The objective of continuous cost optimization in OCI is to maximize business value while minimizing costs. Accurate usage and cost data is essential for the optimization process, which can be obtained through various channels such as UI, CSV files, and API calls. Cost optimization is an iterative process driven by data and analysis, with the goal of eliminating idle resources that incur costs without delivering value. To understand the cost of a solution in OCI and optimize it, structured collection of usage and performance metrics is necessary. OCI provides a large amount of metrics, but it is important to use available tools to structure the data and set up alerts for spending increases or underutilized resources.
