B. Loose coupling
C. Disposable resources
B. Loose coupling: This principle refers to the ability to design and operate the different components of a workload independently of each other, so that changes in one component do not affect the others. This allows for more flexibility and scalability in the design and operation of the workload.
C. Disposable resources: This principle refers to the ability to quickly and easily provision, scale, and dispose of resources as needed. This allows for more efficient use of resources and can improve the overall cost-effectiveness of the workload.
D. Server design and concurrency: This principle refers to the ability to design and operate servers and workloads with high concurrency and parallelism, but it is not enabled by the AWS cloud.
B. Loose coupling
C. Disposable resources
Loose coupling: AWS allows for the creation of decoupled components within an architecture. This principle enables systems to be built with loosely coupled components, reducing dependencies between different parts of the system and allowing for greater flexibility, scalability, and resilience.
Disposable resources: AWS Cloud facilitates the concept of disposable or ephemeral resources, enabling the creation and destruction of resources as needed. This supports the idea of creating resources on-demand, scaling up or down, and decommissioning resources when they are no longer required. This approach can save costs and improve efficiency.
B. Loose coupling: AWS allows you to design your applications in a loosely coupled manner, where components are decoupled and communicate with each other through APIs. This promotes flexibility, scalability, and easier maintenance of your applications.
C. Disposable resources: AWS allows you to treat infrastructure as code and create and destroy resources as needed. This concept of "disposable resources" enables you to respond dynamically to changes in demand, scale your resources up or down, and replace failing instances easily.
WS Cloud offers several design principles that improve the operation of workloads. Two of those principles are:
B. Loose coupling: Services should be designed to be loosely coupled. A loosely coupled system is one where each component is independent and does not rely on other components to function correctly.
C. Disposable resources: Design systems that expect and tolerate failure. In the cloud, there is no need to repair failed components. Simply shut them down and replace them with new ones. This design principle is often called "disposable resources."

C. Disposable resources
The AWS Cloud enables a number of design principles that can help to improve the operation of workloads. Two of these principles are loose coupling and disposable resources.
