Amazon DynamoDB

Here is a list of key items for optimizing costs in Amazon DynamoDB. If you are using or planning to use this service, you absolutely need to understand these points. I would like to highlight special attention to items 1, 2, and 3.

In Item 1, “Use Gateway VPC Endpoint,” although it is simple, it is still often overlooked, particularly in large enterprises, where it is treated as an optional item and delayed. This can lead to unnecessary financial waste, even though the Gateway Endpoint can be easily configured.

Item 2, “Avoid Scan Operation,” which I refer to as “the priciest AWS blunder of them all.” If you’re a developer, this is a critical concept you need to grasp, as using scan operations can lead to significant and unnecessary costs if not handled correctly.

Similarly, Item 3, “Prefer Provisioned Capacity,” is often neglected just like Item 1.
