Technologies for Computing: From Call-Only Phones to the Cloud and Linux Supercomputers

This is a digest of analytical and historical materials on various technologies for computing – from open source software and the cloud to custom gadgets and supercomputers running Linux.

Will the cloud save ultra-budget smartphones. Phones for those who just need to call – without amazing cameras, three compartments for sim cards, a fantastic screen and a powerful processor – have not gone anywhere. 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 where does the cloud come from.

Data Center Cooling Technologies. The material is fully devoted to the hot – or rather, the fight against it. We discuss ways of cooling equipment in data centers: the pros and cons of water, the combined version with air, free cooling and its risks. Do not forget about the role of new artificial intelligence systems in these processes and the request for environmentally friendly solutions.

Supercomputers Prefer Linux. 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 history of Linux: how it all began. The system will soon be thirty years old! We recall in what context it appeared, and here Multics, enthusiasts from Bell Labs and the “fateful” printer.

The history of Linux: corporate twists and turns. We continue the story about the development of this operating system with a focus on its commercialization: the advent of Red Hat, the rejection of free distribution and the development of the corporate segment. We are also discussing why Bill Gates tried to reduce the importance of Linux, how his company lost its monopoly in the market and gained a new competitor.

The history of Linux: new markets and old “enemies.” We conclude the cycle “full of zero” – with Ubuntu, which was supported by Dell, the competition with Windows XP and the advent of Chromebook. 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.

Cloud Myths. Over the past ten years, cloud technologies have decently pumped, but some misconceptions about their work and the functioning of IaaS providers are still circulating. In the first part of our big discussion, we explain who technical support works, how everything works in 1cloud, and why virtual infrastructure management is available to any manager.

Cloud technologies. We continue to analyze the most popular cloud myths. In the second part, we talk about how you can work with business-critical applications on the infrastructure of an IaaS provider, provide examples, discuss 1cloud platforms and client data protection technologies.

Iron in the cloud. We conclude the cycle of materials by analyzing issues related to hardware. We start with a review of the situation – where the industry is heading, what resources the company invests in building data center infrastructure. And do not forget to share experiences.

What else do we have on Habré:

  • Who and why wants to make the Internet “shared”
  • What services do you miss?
