Testing, Experimenting, Documenting experiences on high performance and scalable stuff
Call for Papers! ADIDSE IARIA Special Track aims at tackling the problems and discussing the advancements in Data-Intensive Distributed Systems Engineering with the community of Engineers and Scientists out there. Come and join us… The advent of the IoT (Internet of Things), by forecasts, is going to bring 40 Billion connected devices by 2020. Such… Continue reading Advancements in Data-Intensive Distributed Systems Engineering
Knot is a network server as well as Haboob. The difference is the concurrency model: Knot is thread-based, instead Haboob is event-based [9]. Clearly, from the benchmark results, the poll()/epoll() mechanism is a serious bottleneck as soon as the number of active concurrent clients become relevant (in the specific case, at 16384 clients the trashing… Continue reading Scaling to Thousands of Threads
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
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
Why to start with an image? Simple, it’s generally recognized that 1 picture is worth 1000 words! And, this is really true for Engineers… WMware Cloud Management Blog proposes an interesting article on the CQRS (Command and Query Responsibility Separation) Architectural Pattern an its applications, a worth reading. In this short blog post, few more… Continue reading Command and Query Responsibility Separation
