS. Each month, the company automatically provisions the 100 instances, runs the job, and then terminates the instances. Which essential characteristic of cloud computing does this scenario best illustrate?

A company is moving its on-premises workloads to AWS.
