Elastic Load Balancing routes incoming traffic to multiple destinations such as Amazon EC2 instances and containers, IP addresses, Lambda function functions, virtual appliances, and containers. You can adjust the variable load of your application traffic within a single zone or across multiple Availability Zones. Elastic Load Balancing provides four types of load balancing that provide the required level of availability, automatic scaling, security, and security to make your applications fault-tolerant. Elastic Load Balancing, which is part of AWS, has native knowledge of fault limits such as AZ to keep your apps available in one region. It does not require Global Server Load Balancing. ELB is also fully managed, so you can concentrate on delivering your applications and not installing load balancers. Based on the usage of the underlying applications servers, capacity is automatically added or removed.
