저는 dynamodb를 이용하여 간단한 시스템을 구축한 경험이 있었는데요.
DB 사용 비용이 상당히 비싼 것을 보고 좀 놀랐습니다.
제가 받은 청구내역은 아래 와 같이 약 5$정도 였는데요.
(실제 서비스 비용은 아니고 서비스전 개발중에 받은 청구서라 서비스시에 얼마가 나올지를 예상하기는 힘들었습니다.)

그런데, 아래 링크를 보면 제 경험에 비해 훨씬 저렴하게 비용이 산정되어있어서 놀랐는데요.
DB선정에 있어서 가격이 전부는 아니지만, 그래도 민감한 부분이기는 하기 때문에 DB를 어떻게 구성해서 사용해야 하는지는, 전문가(?) 면담이 필요한것 같습니다.

| About Product |
Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It enables you to run your database in the cloud without managing any database capacity.
With Aurora Serverless, you simply create a database endpoint, optionally specify the desired database capacity range, and connect your applications. You pay on a per-second basis for the database capacity you use when the database is active, and migrate between standard and serverless configurations with a few clicks in the Amazon RDS Management Console. |
Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications.
DynamoDB differs from other Amazon services by allowing developers to purchase a service based on throughput, rather than storage. If Auto Scaling is enabled, then the database will scale automatically. Additionally, administrators can request throughput changes and DynamoDB will spread the data and traffic over a number of servers using solid-state drives, allowing predictable performance. |

Onboarding
Good documentation that includes tutorials. Scalability On-demand auto scaling configuration, sharding. Regions US, Africa, Asia Pacific, China, South America, Middle East and Europe. The support varies across specific versions of each database engine, and across AWS Regions. Backups Aurora backs up your cluster volume automatically and retains restore data for the length of the backup retention period. You can specify a backup retention period, from 1 to 35 days, when you create or modify a DB cluster. Aurora backups are stored in Amazon S3. Security By default, Aurora Serverless v1 uses the Transport Layer Security/Secure Sockets Layer (TLS/SSL) protocol to encrypt communications between clients and your Aurora Serverless v1 DB cluster. It supports TLS/SSL versions 1.0, 1.1, and 1.2. |
Onboarding
Rich in documentation, with a great tutorial to start things off. Scalability Has automatic scaling as an option. Regions United States, Africa, Asia Pacific, Europe, Middle East. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. Backups Charged separatedly from the project. Has three different options: Continuous backups, on-demand, or restoring a table. Security AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. Includes data protection, identity and access management, infrastructure security, and more. |
| Technical Details |
|
Amazon DynamoDB is a NoSQL database that supports key-value and document data models. Developers can use DynamoDB to build modern, serverless applications that can start small and scale globally to support petabytes of data and tens of millions of read and write requests per second.
