Recently I started working on AdxStudio portal for exploring it’s capability and level of customization, I tried with both the options i.e. Cloud hosted by AdxStudio and Self hosted (On my own IIS server). Suddenly I found that AdxStudio has stopped their support for cloud hosted solution. see below screen shot,
Now the only option left is either host this portal on your IIS server or host it on Azure server.
Check out following links for configuring AdxStudio portal into Microsoft Dynamics CRM from local IIS Or Azure,
Why AdxStudio hosted trial of portal is no longer available?
I think Microsoft will provide cloud hosted option under office 365 & same portal will be available as an add on for Microsoft Dynamics CRM. Hope so that will bring more easy option for portal configuration and fast synchronization as both CRM solution & portal will functional from same server location.
