Introduction
Load Balancer is used to distributes the traffic and provide fault tolerance avaibility to your server.
- ELB can be public or private ( Depends on subnet you choose to launch it.
- It is highly recommended that you choose 2 subnets of different AZ to launch ELB.
- You can move Web-server to Private and keep only ELB in Public Subnet. Within a VPC all instance can talk to each other (Irrespective of Subnet).
- Traffic get distributed between 2 AZs in round-robin fashion.
- Within AZ, the instance with least number of open connection will get the next request.
- ELB should always be accessed using DNS and not IP.
- Define health check with care and look at the status of the instance (In service or not).
