These 4 patterns seem quite simple at first sight, but that’s what patterns are for. They act as a sieve to identify which components are specific to a business application and which are a common pattern of many applications so that we can design the architecture that is not a plate of spaghettis.
In the case of IBISA (https://www.linkedin.com/company/ibisa-network/) we aim to provide a P2P mutual risk sharing without an insurer in the middle, and this is dedicated to cover small crops from droughts and excess rain. We lower costs of damage assessment by doing crowd-watching on satellite images.
From the 4 patterns here, we use for crowdwatching the first one (IAM-Identity Access Management) and the second one (auditable workspace).
