Cloud computing promises cost savings, but without governance it can become a money pit. Here are five mistakes we see constantly.
1. Running instances 24/7 for 9-to-5 workloads
Dev and staging environments that run around the clock waste thousands per year. Schedule them to shut down outside business hours — AWS Instance Scheduler makes this trivial.
2. Ignoring Reserved Instances and Savings Plans
On-demand pricing is the most expensive tier. If you have predictable baseline usage (and most do), committing to a 1-year Savings Plan can cut compute costs by 30–40%.
3. Oversized instances
That m5.4xlarge running at 8% CPU utilization? It should probably be a t3.medium. Use AWS Compute Optimizer or a similar tool to right-size your fleet.
4. Forgetting about data transfer costs
Data transfer between regions, to the internet, and even between AZs adds up fast. Architect your services to minimize cross-region traffic and use CloudFront to cache content at the edge.
5. No tagging strategy
If you can't attribute costs to teams or projects, you can't optimize them. Implement a tagging policy on day one: at minimum, tag by environment, team, and project.
The fix is simpler than you think
A structured cost review — even once a quarter — can save 30% or more. We offer free audit calls to help SMBs identify their biggest savings opportunities.
