How NITRO Works
Jun 03, 20 14
The NITRO infrastructure consists of a client application and the NITRO Web service running on a NetScaler appliance. The
communication between the client application and the NITRO web service is based on REST architecture using HTT P or
HTTPS.
Figure 1. NITRO execution flow
As shown in the above figure, a NITRO request is executed as follows:
1. The client application sends REST request message to the NITRO web service. When using the SDKs, an API call is
translated into the appropriate REST request message.
2. The web service processes the REST request message.
3. The NITRO web service returns the corresponding REST response message to the client application. When using the
SDKs, the REST response message is translated into the appropriate response for the API call.
To minimize traffic on the network, you retrieve the whole state of a resource from the server, make modifications to the
state of the resource locally, and then upload it back to the server in one network transaction.
Note: Local operations on a resource (changing its properties) do not affect its state on the server until the state of the
object is explicitly uploaded.
NIT RO APIs are synchronous in nature. This means that the client application waits for a response from the NITRO web
service before executing another NITRO API.
