Hosted vs Hybrid Model

Hello @neelamb91 you have official docs here

However, mainly these are diff:

AC Hosted - If you opt for a hosted deployment option for Adobe Campaign, your solution will be hosted in one of Adobe’s data centres.

The advantages of a hosted solution are that you can pass the responsibility for uptime and performance over to Adobe. You have access to most Adobe Campaign Classic modules and you’ll also have greater access to product expertise, better security and reduced costs of in-house support staff.

However, it does mean relinquishing a degree of control. In addition, if you’re looking to process information stored in one or more external databases – known as the Federated Data Access (FDA) module, the hosted deployment option won’t work for you.The external database needs to be exposed to the Campaign server and, as a result, FDA is not available for managed service deployments. You also won’t be able to use the LDAP configuration module.

AC Hybrid - A hybrid solution is one that combines the on-premise and hosted deployment options. In other words, you host some parts of the solution, while Adobe hosts others. When it comes to Adobe Campaign Classic, Adobe typically hosts cloud-based messaging services, whilst you host the data-specific components of the solution – including integration components – on-premise.

If you can’t quite decide between on-premise or hosted, hybrid hosting might be right for you. It provides a comfortable middle ground, where you have control over some areas and not others. In addition, you have all modules available to you.
