How Can We Keep Our AWS Costs in Check as We Scale?

Monitoring actual costs daily was a game changer for us. We also opted against auto-scaling, which helped us manage costs effectively without compromising our service delivery. It won’t fit everyone, but it's worked for our business model.

From my experience in larger SaaS companies, focusing on resource allocation and reducing cross-regional network costs has saved us a lot down the line. Often teams overlook network charges early on, but addressing them can cut significant cloud expenses later.

It's all about knowledge and having a team that’s eager to learn. Investing in a few certifications can save a ton on costs. Besides that, automating resource management with sensible limits and timeout settings for queries on Athena and Glue can prevent surprise bills.

Definitely make tagging mandatory! Setting up billing alerts for abnormal cost anomalies is crucial. You might also want to consider using IaC and tools like Karpenter for EKS to optimize resource management. A solid FinOps tool can provide visibility into costs and usage trends, which is super helpful as you grow.

One of the best strategies is to set up AWS Budgets so you get alerts when you hit 50% and 80% of your monthly limit. Also, regularly checking the Cost Explorer can help track which services are costing more than expected, especially when you group expenses by service and your tags.
