An organization has decided to modernize their applications in the (Digital Leader)

Correct answer: D) Their on-premises applications take months to update and deploy.
Here's why:

A) On-premises applications only autoscale to meet demand is not a compelling reason to migrate to the cloud. Autoscaling is a feature that can be implemented in both on-premises and cloud environments.

B) Changing from a pay-as-you-go model to a capital expenditure model is not typically a primary driver for modernizing applications in the cloud. In fact, the pay-as-you-go model of cloud computing often provides more flexibility and cost savings compared to traditional capital expenditure models.

C) Source code changes erroneously without developer interaction might indicate a need for better version control or automation in the software development process, but it's not a direct prompt for migrating to the cloud.

D) On-premises applications taking months to update and deploy is a common pain point that organizations experience due to limitations in infrastructure, processes, and resources. Migrating to the cloud allows for more agile development and deployment practices, reducing the time it takes to update and deploy applications. This aligns with the goal of keeping up with customers' needs, as faster updates and deployments enable organizations to deliver new features and improvements more quickly.

Therefore, option D) Their on-premises applications take months to update and deploy is the most likely reason prompting the business decision to modernize their applications in the cloud.
