A retail company is migrating its IT infrastructure applications from on premises to the AWS Cloud. Which costs will the company eliminate with this migration? (Select TWO.)

Migrating from an on-premises data center to the AWS Cloud allows a company to trade large capital expenses for variable operational expenses. The company eliminates the need to purchase and maintain physical server hardware. It also eliminates the costs associated with running a physical data center, such as power, cooling, physical security, and real estate. AWS manages the physical infrastructure, allowing the company to focus on its applications and customers rather than on managing hardware and facilities.

B. Cost of application licensing is not necessarily eliminated; companies may still need to pay for software licenses, although they can sometimes leverage a bring-your-own-license (BYOL) model or purchase licenses through AWS Marketplace.
C. Cost of marketing campaigns is a business expense unrelated to IT infrastructure and is not affected by a cloud migration.
E. Cost of network management is not eliminated but shifted; companies still manage their virtual network (VPC) but no longer manage physical network hardware.
