Basic web Application.

Here’s a basic web application.

1. Load Balancer

Purpose

• Distributes incoming traffic across multiple frontend or backend servers.
• Prevents overload on a single server.
• Improves availability and fault tolerance.

Scaling Strategy

• Horizontal scaling Multiple load balancers. Vertical scalling would be good for capacity boosts but horizontal scaling provides redundancy.
• High availability is essential.

Redundancy

• Deploy across multiple availability zones/regions.

2. Web Servers

Purpose

• Serve the user interface.
• Handle client-side requests and static assets.

Scaling Strategy

• Horizontal scaling Add more frontend instances for the load balancer to direct traffic to as traffic grows.

High Availability is essential.

• Yes.
• Multiple frontend instances behind a load balancer.

3. Database Layer

Purpose

• Store application data.
• Support transactions and queries.

Scaling Strategy

• Vertical scaling More CPU/RAM/storage for performance.

High Availability

• Very important.

4. Storage Solutions

Purpose

• Store files, backups, logs, images, videos, and static content.

Scaling Strategy

• Horizontal scaling.

High Availability

• Required for production.
• Replicate in availability regions or zones.
