Basic Architectural Principles of Building in the AWS Cloud
Building applications in the AWS cloud requires understanding core architectural principles that ensure scalability, reliability, and cost-effectiveness. Here are the key principles:

1. Scalability
Horizontal Scaling (Scale-Out):

Add more instances to handle an increase in load.
Use services like EC2 Auto Scaling to automatically add or remove instances based on demand.
Vertical Scaling (Scale-Up):

Increase the size of an instance by adding more CPU, memory, etc.
Easier to implement but limited by the maximum instance size available.


2. Elasticity
Auto Scaling: Automatically scale your compute capacity up or down based on conditions you define.
Elastic Load Balancing (ELB): Distribute incoming traffic across multiple targets, such as EC2 instances, to ensure even load distribution and fault tolerance.

3. High Availability
Multi-AZ Deployments: Deploy applications across multiple Availability Zones (AZs) to ensure redundancy and failover.
Health Checks: Implement health checks and automatic failover mechanisms to detect and recover from failures.

4. Fault Tolerance
Redundancy: Duplicate critical components across different AZs or regions to prevent single points of failure.
Failover Strategies: Use services like Route 53 for DNS failover, and RDS Multi-AZ for database failover.
