Linux is an open source operating system (OS). An operating system is the software that directly manages a system's hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work. Below listed are few professionals who can learn Linux:

• Anyone who wishes to learn Linux and take their careers to the next level.
• Fresh graduates

Linux Certification Training aids an aspirant to become a master in Linux. It sharpens the skills by providing comprehensive knowledge of ETL Processes, and proper hands-on experience for solving real-time and capstone projects which encompasses data integration and big data projects.

Our instructors are the Industry Experts who have experience with Linux tools in IT industries. Upon completion of the course, the following concepts are understood and mastered by the students.

Linux is a free and open-source operating system kernel that serves as the core of many different operating systems, commonly referred to as "Linux distributions" or "Linux distress." It was created by Linus Torvalds in 1991 and has since gained widespread popularity and adoption.

Here's why Linux is considered an important and continually growing technology:

Open Source: Linux is open source, which means its source code is freely available for anyone to view, modify, and distribute. This open nature fosters collaboration, innovation, and a vast community of developers and users worldwide who contribute to its development and improvement.

Stability and Reliability: Linux is known for its stability and reliability. It is widely used in critical systems, such as servers, where uptime is crucial. Many internet servers, supercomputers, and embedded systems run on Linux because of its ability to handle high loads without crashing or requiring frequent reboots.

Security: Linux is renowned for its robust security features. Its open-source nature allows the community to quickly identify and address security vulnerabilities. Additionally, the access control mechanisms and user privileges system are well-designed, making it more resistant to malware and other security threats.

Customizability: Linux offers a high degree of customization. Users can choose from a variety of desktop environments, package managers, and software options to create a computing environment tailored to their specific needs and preferences.

Cost-Efficiency: Linux is free to use, which significantly reduces the total cost of ownership, particularly for businesses and organizations. There are no licensing fees, and it can run on a wide range of hardware, including older or less expensive hardware.

Community Support: The Linux community is vast and active. Users can find a wealth of documentation, forums, and online resources for troubleshooting issues, learning, and sharing knowledge. Many companies also offer commercial support for Linux-based systems.

Versatility: Linux is versatile and can run on various devices, from servers and desktop computers to smartphones, embedded systems, and IoT devices. Its versatility makes it a go-to choice for a wide range of applications and industries.

Growing Adoption: Linux's popularity continues to rise across various domains, including cloud computing (with platforms like AWS, Azure, and Google Cloud), mobile devices (e.g., Android), and even on the desktop (with distributions like Ubuntu and Fedora). It is considered a key player in the technology landscape.

Innovation: Linux serves as a foundation for many cutting-edge technologies. For instance, it plays a significant role in the development of containers (e.g., Docker) and container orchestration (e.g., Kubernetes), enabling modern software deployment and management practices.

Longevity: Linux has been around for decades and has demonstrated its staying power. Its continued development and adaptation to evolving technology trends suggest it will remain a prominent player in the future.

Overall, Linux's combination of open-source principles, stability, security, versatility, and strong community support positions it as an on-going star in the world of technology. Its influence extends beyond just the operating system, impacting various aspects of the modern computing landscape.

Linux certification refers to a formal recognition or qualification that demonstrates an individual's proficiency and expertise in working with the Linux operating system and related technologies. These certifications are typically offered by various organizations, including the Linux Professional Institute (LPI), Red Hat, CompTIA, and others, and they are designed to validate a person's knowledge and skills in specific areas of Linux administration, development, or other related roles.

There will also be quizzes that thoroughly reflect the type of questions asked in the certification exams at the end of this Linux online training program. They will enable you to score better.

When you complete the project work and score at least 60% marks in the quiz, the Linux course completion certificate will be awarded to you by Greens Technologies. This certification is honoured in the top 80+ multinational companies, such as Gnat, Cisco,Ericsson Cognizant, TCS, Sony, Mu Sigma, and Standard Chartered, etc.
