1. Safe Workload Allocation on Spot Instances
Spot/Preemptible instances offer discounts up to 70–90% compared to on-demand pricing in exchange for potential 2-minute interruption notices. Stateless web pods, asynchronous worker queues, and batch jobs thrive on Spot fleets.
Use Karpenter or AWS EC2 Auto Scaling groups with capacity-optimized allocation strategies to diversify across multiple instance families (e.g. m5, m6i, c5, c6i), virtually eliminating concurrent terminations.
2. Storage Tiers and Orphaned Resource Audits
Unattached Elastic Block Store (EBS) volumes left behind after EC2 deletions and old unversioned S3 buckets quietly consume thousands of dollars. Enable S3 Intelligent-Tiering and transition EBS volumes from legacy gp2 to gp3 for an instant 20% cost savings with higher baseline IOPS.
