Netflix ended the last datacenter, now everything is on the cloud

It is done. Since last January, Netflix is all about the cloud. The transition to the cloud has been a long-running process for the video-streaming service, which began back in 2008 and ended in one day unspecified last January. Netflix works now through Amazon Web Services (AWS), the cloud that is essential to give managers the maximum horizontal scalability, and users with the best performance. The operation of the service is done now everything exclusively in the cloud, from the management of employees to customer data.


As important, the current date is nothing more than the elimination of the last bits inside the Netflix data center owners. From time most of the contents of Netflix is ​​offered in leveraging cloud technologies, with data centers that can no longer serve the company views the incredible expansion recorded over the years. Since 2008 Netflix has eight times the number of subscribers with greater activity on the part of each of these. The latest transposed parts cloud were not related to streaming and content, but to the customer data management and staff of the company.

Netflix could simply take all the contents of its data centers and schiaffarli in the cloud. But he did not. The migration to the cloud took place simultaneously with the transformation of the whole company, with the gradual evolution of the process that offered over time new information and gave the opportunity to adopt new approaches. Thanks to the cloud on the structural Netflix plan is no longer monolithic application, such as seen today its users, but a series of micro services linked one with the other in which each team can make independent decisions.

The cloud has allowed Netflix to expand more easily service the new nations and to drastically improve also its availability to users, with the down periods more limited and less widespread scale. Although this was not the main reason for moving to the cloud, the migration has allowed the service to reduce the cost per stream. The new infrastructure is more flexible and can be magnified or reduced according to actual needs, differently from a monolithic data center in which installations and upgrades take longer and, above all, money.
