This architecture shift greatly reduced the processing latency and increased system resiliency. We expanded pipeline support to serve our studio/content-development use cases, which had different latency and resiliency requirements as compared to the traditional streaming use case. divide the input video into small chunks 2.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. How would you _time_ time?

When I joined Netflix in April 2014, we had over 40 million subscribers in 41 countries. We're on the EC2 cloud, which has great scalability, and our own cloud architecture of microservices is also designed for scalability. A latency outlier issue that happened every 15 minutes.

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. Xen's biggest user is the Amazon EC2 cloud, which has over one million customers, and appears to be a custom version (it self identifies as version "3.4.3.amazon").
