Section 5: ELB & ASG - Elastic Load Balancing

What is the main purpose of High Availability in the Cloud

• Increase scalability

• Application thriving even in case of a disaster

• Access on computers and smartphones

• Handle greater loads by launching EC2 instances based on the demand

Which AWS offered Load Balancer should you use to handle hundreds of thousands of connections with low latency?

• Network Load Balancer (NLB)
• Elastic Load Balancer (ELB)

• Application Load Balancer (ALB)

Changing an EC2 Instance Type from a t3a.medium to a t3a.2xlarge is an example of?

• High Availability

• Vertical scaling
• Agility

• Horizontal scaling

What can you use to handle quickly and automatically the changing load on your websites and applications by adding compute resources?
