Which service should be used to collect votes for a popular television show with millions of submissions?

1. Amazon DynamoDB

2. Amazon Redshift

3. Amazon Kinesis

4. Amazon Simple Queue Service

The correct answer is: Amazon DynamoDB

When considering a service to collect votes for a popular television show that is expected to receive millions of submissions, utilizing Amazon DynamoDB is a robust choice because it is a fully managed NoSQL database service that offers high availability and scalability. DynamoDB provides the capability to automatically scale up to handle millions of requests per second, which accommodates the high volume of vote submissions during a show. It is designed to handle large amounts of unstructured data while ensuring low-latency performance. The use of key-value and document data structures allows for flexible and quick access to the data, essential for real-time voting scenarios. Additionally, DynamoDB offers features like automatic backups and secure data access controls, which are important for maintaining the integrity and security of voting data. The integration with AWS Lambda can automate processing and analysis of the vote data, enabling immediate responses to user submissions. In contrast, other options such as Amazon Redshift, primarily a data warehousing solution, may not be suitable for real-time voting due to its focus on complex query performance over large datasets rather than handling high-velocity transactional workloads. Amazon Kinesis, while suitable for real-time data stream processing, may add unnecessary complexity if the goal is merely to collect and store votes. Amazon Simple Queue
