Which of the following statements are TRUE when it comes to elasticity. Choose 2 answers from the options given below.
A
Diverting traffic to instances based on the demand
B
Diverting traffic to instances with the least load
C
Diverting traffic across multiple regions
D
Diverting traffic to instances with higher capacity
Explanation:
Elasticity in cloud computing refers to the ability to automatically scale resources up or down based on demand. The correct answers are:
A. Diverting traffic to instances based on the demand: This is a key aspect of elasticity where traffic is automatically routed to instances that can handle the current demand, allowing for efficient resource utilization.
B. Diverting traffic to instances with the least load: This is also part of elasticity as it helps distribute traffic evenly across available resources, preventing overloading of any single instance and maintaining performance.
Why the other options are incorrect:
C. Diverting traffic across multiple regions: While this relates to high availability and disaster recovery, it's not specifically about elasticity which focuses on scaling within a region or availability zone.
D. Diverting traffic to instances with higher capacity: This is more about load balancing based on instance capacity rather than the dynamic scaling aspect of elasticity.
