AWS | Amazon Web Servicesv1.0.2

A tech startup needs to deploy a web application with minimal upfront cost and scalability for growth. The skill guides selecting a single EC2 instance and RDS database, setting up cost alerts, and implementing security defaults like VPC isolation and least privilege IAM.

An enterprise is migrating legacy on-premises infrastructure to AWS, requiring architecture decisions, cost optimization, and security hardening. The skill helps design multi-AZ deployments with ALB and ASG, generate Terraform for reproducibility, and avoid cost traps like idle load balancers.

An e-commerce business experiences traffic spikes during sales events and needs to scale infrastructure efficiently. The skill recommends ECS/EKS with Aurora and ElastiCache, implements monitoring with CloudWatch alarms, and optimizes performance using RDS Proxy to handle connection limits.

A research organization requires a big data pipeline for processing large datasets with cost-effective storage and compute. The skill advises using S3 for storage, Lambda for serverless processing, and selecting EBS volume types like st1 for throughput, while setting up lifecycle policies to manage snapshots.

A SaaS provider needs to architect a multi-tenant application with isolated resources and cost allocation. The skill assists in designing VPC endpoints to avoid NAT Gateway costs, tagging strategies for billing, and security hardening with encryption and restricted outbound rules.

This model involves recurring revenue from users accessing cloud-hosted software. The skill optimizes costs with serverless components like Lambda and API Gateway to minimize idle expenses, while ensuring scalability and security for multi-tenant environments.

Revenue is generated through transaction fees or product sales on an online platform. The skill helps deploy scalable infrastructure with ALB and ASG to handle variable traffic, implement caching with ElastiCache for performance, and monitor costs to avoid surprises during peak seasons.

Businesses offer AWS infrastructure management and optimization services to clients. The skill provides tools for architecture guidance, cost tracking, and security audits, enabling consultants to deliver value by avoiding common traps and ensuring efficient deployments.
