Dev Ops Course Cheat sheet: Building a Strong Foundation
I am writing these blogs because I recently completed a comprehensive DevOps course where I gained in-depth knowledge of the topics mentioned. As I progressed through the course, I realized the importance of having a concise and accessible resource to revise and reinforce my understanding of each topic. Therefore, I decided to create cheat sheets in the form of blog posts. These cheat sheets will not only serve as a handy reference for myself but also benefit others who are also interested in mastering DevOps concepts. By documenting each topic and providing concise explanations, I aim to create a valuable resource that simplifies complex concepts and facilitates hands-on practice. This way, I can solidify my understanding while helping others on their DevOps journey.
Linux Fundamentals: Linux is the backbone of many DevOps practices. To effectively manage servers, deploy applications, and work with command-line tools, a solid understanding of Linux fundamentals is crucial. Dive into topics such as Linux history, file system hierarchy, basic commands for file manipulation, user management, and file permissions.
Git and GitHub Fundamentals: Version control is a vital aspect of DevOps, and Git is the go-to tool for source code management. Learn about Git's three-stage architecture, repository management, branching strategies, and essential commands like commit, push, pull, revert, and reset. Discover how to collaborate effectively with team members using platforms like GitHub.
AWS Fundamentals: Amazon Web Services (AWS) is a leading cloud platform widely used in DevOps workflows. Gain an understanding of AWS's global infrastructure and explore key services like Elastic Compute Cloud (EC2), Virtual Private Cloud (VPC), Simple Storage Service (S3), Identity and Access Management (IAM), Relational Database Service (RDS), and more. Learn how to leverage cloud services for scalability, resilience, and efficiency.
Linux for DevOps: Deepen your Linux knowledge specifically tailored for DevOps practices. Explore advanced commands, shell scripting, process management, and system administration techniques. Gain insights into monitoring, troubleshooting, and optimizing Linux-based infrastructure.
Source Code Management with Git: Dive deeper into Git's advanced features and workflows. Learn about branching strategies, resolving conflicts, working with remote repositories, and collaborating effectively with team members. Understand Git's role in supporting continuous integration and continuous delivery (CI/CD) pipelines.
Continuous Integration/Continuous Deployment (CI/CD) with Jenkins: Jenkins is a popular open-source automation tool for building and deploying software. Discover the history and evolution of CI/CD, and learn how Jenkins fits into the DevOps landscape. Install and configure Jenkins, create pipelines, integrate with source control, trigger builds, and automate the testing and deployment process.
Containerization with Docker: Containerization revolutionizes application deployment and management. Delve into Docker's architecture, understand the benefits of containerization, and explore Docker commands for building, running, and managing containers. Learn about Docker images, container orchestration, and integrating Docker with CI/CD pipelines.
Cloud Services: Expand your cloud expertise beyond AWS. Explore other cloud providers like Microsoft Azure and Google Cloud Platform (GCP). Understand their core services, deployment models, and integration with DevOps practices. Compare and contrast different cloud platforms to make informed decisions for your projects.
Infrastructure as Code with Terraform: Infrastructure as Code (IaC) enables the automated provisioning and management of infrastructure resources. Dive into Terraform, a popular IaC tool, and learn how to define and provision infrastructure using declarative configuration files. Explore variables, resources, dependencies, and modules to manage infrastructure as code.
Configuration Management with Ansible: Configuration management ensures consistency and reproducibility in your infrastructure and application environments. Explore Ansible, a powerful configuration management tool. Learn how to write Ansible playbooks to automate the provisioning, configuration, and management of servers and applications. Discover advanced Ansible features like roles, variables, conditionals, and modules.
Container Orchestration with Kubernetes: Kubernetes (K8s) is the leading container orchestration platform. Dive into Kubernetes architecture, understand its features, and learn how to deploy, scale, and manage containerized applications. Explore concepts like pods, services, deployments, namespaces, and ingress. Discover how Kubernetes supports high availability, load balancing, and self-healing.
Monitoring and Observability: Monitoring and observability are crucial for maintaining application health and performance. Set up monitoring systems like Prometheus and Grafana to collect metrics, visualize data, and gain insights into your infrastructure. Explore log management tools, centralized logging, and real-time analysis techniques.
