And also not disagreeing. While not an expert (thankfully!), it was very prescriptive and theoretically suited to the development styles of the time. As you suggest, microservices is more ad hoc and puts a greater burden on good architectural and operations practices which are more informally enforced.

But, net net, I put SOA in the same general bucket as ITIL and other associated practices of the time. They meant well but for most purposes they involved too much process and were ultimately too tied to big vendors trying to sell stuff.
