Hey there, I know clouds and their bills might be hectic.. Even though a lot of information in your case is lacking, here are a few tips for you to consider:
-Get to know the AWS instances, their types and find the ones that could do the the same job - but better. Here at CAST we benchmarked a lot of instances and select the best ones for you.
-Reconsider spot instances - as "advertised" they really do save up to 90% if you are lucky enough to bid low for an instance that is currently in not such a big demand.
-Are you a kubernetes user? If so, do you have HPA and VPA configured and running smoothly ?
-If you're an EKS / GKE /kOps user, Give us - CAST, a shot, I know it's a bold claim, but if you invest a minute to visit https://cast.ai - the ROI can be massive. We've had companies in e-commerce, martech and development services save anywhere in the range from $50,000 to $1,700,000 per year with CAST AI.
To be completely truthful, some of them cut 40%+ on their bill with the information from our free report alone.
-And of course, go trough that AWS bill in detail, check and cross out what's a low hanging fruit. Also check whether some workloads do have to be running at night.
