Maximum concurrent users on application deployed on JCS-SX

How many concurrent users can actually be on an app deployed on JCS-SX for S1, S2 & S4 product descriptions.

I am aware of the limitation on no of server(s) as well as storage size but need assistance on concurrent users limitation, if any from Oracle product specification/configuration.

    This is something that very much depends on an application, isn't it?

    Where one application can serve thousands of users, the other might be able to serve only hundreds, or even tens.

    You are pretty much correct but there is a concern on the subscribed JCS-SX specification of S1 with 5GB storage and only one Java EE server. These factors seem to be limiting the available resources with respect to connection size and co.

    The pricing model is different for PaaS and SaaS. Most SaaS services have pricing based on number of users. For JCS-SX, pricing is based on the configurations (memory, storage, # of Java EE servers).  There are 3 different configuration options available - Java S1, Java S2 and Java S4.

    As Jiri noted in his response, number of concurrent users will depend on the type of application and other factors like how many requests per second are sent to JCS-SX and for how long. I would suggest doing a POC using your application and test with n # of concurrent users to determine the capacity(Java EE servers) that you will need for your JCS-SX deployment. If resources offered in Java S1 configuration does not meet your needs, you can move up to higher configurations like Java S2 or Java S4.
