Cloud spending has risen significantly alongside the adoption of AWS, Azure, and GCP services, which drive business operations. Cost management, however, becomes the top priority as businesses scale their usage. The waste brought by inefficient spending can rise to 30% according to a flexera report. Meeting this challenge requires understanding the two complementary approaches to cost savings: rate optimization and usage optimization.
This blog aims to equip cloud professionals with actionable insights on managing expenses by breaking down these strategies.
What Is Cloud Cost Optimization?
The intention behind cloud cost optimization is to reduce the cloud’s expenses while maintaining or improving the performance and availability simultaneously. Which further divides into two considerations:
Usage Optimization: Trim down the systems operated to the extent of the services actually needed.
Rate Optimization: Leverage discounts, pricing models, and agreements to run workloads at a lesser cost, which also includes negotiating lower rates, purchasing reserved capacity, and finding opportunities for savings to minimize operating expenses
Usage optimization aims to address resource efficiency, and rate optimization is a financial approach directed at minimizing expenses without sacrificing the level of service provided.
Why Both Rate and Usage Matter
Optimizing cost in the cloud does not translate to simply reducing expenses; it means achieving a high level of operational ‘efficiency.’ Attempting to cut costs on a per-unit basis through rate optimization may result in increasing expenses due to inefficiencies in usage. On the opposite end of the spectrum, improving usage without obtaining better rates is also not ideal, as it caps the potential for savings.
If integrated appropriately, rate and usage optimization enable organizations to achieve sustainable cost efficiencies, enhanced operational effectiveness, and improved ROI in the cloud.
What Is Cloud Rate Optimization?
Cloud resource scaling is an automated process for eliminating ineffective processes by dynamically provisioning and releasing cloud resources in relation to the current demand. Rate optimization entails achieving the lowest price per unit for the cloud resources you use, confined to the billing layer of your business. It uses pricing models, discounts, and payment commitments to optimize expenses without changing consumption levels.
Common Rate Optimization Strategies by Cloud Provider:
AWS:
Reserved Instances: Commit to instance usage for 1 or 3 years to save up to 72%.
Savings Plans: Flexible savings options on compute usage across services like EC2 and Fargate.
Spot Instances: Use spare capacity for interruptible workloads and save up to 90%.
Azure:
Reserved VM Instances: Get discounted pricing for predictable workloads with long-term commitments.
Azure Hybrid Benefit: Reuse existing licenses such as Windows Server and SQL Server to cut costs significantly.
GCP:
Committed Use Discounts: These are available to those who commit to a certain level of resource usage for 1 or 3 years.
Sustained Use Discounts: Automatically save as your usage grows within a billing cycle.
Benefits of Rate Optimization:
Lower Costs: Reduce expenses with no changes to architecture.
Predictable Spend: Commitments create cost clarity.
Quick Wins: Immediate savings through smarter billing.
Although rate optimization requires continual monitoring to ensure no overspending occurs or usage alignments don’t drift. Thoughtful oversight guarantees the full realization of these strategic cost-saving measures.
What Is Cloud Usage Optimization?
Like all technologies, cloud usage resources can be optimized by ensuring their efficient and effective usage. Optimization does not only focus on the cost-per-unit metric - it goes beyond that to usage patterns and aims to reduce avoidable costs while maximizing returns on investments made on the cloud infrastructure.
Key Strategies for Cloud Usage Optimization:
AWS
Right-Sizing EC2 Instances: Resize EC2 instances to the idle state when performance metrics are consistently low.
Eliminating Idle EBS Volumes: Delete unused storage to alleviate unnecessary costs.
Auto-Scaling: Adjust resources automatically in real time based on the workload demand.
Azure
Shutting Down Unused VMs: Disable virtual machines that are idle and not performing useful work to minimize costs.
Storage Tiering: Move rarely accessed data to lower-cost storage tiers for better cost efficiency.
GCP
Preemptible VMs: Use low-cost, short-lived VMs for fault-tolerant workloads to save money.
Workload Automation: Automate scaling and operational tasks for seamless resource management.
Core Principles of Cloud Usage Optimization:
Right-Sizing: Align cloud instances, storage, and resources with the exact needs of your workloads.
Eliminate Waste: Identify and remove unused or idle resources, such as dormant VMs, unattached storage, or over-provisioned instances.
Leverage Automation: Use tools like AWS Auto Scaling, GCP Recommendations Hub, and Azure Advisor to automate resource provisioning and identify areas that can be refined further.
Usage Optimization Benefits:
Reduces inefficiencies.
Realigns resources based on workload demand.
Promotes a dynamic architecture that adapts flexibly to business needs.
Rate vs Usage Optimization at a Glance
Criteria | Rate Optimization | Usage Optimization |
Objective | Lower cost per unit of resources | Reduce resource consumption |
Focus | Financial agreements, pricing models | Architectural improvements |
Strategies | Reserved Instances, Savings Plans, CUDs | Right-sizing, eliminating waste |
Impact | Reduces costs without architectural changes | Improves efficiency across cloud architecture |
Flexibility | Requires long-term commitments | High flexibility with real-time adjustments |
Best For | Predictable workloads | Variable or dynamic workloads |
Best Practices to Implement an Optimization Strategy
1. Review Your Cloud Usage and Spend
Look at your cloud spend analysis and try to determine if there are any inefficiently utilized resources that may still be costing you money. Services like AWS Cost Explorer and Azure Cost Management can be of great assistance in analyzing where spending is coming from.
2. Start with Usage Optimization
Start by addressing inefficient usage:
Right-size workloads using tools like AWS Compute Optimizer.
Get rid of unused resources such as idle VMs and orphaned volumes.
Automate scaling and resource allocation to enhance efficiency.
3. Layer on Rate Optimization
Once your usage patterns are streamlined, implement rate optimization strategies to reduce costs:
Reserved Instances (RIs): Lock in discounts (up to 72%) for specific instances.
Savings Plans: Enjoy flexible discounts (up to 66%) for any instance within a family.
Group Buying: Use Pump to pool commitments with other companies for AWS/Azure/GCP discounts—no upfront cost.
Spot/Preemptible Instances: Deploy for fault-tolerant workloads and save 60–90%.
4. Enable Continuous Monitoring
Dynamically monitor spending and usage patterns in real-time using dashboards and reporting tools set for your automated cloud spend goals, such as those provided by Pump or native tools from AWS, Azure, and GCP. Set tracking goals and automate them to see progress.
5. Iterate Regularly
Cloud implementations have shifting limits. Improve your spending and usage strategies on a regular basis as workloads or technologies change across different pricing models:
Forecast Demand: Use machine learning to predict usage spikes and adjust commitments accordingly.
Monthly Reviews: Hit refresh, run the optimization scripts again, and adjust tactics to remain aligned with the targets.
Adopt FinOps: Align cloud spending with business metrics like cost per customer for better financial management.
Why Balance Rate and Usage Optimization?
To balance your cloud costs, focus on both rate and usage optimization. This is why each is equally important:
1. Rate Optimization Alone Isn’t Enough
What it does: Reduces your price per unit such as discounts or special pricing.
The catch: If you’re still paying for unused resources, you’re just getting a discount on waste.
2. Usage Optimization Alone Isn’t Enough
What it does: Guarantees you are only using the resources you truly need.
The catch: Even with efficient usage, you might still overpay if you haven’t secured better rates.
3. The Real Savings Come From Doing Both
When you optimize usage: Eliminate waste for everything that’s paid for.
When you optimize rates: Get the lowest price for those resources.
This way, you avoid getting different resources than what you need while paying the correct amount.
Hope you take action, leverage advanced tools like Pump to optimize your cloud environment, and grow your business by making the most of your cloud spend.
