Requesting a load balancer for a service
Load balancing servers in one or more server groups is done by selecting the Load Balance tab in
each server group configuration screen in infrastructure orchestration designer. Only one load
balancer can be specified per server group. The Load Balance tab allows the IO architect to specify
features of a load balancer that are desired in the service.
Optional tags can be specified to ensure that a particular load balancer is used. If tags are included,
infrastructure orchestration searches the inventory for a load balancer that meets the requirements
and has matching tags. Leaving the Tags field empty expands the selection of a load balancer for
the server group.
At least one network must be selected. All networks in the server group are displayed. Only a load
balancer that has access to the selected networks will be allocated.
The attributes of a load balancer that you can select for a server group are as follows:
High Availability
Requests a load balancer in a redundant configuration. This
means that there are two or more load balancers that back
up and monitor each other. If one load balancer fails,
another takes control so that users do not notice any
disruption of service.
SSL Capable Requests a load balancer on which an SSL certificate is
installed, which allows un-encrypted HTTP to be used over
the local network between the load balancer and the servers.
This improves performance on the servers.
Cookie Based Session Persistence Requests a load balancer with cookie based session
persistence. Persistence ensures that requests from a single
user are always distributed to the server from which they
started. Cookie based session persistence provides a
stateless solution for session persistence by storing all session
data in a cookie in the user's browser.
Source Address Session Persistence Requests a load balancer with source address session
persistence, or simple session persistence, which directs
session requests to the same server based on the source IP
address of a packet.
