I was going through Azure new offering Digital Twin and trying to understand what makes it different and unique so that organization will use it and will not invest in developing theirs own DT systems.
I also posted the question on https://channel9.msdn.com/Shows/Internet-of-Things-Show/Getting-started-with-Azure-Digital-Twins?term=%22Azure%20Digital%20Twins%22&lang-en=true and got the response for https://techcommunity.microsoft.com/t5/azure-iot/at-the-end-of-the-day-what-is-digital-twins-about/m-p/759502#.XS9eIPFF0Pc.link
All links explains the functional details but nowhere it is mentioned what are the core components for building ADT, internal details and how much effort goes to build one w.r.t to using Azure offering. obviously, it is PaaS offering so it will always beneficial to use one then creating one but what are components will need to create one.
Thanks
