AWS EC2 link to MATLAB online

I am trying to run paralle computing on AWS EC2 using MATLAB online ,

I got an error on validating the cluster,

Is it possible to run AWS EC2 it in the MATLAB Online , and how I can do it?

If I have my codes correct, you're running MATLAB with a commerical license and MATLAB Parallel Server with an academic license. Contact Technical Support ([e-mail]) to help remedy this.

What I find that I couldn’t do it because the limitations of online MATLAB

Hi Roaa - Thank you for your feedback. Can you provide more details into the steps you are trying? You should be able to access and AWS cluster through MATLAB Online via the Cloud Center (https://www.mathworks.com/videos/scale-matlab-online-to-an-aws-cluster-with-matlab-parallel-server-1594643587590.html). Are you still getting the same error as you posted above?

I've attached a screen shot showing MATLAB Online (R2021b) starting a parallel pool of 2 workers. You'll see the MATLAB client is running on machine 1e17d40dd30b and the pool of workers is running on a single node (that's how I designed the cluster) labeled ip-10-0-33-80.

I've also attached the validation results of the AWS-based profile.

Many thanks for your answer, but still I couldn't connect, attached what I got when I tried it :

I have contacted the support to fix it but they didn't, Can you help me to solve it?

Hi @Roaa Alnafea, I've spoken with Support. There was a misunderstanding, which has been cleared up. They should be in touch with you shortly. The gist of it is that you are logging into MATLAB Online with a MWA (MathWorks Account) that is associated with a commerical license (code 300), but you started MATLAB Parallel Server via Cloud Center with an EDU license (code 200). Those codes need to align (that is, you can't use a commerical MATLAB license to submit jobs using an educaitonal MATLAB Parallel Server license).

Yes I understand the problem, but I couldn’t solve it , Thank you for your efforts and I am waiting for the support to solve it .
