Which service in OCI provides automatic adjustments based on demand?

The service that provides automatic adjustments based on demand is Autoscaling. This feature is designed to ensure that the performance of compute resources adapts dynamically to varying workloads. It automatically increases or decreases the number of compute instances based on predefined policies, such as CPU utilization or other metrics, ensuring that applications remain responsive while optimizing resource usage and costs.

By employing autoscaling, organizations can maintain application performance during peak loads without manual intervention, and conversely, reduce resources when demand decreases, resulting in cost savings and efficiency. Autoscaling is particularly useful in cloud environments, where demand can change rapidly and unpredictably.

The other options listed serve different purposes. Cost Management focuses on tracking and optimizing cloud spending, the Load Balancer distributes incoming traffic across multiple resources to ensure reliability and high availability, and Data Science is a service aimed at enabling data scientists to collaborate effectively on analytics projects. While these services play important roles in cloud architecture, none of them provide the automatic, demand-based adjustments that autoscaling does.
