A company is planning to migrate its diverse workloads to Microsoft Azure. These workloads include both predictable, long-running applications that are critical to business operations and unpredictable, fault-tolerant batch processes that can handle interruptions. The company aims to optimize costs without compromising the availability of critical applications and to maintain the flexibility to handle sudden spikes in demand. Considering these requirements, which combination of Azure pricing models would BEST meet the company's needs? (Choose two options from the following five options.)
A
Implement Pay-as-you-go pricing for all workloads to ensure maximum flexibility and avoid any upfront commitments, despite higher long-term costs for predictable workloads.
B
Utilize Azure Reserved Instances for the predictable, critical workloads to secure significant cost savings over time, and apply Pay-as-you-go pricing for the unpredictable workloads to retain flexibility.
C
Adopt Spot Instances exclusively for all workloads to achieve the highest possible cost savings, accepting the risk of termination for both critical and fault-tolerant applications.
D
Combine Azure Reserved Instances for the stable, critical workloads to ensure uninterrupted service and cost efficiency, and use Spot Instances for the fault-tolerant, flexible workloads to capitalize on lower pricing where interruptions are acceptable.
E
Use Azure Hybrid Benefit for the critical workloads to reduce costs by leveraging existing on-premises licenses, and apply Pay-as-you-go pricing for the unpredictable workloads to maintain flexibility.
