Hi,
How many API calls can be handle by Outsystems server in Parnell. In my project there is enterprise edition of Outsystems and now client want to know the exact numbers of end users who can access the same screen or Rest API in Outsystems. Or better if can little overview how integration calls (rest api) get manage in Outsystems.
Thanks in advance.
Technically there isn't a limit. The .NET version of Outsystems is based on IIS front end with SQL backend and is capable of handling any level of users and concurrent connections that you would expect with that setup. For example if you have a very high level of users you can stand up multiple front end servers and scale the load based on your needs. If you have high database demand then you can upgrade your database instance size.
The actual number of concurrent users per server depends mainly on the actual code complexity and work each request has to do. If you have very heavy logic and data processing per request then you need bigger servers sooner, if you have very light fetch and display type requests then you can get a lot more concurrent users at once per server.
In most Enterprise versions you should really have at least 2 front end servers to allow for redundancy and load balancing.
Hi Vikas ,
As described by Jeanene Williams there exactly not any limit for API call from Outsystems and also for the screens you develop in Outsystems.
There are many other factors which are basically the part of your infrastructure design which can let you know the boundaries of your server and application and it is not very much specific to Outsystems rather a common standard.
This also depends upon the server where you API are hosted , how much load that can bear and hence to know the systems boundaries we do load testing of our application by consider the expected load and concurrency for your application.
Outsystems at any point allows you to scale up your environment by adding more front ends to support the incoming load.

Thanks Jeanene & Pramod. Now its quite clear.
Thank you
