Difference Between Solaris and Linux Operating System

A lot of enterprises consider Oracle Solaris to Linux Migration or Linux to Solaris as per the requirement of their applications and database. Before making this decision, an important question is, what is the difference between Linux and Solaris?

Here, in this article, we will discuss a few key differences between these two popular operating systems for you to understand and get clarity on the migration decision you might think of. But before discussing the differences, let’s have an overview of what Linux and Solaris are:


Linux is one of the most popular versions of the UNIX operating system which is based on the Linux kernel. It is one of the fastest-growing OS due to its open-source wide distribution under general public license and low dependency and is quite flexible to work with.

Android is the most successful application by the Linux kernel. Linux has two primary layers i.e. Kernel and User layer in the architecture. Each Linux test distribution is different with a different set of interfaces and can be opted as per the needs of a project.


Solaris is UNIX based operating system developed by Sun Microsystems, almost 2 decades ago. After Oracle acquired Sun Microsystems, it was renamed as Oracle Solaris. Solaris was written in C and C++ programming languages and is designed to function with SPARC and power PCs. Oracle Solaris is known to be efficient and offers high security and performance.

Let’s look at the key differences between Linux and Solaris operating systems.

  • Distribution: Linux is a free, open-source, and quite popular and widely used OS. On the other hand, Solaris requires a license and offers no easy distributions.
  • The future of OS: Linux delivers low TCO, high flexibility and scalability, and reliability in comparison to Solaris. This makes Linux a future-oriented OS.
  • Services: Solaris is mostly used for service management and Linux is used for mobile and embedded services.
  • Popularity: Unlike Solaris, the ability to run on almost any machine as per the user’s configuration needs and a low TCO, and being offered by all cloud service providers (e.g., GCP, AWS, Azure) it is more widely used by users to tackle challenges.
  • Accessibility: Linux is a platform-independent OS while Solaris is not accessible to all the platforms.
  • Development Language: Solaris is developed by using both C and C++ languages and Linux OS is developed by using C language.
  • Ease of Installation: It’s quite easy to install Linux OS by kick start installation whereas solar this OS installation needs an automated installer as a prerequisite.


To sum everything up, Linux is a widely used open-source and easy to install OS whereas Solaris uses licensed software. Both technologies have their own set of advantages and disadvantages, but when it comes to opting for a more efficient and reliable OS, Linux seems like a closer choice.
