Scalable I/O: Events- Vs Multithreading-based

Everything begins with a refresher reading of my fundamental papers – yes, I use a set of papers and books as reference material. This paper is titled: “Why Events Are A Bad Idea (for high-concurrency servers)“, by Rob von Behren at the time of writing a PhD fellow at Berkeley [18]. Von Behren opens with: “Event-based… Continue reading Scalable I/O: Events- Vs Multithreading-based

Dense Virtualization via Linux Containers

We are living the era of buzzwords, and Docker is for sure one of those in the technological landscape. Docker has a common sense definition: hypervisor-free virtualization. In other terms: running VMs without any hypervisor-based virtualization support. Now, how is this possible? What is the arcane trick to achieving that? Let’s live a short journey… Continue reading Dense Virtualization via Linux Containers

Pills of Eventual Consistency

A question raises spontaneously: why Eventual Consistency? Isn’t ACID enough? Let’s try to understand the need for Eventual Consistency guarantees when we talk about Distributed Computing on large scale, and of course Data is involved. With the advent of Internet and Cloud services, Databases and more in general Data Storage technologies have undergone a radical change:… Continue reading Pills of Eventual Consistency
