AWS Elastic Beanstalk

Correct Answer: Use AWS Elastic Beanstalk to deploy the Node.js application, as it provides an easy-to-use platform for deploying and scaling web applications with automatic load balancing and auto-scaling capabilities.

AWS Elastic Beanstalk is the most suitable option for deploying a Node.js web application with minimal management overhead. It provides an easy-to-use platform that automatically handles the deployment, capacity provisioning, load balancing, and auto-scaling of the application. Elastic Beanstalk supports Node.js natively and abstracts away the underlying infrastructure management, allowing developers to focus on writing code. It ensures high availability by running the application on multiple EC2 instances across Availability Zones and scales the application based on demand, making it ideal for handling traffic spikes during peak hours. The other options, such as manually configuring EC2 instances or using container services like ECS, require more management effort and infrastructure setup compared to Elastic Beanstalk. While AWS Lambda is suitable for serverless architectures, it may not be the best fit for a complete web application deployment scenario.

Correct Answer: Rolling updates for zero-downtime deployments

AWS Elastic Beanstalk provides deployment options that support rolling updates, which allow for zero-downtime deployments. This means that during the deployment process, the new version of the application is gradually rolled out while the old version continues to serve requests, ensuring uninterrupted service. The other options mentioned, such as automatically creating a multi-region infrastructure, seamless integration with AWS Lambda for serverless deployments, or built-in support for containerized workloads using ECS or EKS, are not specific features of Elastic Beanstalk's deployment options.

Correct Answer: A platform for deploying and managing applications in the AWS Cloud

AWS Elastic Beanstalk is a platform that simplifies deploying and managing applications in the AWS Cloud. It automatically handles the deployment details of capacity provisioning, load balancing, auto-scaling, and application health monitoring. The other options describe different AWS services: Amazon RDS for managed relational databases, Amazon Simple Email Service (SES) for sending emails, and Amazon S3 for object storage.
