Chaos engineering matured at organizations such as Netflix, and gave rise to technologies such as Gremlin (2016) , becoming more targeted and knowledge-based. Thus, the tool Chaos Monkey was born. Any failures in the stack break the hypothesis. Blast radius. That’s a good thing.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two. Modern network performance and availability.

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. The latest AWS hypervisor, Nitro, uses everything to provide a new hardware-assisted hypervisor that is easy to use and has near bare-metal performance. I'd expect between 0.1%

Sites that use an excess of resources, whether on the network or on the device, don’t just cause slow experiences, but can leave entire groups of people out. Similarly, there is a growing gap between what a top of the line network connection can handle and what someone with a poor mobile connection or satellite connection can handle.

Instead of asking that question, I asked them this: “Are you a network or hosting provider?

In 2016, Apache Spark introduced Structured Streaming , a new streaming engine based on the SparkSQL abstractions and runtime optimizations. To run our applications, we require computing system resources like CPU, memory, disk, and network bandwidth to be allocated to the critical data services that power the applications.
