PRIMECLUSTER provides architectural patterns for ensuring the connectivity between a terminal directly operated by a user and the management view client.
For smooth designing of a cluster system, choose the appropriate one from these architectural patterns.
The following are the architectural patterns for the connectivity with the Web-Based Admin View and the appropriate scenarios for each pattern.
Architectural pattern | Appropriate scenario | Note |
|---|---|---|
Ensuring connectivity with a server for a client | Pattern using a server for a client | On NIFCLOUD, the server for the management view client that is connected with the private LAN for the administrative LAN must be deployed. |
Ensuring connectivity using a VPN connection | Pattern using a VPN connection | An additional device is required for a VPN connection. |
In the pattern using a server for a client, to ensure the connectivity between a terminal directly operated by a user (remote control terminal of the management view client) and the management view client, prepare a server for the management view client deployed on NIFCLOUD.
The system component for a VPN connection is not required and the configuration may be simple.
When selecting this architectural pattern, a user connects to the management view client via a remote desktop connection.
For a remote desktop connection from the Internet, it is necessary to connect a router to the Internet and use the DNAT function for a connection via the router, or to build the server connected to the Internet as a reverse proxy server on NIFCLOUD for a connection via the reverse proxy server.
Also, to allow the access to the server from the Internet, the firewall rule must be firmly established.
Figure 8.5 Ensuring connectivity with a server for a client
In the pattern using a VPN connection, to ensure the connectivity between the management view client and the operational server, or the standby server, a VPN connection is used.
No management view client is required on NIFCLOUD. It is also possible to securely connect to an environment on NIFCLOUD.
When selecting this architectural pattern, a terminal directly operated by a user is the management view client.
To provide a VPN connection, the VPN must be set or a device is required in the network where the terminal directly operated by a user is deployed.
