Trying to compare any metric during this time period can be a futile effort, as obvious in this case where there was no customer impacting shift in the error rate but we cannot interpret that from the chart. We observe that the metric for the new version N+1 stabilizes as the rollout ramps up and reaches closer to 100%, whereas the metric for the current version N becomes noisy over the same time duration. The chart of client-side error rate during the same time period as the version migration is shown here. And the signals to evaluate a new version are derived from comparatively few thousands of homogenous servers instead of millions of heterogeneous devices.Ĭlient-side error rate during the staged rollout In contrast, a server application runs on servers which are typically identical and a routing abstraction can serve sampled traffic to new versions. Hence, the sampling strategy is different if it is a mobile application versus a smart TV. Depending on the type of client, we need to determine the right strategy to sample consumer devices, and provide a system that can enable various client engineering teams to look for their signals. The challenge for clients is that each instance of the application runs on a Netflix member’s device and signals are derived from a firehose of events being sent by devices across the globe. It helps bring a healthy balance to the velocity and quality equation. We are all familiar with the advantages of releasing frequently and in smaller chunks. We have more flexibility to control the distribution of the application in the former than in the latter case. The second is one where an application is hosted behind an app store, for example mobile phones or even game consoles. An example of this is Netflix’s video player or the TV UI javascript package. The first is where an application package is downloaded from the service or a CDN. We deal with two classes of client application updates. The goal of this blog post is to highlight the investment areas for this vision and the challenges we are facing today. As we invested in systems to enable this vision, it led to increased development velocity, which arguably led to better development practices and quality of the applications. Our team was formed to mine health signals from the field to quickly evaluate new versions of the client applications. Hence, it became important to supplement our release decisions with strong evidence received from the field during the update process. However, Netflix is available for streaming on thousands of types of devices and it is powered by hundreds of micro-services which are deployed independently, making it extremely challenging to comprehensively test internally. At Netflix, we have significant investments in ensuring new versions of our applications are well tested. Quality of a client application is of paramount importance to global digital products, as it is the primary way customers interact with a brand.
