AWS 3 Tier Architecture with Disaster Recovery | AWS 3 tier architecture Interview Questions

Описание: In this video, we explain a real DevOps interview question about AWS architecture.

We will understand how to design a highly available and fault tolerant AWS infrastructure using multiple regions.

This architecture includes several important AWS services such as:

• Amazon Route 53
• AWS WAF
• Amazon CloudFront
• Elastic Load Balancer
• Auto Scaling Groups
• Amazon EC2
• Amazon RDS
• NAT Gateway
• Bastion Host
• AWS Backup

The architecture demonstrates how modern applications achieve high availability, scalability, and disaster recovery using AWS cloud services.

We also explain the request flow from the client to the database layer and how traffic is distributed across different availability zones.

This type of architecture is commonly asked in DevOps, Cloud Engineer, and AWS interviews.
