Architecture of Cluster Deployment

1 .. N R2Web Cluster Servers

1 .. N R2Web Session Pools

0 .. 1 R2Web Admin Console

R2Web Cluster

• This module is linked to the load balancer.

• The primary goal of this module is to efficiently direct requests from the browser to the session pool (application instance).

• This module ensures higher availability by allowing users to connect to the application instance from another cluster in case one cluster experiences downtime.

• R2Web Cluster follows the round-robin policy to select the connected session pool.

R2Web Session Pool

• This module manages the application instance.

• It oversees all R2 application instances initiated and supervised within this layer.

• This module is lightweight and can seamlessly connect to multiple clusters.

R2Web Admin Console

• The system will feature a single Admin Server to oversee operations.

• This module is designed to centrally handle application configurations for all connected clusters and session pools.

• Please note that the system permits only one Admin Server at any given time.
