AWS-3 Tier Application Architecture

The AWS 3-Tier Application Architecture Template provides you with a pre-built framework to structure a web application in a tidy and systematic manner. It uses a pattern used by many successful applications across the globe: 

• The Web Layer does everything the users interact with. 

• The Application Layer is the logic or "brain" of your application. 

• The Database Layer securely stores your data. 

Each layer has a different role, but this keeps things easy, secure, and simpler to manage. The template uses AWS services such as Route 53, CloudFront, EC2, Auto Scaling, and RDS to easily and reliably set this up. 

Why this template is a game changer ?

If you attempt to create a web application from scratch, you need to choose how to setup servers, manage user traffic, store information, and keep things working even in the event that something breaks. That is a time-consuming process, and a single error may impact your system. 

This template eliminates that issue. It provides you with: 

• A ready-made map of the way everything fits together. 

• Inherent scalability, so your application can expand as users increase. 

• High availability, so your application remains up and running even when something fails. 

• Security, with AWS features such as IAM roles and security groups. 

• Simplistic means to view and modify your setup with Cloudairy. 

You don't need to create everything from scratch using this template. You have a solid foundation to work from and the ability to make changes according to your requirements. 

Who needs this template, and when to use it? 

This template is great for: 

• Developers build new web apps. 

• Startups launching their products. 

• Teams moving from on-premises to cloud. 

• Businesses that want a reliable and flexible cloud system. 

It’s most useful when you’re: 

• Starting a new project. 

• Rebuilding an old application. 

• Planning to grow your app. 

• Wanting better speed, performance, and reliability. 

If you don't know how to design your app on AWS or don't have the time to learn it from scratch without wasting weeks, this template is for you. 

What are the main components of the template? 

This structure contains the essential building blocks you require for a solid application: 

• Route 53 (DNS): Routes user traffic to your site or app. 

• CloudFront (CDN): Speed up content delivery by serving it from local servers. 

• VPC (Virtual Private Cloud): Maintains your app's network private and managed. 

• Web Subnet: Hosts web servers in multiple zones for improved availability. 

• Load Balancer: Distributes user traffic among servers to prevent overload. 

• Auto Scaling: Adds or takes away servers based on traffic requirements. 

• App Subnet: Hosts the core logic of your app in the background. 

• RDS (Primary Database): Stores user and app data securely. 

• RDS (Multi-AZ): Maintains a duplicate database in a different zone in case of failure. 

• S3 Bucket: Holds static assets such as images, videos, or backups. 

• Security Groups: Manages who can connect to your servers. 

• IAM Roles: Provides services with the appropriate access without over-permission. 

• Monitoring Tools: Monitors performance, usage, and system health. 

These parts are intended to complement each other. The web layer links users, the app layer processes things, and the database layer holds information all while ensuring everything works smoothly.
