Green Screens - Network Infrastructure

Basic network infrastructure showing how local and remote clients connects to IBM I platform from Android based application or web browser through Green Screens Service providing high level of security features while isolating IBM I from direct access.

Green Screens Server can be single instance or multiple instances and load balancer to distribute large number of workstations. Ideal for redundancy or resource distribution to improve performance. Advanced security protocol features are used including custom encryption, OTP access control, mobile UUID access control, URL link sharing prevention, IP based session access control and many more. All terminal access is through standard web ports 80 or preferably 443 (SSL) which works out of the box through all networks without need for special network infrastructure configuration.

Intranet access (local network)

Intranet infrastructure shows how clients connect from local network through Green Screens Service to the IBM I platform.

All clients connects through browser or mobile app to Green Screens Service instead to IBM I server.
Printing is operating through web browser where spool files are converted into PDF and available for printing to any modern printer without requirements for PCL support.
Green Screens Service can be installed on MS Windows, Linux, AIX, IBM I or any other OS supporting Java.

Internet access

Internet infrastructure shows how remote clients connect from remote locations through Green Screens Service to IBM I platform.

IBM I platform is isolated from direct Internet access protecting resource from external attacks as DDoS.
Green Screen Services can run in multiple separate processes, one for Intranet, another one for Internet.
Shooting down Internet service to prevent further damage will not terminate local connections in a case if intrusion or DDoS attack.
Printing spool files works the same way as in local network without any special network requirements or setups.

Cloud feature

Cloud feature supports installation of Green Screens Service in cloud environments.

MS Windows, Linux and Docker installation types are available.
It is ideal for cloud providers and companies providing IBM I outsourcing.
All security features are available as in all other types of installations giving high level resource protection and IBM I isolation.
Additionally, IBM I machines might be located out of the cloud environment and accessed through VPN networks.

Tunnel feature

Tunnel feature supports Green Screens Service installation inside cloud environments securely accessing IBM i servers inside company internal network without IBM server being exposed online.

Install single exe program inside local network, set IP routes, access key, and allow single port on company firewall.

MS Windows, Linux and Docker installation types are available.
Ideal for companies without IBM I outsourcing and without GS installation.
All security features are available as in all other types of installations giving high level resource protection and IBM I isolation.
IBM I machines are located in.house and accessed through VPN tunnel.
