The primary purpose of load balancers in cloud networking is to distribute incoming network traffic
across multiple servers, thereby:
Ensuring Availability: By balancing traffic, load balancers prevent server overload and ensure high
availability.
Performance Optimization: Evenly distributing traffic reduces response time and improves user
experience.
Fault Tolerance: If one server fails, the load balancer redirects traffic to healthy servers, maintaining
service continuity.
Scalability: Automatically adjusts to traffic changes by adding or removing servers as needed.
Use Cases: Commonly used for web applications, databases, and microservices in cloud
environments.
Other options analysis:
B . Optimizing database queries: Managed at the database level, not by load balancers.
C . Monitoring network traffic: Load balancers do not primarily monitor but distribute traffic.
D . Load testing applications: Load balancers do not perform testing; they manage live traffic.
