What is the difference between BELOW: 1)Midsourcing Server 2)Marketing Server 3)RT Server 4)Execution Server

Hi @shruti1 

This addresses the architecture principles for Adobe Campaign and it can be a lengthy topic to discuss,

IN a nutshell:

Marketing: this is the core instance where marketers define and execute their campaigns

Mid-Sourcing: for very large customers and for hybrid hosting model, instance that sends the delivery physically , this instance is also where you would create your transactional message templates and your offers

RT: stands for Real-time aka transactional messages such as forgot password, confirmation messages, etc... instance that send messages in real-time from an event occuring on the 3rd party application

Execution Server: other name for the RT instance. In the context of inbound offer management this is the instance that will actually process the offer request

I invite you to review the online documentation where these are explained

Hosting Model: https://experienceleague.adobe.com/docs/campaign-classic/using/installing-campaign-classic/architecture-and-hosting-models/hosting-models-lp/hosting-models.html?lang=en

Hope this helps,

Thanks
