IBM Cloud Analytics Engine decouples compute and storage to provide independent scaling and cost management capabilities. This approach allows organizations to scale compute resources (such as CPU and memory) separately from storage resources, optimizing both performance and cost.

Independent Scaling:Decoupling compute and storage means that users can scale the computational power (e.g., number of nodes, processing capabilities) independently of the storage capacity (e.g., data stored in IBM Cloud Object Storage). This is particularly useful in data analytics workloads where the compute requirements may vary significantly over time, but the storage requirements remain relatively constant.

Cost Control:By allowing compute and storage to be managed separately, users have greater flexibility to control costs. For example, users can increase compute power temporarily to handle a peak workload without the need to increase storage costs. Conversely, they can store large datasets without paying for unused compute capacity. This decoupling leads to a more cost-effective and efficient use of cloud resources.

Advantages in Cloud Environments:Decoupling compute and storage aligns with the best practices in modern cloud environments, where elasticity, scalability, and cost efficiency are paramount. It allows organizations to adapt quickly to changing business needs and workload demands, reducing overhead and improving resource utilization.

The most predominant aspect of an overall resiliency solution in IBM Cloud is "Addressing physical events." This refers to the ability to maintain service continuity and recover quickly from physical disruptions such as natural disasters (earthquakes, floods, fires, etc.). IBM Cloud provides multiple layers of resiliency, including geographic redundancy, data replication, backup, and disaster recovery services to ensure high availability and business continuity in the event of such physical events.

Physical Resiliency:IBM Cloud's strategy includes using multiple regions and availability zones to create a resilient infrastructure that can withstand physical events. By deploying applications across multiple zones and regions, the impact of a physical event is minimized.

Comprehensive Approach:Addressing physical events is part of a broader resiliency framework that also considers other types of failures (network, storage, etc.). Still, dealing with physical events like natural disasters is the most critical aspect of ensuring maximum protection and continuous operation.

Comparison with Other Options:

Storage requirements (A)andNetwork requirements (B)are important for overall performance but are not the primary aspect of resiliency.

Capture historical events (D)is related to logging and monitoring, not directly linked to resiliency from physical events.
