Translator's note: this material is from the educational project learnk8s — an answer to a common question when designing infrastructure based on Kubernetes. We hope that the sufficiently detailed descriptions of the pros and cons of each option will help make the optimal choice for your project. TL;DR: the same set of workloads can be run on multiple large clusters (for each cluster...

Hello, Habr! In light of the current events due to coronavirus, many online services have experienced increased load. For example, one retail chain in the UK simply shut down its online ordering site due to insufficient capacity. It's not always possible to speed up a server just by adding more powerful hardware, but customer requests must be processed (or they will turn to competitors). In this […]
Greetings, everyone! My name is Nikita, and I am the team lead of the engineers at Cian. One of my responsibilities at the company is to reduce the number of incidents related to infrastructure in production to zero. What I will discuss next has caused us a lot of pain, and the goal of this article is to prevent others from making our mistakes or at least minimize their impact. […]
It's probably no secret that last year was a year of significant changes for Apache Hadoop. Last year saw the merger of Cloudera and Hortonworks (essentially, the acquisition of the latter), while MapR, due to serious financial issues, was sold to Hewlett Packard. A few years ago, the choice for on-premises installations was often between Cloudera and […]
Microsoft has released the Rust/WinRT toolkit, enabling the use of the Rust language for developing applications based on the WinRT (Windows Runtime) architecture. The code associated with the project is published under the MIT license. Rust/WinRT allows developers to create applications similarly to C++/WinRT using the standard tools of Rust, enabling calls to any existing or future WinRT APIs using code generated on-the-fly from metadata, […]
An experimental version of the Firefox Preview 5.0 browser has been released for the Android platform, developed under the codename Fenix as a replacement for the Firefox edition for Android.

The developers of the Xfce project have announced the completion of the transition to a new development infrastructure based on the GitLab platform. Previously, access to the code repositories was provided through a combination of cgit and gitolite. The old server git.xfce.org has been switched to read-only mode, and it is recommended to use gitlab.xfce.org instead. The migration to GitLab will not result in changes affecting users and package maintainers, but […]
Today, the scripting language Tcl/Tk is used not only on computers but has also been successfully ported to the Android platform. However, it is precisely on this platform that all the shortcomings of the file selection dialog in tcl/tk (tk_getSaveFile, tk_getOpenFile, or tk_chooseDirectory) have become particularly evident. What are the issues with this dialog? The lack of basic operations for folders/files: create, destroy, rename. No, don't get me wrong, in […]
Hello everyone in this blog, and welcome to the fourth post in the Quarkus series! The previous post discussed how Quarkus integrates MicroProfile and Spring. Recall that Quarkus is positioned as 'super-fast subatomic Java,' or 'Kubernetes-oriented Java stack optimized for GraalVM and OpenJDK HotSpot, built from the best libraries and standards.' Today we will show how to modernize […]
