Salient features of Citrix Gateway service
Some of the notable features of the Citrix Gateway service are as follows.
Multi-Layered resiliency approach by the Citrix Gateway service provides resiliency at every level. Within a particular Citrix Gateway service Point of Presence (POP), the micro services and tenants that form the service are deployed in a highly available form. The components are deployed in the N+1 model. In this model, all components are load balanced and can do a quick failover with standby, if there is some failure. In rare cases, when all the services of a particular component within a POP are down, the Citrix Gateway service marks itself as down. This enables the DNS server to redirect users to the next nearest POP, providing a POP level high availability.
Multiple instances of Citrix Gateway service are deployed in multiple geographic locations across the globe to handle its entire customer base. All the instances are constantly in sync with each other to provide one reliable service. From anywhere in the world, the user is never too far away from a Citrix Gateway service POP.
Citrix Gateway service is deployed globally and there is a need for a mechanism to choose the nearest POP. Optimal Gateway routing or proximity routing a DNS based service is used to return end users with the closest POP location when they query for the Citrix Gateway IP address. This DNS service uses the source IP address of the query as one of the metadata to return the closest Citrix Gateway service POP IP address.
A globally available service providing secure connectivity from users in any location to virtual apps and desktops.
