SimpleDB features and specs

• Scalability
  SimpleDB automatically manages server infrastructure on behalf of users, allowing it to scale in response to application demand without manual intervention.
• Ease of Use
  It is designed to be simple, with a straightforward API that makes it easy to get started without needing to manage the complexities of traditional database systems.
• Flexible Data Model
  The schema-less nature of SimpleDB allows users to store structured data without predefining the data types, making it adaptable to changes in data format or structure.
• Indexing and Querying
  SimpleDB provides automatic indexing of all attributes, which facilitates quick querying and retrieval of data without requiring users to manage indices.
• Integration with AWS Services
  Seamless integration with other AWS services like S3 and EC2, allowing users to build comprehensive cloud solutions.

Possible disadvantages of SimpleDB

• Limited Query Functionality
  SimpleDB's querying capabilities are more limited compared to relational databases; it does not support complex queries or joins.
• Storage and Throughput Limitations
  There are limitations on storage size per domain and concurrent read/write throughput, which could be restrictive for large-scale applications.
• Consistency Model
  SimpleDB trades off strong consistency for high availability, which means applications must be designed to handle eventual consistency.
• Cost
  While SimpleDB can be cost-effective for small applications, costs can accumulate quickly with large-scale data operations due to its pricing model based on data usage.
• Obsolescence
  With the advancement and growing use of more robust AWS databases like DynamoDB, SimpleDB has become less appealing and might not receive the same level of support or updates.
