AWS instance right-sizing optimization

The Cost of Over-Provisioned Instances

Many organizations run AWS instances that are significantly over-provisioned for their actual workload demands. This results in paying for compute capacity that goes unused, directly impacting your cloud budget. Right-sizing ensures your infrastructure matches your real-world requirements.

Instances selected for peak load but running at 10-20% utilization on average
Legacy instance types that are more expensive than newer generation alternatives
Lack of visibility into actual CPU, memory, and network usage patterns
No regular review process to adjust sizing as workloads change

Key Benefits of Instance Right-Sizing

Optimize your compute costs while maintaining or improving application performance

Significant Cost Reduction

Reduce monthly AWS bills by 20-40% by matching instance types precisely to actual workload demands and eliminating over-provisioning.

Improved Performance

Optimize instance selection for specific workload types, often improving performance while reducing costs through better resource allocation.

Better Resource Visibility

Gain complete insight into CPU, memory, network, and storage utilization patterns across your infrastructure.

Continuous Optimization

Establish ongoing monitoring processes to ensure instance sizes adapt to changing workload demands over time.

Our Right-Sizing Approach

Comprehensive Utilization Analysis

Understand Your Current Resource Usage

We analyze CPU, memory, network I/O, and storage metrics from CloudWatch to understand actual usage patterns. This data-driven approach reveals which instances are over-provisioned and by how much.

Review 30-90 days of CloudWatch metrics for patterns
Analyze peak, average, and minimum usage across all dimensions
Correlate utilization with business metrics and traffic patterns
Identify instances that are candidates for downsizing

Instance Type Optimization

Select the Perfect Match for Your Workloads

AWS offers numerous instance types optimized for different use cases. We recommend the most cost-effective instance types that meet your performance requirements, including newer generation options with better price-to-performance ratios.

Evaluate instance family options (general purpose, compute, memory, storage optimized)
Compare price and performance across instance generations
Consider burstable instances (t3, t4g) for variable workloads
Leverage graviton processors for significant cost savings

Implementation & Monitoring

Execute with Minimal Disruption

We implement right-sizing changes strategically to minimize or eliminate downtime. For production environments, we use rolling updates and Auto Scaling groups. We then establish continuous monitoring to ensure ongoing optimization.

Create detailed implementation plan with zero-downtime migration strategies
Test changes in non-production environments first
Monitor performance metrics post-migration to validate improvements
Establish quarterly review process for ongoing optimization

Understanding AWS Instance Types

AWS offers diverse instance types optimized for different workload characteristics and use cases

General Purpose (t3, m5, m6i, m7i)

Balanced compute, memory, and networking for web servers, small databases, and development environments. Great starting point for most workloads.

Compute Optimized (c5, c6i, c7g)

High-performance processors for batch processing, scientific simulations, and CPU-intensive applications. Best price-to-performance for compute-heavy workloads.

Memory Optimized (r5, r6i, r7i, x1)

High memory capacity for in-memory databases, caches, and real-time analytics. Ideal for workloads requiring low-latency data access.

Storage Optimized (i3, d2, h1)

High I/O performance for NoSQL databases, data warehousing, and Elasticsearch. Provides optimized storage throughput.

Accelerated Computing (p3, g4, f1)

GPU, FPGA, and inference accelerators for machine learning, GPU rendering, and specialized applications. Premium pricing for specialized workloads.

Burstable Instances (t3, t4g)

Cost-effective for variable workloads with periods of high and low utilization. Earn CPU credits during low-usage periods and burst when needed.

Right-Sizing Implementation Roadmap

1

Assess Current Instances

Inventory all EC2 instances with their types, sizes, configurations, launch dates, and current CloudWatch utilization metrics.

2

Analyze Utilization Patterns

Collect 30-90 days of CPU, memory, network, and storage metrics. Identify peak, average, and minimum usage patterns.

3

Identify Optimization Candidates

Classify instances into categories: optimized, underutilized, or significantly over-sized. Calculate potential savings.

4

Recommend New Instance Types

Propose right-sized instances that meet performance requirements while minimizing costs. Compare with current spending.

5

Plan Migration Strategy

Develop implementation plan considering dependencies, Auto Scaling groups, load balancers, and minimal downtime approaches.

6

Execute Right-Sizing

Implement changes in phases starting with non-production. Verify performance and cost improvements before full rollout.

7

Monitor and Validate

Track performance metrics post-migration. Confirm cost savings match projections. Address any performance issues.

8

Establish Ongoing Reviews

Schedule quarterly reviews to reassess sizing as workloads change. Update thresholds based on business needs.
