The Rise of Android

Embedded and Mobile Systems

With the release of Android, which is based on the Linux kernel, Linux achieved enormous popularity in the mobile market. Since Google's 2008 introduction of the first phone running Android, Android has taken the lead in the global smartphone industry.

Android: Despite its considerable departure from conventional Linux distributions, Android's adoption of the Linux kernel guaranteed that Linux would eventually overtake other OS kernels as the most popular on mobile devices.

Embedded Systems and IoT: Linux is also widely used in embedded systems, the operating systems inside devices like routers, smart TVs, and automotive infotainment systems. Linux’s flexibility, lightweight nature, and open-source model make it ideal for Internet of Things (IoT) applications.
Supercomputing, servers, and the cloud.

For many years, Linux has dominated supercomputing, cloud, and enterprise operating systems. It is perfect for powering contemporary infrastructure because of its scalability, security, and open-source nature.

Cloud, Server and Super Computing

• Cloud computing: Linux became the standard operating system for the cloud as a result of the growth of cloud platforms such as Microsoft Azure, Google Cloud, and Amazon Web Services (AWS). Today, Linux powers most cloud instances, and Linux containerization is the foundation of cloud-native technologies like Docker and Kubernetes.
• Supercomputers: The industry leader in supercomputing is Linux. The top 500 supercomputers worldwide are all Linux-based as of 2024, and many of them use customized OS versions made for their particular hardware.
• Enterprise Servers: Linux remains the go-to choice for enterprise servers. Red Hat Enterprise Linux (RHEL), CentOS, and SUSE Linux Enterprise Server (SLES) are widely used in businesses for web hosting, databases, and critical infrastructure.

Key Linux Technologies

Linux development has introduced several important technologies that have influenced computing worldwide:

• Linux Containers and Docker: Containers have revolutionized application deployment by isolating applications and their dependencies. Docker, which popularized containers, runs on Linux, and Kubernetes, the leading container orchestration platform, is also based on Linux.
• Systemd: Introduced in 2010, Systemd replaced older init systems and is now the standard for managing services and boot processes on most Linux distributions.
• SELinux: Security-Enhanced Linux (SELinux) is a Linux kernel security module that provides mandatory access control (MAC) and improves security, especially in sensitive environments like government or enterprise servers.
