Welcome to this three-part mini-series on real-time Linux. In Part I, we set the stage for the remainder of the series by defining a real-time system, and went through common misconceptions. We also covered the broad market applications of a real-time Linux kernel. Several applications across a wide range of use cases and verticals require real-time computing capabilities. Sectors like industrial automation, energy and transportation have strict precision requirements for their systems.

Gartner forecasts that worldwide end-user spending on public cloud services will grow 20.7% from $490.3 billion in 2022 to $591.8 billion in 2023. By 2026, the Public Cloud market will double its size today to $1 trillion, also predicted by Gartner. AWS, Microsoft Azure, and Google Cloud all maintained double-digit growth in Q4 2022, especially Google Cloud grew 32% to $7.32 billion. CDN giant Akamai also unveiled Akamai Connected Cloud and New Cloud Computing Services on Feb 14, 2023.

As Mobile World Congress 2023 approaches, the latest technological advances in the telecom industry will take center stage. At the forefront of these advances are the innovations brought about by open-source technologies. At Canonical, we are leading the way in this space, with groundbreaking developments in OpenRAN automation and distributed compute management that outperform our competition.

Welcome to this three-part blog series on real-time Linux. Throughout the series, we will assess the key features of a real-time system. We will understand how a real-time capable Linux kernel differs from mainline, and touch upon the performance trade-offs you should consider when choosing real-time versus a low-latency kernel, for instance.

5G is the fifth generation of wireless technology which is transforming the way we connect and communicate. With data transfer speeds up to 100 times faster than 4G, 5G technology enables faster download and upload times, lower latency and a higher number of connected devices. Additionally, 5G networks will support a wider range of frequencies, including high and low bands, which will ensure wider coverage and greater reliability.

At Canonical, we often get questions about open-source security and of course, Linux security is a common topic. Based on a recent webinar hosted by our security team and an accompanying blog post, we put together the most common questions we receive. This is by no means an exhaustive list, but it should give you a general idea about Ubuntu’s approach to security vulnerability management, livepatch, IoT, and its compliance and hardening tools.

ERLANGEN, Germany, and DOUGLAS, Isle of Man, February 21, 2023 – Elektrobit and Canonical today announced EB corbos Linux – built on Ubuntu, an industry first bringing the largest open-source Linux community to automotive software. Available immediately from Elektrobit, the new solution provides OEMs and Tier 1 suppliers with the benefits and flexibility of an open-source operating system for developing electronic control units (ECUs) in software-defined vehicles.
