Cloud Computing Fundamentals

A team is developing a stateless web application. To manage traffic efficiently and preserve continuous service, which approach distributes load among multiple independent servers?

  • A Scale vertically by upgrading to a larger single server instance.
  • B Use a content delivery network (CDN) to serve static assets efficiently.
  • C Shard the database to split traffic across data storage nodes.
  • D Scale horizontally with multiple servers behind a load balancer.
Explanation

Horizontal scaling places multiple interchangeable application servers behind a load balancer, which distributes incoming traffic across instances and maintains service when an individual server becomes unavailable.
