What Are The Prerequisites For Devops Training?

DevOps has quickly grown in popularity as more organizations embrace agile methods to promote faster, efficient and reliable software development processes. If you are entering the DevOps field, understanding its foundational requirements is vital - having these prerequisites helps grasp concepts faster, bridge skill gaps more quickly and ensure you are prepared to engage in real world DevOps environments more successfully.
This article will outline the necessary prerequisites for DevOps training, whether you are newcomer, experienced systems engineer or software developer wanting to switch gears. These prerequisites will prepare you for all of the complexities and rigors associated with DevOps.

## Prerequisites For Devops Training?
### 1. Understand Operating System
A fundamental knowledge of operating systems (OSs) is crucial for any DevOps engineer. Linux is commonly utilized, while other OSes such as Windows and MacOS may also play an integral part. Here is why OS knowledge is so essential -
- File Systems and Process Management - You should feel at home navigating file systems, managing processes and configuring system settings in DevOps environments. Tasks such as setting permissions, managing users and handling files may come up frequently in these environments.
- Scripting and Automation - Being proficient with Bash or PowerShell scripting will enable you to streamline processes, automate repetitive tasks and increase productivity.
- Recommendation - If you are new to Linux, start with beginner tutorials or virtual machines to practice navigating its environment. Building this foundation will make learning DevOps tools that rely on OS commands easier.

### 2. Understand Networking and Protocols
Understanding networking concepts is integral to DevOps as teams need to deploy applications securely across different environments efficiently. Being familiar with them will allow you to understand data flow, network security and service communications between services.
- Protocols - Familiarize yourself with protocols like HTTP, FTP, SSH and TCP/IP so you can effectively troubleshoot network issues and configure applications securely. Knowing these protocols allows for quicker troubleshooting processes as well as secure configuration of applications.
- Security - DevOps engineers should understand and implement effective network security practices for their applications, including managing firewall configurations, VPN connections and secure access points.
- Recommendation - Take basic networking courses or certifications that cover key protocols, subnetting techniques, IP addressing options and security best practices.

### 3. Programming or Scripting Knowledge
While DevOps roles do not typically require deep programming skills, having some familiarity with scripting languages like Python and Ruby is invaluable in writing automation scripts, customizing configurations and integrating various tools.
- Automation - Automation lies at the core of DevOps. Scripting allows you to automate deployments, monitoring and infrastructure management for efficient and error-free repetitive tasks.
- Coding APIs - DevOps often involves working with APIs. Learning how to read documentation about them and develop scripts for interaction can be invaluable.
- Recommendation - For beginners new to coding, Python is a beginner friendly and highly versatile programming language, which will enable you to automate tasks more quickly while understanding DevOps tools more readily.

### 4. Knowledge of Version Control Systems 
Version control systems like Git are essential in DevOps as a way of effectively tracking code changes and managing project history, as well as helping resolve any potential issues that arise during development or deployment. Knowing Git can provide collaboration opportunities, keep project history centralized and assist with issue resolution.
- Branching and Merging - To effectively manage feature development and bug fixes without disrupting the main codebase, branching strategies like Git Flow are indispensable. 
- Git is designed to facilitate collaboration among developers, streamlining workflows and reducing conflicts when merging code changes.
- Recommendation - Review Git tutorials and practice using its commands. Platforms like GitHub and GitLab offer additional features for collaboration as well as continuous integration/continuous delivery integration, essential for DevOps.

### 5. Proficiency with Continuous Integration/Continuous Deployment (CI/CD)
Continuous Integration and Deployment (CI/CD) is a DevOps practice to emphasize frequent code integration and continuous delivery of features. Tools like Jenkins, GitLab CI or CircleCI handle automated testing, building and deployment with ease.
- CI/CD Pipelines - Understanding pipeline concepts such as build, test and deploy stages is paramount to automating deployment processes quickly and releasing features quickly. These pipelines help teams deliver features without hassles.
- Monitoring and Feedback - CI/CD systems integrate with monitoring tools that provide feedback on deployments. Understanding these feedback loops enables faster issue resolution and more resilient releases.
- Recommendation - Begin your CI/CD pipeline experience with Jenkins to gain hands-on experience setting up basic deployment pipelines for code deployments.

## 6. Knowledge of Cloud Platforms
DevOps and cloud computing gives continuous deployment and integration capabilities within their environments. Being acquainted with at least one cloud platform such as Amazon Web Services (AWS), Azure or Google Cloud could prove immensely helpful for DevOps processes.
- Cloud Services - By understanding the fundamentals of cloud services - such as compute, storage and databases - it will allow you to establish environments which support DevOps practices.
- Containerization - Docker is widely utilized by DevOps teams for creating isolated environments for applications, improving portability across platforms.
- Recommendation - Start exploring fundamental cloud concepts with AWS's free tier, familiarizing yourself with setting up instances, storage and networking. Docker also offers beginner friendly resources to get you containerizing applications.

### 7. Infrastructure as Code (IaC)
DevOps engineers use Infrastructure as Code (IaC) to manage infrastructure using configuration files rather than manually configuring each component. Tools like Terraform, Ansible and AWS CloudFormation help teams define infrastructure in code with greater consistency and scalability.
- Automated Deployments - IaC makes automated deployments possible by providing reliable infrastructure provisioning across development, testing and production environments. At the same time, its tools help teams efficiently scale as necessary without needing manual intervention from IT administrators.
- Recommendation - Explore Terraform's documentation and tutorials for an introduction to IaC. Begin by creating simple configurations to automate cloud infrastructure setup.

### 8. Problem-Solving and Analytical Skills
DevOps requires more than technical knowledge - it also demands critical thinking and an ability to troubleshoot issues during deployments. Engineers in DevOps often encounter unexpected complications that require systematic solutions if issues arise, making problem solving an integral element of DevOps engineering.
- Troubleshooting - DevOps engineers focus on quickly recognizing and solving issues to minimize downtime.
- Optimization - DevOps engineers constantly look for ways to enhance deployment processes and system performance.
- Recommendation - Practice problem-solving by working on real-life scenarios or troubleshooting exercises. Building up your problem identification and resolution skills will serve you well in any DevOps role.
