Complete Guide: Deploying a Web Application on AWS

A detailed guide to the different options for deploying web applications on AWS, with their advantages and specific use cases.

Introduction

AWS offers several options for deploying web applications, each suited to specific needs. Here is a comparative analysis of the main solutions.

Deployment Options

1. Elastic Beanstalk

• Type: PaaS (Platform as a Service)
• Use case: Fast deployment of web applications
• Advantages:
  • Simplified deployment
  • Automatic infrastructure management
  • Support for multiple languages
• Disadvantages:
  • Less flexible than ECS/EKS
  • Limited customization

2. Amazon ECS (Elastic Container Service)

• Type: Containers (Docker)
• Use case: Containerized applications
• Advantages:
  • High scalability
  • Integration with ECR
  • Monitoring via CloudWatch
• Disadvantages:
  • Complex initial setup
  • Requires Docker knowledge

3. AWS Fargate

• Type: Serverless containers
• Use case: Microservices
• Advantages:
  • No infrastructure management
  • Automatic scaling
  • Container isolation
• Disadvantages:
  • Potentially higher cost
  • Less control over the infrastructure

4. Amazon EKS (Elastic Kubernetes Service)

• Type: Kubernetes orchestration
• Use case: Complex applications
• Advantages:
  • Very high scalability
  • Application portability
  • Rich Kubernetes ecosystem
• Disadvantages:
  • Increased complexity
  • Higher cost
  • Requires Kubernetes skills

5. Amazon EC2

• Type: Virtual machine
• Use case: Full control
• Advantages:
  • Complete control
  • Maximum flexibility
  • Total customization
• Disadvantages:
  • Manual administration
  • Manual scaling
  • Maintenance required

6. AWS Lambda

• Type: Serverless
• Use case: Serverless backend
• Advantages:
  • Pay-per-use billing
  • Automatic scaling
  • No maintenance
• Disadvantages:
  • Execution limits
  • Cold starts
  • Not suited to every use case

7. Amazon S3 + CloudFront

• Type: Static hosting + CDN
• Use case: Static websites
• Advantages:
  • Optimal performance
  • Low cost
  • Built-in security
• Disadvantages:
  • Limited to static applications
  • No built-in backend

8. API Gateway + Lambda

• Type: Serverless API backend
• Use case: REST/HTTP APIs
• Advantages:
  • Serverless architecture
  • Automatic scaling
  • Built-in security
• Disadvantages:
  • Potential latency
  • Execution limits
  • Variable cost
