It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?

MongoDB is the #3 open source database and the #1 NoSQL database in the world. So, what makes DigitalOcean a compelling alternative to other popular MongoDB hosting providers like AWS and Azure ? DigitalOcean, along with AWS and Azure, offer a 99.99% uptime SLA, but while that sounds close to perfect, that 0.01% equates to 52.6

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Over the years, these patterns have been implemented by numerous products, ranging from commercial ESBs and enterprise message buses to open source libraries and products. The Alpakka project is an open source library initiative to implement stream-aware, reactive, integration pipelines for Java and Scala.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. There are many tools allowing you to achieve that: SiteSpeed.io Large preview ).
