Description
~~~~~~~~~~~
All load balancers utilize an algorithm that defines how traffic should
be directed between back end nodes. The default algorithm for newly
created load balancers is ROUND\_ROBIN, which can be overridden at
creation time or changed after the load balancer has been initially
provisioned.
The algorithm name is to be constant within a major revision of the load
balancing API, though new algorithms may be created with a unique
algorithm name within a given major revision of this API.
**Supported Algorithms**

| LEAST\_CONNECTIONS | The node with the lowest number of connections will receive requests. |

Description
~~~~~~~~~~~
Active health monitoring provides two types of health monitors, CONNECT or HTTP. The caller can configure one health monitor per load balancer.
The health monitor has a type attribute to signify which types it is. The required atrributes for each type is as follows:
**CONNECT Monitor**
The monitor connects to each node on its defined port to ensure that the node is listening properly.
The CONNECT monitor is the most basic type of health check and does not perform post-processing or protocol specific health checks. It includes several configurable properties:
- delay: This is the minimum time in seconds between regular calls to a monitor. The default is 30 seconds.
- timeout: Maximum number of seconds for a monitor to wait for a connection to be established to the node before it times out. The value cannot be greater than the delay value. The default is 30 seconds.
- attemptsBeforeDeactivation: Number of permissible monitor failures before removing a node from rotation. Must be a number between 1 and 10. The default is 2 attempts.
**HTTP Monitor**
The HTTP monitor is more intelligent than the CONNECT monitor. It is capable of processing an HTTP response to determine the condition of a node. It supports the same basic properties as the CONNECT monitor and includes the additional attribute of path that is used to evaluate the HTTP response to a monitor probe.
- path: The HTTP path used in the HTTP request by the monitor. This must be a string beginning with a / (forward slash). The monitor expects a response from the node with an HTTP status code of 200.
The default Health Monitor Configuration, when a load balancer is created is:
::
{
"type": "CONNECT",
"delay": "30",
"timeout": "30",
"attemptsBeforeDeactivation": "2"
}

| Resource | Operation | Method | Path |
+=================+==============================+==========+=================================+
| Load Balancer | Create a new load balancer | POST | {baseURI}/{ver}/loadbalancers |
+-----------------+------------------------------+----------+---------------------------------+
Description
~~~~~~~~~~~
This operation provisions a new load balancer based on the configuration
defined in the request object. Once the request is validated and
progress has started on the provisioning process, a response object will
be returned. The object will contain a unique identifier and status of
the request.
If the status returned is set to 'BUILD', then using the identifier of
the load balancer, the caller can check on the progress of the creation
operation by performing a GET on loadbalancers/{loadbalancerId}. When
the status of the load balancer returned changes to 'ACTIVE', then the
load balancer has been successfully provisioned and is now operational.
**Load Balancer Status Values**
+-------------------+----------------------------------------------------------------+
| Status Name | Description |
+===================+================================================================+
| BUILD | Load balancer is in a building state and not yet operational |
+-------------------+----------------------------------------------------------------+
| ACTIVE | Load balancer is in an operational state |
+-------------------+----------------------------------------------------------------+
| PENDING\_UPDATE | Load balancer is in the process of an update |
+-------------------+----------------------------------------------------------------+
| ERROR | Load balancer is in an error state and not operational |
+-------------------+----------------------------------------------------------------+
The caller of this operation must specify at least the following
attributes of the load balancer:
\*name
\*at least one node
If the request cannot be fulfilled due to insufficient or invalid data,
an HTTP 400 (Bad Request) error response will be returned with
information regarding the nature of the failure in the body of the
response. Failures in the validation process are non-recoverable and
require the caller to correct the cause of the failure and POST the
request again.
By default, the system will create a load balancer with protocol set to
HTTP, port set to 80 (or 443 if protocol is TCP), and assign a public
IPV4 address to the load balancer. The default algorithm used is set to
ROUND\_ROBIN.
A load balancer name has a max length that can be determined by querying
limits.
Users may configure all documented features of the load balancer at
creation time by simply providing the additional elements or attributes
in the request. This document provides an overview of all the features
the load balancing service supports.
If you have at least one load balancer, you may create subsequent load
balancers that share a single virtual IP by issuing a POST and supplying
a virtual IP ID instead of a type. Additionally, this feature is highly
desirable if you wish to load balance both an unsecured and secure
protocol using one IP address. For example, this method makes it
possible to use the same load balancing configuration to support an HTTP
and an TCP load balancer. Load balancers sharing a virtual IP must
utilize a unique port.
Request Data
~~~~~~~~~~~~
The caller is required to provide a request data with the POST which
includes the appropriate information to create a new load balancer.

This operation updates the attributes of the specified load balancer.
Upon successful validation of the request, the service will return a 202
(Accepted) response code. A caller should check that the load balancer
status is ACTIVE to confirm that the update has taken effect. If the
load balancer status is 'PENDING\_UPDATE' then the caller can poll the
load balancer with its ID (using a GET operation) to wait for the
changes to be applied and the load balancer to return to an ACTIVE
status.
This operation allows the caller to change one or more of the following
attributes:
\*name
\*algorithm
This operation does not return a response body.
.. note::
The load balancer ID, status, port and protocol are immutable
attributes and cannot be modified by the caller. Supplying an
unsupported attribute will result in a 400 (badRequest) fault.
Request Data
~~~~~~~~~~~~
Load balancer body with attributes to be updated.

| Node | Update a load balancer node | PUT | {baseURI}/{ver}/loadbalancers/{loadbalancerId}/nodes/{nodeId} |
+------------+-------------------------------+----------+-----------------------------------------------------------------+
Description
~~~~~~~~~~~
Every node in the load balancer is either enabled or disabled which
determines its role within the load balancer. When the node has
condition='ENABLED' the node is permitted to accept new connections. Its
status will eventually become 'ONLINE' to reflect this configuration.
When the node has condition='DISABLED' the node is not permitted to
accept any new connections. Existing connections to the node are
forcibly terminated. The nodes status changes to OFFLINE once the
configuration has been successfully applied.
The node IP and port are immutable attributes and cannot be modified
with a PUT request. Supplying an unsupported attribute will result in a
fault. A load balancer supports a maximum number of nodes. The
maximum number of nodes per load balancer is returned when querying the
limits of the load balancer service.
