Issue
my question is simple. Does it make sense to have an Amazon Elastic Load Balancer (ELB) with just one EC2 instance?
If I understood right, ELB will switch traffic between EC2 instances. However, I have just one EC2 instance. So, does it make sense?
On the other hand, I´m using Route 53 to route my domain requests example.com, and www.example.com to my ELB, and I don´t see how to redirect directly to my EC2 instance. So, do I need an ELB for routing purposes?
Solution
There is no need to use a Load Balancer if you are only running an single Amazon EC2 instance.
To point your domain name to an EC2 instance:
- In the EC2 Management Console, select Elastic IP
- Allocate New Address
- Associate the address with your EC2 instance
- Copy the Elastic IP address and use it in your Route 53 sub-domain
The Elastic IP address can be re-associated with a different EC2 instance later if desired.
Later, if you wish to balance between multiple EC2 instances:
- Create an Elastic Load Balancer
- Add your instance(s) to the Load Balancer
- Point your Route 53 sub-domain to the Load Balancer
