This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, must not begin or end with a hyphen, and must not begin with "internal-".

If you don't specify a name, AWS CloudFormation generates a unique physical ID for the load balancer. If you specify a name, you cannot perform updates that require replacement of this resource, but you can perform other updates. To replace the resource, specify a new name.

setName

@Stability(Stable)
public void setName(@Nullable

This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, must not begin or end with a hyphen, and must not begin with "internal-".

If you don't specify a name, AWS CloudFormation generates a unique physical ID for the load balancer. If you specify a name, you cannot perform updates that require replacement of this resource, but you can perform other updates. To replace the resource, specify a new name.

getScheme

@Stability(Stable)
@Nullable
public String getScheme()

The nodes of an Internet-facing load balancer have public IP addresses.

The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

The default is an Internet-facing load balancer.

You cannot specify a scheme for a Gateway Load Balancer.

setScheme

@Stability(Stable)
public void setScheme(@Nullable
 String value)

The nodes of an Internet-facing load balancer have public IP addresses.

The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

The default is an Internet-facing load balancer.

You cannot specify a scheme for a Gateway Load Balancer.
