DevOps is a software development method that emphasizes collaboration and communication between software developers and IT professionals. The goal of DevOps is to build, test, and release software faster and more reliably. The prerequisites for DevOps are

Linux Basics

Here are some key areas that you might want to consider as prerequisites for learning about Linux in the context of DevOps:

Shell scripting: Many tasks in DevOps can be automated using shell scripts, so being familiar with shell scripting languages such as Bash is important. You should understand concepts such as variables, loops, and control structures.

Package management: In Linux, the software is often distributed as packages and managed using package managers.

File permissions: In Linux, file access is controlled using permissions and ownership. You should understand how these concepts work and are able to use commands to manage permissions.

Networking Basics

Here are some key networking concepts and skills that can be useful as prerequisites for learning about networking in the context of DevOps:

Networking fundamentals: You should be familiar with basic networking concepts such as IP addresses, subnets, and protocols such as TCP and UDP.

Network configuration: You should be familiar with how to configure network settings on various operating systems, including Linux and Windows. This might include setting up static IP addresses, configuring DNS settings, and working with network interfaces.

Virtual private networks (VPNs): Understanding how VPNs work and how to set them up can be useful in a DevOps context, especially when working with cloud environments.

Network security: Understanding how to secure networks and protect against common threats such as malware and hacking is important for any DevOps professional.

Application Basics

Here are some key application development concepts and skills that can be useful as prerequisites for learning about application development in the context of DevOps:

Programming languages: Familiarity with at least one programming language is often helpful for a DevOps professional. Popular choices include Python, Java, and Ruby.

Web development: Understanding web development concepts such as HTML, CSS, and JavaScript can be useful for working with web-based applications.

Application architecture: Familiarity with common application architectures, such as client-server and microservices, can help to understand how applications are built and how they can be deployed and managed in a DevOps context.

Databases: Understanding how to work with databases, including concepts such as schemas and SQL, can be useful for managing applications that store data.

Source Control Management (SCM)

Here are some key source control management (SCM) concepts and skills that can be useful as prerequisites for learning about SCM in the context of DevOps:

Version control systems: Familiarity with version control systems such as Git is essential for any DevOps professional. You should be comfortable with concepts such as branching, merging, and working with remote repositories.

Git commands: Knowing how to use basic Git commands that are important for working with Git repositories.

Git branching: Understanding how to create and work with branches in Git is important for managing code changes and collaborating with others.

Git merging: Knowing how to merge branches in Git is essential for integrating code changes and resolving conflicts.

Git workflow: Familiarity with common Git workflows, such as feature branching and Gitflow, can be helpful for organizing and managing code changes.

Web Server Concepts

Here are some key web server concepts and skills that can be useful as prerequisites for learning about web servers in the context of DevOps:

Web server types: Familiarity with different types of web servers, such as Apache and Nginx, is important for understanding how web servers work and how they can be configured and managed.

Web server configuration: Knowing how to configure web servers, including setting up virtual hosts and SSL certificates, is essential for deploying and managing web applications.

Reverse proxies: Understanding how reverse proxies work and how to configure them can be useful for load balancing and improving the performance of web applications.

Here are some key security concepts and skills that can be useful as prerequisites for learning about security in the context of DevOps:

Network security: Understanding how to secure networks and protect against common threats such as malware and hacking is important for any DevOps professional.

Application security: Familiarity with best practices for secure application development, such as input validation and secure coding practices, is essential for building and deploying secure applications.

Encryption: Familiarity with encryption technologies and techniques, such as SSL/TLS and public key infrastructure (PKI), can be useful for securing data in transit and at rest.
