Understanding the AWS Nuanced Cost Structure

In the first chapter, we will highlight the fundamentals of AWS cost structure before proceeding with optimization strategies.  It is paramount to understand the cost structure and the essential components that contribute to determining AWS’s pricing policy.

AWS mainly operates on a pay-as-you-go model to offer extensive service ranges charged on a usage basis. This is dissimilar to the traditional on-premise model, where you can control the price. The core factors that largely determine the AWS pricing model are

1. Compute Costs
   AWS charges to compute resources based on usage duration, provisioned capacity, and instance type. For instance, EC2 is billed per hour, minute, or second, depending on its usage, while AWS Lambda functions are priced based on the number of invocations and execution time.
2. Storage Costs  
   AWS charges for storing your sensitive data information on its cloud database with options like S3, Glacier, and EBS. Each of these storage options has separate pricing models and the vital cost-determining factors include storage volume, data transfer, and retrieval frequency. For example, S3 bills you for storage volumes and data transfer, while Glacier provides lower-cost archival storage with longer retrieval times.
3. Data Transfer Costs 
   AWS also charges its customers for transmitting data between different regions and services. The pricing depends on transfer speeds, data volumes, and destination regions. Intra-region transmissions are often free or cost-effective than inter-region transfers. For example,  you don’t have to pay anything when transferring EC2 data within the same region, but data transferred out of AWS will be chargeable.
4. Additional Services Costs 
   Amazon Web Services offers a host of services besides commuting, data transfer, and storage facilities. The pricing model of all these services is based on its core features, usage, and resource consumption. For example, the cost of Amazon RDS is usually determined by database instance hours and storage capacity.  On the contrary, if you are using Amazon Redshift, you have to pay the bill for compute node hours and data transfer.

Therefore, you must understand the pricing model of these service-specific structures to calculate cost optimization in AWS.
