As part of the How, it is important to understand that all campaigns will share a common set of building blocks which we call infrastructure. These are message brokers, security mechanisms, etc. that will be share by all campaigns. For us to be fast and develop and deploy new campaigns quickly a running infrastructure must be in place so multiple campaigns can share the common bits. At the same time, it is important to notice that even if we share common infrastructural services, we should be able to scale each campaign independently.
