Which OCI service allows you to set financial controls and alerts for spending?

The service that allows you to set financial controls and alerts for spending within Oracle Cloud Infrastructure is Budgets. This service is designed specifically for managing and monitoring cloud spending. With Budgets, users can create financial budgets that define spending limits for their resources and services. Once you set up a budget, you can configure alerts that notify you when your spending approaches or exceeds the specified budget threshold. This proactive approach helps organizations stay on top of their expenses and manage their cloud resources effectively, ensuring that they do not overspend and can maintain financial oversight.

Monitoring focuses on the performance and availability of OCI resources rather than financial aspects. Events are used to manage and respond to changes in resource states but do not directly relate to financial management. Data Transfer pertains to the movement of data in and out of the cloud, including associated costs but does not provide spending alerts or budgetary control functionalities. These distinctions highlight why Budgets is the correct choice for managing financial controls and alerts in OCI.
