AWS Budgets
AWS Budgets lets you set custom cost and usage budgets for your accounts. It tracks spending against those limits so you can see where money goes. The service operates on a pay-as-you-go model, meaning you only pay for what you use. There is no free tier available for this management tool.
It fits teams needing granular control over their cloud spend. You get concrete visibility into usage patterns without guessing. The main trade-off is the lack of a free tier. You will pay for the service itself, which adds a small overhead to your operational costs.
