Amazon 10 BEST PRACTICES FOR REDUCING SPEND IN AWS
- Best practices are to delete a volume when it has been unattached for two weeks, as it is unlikely the same volume will be utilized again.
- One way of finding snapshots that are good candidates for deletion is to identify the snapshots that have no associated volumes. When a volume is deleted, it’s common for the snapshot to remain in your environment. Be careful not to delete snapshots that are being utilized as a volume for an instance
- DELETE DISASSOCIATED ELASTIC IP ADDRESSES
- TERMINATE ZOMBIE ASSETS: Start your zombie hunt by identifying instances that have a Max CPU%
- UPGRADE INSTANCES TO THE LATEST GENERATION
- RIGHTSIZE EC2 INSTANCES & EBS VOLUMES: A good starting place for rightsizing is to look for instances that have an Avg CPU < 5% and Max CPU < 20% for 30 days. Instances that fit this criteria are viable candidates for rightsizing or termination.
- STOP AND START INSTANCES ON A SCHEDULE: Set a target for weekly hours that non-production systems should run. One large publishing company set that target at less than 80 hours per week, which is saving them thousands of dollars a month.
- BUY RESERVED INSTANCES ON EC2, RDS AND AUTOMATE OPTIMIZATION: A 1-year term reservation will almost always breakeven after six months. This is when you can shut down an instance and still benefit from the reservation’s pricing discount. For a 3-year reservation, the break-even point usually occurs around nine months.
- BUY RESERVED NODES ON REDSHIFT AND ELASTICACHE
- MOVE OBJECT DATA TO LOWER-COST TIERS: Best practice is that any objects residing in S3 that are older than 30 days should be converted to S3 Infrequent Access. While standard storage class pricing is tiered based on the amount of content within the bucket, with a minimum price of $0.0275 per GB per month, Infrequent Access storage remains consistent at $0.0125 per GB per month.
