Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
A load balancer distributes incoming traffic across targets, such as your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered targets and ensures that it routes traffic only to healthy targets. You configure your load balancer to accept incoming traffic by specifying one or more listeners, which are configured with a protocol and port number for connections from clients to the load balancer. You configure a target group with a protocol and port number for connections from the load balancer to the targets, and with health check settings to be used when checking the health status of the targets.
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, Gateway Load Balancers, and Classic Load Balancers. This reference covers the following load balancer types:
-
Application Load Balancer - Operates at the application layer (layer 7) and supports HTTP and HTTPS.
-
Network Load Balancer - Operates at the transport layer (layer 4) and supports TCP, TLS, and UDP.
-
Gateway Load Balancer - Operates at the network layer (layer 3).
For more information, see the Elastic Load Balancing User Guide.
All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat an operation, it succeeds.
Sending a Request Using ELBv2
var elbv2 = new AWS.ELBv2();
elbv2.createTargetGroup(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the ELBv2 object uses this specific API, you can
construct the object by passing the apiVersion
option to the constructor:
var elbv2 = new AWS.ELBv2({apiVersion: '2015-12-01'});
You can also set the API version globally in AWS.config.apiVersions
using
the elbv2 service identifier:
AWS.config.apiVersions = {
elbv2: '2015-12-01',
// other service API versions
};
var elbv2 = new AWS.ELBv2();

— (map
)Information for a path pattern condition. Specify only when
Field
ispath-pattern
.Values
— (Array<String>
)The path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig.

)The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig
— (map
)Information for a source IP condition. Specify only when
Field
issource-ip
.Values
— (Array<String>

)Information for a path pattern condition. Specify only when
Field
ispath-pattern
.Values
— (Array<String>
)The path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig.
HttpHeaderConfig
— (map
)Information for an HTTP header condition. Specify only when
Field
ishttp-header
.HttpHeaderName
— (String
)The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.

)The strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
QueryStringConfig
— (map
)Information for a query string condition. Specify only when
Field
isquery-string
.Values
— (Array<map>
)The key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in
Values
using a '\' character.If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.

Deleting a load balancer does not affect its registered targets. For example, your EC2 instances continue to run and are still registered to their target groups. If you no longer need these EC2 instances, you can stop or terminate them.

registerTargets(params = {}, callback) ⇒ AWS.Request
Registers the specified targets with the specified target group.
If the target is an EC2 instance, it must be in the running
state when you register it.
By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.
With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

)The host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
PathPatternConfig
— (map
)Information for a path pattern condition. Specify only when
Field
ispath-pattern

— (Array<String>
)The path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig.
HttpHeaderConfig
— (map
)Information for an HTTP header condition. Specify only when
Field
ishttp-header
.HttpHeaderName
— (String
)The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

— (Array<map>
)The key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in
Values
using a '\' character.If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Key
— (String
)The key. You can omit the key.
Value
— (String
)The value.
HttpRequestMethodConfig
— (map
)Information for an HTTP method condition. Specify only when
Field
ishttp-request-method
.Values
— (Array<String>
)The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig
— (map
)Information for a source IP condition. Specify only when
Field
issource-ip
.Values
— (Array<String>
)The source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig.
