Detailed cost analysis
We started with a thorough analysis of AWS billing and usage reports to identify high-cost resources and services. AWS Cost Explorer and AWS Budgets provided insights into our spending patterns, helping us pinpoint areas for cost reduction.
Right-sizing and reserved instances
- Right-sizing: We analyzed our EC2 instances and RDS databases to identify over-provisioned resources. By right-sizing these resources to match actual usage, we significantly reduced our monthly AWS costs.
- Reserved instances: For predictable workloads, we purchased Reserved Instances, achieving substantial savings over on-demand pricing.
Cleanup and decommissioning
We implemented a process to regularly review and decommission unused or idle resources, such as unattached EBS volumes and obsolete snapshots, which contributed to cost savings.
Cost allocation tags and monitoring
We implemented detailed tagging for all our resources, enabling precise tracking of costs by department, project, and environment. This facilitated more informed budgeting decisions and accountability.
Continuous monitoring and optimization
AWS Trusted Advisor and third-party tools were utilized for ongoing monitoring and recommendations on cost optimization, security, and performance.
