Communication Security for Software
Deployment
Deployment is the final stage of application development and it involves the transfer of application data to the target system. The AS Java uses a server side Deploy Controller to manage software deployment.
The Deploy Controller enables client applications to use APIs to enable deployment of software components on the AS Java server process. The client applications that use the Deploy Controller APIs use the P4 communication protocol for the connection to the AS Java.
The standard tools below use the Deploy Controller APIs and enable you to deploy software components on the AS Java
● SAP NetWeaver Developer Studio (NWDS)
During software deployment, the SAP NetWeaver Developer Studio connects to the Deploy Controller on the AS Java server using the Deploy Controller API. The connection between the NWDS and the target AS Java uses the P4 communication protocol.
● Shell Administration
For telnet deployment, you open a Telnet session to the AS Java and then use the Deploy Controller functions for software deployment. To secure the communication, we recommend that you can use a VPN.
For more
information about using these tools in your deployment scenario, see
Deployment: Putting It
All Together in the Development Manual. For an overview of the
communication flow, see the figure below.
