b) Backing up data at regular intervals
c) Encrypting sensitive data in transit
d) Creating virtual private networks
Answer:
a) Automatically adjusting the number of EC2 instances based on demand
Explanation:
AWS Auto Scaling automatically adjusts the number of EC2 instances based on demand, ensuring that applications have the right amount of resources to maintain performance while minimizing costs. It scales out (adds instances) during peak demand and scales in (removes instances) when demand decreases.
This service helps optimize resource utilization, ensuring that applications can handle varying levels of traffic without over-provisioning or under-provisioning resources.
By using Auto Scaling, users can maintain application availability and cost-efficiency without manual intervention.
