Hi,
SAP offers fee-based hosting of IDES. Check this : SAP Integration and Certification Center (SAP ICC) – Integration Scenario - SAP Test System Access
You can register the IDES system on SAP site and request for access key or license key that is required.
https://websmp104.sap-ag.de/notes. Goto Keys & Requests -> SSCR Keys -> Register Developer. is the link to generate developer keys which is unique for each user in each separate installation.
Reference Link: How will we get IDES access key?
Thanks,
DJ
