OCTOBER 19, 2020

Reconstructing a streaming session was a tedious and time consuming process that involved tracing all interactions (requests) between the Netflix app, our Content Delivery Network (CDN), and backend microservices. Our engineering teams tuned their services for performance after factoring in increased resource utilization due to tracing.

As database performance is heavily influenced by the performance of storage, network, memory, and processors, we must understand the upper limit of these key components. For the network, we can use Iperf to assess the network bandwidth between the client and the database server to ensure it will be enough to meet our peak requirement.

Eclipse is open source and has all of the features you’d expect out of an IDE such as PHP profiling, syntax highlighting and unit testing; however, it requires a lot of resources to run, which could present an issue for smaller development teams. PHPUnit is particularly useful for consistency and scalability testing.
