How many buffers are needed to track pending requests as a function of needed bandwidth and expected latency? Can one both minimize latency and maximize throughput for unscheduled work? The M/M/1 queue will show us a required trade-off among (a) allowing unscheduled task arrivals, (b) minimizing latency, and (c) maximizing throughput.

Put another way, the performance gap between what devices the wealthy carry and what budget shoppers carry grew more this year (252 points) than the year-over-year gains from process and architecture at the volume price point (174 points). So what did $650, give or take, buy in late 2017 or early 2018? That's where the good news ends.

In 2018, a widespread adaptation of Kubernetes for big data processing is anitcipated. For instance, scatter/gather pattern can be used to implement a MapReduce like batch processing architecture on top of Kubernetes. Kubernetes has emerged as go to container orchestration platform for data engineering teams.

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.

India became a 4G-centric market sometime in 2018. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. More frequently, "app"-centric architectures promulgated by popular framework starter kits leave teams with immense piles of JS to whittle down.

One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Keeping progressive enhancement as the guiding principle of your front-end architecture and deployment is a safe bet. Consider using PRPL pattern and app shell architecture. Use progressive enhancement as a default.
