This really seems like such a great topic. It was content I was hearing for the first time, and this... even though I'm experiencing practical work, as someone who has only developed general APIs, it was such a beneficial topic that really showed me how wide the world is.. Thank you so much for creating such a great topic. As for the advantages, I could learn a lot from the architecture itself, and it was so great to be able to encounter the really unfamiliar concept of workflow at such an affordable price.
