In the latest post (check in the comments), a team that works on Prime Video explained their approach to ensuring that customers receive high-quality content. They use a tool to monitor every stream viewed by customers and use it to identify quality issues.
The tool was intended to run on a small scale, so they noticed that ๐ผ๐ป๐ฏ๐ผ๐ฎ๐ฟ๐ฑ๐ถ๐ป๐ด ๐บ๐ผ๐ฟ๐ฒ ๐๐๐ฟ๐ฒ๐ฎ๐บ๐ ๐๐ผ ๐๐ต๐ฒ ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ ๐๐ฎ๐ ๐๐ฒ๐ฟ๐ ๐ฒ๐

Building initial solutions with serverless components was a good choice because it enabled it to be done quickly and scale each component, yet such a way of using some components ๐ฐ๐ฎ๐๐๐ฒ๐ฑ ๐ถ๐๐๐๐ฒ๐ ๐ฎ๐ ๐ฑ% ๐ผ๐ณ ๐๐ต๐ฒ ๐ฒ๐

After the analysis, they concluded that the distributed approach didn't bring many benefits, so they packed all the components into a single process. ๐ ๐ผ๐๐ถ๐ป๐ด ๐๐ต๐ฒ๐ถ๐ฟ ๐๐ฒ๐ฟ๐๐ถ๐ฐ๐ฒ ๐๐ผ ๐ฎ ๐บ๐ผ๐ป๐ผ๐น๐ถ๐๐ต ๐ฟ๐ฒ๐ฑ๐๐ฐ๐ฒ๐ฑ ๐๐ต๐ฒ๐ถ๐ฟ ๐ถ๐ป๐ณ๐ฟ๐ฎ๐๐๐ฟ๐๐ฐ๐๐๐ฟ๐ฒ ๐ฐ๐ผ๐๐ ๐ฏ๐ ๐ผ๐๐ฒ๐ฟ ๐ต๐ฌ% ๐ฎ๐ป๐ฑ ๐ถ๐ป๐ฐ๐ฟ๐ฒ๐ฎ๐๐ฒ๐ฑ ๐๐ฐ๐ฎ๐น๐ถ๐ป๐ด ๐ฐ๐ฎ๐ฝ๐ฎ๐ฏ๐ถ๐น๐ถ๐๐ถ๐ฒ๐.
