Cloud cost optimization is the continuous practice of reducing cloud expenditures while maintaining or improving performance, reliability, and business value across AWS, Azure, Google Cloud, and other cloud platforms. It encompasses strategic approaches ranging from commitment-based discounts and resource rightsizing to automated waste elimination and real-time cost governance. As organizations increasingly adopt multi-cloud and AI workloads in 2026, cost optimization has evolved from periodic reviews to continuous, automated control loops that tie cloud spending directly to unit economics and business outcomes. The most successful strategies combine technical optimization (right-sizing, spot instances, storage tiering) with organizational practices (FinOps culture, showback/chargeback, budget enforcement) and platform-native tools (AWS Compute Optimizer, Azure Cost Management, GCP Active Assist).

Table 1: Commitment-Based Pricing Models

Strategy	Example	Description
Reserved Instances	`EC2 Standard RI:` `1-year, 72% discount` `Instance type locked`	Long-term commitment (1-3 years) for specific instance types offering deep discounts but limited flexibility across instance families or regions.
Savings Plans	`Compute SP:` `$10/hour commit` `Any instance family/region`	• Flexible pricing model offering up to 72% savings based on dollar-per-hour commitment • automatically applies to EC2, Fargate, Lambda across instance families and regions.
Spot Instances	`60-90% discount` `Interruptible workloads` `Use 10+ instance types`	• Spare capacity at massive discounts but can be preempted with 2-minute warning • ideal for fault-tolerant batch jobs, CI/CD, data processing.
Preemptible VMs	`GCP: up to 91% off` `24-hour max runtime` `No SLA guarantees`	• Google Cloud's interruptible instances offering deepest discounts but limited to 24-hour sessions • requires checkpoint/restart logic.
