Hi Diogo,

What kind of logic is executed when the form is submitted?

Enterprise applications should be predictable, meaning they must remain consistent and reliable across different scenarios. To ensure your application can scale to handle 2000 concurrent users, you should perform load testing using a tool like K6. The results will help determine whether you need horizontal scaling (adding more frontend servers) or vertical scaling (increasing the capacity of your existing servers), or possibly both.

Hi Diogo,

You should execute the following steps to prepare for a successful launch.

1. Based on expected concurrent users / peek performance, using the Sizing OutSystems Platform page, calculate the recommended setup of your front-end servers (Quantity, CPU, Memory) and database server (CPU and Memory).

2. If you have a Pre-Production environment, the request scale up of the FE servers and Database Server as based on calculations of step 1. If you don't have a Pre-Production environment, then ask for scale up of the production environment.
   
   
3. Plan & Execute a load test to validate peek performance. If you don't have the expertise, consider hiring a company who is specialized in this. If you search you will find several documentations, webinars, or YouTube videos on how to do load testing. My advice is hire experts to do this job.
   
   Make sure you following also the steps highlighted here:

4.  Based on the load test results, reconsider the sizing of Front End Servers, and Database server, and execute the the load/stress test again. 

To add new Front-end servers see:

If you use OutSystems in the cloud hosted by OutSystems, create support cases for horizontal scaling of front end servers and vertical scaling (CPU, Memory) of Front-end servers and database server.

Hi @Diogo Barbosa ,

I fully agree with Daniel’s proposal. Based on your description, I believe the matter should be handled by someone with experience, ensuring that the solution implemented is the most suitable for the specific case.

The costs associated with an incorrect implementation can lead to unnecessary expenses. For example, if this form is used only for a few days each year, we would be spending financial resources all year round to support something that happens only occasionally, on predictable dates.
