Welcome to the ultimate DevOps roadmap! Whether you’re a beginner or aiming for the next level, this blog will take you from the fundamentals to advanced concepts with real-world examples and hands-on tips. Imagine streamlining your workflows, deploying apps in seconds, and automating everything in between—sounds exciting, right? 🌟

In this guide, we’ll explore the tools and technologies that power the world of DevOps—from mastering Linux basics to containerizing apps with Docker and scaling them with Kubernetes. You'll get your hands dirty with version control in Git, learn the magic of CI/CD pipelines, and even dive into cloud platforms like AWS and Azure.

This isn’t just theory—get ready to transform your skills and kickstart your DevOps journey today! Let’s dive in! 🚀

Level 1 - DevOps Pre-Requisites🌱

To get started in DevOps, it’s crucial to build a solid foundation. Here's what you should know:

OS & Linux Fundamentals

  • Shell commands⌨️

  • Shell Scripting📜

  • File Permissions🔒

  • SSH Key Management🔑

  • Networking🌐

  • Virtualization🖥️

Version Control - Git, GitHub, GitLab📁

Git allows you to track changes, collaborate with teams & manage codebases effectively.

  • Common Commands

  • Branching Strategies

  • Merging

  • Resolving Conflicts

Build Tools & Package Manager🛠️

Dependencies - External libraries/modules our software relies on to function

  • Install dependencies

  • Execute tests

  • Package application(jar, zip, etc..)

Level 2 - DevOps Fundamentals⚙️

As you get more comfortable, it's time to dive into the core tools and technologies.

Containerization - Docker🐳

Containers are standardized units, that encapsulate everything the software needs to run inside(app dependencies, configuration, etc..)

It has many benefits:

  • Isolation: Processes in one container don’t interfere with those in another.

  • Consistency: Ensures that the application runs consistently across different environments.

  • Scalability: Easy to scale applications horizontally.

Artifact Repository📦

  • Stored

  • Locked

  • Organized

Central Storage System for managing & versioning various types of build artifacts generated during the software development process.

For Docker, we have specific registries for storing only Docker images.(DockerHub)

Cloud Basics - Cloud Infrastructure☁️

Think of it as renting space and services on someone else’s powerful computer, that you can access anytime, anywhere

  • Compute - Virtual Machines

  • Storage

  • Networking - firewall, etc..

Level 3 - DevOps Core⚡

Now that you've mastered the fundamentals, it’s time to level up.

Let's explore the heart of DevOps tools that power modern software development and operations.

Container Orchestration - Kubernetes🚢

  • Kubernetes is the most popular container orchestration platform.

  • Orchestration tools automate the deployment, scaling, and management of containerized applications.

  • Makes sure apps run smoothly and reliably.

  • K8s turns all the nodes(servers) in a cluster into one powerful virtual machine.

  • You don’t need to worry about where your app runs in the cluster. K8s distributes workloads across the available hardware.

  • Self-Healing: K8s restarts, reschedules, or recreates failed containers automatically.

  • Fault Tolerance: K8s immediately shifts workloads to other nodes if a node fails.

  • Scale your app up or down easily by changing the number of replicas.

Advanced Cloud Platform - AWS, Azure, GCP, …🌍

You should know:

  • Design, build, and maintain complex cloud infrastructure

  • Scale cloud infrastructure

  • Deploy and manage clusters

  • Networking services

  • Compute services

  • Storage services

  • Access Management

Managed Kubernetes service - EKS, AKS, GKE

Kubernetes as a Service:

It makes it easier for developers and organizations to harness the power of Kubernetes without being burdened by its operational challenges,

Continuous Integration/Continuous Delivery(CI/CD) - Jenkins, GitLab CI, GitHub Actions

  • Setting up the CI/CD server

  • Integrate code repository to trigger pipeline

  • Build a streamlined workflow to build and deploy apps.

Level 4 - DevOps Advanced

Now, it’s time to hone your skills and dive into advanced DevOps practices.

Infrastructure As Code(IAC) - Terraform, Pulumi📄

Programming Language - Python🐍

  • Most used language

  • Easy to learn(Easy Syntax)

  • Can be used for many different use cases

  • Large ecosystem

Configuration Management - Ansible

Monitoring & Observability - Prometheus, Grafana📊

Add-On

Security🔐

  • Learn the best security practices for each technology.

  • BONUS: Learn DevSecOps tools to automate security checks.

Wrapping Up: Your DevOps Journey Awaits! 🚀

And there you have it, folks! You've now got the perfect roadmap to launch your DevOps career. From mastering OS fundamentals to diving deep into Kubernetes and cloud platforms, you're well-equipped to tackle any challenge that comes your way. 🌟

Remember, DevOps is all about collaboration, automation, and continuous improvement. So, don’t be afraid to experiment, learn, and iterate as you go. And while the journey might seem long, each step you take brings you closer to becoming a DevOps wizard! 🔮

Now, it’s time to roll up your sleeves, grab your favorite tool (and maybe some coffee ☕), and start applying these skills. Whether you're building scalable cloud infrastructures or automating CI/CD pipelines, the world of DevOps is waiting for you to make an impact.

Stay curious, keep building, and never stop automating! 💡

Catch you in the next chapter of your DevOps adventure! ✨
