AWS Cost best practices for EBS

Amazon Elastic Block Store (EBS) is a high-performance block storage service designed to attach persistent storage volumes to Amazon EC2 instances, but it can become costly if not managed efficiently. To optimize EBS costs without sacrificing performance or reliability, several best practices can be implemented, such as selecting the appropriate EBS volume type for specific workloads, regularly rightsizing volumes using tools like Amazon CloudWatch and AWS Trusted Advisor, and implementing EBS snapshot lifecycle policies to manage storage costs. Additionally, using Amazon Data Lifecycle Manager (DLM) can automate the management of EBS snapshots, and optimizing performance involves ensuring applications use the correct I/O block size and considering EBS-optimized instances. It's also crucial to delete unused EBS volumes to prevent charges from orphaned volumes and to monitor costs with tools like AWS Cost Explorer, AWS Budgets, and AWS Trusted Advisor, using cost allocation tags for detailed insights.
