Written with insight from Antoinette O’Sullivan, Director of Training and Documentation for Linux and Virtualization
Operating systems, containers, and virtualization are the fundamental building blocks of modern IT infrastructure.
Operating on your choice of hardware—in your data center or in the cloud – the Linux Operating System provides the reliability, scalability, security, and performance for demanding enterprise workloads.
The open source Linux kernel, in conjunction with tools, applications, and services bundled along with it, make up the efficient operating system called Linux.
If you're looking for reasons to learn Linux, the future earning potential for Linux professionals is looking bright.
According to an annual tech survey performed by Dice, salaries for Linux professionals in the United States come in at over $100,000 annually, higher than the average $92,000 for tech pros nationally.
To capitalize on this demand for Linux professionals, it's essential to develop in depth Linux administration skills.
Consuming the training content within the Linux Learning Subscription will help you understand and administrate the Linux Operating System. Identify with other key building blocks present in today's IT infrastructure.
The knowledge you gain through this subscription can help transform your IT department from a cost center to a source for modernization.
Take training any time, starting and stopping as needed: it’s tough to take time away and dedicate multiple days to learning; this subscription lets you access continuously updated digital content 24/7 for 1 year, when your schedule allows.
Go above and beyond general knowledge; develop marketable Linux expertise that dives deeply into specific areas: dynamically filter to view subscription content that's laser focused on individual areas of Linux. Simply choose a topic-based channel and start learning.
Get targeted training that will empower you to get hired: view content that is custom designed to train you for specific job roles that work with Linux.
Stay on top of the latest Linux releases, in real-time: interact with new course modules as they're released and watch expert webcasts.
Beyond administrating the Linux Operating System itself, the Linux Learning Subscription includes one year of continuous access to content covering topics like Docker, Oracle Ksplice, OpenScap and the Linux Auditing System.
Watch on demand video courses to learn OpenStack, Pluggable Authentication Modules (PAM) and Security Enhanced Linux (SELinux). Topics like Kubernetes will be available soon, as will others as they are developed.
Subscription content is not only relevant to Oracle Linux administrators, but also to Red Hat and CentOS administrators as well.
Learn more about these key topics, dive into Linux capabilities that enhance your business outcomes and interact with Linux instructors as you develop the skills you need.
Containerization is a key topic for IT departments today when virtualization and portability are key.
According to a Linux.com article, “Docker is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. This helps enable flexibility and portability where the application can run, whether on premises, public cloud, private cloud or bare metal.”
Building on top of capabilities provided by the Linux kernel, a Docker container does not require or include a separate operating system. It relies on the kernel's functionality and uses resource isolation for CPU and memory and separate namespaces to isolate the application's view of the operating system.
Because Docker containers are lightweight, a single server or virtual machine can run several containers simultaneously. Docker can be integrated into various infrastructure tools, including OpenStack, Kubernetes and Oracle Container Cloud Service.
Security is a key concern for all enterprises. Oracle Ksplice updates select, critical components of Oracle Linux customers’ installations with all the important security patches, without any need to reboot.
To adapt the varying requirements of different IT systems, Ksplice can be used with online and offline clients and on the cloud.
OpenSCAP is an open source project that helps utilities implement the Security Content Automation Protocol (SCAP) - a set of standard security specifications for computer systems. OpenSCAP tools automate the auditing of your system based on a specific security policy. Oracle Linux includes key OpenSCAP packages.
The Linux Auditing System allows you to configure security rules and then record violations of these rules. Linux Auditing tracks user activity and system operations on your system. To reap the benefits of the Linux Auditing System, you should first learn how it fits into an overall approach to security and how to test rules for their impact on system performance.
