To this end, we developed a Rapid Event Notification System (RENO) to support use cases that require server initiated communication with devices in a scalable and extensible manner. This separation allows us to tune system configuration and scaling policies independently for different event priorities and traffic patterns.

Dubai - UAE Dubai has grown significantly over the past decades, not just demographically but also in terms of internet penetration. With an internet penetration of almost 92% , the UAE is among the highest worldwide. With Tel Aviv being the technology capital of Israel, it's the ideal edge server location.

This is because HTTP/3 and QUIC mainly help deal with the somewhat uncommon yet potentially high-impact problems that can arise on today’s Internet. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. Websites would magically become 50% faster with the flip of a switch! Did You Know?

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. This server is spending about a third of its CPU cycles just checking the time! Colleagues/Internet I love using [Linux performance tools]. A quick check of basic performance statistics showed over 30% higher CPU consumption.
