An infrastructure is being hosted in AWS using the following resources:
a) A couple of EC2 Instances serving a Web-Based application
b) An Elastic Load Balancer in front of the EC2 Instances
c) An AWS RDS which has Multi-AZ enabled
Which of the following can be added to the setup to ensure scalability?
A. Add another ELB to the setup.
B. Add more EC2 Instances to the setup.
C. Enable Read Replicas for the AWS RDS.
D. Add an autoscaling group with sufficient instances to the setup
Explanation:
Answer – D
AWS Documentation mentions the following:
AWS Auto Scaling enables you to configure automatic scaling for the scalable AWS resources for your application in a matter of minutes. AWS Auto Scaling uses the Auto Scaling and Application Auto Scaling services to configure scaling policies for your scalable AWS resources.
- Option A is INCORRECT because adding another ELB to the setup will NOT bring in more scalability
- Option B is INCORRECT because just adding more EC2 instances to the setup will NOT bring in more scalability
- Option C is INCORRECT because just enabling read replicas for RDS to the setup will NOT bring in more scalability
