Optimizing Unattended Infrastructure Using Machine Templates
- Don't know what machine objects are? Check out the article about machines.
- Learn a few basic notions about background versus foreground automation in this section on process types.
- See a couple of process compatibility considerations in this section on automation project target frameworks and operating systems.
The following table shows the UiPath® Robot version required to execute processes according to their target frameworks and OS compatibility considerations.
|
Operating system (target framework) |
Robot version |
|---|---|
|
Windows - Legacy (.NET Framework 4.6.1) |
Any |

Windows (.NET 5.0+) |
2021.10+ |

Cross-platform (.NET 5.0+) |
2021.10+ |

Invalid configuration. You need credentials to run foreground jobs. |
Your unattended workload has unique infrastructure needs that can change over time. You can maximize efficiency and minimize waste by restricting the machine template and the associated machine infrastructure to executing a particular type of process.
Let's say you've been using UiPath Studio for quite some time now, so inevitably you have gotten yourself a quite diverse collection of automations: background and foreground processes, some developed using .NET Framework 4.6.1, newer ones developed on .NET 5.0.
Your infrastructure consists of:
- one Windows desktop
- one high-density Windows Server
- three Linux machines
How would an efficient optimization strategy look like?

Why |
|---|---|---|---|
|
4 background processes |
Windows - Legacy (.NET Framework 4.6.1) |
We connect one Windows desktop using template A which we define as follows: Process type = Background only Process compatibility = Windows only Unattended Runtimes = 4 |
|
|
6 background processes |
Cross-platform (.NET 5.0 or higher) |
We connect 3 Linux machines using template B which we define as follows: Process type = Background only Process compatibility = Cross-platform only Unattended Runtimes = 2 |
|
|
10 foreground processes |
Windows (.NET 5.0 or higher) |
We connect the Windows server using template C which we define as follows: Process type = Foreground only Process compatibility = Windows only Unattended Runtimes = 10 |
|
- Allocate background processes execution to cheaper machines (such as Linux).
- Set Windows machines aside for foreground automation.
- Background processes developed using .NET Framework 4.6.1 require Windows. You can resort to Windows desktops for concurrent execution. You do not need a Windows server for background processes, nor a high-density environment, since background jobs can run concurrently under the same account.
- You need 2021.10+ robots to execute .NET. 5.0 or higher processes
Orchestrator does not allow starting jobs on invalid configurations. Trying to start a job in an invalid setup results in a descriptive error message providing you with details about how to fix your configuration.
Starting a job using dynamic allocation, i.e. no machine or account specified, with an incompatible folder setup results in an error. Make sure to correct the setup, otherwise, jobs stay pending indefinitely. For example, trying to run a .NET Framework 4.6.1 background job when there are only cross-platform templates in the folder does not work, as jobs stay pending until the configuration is fixed.
Find details about how to fix the configuration on the Job Details window.
- Foreground processes are developed on top of a UI and need a UI to get executed. Currently, UiPath foreground automation is only possible on Windows. For this reason, foreground automation on cross-platform-only machines is not a valid setup.
- Employing a Windows only template on a Linux machine is not a valid setup. Use Cross-platform only templates or unrestricted templates (All).
- Employing a Cross-platform only template on a machine with a UiPath Robot version smaller than 21.8+ is not a valid setup. Update the version or set the machine template to Windows only or All.
