API for Elastic Load Balancing¶
|ABAP SDK "TLA"||
The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary
objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for Elastic Load Balancing is
This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.
To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the Elastic Load Balancing v2 module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.
About The Service¶
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.
Using the SDK¶
In your code, create a client using the SDK module for Elastic Load Balancing, which is created with
In this example we will assume you have configured
an SDK profile in transaction
DATA(go_session) = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ). DATA(go_el2) = /aws1/cl_el2_factory=>create( go_session ).
go_el2 is an instance of
and all of the operations
in the Elastic Load Balancing service are accessed by calling methods in
