What is our primary use case?
AWS Budgets is used for the internal FinOps experience, creating monthly cost budgets for AWS accounts and business units for tracking actual spend versus forecasted spend. The service sets thresholds to ensure spending does not exceed limits, sending alerts to the FinOps team, engineering, finance, and management teams. AWS Budgets also monitors specific cost categories and services using tags on linked accounts, supporting FinOps governance and cost accountability.
A recent purchase resulted in a spike in a particular cost category that sent an SNS notification to the FinOps distribution list, allowing the team to react, understand why the spike occurred, ask questions, and get useful information from the AWS team.
What is most valuable?
The best features AWS Budgets offers are the configuration capabilities for different limits on individual budgets, the tracking of actual spend against forecasted spend, and the ability to set thresholds. The notification service that is incorporated is very important, as is the visual interface and user experience that allows comparison of spending over previous months and forecasted views.
AWS Budgets has been used extensively in the implementation over the years with cost guardrails, and it helps significantly with the FinOps practice. AWS Budgets is straightforward to configure and provides timely notification when spending approaches predefined thresholds. The forecasting capability is valuable because it helps identify potential overruns before they occur. While AWS Budgets is effective for governance and alerting, it is combined with other tools such as Cost Explorer, cost and usage reports, and other FinOps reporting tools for rather detailed analysis and optimization. AWS Budgets is an overall valuable service for organizations beginning their FinOps journey and for maintaining cost accountability across teams.
What needs improvement?
There is limited visualization compared to Cost Explorer. Budget actions are useful but not as flexible as custom automations. Reporting can become difficult in large, multi-account organizations or environments. FinOps teams usually go to Crol, AWS Athena, or QuickSight for deeper analysis. Alerting fatigue can occur if thresholds are not carefully designed.
I rated this product eight out of ten because, similar to every service, there is room for improvement. If AWS Budgets could improve reporting for larger multi-account environments, enhance budget actions, and provide limited visualization improvements, the rating could be a ten. For now, the rating remains eight.
For how long have I used the solution?
AWS Budgets has been used for the past eight years.
What other advice do I have?
In my experience, AWS Budgets forecasting capabilities are generally accurate and reliable for workloads with stable or predictable spending patterns. The forecasts are useful for identifying potential budget overruns and triggering proactive alerts before costs exceed thresholds. However, accuracy can decrease significantly when there are sudden workload changes, seasonal spikes, new deployments, large-scale migrations, or unexpected consumption events. The forecasting should be viewed as a valuable guidance mechanism rather than a precise prescription or prediction. For critical financial planning or commitment decisions, AWS Budgets forecasts are typically validated with additional data sources such as Cost Explorer, Crol, and business forecasts. The accuracy is good for operational cost monitoring and governance but is not sufficient as the sole source for strategic financial forecasting.
To the best of my knowledge, AWS Budgets does not have AI capabilities at the moment. Regarding governance and security, the information manipulated by AWS Budgets can be sensitive because it represents the spending numbers tied to an organization. AWS does a good job in data residency and ensuring that this information is only located or used in the regions where the user has specified. The security of this data is controlled with IAM restrictions. In general, governance and security are under control, though there is no awareness of any AI capabilities.
AWS Budgets provides assurance that if there is going to be a spike, the entire team will be alerted, not just one person. This gives confidence that budgets will be maintained and that there is a good tool to help with analysis and understanding of how costs have evolved over time.
The team was able to respond in under five minutes to a budget alert that was quite alarming and was able to investigate and conduct follow-up interviews with support teams, demonstrating agility.
Setting up those notifications and thresholds was straightforward. There are about three setups for configuring the thresholds, and any user can find it easy to use and very intuitive, even if they are not an engineer.
AWS Budgets is essential. Starting with clear budget ownership and meaningful thresholds rather than creating too many budgets at once is important. AWS Budgets is most effective when aligned with business objectives, cost centers, applications, or teams. Setting forecast-based alerts at multiple levels, such as eighty, ninety, and one hundred percent, is recommended so teams have enough time to react before overspending occurs. I rate this review eight out of ten.
