Welcome to the DevOps Bootcamp series! This series of blog posts will guide you step-by-step, starting from the basics of DevOps and gradually advancing to hands-on skills, tools, and best practices. If you're new to DevOps, this bootcamp is the perfect place to start!
To make learning accessible, I’ll be sharing practical examples and demonstrations in my DevOps Bootcamp videos in Bangla , while writing this blog series in English to reach a broader audience. Let’s get started with the fundamentals of DevOps and set the stage for your DevOps journey!
Bootcamp Overview
In this bootcamp, we’ll start from scratch and cover each area essential to building a strong DevOps foundation. From containers and automation to continuous integration and cloud infrastructure, each blog post will build on the last, ensuring you’re prepared for the next level. DevOps is a journey of continuous learning, so take each topic step-by-step and enjoy the process!
Start your journey here: DevOps Roadmap
1. Containers & Container Orchestration
Containers form the backbone of modern DevOps workflows by providing consistency across environments. They make applications portable and reliable, no matter where they're deployed. Mastering containerization and orchestration is essential for any DevOps professional.
Core Topics:
- Docker: Learn the basics of Docker, including images, containers, Dockerfiles, and networking.
- Kubernetes: Dive into Kubernetes fundamentals, from pods and deployments to scaling and managing clusters.
Hands-On Practice:
- Set up Docker and create your first container.
- Build and deploy a simple application in Kubernetes using tools like Minikube.
2. Infrastructure as Code (IaC) & Configuration Management
IaC allows you to manage infrastructure using code, making your environment repeatable and version-controlled. Configuration management tools then ensure systems remain consistent across deployments.
Core Topics:
- Terraform: Provision cloud resources using Terraform, covering concepts like providers, resources, and modules.
- Ansible: Automate configuration and application deployment with Ansible playbooks and roles.
Hands-On Practice:
- Use Terraform to set up a virtual machine on AWS.
- Automate a configuration task on a remote server with Ansible.
3. Monitoring and Observability
Monitoring and observability help ensure your systems are performing as expected. Learn how to set up tools to monitor infrastructure and gain visibility into applications, crucial for quick troubleshooting.
Core Tools:
- Prometheus and Grafana: Set up monitoring and visualization.
- ELK Stack (Elasticsearch, Logstash, Kibana): For logging and log analysis.
Hands-On Practice:
- Configure Prometheus to collect metrics from your infrastructure.
- Set up a Grafana dashboard to visualize server health.
4. Mastering a Cloud Provider
To excel in DevOps, it's crucial to understand at least one cloud provider, as most modern systems are cloud-based. Each provider offers unique tools and services that are essential to DevOps.
Popular Cloud Platforms:
- AWS: The market leader, holding 32% of the global cloud share, offers a comprehensive suite of services such as EC2, S3, and VPC. It’s known for scalability, reliability, and innovation.
- Azure: Capturing 23% of the market, Azure excels in enterprise solutions and hybrid cloud deployments, seamlessly integrating with Microsoft products.
- Google Cloud: Holding 11% of the market, Google Cloud Platform (GCP), launched in 2008 as App Engine, provides IaaS, PaaS, and SaaS solutions. It is renowned for its data and AI/ML services, powering products like YouTube and Google Search. GCP operates across 34 regions, 103 zones, and over 200 edge locations.
Understanding the strengths and unique offerings of each platform helps DevOps professionals design efficient, scalable, and reliable cloud solutions.
Hands-On Practice:
- Deploy a virtual machine, configure networking, and experiment with cloud storage.
5. Linux Fundamentals & Scripting
Linux is foundational for DevOps. You'll need a solid understanding of basic Linux commands and scripting to automate tasks and manage servers.
Core Topics:
- Linux Essentials: Command-line basics, file systems, and permissions.
- Shell Scripting: Write scripts to automate tasks like backups and deployments.
Module 1: Introduction to DevOps
Module Overview
In this first module, we’ll introduce DevOps by covering its definition, evolution, core principles, and the importance of DevOps culture. By the end of this module, you'll understand the goals of DevOps and why it’s essential for modern software delivery.
What is DevOps?
DevOps combines cultural philosophies, practices, and tools to unify development (Dev) and IT operations (Ops), fostering collaboration to speed up delivery and improve software quality. In simple terms, DevOps breaks down silos between developers and operations teams, enabling faster, more efficient product releases.

Evolution and Core Principles of DevOps
DevOps emerged to address key challenges in traditional development, like fragmented teams and long release cycles. Today, core principles like Continuous Integration (CI), Continuous Delivery (CD), Infrastructure as Code (IaC), and automation drive DevOps success.
Notable Success Stories:
- Netflix: Embraced microservices and continuous delivery.
- Amazon: Pioneered a “you build it, you run it” culture.
Module Objectives and Benefits
Objectives:
- Automate and streamline the software delivery pipeline.
- Improve team collaboration.
- Enable quick, reliable releases.
Benefits:
- Faster time-to-market.
- Greater software stability.
- Reduced time to resolve issues.
The Role of Culture in DevOps
A successful DevOps implementation relies on a culture that values collaboration and continuous improvement. Building this culture fosters cross-functional teamwork and accelerates innovation.
Key Elements:
- Open Communication: Encourage dialogue across teams.
- Continuous Feedback: Establish feedback loops to improve process and product.
This is just the beginning of the DevOps Bootcamp series! In future posts, we’ll delve deeper into specific tools, practices, and skills you’ll need to succeed in DevOps. Stay tuned for Part 2, where we’ll dive into essential Linux skills for DevOps beginners, covering fundamental commands, file system navigation, text editing, process management, networking, and package management.
Remember, DevOps is a journey, not a destination. Keep learning, practicing, and expanding your skills as we move forward in this bootcamp!
