AWS Cost Optimization through Rightsizing & Automation

**Get Detailed Case Study**Get Detailed Case Study

Project Overview:

In a recent project, AWS infrastructure audit revealed underutilized resources, misconfigurations, and a lack of automation, causing high costs. A structured optimization plan was implemented, including instance rightsizing and automation of non-production environments. Continuous monitoring and strategic savings plans were introduced to ensure long-term efficiency. Weekly reviews and audits were set up to maintain performance, avoid deprecated services, and track usage. These efforts led to significant cost savings while improving system stability and operational resilience.

Challenge:

Managing cloud infrastructure in a growing EdTech setup revealed multiple cost, security, and performance inefficiencies:

Underutilized EC2 Instances running at <20% capacity
Stopped EC2 & orphaned EBS volumes, still incurring charges
24x7 Test Environments without automation, active during off-hours
No Reserved Instances or Savings Plans, leading to high on-demand costs
Oversized RDS Instances with minimal usage
Outdated AWS Service Versions (e.g., RDS, Lambda), causing cost and compatibility issues

Solutions:

To reduce cloud costs and improve infrastructure efficiency, multiple cleanup, automation, and optimization strategies were implemented. These actions helped rightsize resources, automate non-critical environments, and prevent ongoing waste from idle components.

Terminated idle resources to cut waste.
Rightsized instances to match actual usage.
Automated test environment to avoid off-hour costs.
Bought Savings Plans for predictable workloads.
Set weekly audits for ongoing cleanup.
Upgraded services to the latest supported versions.
