What is a a Dyalog Run-Time Licence and When Do You Need One?
XXX Need some explanation of what a Run-Time Licence actually is.
In addition to a current Developer Licence, a Run-Time Licence is necessary if:
- Dyalog is used to implement multi-user applications (multi-user applications are defined as applications where the same data is shared by or exchanged between two or more users).
- Dyalog is used as a platform for applications that are distributed outside the organisation which holds the Commercial or Basic Licence – whether or not the developer charges a fee for the application and irrespective of whether the application is single or multi‑user.
Run-Time licences can be either usage-based or royalty-based
In the absence of the purchase of a suitable Usage-Based Run-Time Licence, the Royalty-Based Run-Time Licence will be applied as the default licence.
Usage-Based Run-Time Licences
For sharing applications
The Usage-Based Run-Time Licence charges an annual fee that depends on how it is deployed. Different metrics of use can be applied; two examples are shown below. If neither of these fit with the way that your business is organised, please contact us and we can work with you to identify a metric that can be used to determine a fair price structure for the required Run-Time Licences.
Annual Fee
The Usage-Based Run-Time Licence charges an annual fee that depends on how it is deployed.
Usage Metrics
Different usage metrics can be applied to determine how the annual fee is calculated.
Scalable Pricing
Licence costs scale with actual use, providing a fair and predictable pricing structure.
Custom Pricing
If our standard metrics don’t apply, Dyalog Ltd can help define a suitable pricing model.
Usage-Based Run-Time Licence Examples
Usage Example: User-Based Run-Time Licences
When several users use one or more applications on a shared server, a Run-Time Licence is required. Examples of this are applications that are running under Citrix or similar platforms, Web Servers, servers using Distributed COM or other transactional platforms. The minimum server configuration is for 20 users.
All-Inclusive Coverage
Run-Time Licences are inclusive of all necessary Licences. If, for example, an application allows 20 desktop users to share data on the server, a Run-Time Licence for 20 users includes all relevant fees for desktop users and server.
All-Inclusive Coverage
For Facility Management Applications, where an organisation is running a service on behalf of several client organisations, appropriate Run-Time Licences are required for each distinct customer organisation.
These Run-Time Licences are priced on a per user basis. If it is not possible to determine the number of users (for example, an application within in a container or virtual machine) an alternative Use-Based Run-Time Licence or Royalty-Based Run-Time Licence could be used.
When do I need a User-Based Run-time Licence?
A User-Based Run-time Licence is required when several users use one or more applications on a shared server. This includes applications running under Citrix or similar platforms, web servers, or servers using Distributed COM or other transactional platforms. The minimum configuration is for 20 users.
What does the licence include?
Everything you need: both server and desktop user components are covered in one licence.
How does pricing work?
Per user. If you can’t count individual users (e.g., containerised apps), consider a Royalty-Based licence instead.
What about multi-client scenarios?
Facility managers serving multiple client organisations need a separate licence for each distinct customer organisation.
 User-Based Run-Time Licences | Annual Cost |
|---|---|
Up to 20 users | £1,125 |
Up to 50 users | £2,250 |
Up to 100 users | £3,750 |
Up to 250 users | £6,000 |
Up to 500 users | £9,750 |
500 or more users | Contact Sales |
When is a Cloud-Based Run-time Licence required?
When your application runs in the cloud and serves multiple users or automates workflows using cloud resources.
What types of cloud use are covered?
Services that provide fractional access throughout the year (e.g., applications using Jarvis or MiServer), and cloud resources used for parallel computation, workflow automation, or continuous integration tasks that don’t directly serve end users.
How is a Cloud-Based Run-time Licence priced?
You pay Dyalog Ltd the same amount as you pay your cloud provider for the computing resources used to run Dyalog.
What if my cloud usage costs aren’t clear?
Contact us to agree on a suitable pricing metric that works for your deployment.
Usage Example: Cloud-Based Run-Time Licences
When several users use one or more applications running in the cloud, a Run-Time Licence is required.
Examples include:
- a service where an application, that runs in the cloud, provides services available to users for a fraction of the working year (for example, applications running Jarvis or MiServer).
- use of internal or external cloud resources to accelerate or automate the execution of a workflow on behalf of a controlling process, but without providing a service that other users could connect to or receive data from. Examples include the use of isolate servers running in the cloud for parallel computation, or the execution of continuous integration tasks on the cloud.
For cloud-based deployment of applications, our default pricing is that you pay Dyalog Ltd the same amount as you pay your cloud provider for the computing resources to run Dyalog in the cloud. If those costs are not easily identifiable – please contact us to discuss pricing.
