. Phones for those who just need to make calls - without amazing cameras, three SIM card slots, a fantastic screen and a powerful processor - have not gone away. Now such "dialers" are trying to provide resources for comfortable browsing and "facilitate" other software. We tell who uses such devices (not only those who cannot afford top flagships), why there is a demand for them, and what does the cloud have to do with it.
. The material is completely devoted to the hot - more precisely, the fight against it. We discuss ways to cool equipment in data centers: the pros and cons of water, the combined option with air, natural cooling and its risks. We do not forget about the role of new artificial intelligence systems in these processes and the demand for environmentally friendly solutions.

. In this article, we discuss the situation around high-performance computing based on an open OS. We talk about its advantages in this area - from performance to customization - and talk about the development of new supercomputers that will be able to use the system in the near future.
. The system will soon be thirty years old! We recall the context in which it appeared, and here Multics, enthusiasts from Bell Labs and the βfatefulβ printer.
. We continue the story of the development of this operating system with a focus on its commercialization: the emergence of Red Hat, the rejection of free distribution and the development of the corporate segment. We also discuss why Bill Gates tried to reduce the importance of Linux, how his company lost its monopoly in the market and got a new competitor.
. We are ending the cycle of βwell-fed zeroβ - with Ubuntu, which was supported by Dell, competition from Windows XP and the advent of Chromebooks. At this time, the era of smartphones began, where an open OS became a reliable foundation. We talk about this and the further development of the technological ecosystem and the IT community around Linux.

. Over the past ten years, cloud technologies have evolved a lot, but some misconceptions about how they work and the functioning of IaaS providers still circulate. In the first part of our large analysis, we explain who works in technical support, how everything works in 1cloud, and why virtual infrastructure management is available to any manager.
. We continue to analyze the most popular myths about the cloud. In the second part, we tell you how you can work with business-critical applications on the infrastructure of an IaaS provider, give examples, discuss 1cloud platforms and customer data protection technologies.
. We complete the cycle of materials with an analysis of issues related to hardware. We start with an overview of the situation - where the industry is heading, what resources companies are investing in the construction of data center infrastructure. And don't forget to share your experience.
