An organization wants to create a new application in the cloud to (Digital Leader)

Correct answer: D) Invent in brownfield.
The best approach for an organization looking to replace an existing on-premises application with a new application in the cloud depends on several factors, including the complexity of the existing application, the desired features and performance of the new application, and the organization's resources and expertise. However, based on the options provided:

A) Move the application to the cloud, and then change it. This approach involves migrating the existing application to the cloud and then making necessary changes to adapt it to the cloud environment. This can be a good option if the organization wants to minimize disruption and leverage existing knowledge and infrastructure. However, it might not fully utilize the cloud's capabilities and could lead to a less optimal solution.

B) Change their application, and then move it to the cloud. This approach involves first modifying the application to better suit the cloud environment and then moving it to the cloud. This can lead to a more optimized solution that takes full advantage of cloud capabilities, but it requires a significant investment in time and resources to redesign the application.

C) Invent in greenfield. This approach involves designing and developing a new application from scratch in the cloud environment. This can be the most efficient way to create an application that is optimized for the cloud, but it requires a significant investment in time and resources, and there's a risk of not fully addressing the needs of the existing application.

D) Invent in brownfield. This approach involves modifying the existing application to better suit the cloud environment and then moving it to the cloud. This can be a good balance between leveraging existing knowledge and infrastructure and creating a cloud-optimized solution.

Given the context of replacing an existing on-premises application with a new application in the cloud, the most suitable approach would likely be D) Invent in brownfield. This approach allows the organization to leverage the existing application's knowledge and infrastructure while also making necessary changes to adapt it to the cloud environment. This can lead to a more efficient and cost-effective solution compared to starting from scratch (greenfield) or moving the application without changes (A).
