High availability
Suggested answer: D

Explanation:

Understanding High Availability: High availability (HA) refers to systems that are durable and likely to operate continuously without failure for a long time. HA ensures that an architecture can withstand failures with minimal downtime.

Importance of High Availability:

Redundancy: Systems are designed with redundancy to prevent single points of failure.

Fault Tolerance: Ensures that failures do not result in significant downtime, maintaining service continuity.

Automated Recovery: Utilizes automated recovery mechanisms to quickly restore services in the event of a failure.

AWS Services for High Availability:

Multi-AZ Deployments: Services like RDS, DynamoDB, and others support Multi-AZ deployments for fault tolerance.

Elastic Load Balancing: Distributes traffic across multiple instances or availability zones to ensure no single point of failure.

Auto Scaling: Automatically adjusts the number of instances based on demand, ensuring availability even during traffic spikes.
