Start by looking at the breakdown of your costs in the cost analyzer. Look for the categories of your biggest spend. Is it storage? EC2? Something else? For storage; see if you can clean up things you don't need anymore. See if you can move infrequently used data into long-term, cheap storage (but beware retrieval costs!). For EC2, consider changing node types to cheaper ones. Newer classes are can be much better value for the money. Make sure you use spot instances where you can. Focus on the biggest expense first.
