Yesterday, Today and tomorrow : Embedded Linux

Embedded Linux has come a long way since its inception. Yesterday, embedded systems were primarily focused on running a small, custom-built kernel with limited functionality. Linux was not the default choice for embedded systems, and if it was used, it was a heavily stripped-down version of the operating system.

Today, however, Embedded Linux has become the preferred choice for embedded systems due to its flexibility, scalability, and availability of a wide range of open-source software libraries. Linux-based embedded systems are now used in a variety of applications, including consumer electronics, automotive, healthcare, and industrial automation.

One of the most significant developments in Embedded Linux over the last few years has been the advent of the Internet of Things (IoT). The ability to connect embedded devices to the internet has led to the creation of a new generation of smart and interconnected devices, such as smart thermostats, smart lighting, and connected cars.

Another significant development has been the rise of containerization and virtualization in the embedded space. Containerization allows developers to create lightweight, isolated environments that can run on a variety of hardware platforms, making it easier to deploy and manage applications in embedded systems. Virtualization, on the other hand, enables developers to run multiple operating systems on a single device, allowing for greater flexibility and improved resource utilization.

Looking towards tomorrow, Embedded Linux is expected to continue to grow in popularity as the demand for smart, connected devices increases. With the emergence of 5G networks and edge computing, embedded devices will become more powerful and capable of running more sophisticated applications. The development of new technologies, such as artificial intelligence and machine learning, will also have a significant impact on the embedded space, enabling new applications and use cases.

Embedded Linux has evolved significantly over the years, from a niche technology to a mainstream choice for embedded systems. The IoT, containerization, and virtualization are just a few of the many developments that have shaped Embedded Linux today. Looking forward, we can expect to see even more exciting advancements as technology continues to evolve and the demand for smart, connected devices continues to grow.
