Enterprise Application Architectures and Cloud Technologies

High availability is an important design characteristic. Which of the following is not related to high availability?

  • A Auto scaling supported by system
  • B Elastic Load Balance (ELB) for controlling traffic distribution
  • C Higher network bandwidth upper limit of a compute instance
  • D DR backup services for critical services
Explanation

Auto Scaling supports availability by maintaining healthy capacity, and Elastic Load Balancing routes traffic across healthy targets. Disaster-recovery backup services support restoration of critical services after failures. A higher maximum network bandwidth for one compute instance only increases potential throughput; it does not add redundancy or enable failover and therefore is not a high-availability feature.
