What the historical project actually completed
This article is an independent analysis of an externally documented engineering project. Netflix performed the migration described by its own engineering leaders; this is not an XIVTech engagement, portfolio result or endorsement.
In its February 12, 2016 account, Netflix reported that it completed its cloud migration in early January 2016 after seven years of work, shutting down the last remaining data-center components used by its streaming service. That statement defines a particular workload boundary and time period, not the elimination of every physical infrastructure dependency.

Rearchitecture was part of the method
Netflix's authors distinguish moving unchanged systems from rebuilding for a cloud-native operating model. They describe moving from a monolithic application toward microservices, changing the data model and adopting self-service delivery practices. These are reported decisions from that project, not a prescription that every organization should repeat.
The analytical lesson is to make application and organizational change visible in a migration scope. A plan that lists only infrastructure tasks can hide work needed in data design, release coordination and operating ownership. Whether those changes are appropriate depends on the actual workload and team.
Compute migration did not replace the delivery network
The same Netflix account states that AWS supported its scalable computing and storage, including business logic, databases, analytics and transcoding, while Netflix Open Connect delivered video. Those functions should not be collapsed into a claim that one provider replaced every layer of the service.
AWS's Netflix customer overview corroborates the use of AWS compute, storage and infrastructure. Its current collection also describes newer projects; those newer results must not be treated as measurements of the 2016 migration. This analysis therefore does not combine later database performance claims with the historical completion outcome.
