Implementing Recommendations for Cost Savings
Applying AWS Trusted Advisor’s recommendations can lead to substantial cost savings by optimizing resource usage and eliminating waste.
1. Right-Sizing Instances
Optimize Instance Sizes
- Trusted Advisor analyzes your EC2 instances to identify those that are underutilized or overprovisioned. Based on actual usage patterns, the right size is recommended for these instances.
- You can significantly reduce your computing costs by resizing instances to match their workload.
Example: If an m5.large instance consistently uses only a fraction of its available CPU and memory, Trusted Advisor might recommend switching to an m5.medium instance, cutting costs by nearly half.
2. Deleting Unused Resources
Remove Idle Resources
- Trusted Advisor helps you identify and remove unused or idle resources, such as unattached EBS volumes, outdated snapshots, or inactive load balancers.
- Deleting these unused resources prevents unnecessary charges and frees up capacity.
Example: Identify and delete unattached EBS volumes that continue to incur storage costs even though they are not used.
3. Purchasing Reserved Instances and Savings Plans
Commit to Long-Term Usage
- Trusted Advisor provides insights into your instance usage patterns and recommends purchasing Reserved Instances (RIs) or Savings Plans for workloads with consistent usage. These commitments can offer significant discounts compared to On-Demand pricing.
- Evaluate the potential savings and commit to the appropriate level of reserved capacity.
Example: If you have several T3, a trusted advisor might recommend purchasing a one-year or three-year reserved instance plan for medium instances that run consistently to save up to 72% on your computing costs.
4. Leveraging Spot Instances
Use Spot Instances for Flexible Workloads
- Trusted Advisor can suggest using Spot Instances for fault-tolerant workloads that can handle interruptions, such as batch processing or data analysis tasks.
- Spot Instances offer steep discounts compared to On-Demand prices, providing significant cost savings for suitable workloads.
Example: Run your data processing jobs on Spot Instances, which can be up to 90% cheaper than On-Demand Instances, significantly lowering your compute costs.
5. Optimizing S3 Storage Classes
Choose the Right Storage Class
- Trusted Advisor reviews your S3 storage usage and recommends moving infrequently accessed data to cheaper storage classes, such as S3 Standard-IA (Infrequent Access) or S3 Glacier.
- You can reduce storage costs by aligning your data storage needs with the appropriate S3 storage class.
Example: Move infrequently accessed backup files from S3 Standard to S3 Glacier, reducing storage costs by up to 80%.
6. Terminating Idle Load Balancers
Remove Unnecessary Load Balancers
- Trusted Advisor identifies load balancers with low or no traffic that may no longer be needed. Terminating these idle load balancers can eliminate unnecessary costs.
- Regularly review and terminate load balancers that are not actively managing traffic.
Example: Terminate an Elastic Load Balancer (ELB) that has had zero traffic for the past month, saving on hourly charges and data processing fees.
7. Consolidating Underutilized Resources
Combine Low-Utilization Instances
- Trusted Advisor suggests consolidating multiple low-utilization instances into fewer, more efficiently utilized instances. This consolidation helps optimize your resource usage and reduce costs.
- Evaluate workload requirements and combine instances where feasible to improve utilization.
Example: Merge workloads from multiple underutilized t2.micro instances into a single, appropriately sized t3.small instance, reducing the number of active instances and associated costs.
8. Reviewing AWS Marketplace Subscriptions
Evaluate Third-Party Services
- Trusted Advisor reviews your AWS Marketplace subscriptions and identifies any that are not being utilized or are underutilized. Canceling these subscriptions can save costs.
- Regularly review and manage your third-party service subscriptions to ensure they align with your current needs.
Example: Cancel a software subscription from AWS Marketplace that is no longer in use, eliminating recurring monthly fees.
9. Enabling Auto Scaling
Automate Resource Scaling
- Trusted Advisor recommends configuring Auto Scaling to dynamically adjust the number of instances based on demand. This ensures that you are not paying for unused capacity during low-traffic periods.
- Implement Auto Scaling policies to match your resource allocation with actual usage patterns.
Example: Configure Auto Scaling for your web application to scale during off-peak hours and out during high-traffic periods, optimizing cost and performance.
10. Utilizing Cost Allocation Tags
Track and Manage Costs
- Trusted Advisor highlights the importance of using cost allocation tags to categorize and track your AWS spending. By appropriately tagging resources, you can gain better visibility into costs and identify opportunities for savings.
- Implement a tagging strategy to allocate costs accurately and analyze spending trends.
Example: Tag all resources by project, department, and environment (e.g., Project: WebsiteRedesign
, Department: Marketing
, Environment: Production
) to track and optimize costs effectively.
