A company is developing an application hosted on Amazon EC2. The application requires 24/7 availability and a scalable, highly available architecture. Which two design guidelines should be applied?
A
Utilize EC2 Spot Instances for cost savings, understanding potential interruptions due to market pricing.
B
Implement Multi-AZ deployments to ensure high availability and automatic failover across different availability zones.
C
Employ Auto Scaling groups to dynamically adjust EC2 instances in response to application demand, supporting scalability and high availability.
D
Adopt AWS Backup for data protection and disaster recovery, recognizing its role in data safety rather than directly in high availability.
E
Consider EC2 Reserved Instances for cost-effectiveness, noting their irrelevance to the architecture's high availability and scalability.
