Load Balancing with Parallels RAS

Load balancing plays a critical role in application and desktop delivery by spreading workload between servers and providing reliable access to published resources. Parallels Remote Application Server (RAS) offers the ability to load balance RDSH servers as well as its internal components, such as RAS Gateway. Load balance your entire infrastructure without complex network configurations or expensive add-ons.

Server Load Balancing 

Server load balancing is easy to use and available out of the box from the first installation. It distributes user access among healthy servers hosting the same application, which improves response time, guarantees full optimization of the computing resources, and prevents any single point of failure. Read more.  

Resource-Based and Round-Robin 

Parallels RAS allows resource-based or round-robin load balancing. Round-robin is a simple rotational-based mechanism that load balances the connections. The first request grants access to the first available server address, the second to the second server address, and so on.  

Parallels RAS resource-based load balancing dynamically distributes the traffic between servers based on counters, such as number of existing user sessions, memory, and CPU utilization. In addition, it reconnects the disconnected servers by default, so users don’t lose any work or data. 

Auto-Scaling with RDSH Template 

Parallels RAS RDSH template allows the dynamic provisioning of RDS servers, automating the scaling of RDSH. It works by creating or removing virtual desktop infrastructure (VDI) clones of the specified RDSH server when requested by the template rules. Specific template rules can be set based on a workload threshold scenario. For instance, administrators can define how many RDS servers they need to manage a 20% increase in traffic. 

Parallels RAS RDSH template enables organizations to dynamically scale up or down the number of RDS hosts by creating, removing, or employing RDSH servers on demand.  

By creating and deploying RSHD on the fly, IT administrators can save a great deal of time and reduce their workload concern about possible excess traffic.
