How does AWS Cost Explorer assist users?

AWS Cost Explorer is a powerful tool that assists users by analyzing and visualizing cost data associated with their AWS resources. It allows users to view and understand their spending patterns over time, enabling them to identify trends, set budgets, and forecast future costs. With functionalities like filtering costs by service, resource tags, or linked accounts, users can gain deeper insights into where their expenses are occurring. This data visualization helps in making informed decisions regarding resource allocation, budget management, and cost optimization strategies, ultimately leading to more effective financial management in the cloud.

The other options do not relate to the primary purpose of AWS Cost Explorer. Application hosting, network access management, and automated security assessments are not features of Cost Explorer; instead, they fall under different services and functionalities within the AWS ecosystem. These services address specific needs outside of cost management and analysis.
