Hi,

what about docplexcloud and security ?

As can be read at https://developer.ibm.com/docloud/documentation/decision-optimization-on-cloud/pricing-plans-and-free-trial/

What happens to my data?

Data submitted to DOcplexcloud is stored in a secure object store. Only the DOcplexcloud Operations Team has access to the object store and all connections are secure (https). Data is uploaded to DOcplexcloud when a job is submitted and exists only in the system while the job exists. Your data is encrypted in the object store using a single encryption key controlled by the DOcplexcloud Operations Team. As soon as a job is deleted in the system, all associated customer data is also deleted.

On top of that, you may also use the compiled model feature :

From the IDE, you can generate a compiled model. A compiled model is a binary version of a .mod file.

Keeping your models as compiled files may help you protect your intellectual property because these binary files are not human-readable.

But this .opl file is not yet an input file for docplexcloud in https://developer.ibm.com/docloud/documentation/docloud/supported-file-types/

The way to go is simply to rename the .opl file into a .mod file and then everything works fine.

Let me give you a tiny example:

let me give you an example

take the model

// 300 kids bus 40 bus 30 , 50 40
 
int nbEnfants=300;
float coutbus40=50;
float coutbus30=40;
float coutbus40apres5=45;
 
dvar int+ nb40;
dvar int+ nb30;
 
minimize piecewise{0->0;coutbus40->5;coutbus40apres5}   nb40  +nb30*coutbus30;
 
subject to
{
40*nb40+nb30*30>=nbEnfants;
 
}

You compile that into zoocrypt.opl

and then you rename that into zoocrypy.mod

Inside you have

This is crypted

But you can run that in docplexcloud
