You have been asked to design a high-availability architecture for a web application that needs to handle fluctuating levels of traffic. Which combination of services would best meet this requirement?
This setup provides a high-availability architecture by distributing traffic across multiple Availability Zones using an Application Load Balancer in combination with EC2 Auto Scaling. Auto Scaling dynamically adjusts the number of EC2 instances based on traffic demand, while the Load Balancer ensures that incoming requests are balanced across zones. This configuration is both resilient and well-suited for handling fluctuating traffic loads.
Which AWS service would you use to manage a relational database that automatically takes care of backups, patching, and scaling?
Amazon RDS (Relational Database Service) is specifically designed to manage relational databases on AWS. It handles routine database tasks like backups, software patching, monitoring, and scaling, freeing up users to focus on application development rather than database maintenance.
You are setting up a multi-tier architecture on AWS. Which service should you use to decouple the application layer from the database layer?
Amazon SQS (Simple Queue Service) is a fully managed message queuing service that allows you to decouple application components. In a multi-tier architecture, SQS can be used between the application and database layers to manage and balance requests, ensuring smooth and resilient communication between services.
Which AWS service allows you to deploy applications in Docker containers and automatically manage the underlying infrastructure?
Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that supports Docker containers. ECS automates the deployment, management, and scaling of containerized applications, making it a great choice for microservices or applications requiring Docker-based environments.
You need to ensure that users across the globe can access your application with low latency. Which AWS service would you use to distribute content closer to users?
Amazon CloudFront is a global content delivery network (CDN) service that caches and delivers content from edge locations worldwide. It minimizes latency by serving content from servers located closer to users, enhancing performance and providing a better user experience, especially for global applications.
