Load balancing is an important part of many applications and services, and Microsoft Power Automate desktop flows are no exception. Load balanced distribution of tasks across different resources is needed to ensure that no single resource gets overworked, leading to improved performance and efficiency. In this post, we’ll cover how to implement load balancing using machine groups and queues within Microsoft Power Automation.
Machine Groups in Power Automate
Machine groups provide a way of managing and distributing load between a group of machines running the Power Automate desktop application. They enable efficient distribution of desktop flows, facilitating load balancing, and ensuring optimal utilization of resources.
To create a machine group in Power Automate, visit the Machines tab under the Management section of the Admin Center. Click on ‘New’, fill the ‘Name’ field for your machine group, then click on the ‘Create’ button. Machine groups can be managed, edited or deleted using the respective options.
Queues in Power Automate
Queues are utilised in Power Automate to manage and distribute tasks or work items within a flow. Queues act as a buffer, storing the tasks that are yet to be processed. Work items get added to the end of the queue and are processed on a first in, first out basis. This enables better management of work items and distribution of tasks among machines in a machine group.
To create a queue in Power Automate, navigate to the ‘Data’ section in the left menu and select the ‘Tables’ option. Here, select ‘New table’ and fill in the necessary details. Once completed, tasks or work items can be added to this queue.
Load balancing using Machine Groups and Queues
Load balancing in Power Automate desktop flows is achieved by distributing work items in a queue across different machines in a machine group. This ensures that workload is shared among multiple machines, ensuring that no single machine is overworked.
In order to implement this, we first need to associate a flow to a machine group rather than a single machine. We do this by navigating to the Flows tab in the Power Automate portal, selecting a flow, and clicking on ‘Edit’. We then go to the ‘Run on’ section and change it from ‘This machine’ to ‘Machine group’. We select the appropriate machine group we created earlier.
Next, we modify the flow itself to retrieve items from a specific queue and process them. This can be done by using the ‘Get next item from a queue’ action in the flow and specifying the correct queue. This action will retrieve the next available item in the queue and mark it as ‘In Progress’. The task is then processed, and once it’s done, it can be marked as ‘Completed’ using the ‘Set item status as completed’ action.
An example for a simple automation, you have a queue that contains a list of urls to be scraped, and a flow to automate the scraping process. By associating this flow with a machine group, the URLs in the queue get distributed among the machines in the group. Every machine retrieves and processes a URL, one at a time, from the queue, ensuring that all URLs get processed and the workload is shared.
In conclusion, machine groups and queues in Microsoft Power Automate allow us to effectively implement load balancing, thereby managing and distributing tasks and workloads more efficiently across multiple machines. With these powerful features, you can make your workflows and processes more robust and efficient.

Interview Questions
What is the main purpose of load balancing in desktop flows?
The purpose of load balancing in desktop flows is to distribute workloads across multiple computing resources. This balances the demands by spreading tasks to prevent any single system from being overwhelmed.
What are machine groups in the context of Microsoft Power Automate?
Machine groups in Microsoft Power Automate are collections of devices that share specific attributes. Typically, these groups are used to apply policies or execute tasks across multiple systems that have common characteristics or roles.
How does the queue function within load balancing?
The queue function in load balancing facilitates the placement of tasks on a waitlist until the required resources are available. Only then will the task move from the queue to a machine, ensuring even distribution of tasks and preventing overuse of resources.
What is the benefit of using machine groups and queues in implementing load balancing?
Using machine groups and queues can maximize throughput, minimize response time, and avoid overloading any single resource, which improves the overall system’s efficiency and reliability.
Why is load balancing important for Robotic Process Automation (RPA) developers?
Load balancing is important for RPA developers as it ensures a smooth run time of automation and increases the efficiency of operations. It allows for tasks to be evenly distributed across bot resources, ensuring no single bot is overwhelmed.
How does Microsoft Power Automate helps in load balancing in RPA?
Microsoft Power Automate helps in load balancing by leveraging its Queue functionality. Tasks assigned to queues are distributed among available resources, resulting in more efficient operations and better use of available resources.
Can you adjust the load balance settings in Power Automate’s Admin Center?
Yes, in the Power Automate’s Admin Center, you can adjust and manage the load balance settings for your organization’s desktop flows, including creating and managing machine groups.
Why may RPA developers create multiple queues in Microsoft Power Automate?
RPA developers may create multiple queues to better control and manage their tasks based on priority, type of tasks, different operational hours, and high demand periods.
What tasks within Microsoft Power Automate can load balance across machine groups?
Tasks that can load balance across machine groups include assigning Azure AD roles, distributing desktop flows, creating and managing queues, and creating and editing records in Microsoft Dynamics 365.
What are queues in Microsoft Power Automate?
Queues in Microsoft Power Automate are ordered sets of tasks or items. Tasks are added to the queue and processed in the order they were received, implementing the FIFO (First In, First Out) principle. This helps in evenly distributing tasks and load balancing.
How does Power Automate handle unattended automation?
Unattended automation in Power Automate is handled through the use of “gateways”. These gateways provide the necessary connection between the local machine resources and Power Automate, allowing for tasks to be performed without explicit human activity.
What is the relationship between machine groups and queues in Power Automate?
In Power Automate, machine groups are associated with queues. Tasks are assigned to a queue, which will then distribute these tasks to the machines in the assigned machine group, providing balanced task distribution.
Can you run the same desktop flow on different machine groups at the same time?
Yes, the same desktop flow can execute on different machine groups at the same time, as long as there are available resources in those groups.
How does load balancing work in Power Automate?
Load balancing in Power Automate is managed automatedly by assigning tasks to different machine groups and queues. Tasks are distributed evenly across available resources to ensure optimal performance and avoid overuse of any single resource.
Is there a required prerequisite for implementing load balancing in Power Automate?
Before implementing load balancing in Power Automate, you must have administrative permissions and properly set-up machine groups and queue structures. Also, Gateway must be installed and correctly configured on each machine involved in the desktop flows.
