Use the AWS Cost Explorer to analyze your instance usage. Selecting the right instance type can significantly reduce costs.

Use Reserved Instances

Reserved instances offer significant discounts compared to on-demand instances. Reserve instances for workloads that have predictable usage. You can save up to 75% compared to on-demand pricing. Analyze your workload patterns to identify suitable candidates for reserved instances. Reserved instances are a great way to save money on your long-term infrastructure needs.

Leverage Spot Instances

Spot instances allow you to bid for unused EC2 instances at a significant discount. Use spot instances for fault-tolerant workloads that can withstand interruptions. Spot instances can save you up to 90% compared to on-demand pricing. Monitor spot instance pricing and adjust your bids accordingly. Spot instances are a great way to save money on non-critical workloads.

Optimize Storage Costs

Choose the right storage service for your needs. Use Amazon S3 for object storage and Amazon EBS for block storage. Use lifecycle policies to move data between different storage classes, such as from standard to infrequent access to glacier. Regularly review your storage usage and identify opportunities for optimization. Optimizing storage costs can result in significant savings.

Right-Size Your Resources

Regularly review your resource usage and right-size your instances and storage. Use AWS CloudWatch to monitor your resource utilization. If you're using more resources than you need, downsize to a smaller instance type. If you're using fewer resources than you need, consider resizing. Right-sizing ensures that you're only paying for the resources you use.

Use AWS Cost Explorer and Budgets

AWS Cost Explorer helps you visualize your spending and identify areas for optimization. Set up budgets to track your spending and receive alerts when you exceed your budget. Use cost allocation tags to track costs by department or project. Utilizing these tools allows for better cost management and control.

Automate and Script Your Infrastructure
