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.
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.
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.
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.
