DevOps Tools You Must Know in 2025
Whether you’re a Software Developer, System Engineer, or complete beginner, this DevOps Roadmap will provide all the necessary details to kickstart and land your first job in DevOps.
Programming Language
Learning the programming language provides the foundation knowledge for software development and later writing automation scripts for DevOps Roadmap.
You can choose any one language, Python or Golang.
I recommend learning Python for DevOps roadmap if you’re learning programming for the first time.
Python is an easy-to-learn language. It follows an English-like syntax. It is easy to write and beginner-friendly. Major frameworks and libraries are available, which simplify complex tasks and speed up the process.
Knowledge Check:
- Variables & Data Types.
- Conditional statements and Loops.
- Data structure – Array, List, and Dictionaries.
- Error handling.
- Basic input and output
Version Control
When you start learning a programming language, you might have made multiple changes to make it work.
GIT is a source code management tool that tracks the changes and manages the source code, enabling teams to collaborate.
GitHub and GitLab are major platforms that provide the GIT as a service.
Knowledge Check:
- Cloning projects
- Creating branch, switching branch
- Committing your changes, pushing to remote
- Creating a pull request
- Merging the code
Operating System & Linux
As a DevOps Engineer, your primary responsibilities are provisioning and managing the servers.
Linux is the most used OS for servers, it’s essential to be comfortable with the Linux and Command Line Interface (CLI)
The best way to familiarize yourself with Linux and CLI is to use Linux as your go-to development environment.
Key things to learn are Bash Script, File Systems, File Management and Permission, and a basic idea of Virtualization.
Knowledge Check:
- Hands-on practice with Ubuntu or Fedora.
- Navigating directory, and filesystem.
- Create, rename, and delete file/directory.
- Check and update the permission.
- Running command as the root user.
Networking, Security & Protocols
Networking is essential for transferring data across the internet.
Security for safeguarding and protecting the data while in transit. We’ve Firewalls and a scanner for this.
Protocols are rules that standardize communication so that all network devices can understand defining the guidelines for the format of data, timing, or error-checking methods to ensure both receiving and transmitting devices can understand.
OSI model explains the process of transferring data from software, operating systems, and network devices.
Knowledge Check:
- OSI Model and Layers
- How DNS works?
- SSH and Firewall
- SSL/TLS
- FTP/SFTP
- HTTP/HTTPS
- Request lifecycle, different methods GET, POST

Server Management
This part focuses on setting up and managing the real server.
You might think what is a Server?
The server is a dedicated computer that handles various tasks 24/7. The task can be running applications and databases in the context of the DevOps roadmap.
There are various types of servers:
- Web Servers are for hosting a website.
- Proxy servers to act as firewalls or caching.
- Content-heavy sites like Instagram need a caching Server and CDN
- Load balancers to manage the load across multiple servers.
Knowledge Check:
- Install and set up Apache & Nginx servers.
- Reverse Proxy vs Forward Proxy
- Set up Nginx as a reverse proxy.
- What is caching, TTL, and expiry?
- How does Load Balancer work?
- What is CDN? Akamai or Cloudflare.
Containerization
Containerization has become the de-facto standard for modern software development.
Packaging, deployment, and execution of the application with dependencies, keeping it a small and lightweight unit called a container.
Docker is a widely used technology for creating and managing containers but it’s not the only option.

Knowledge Check:
- Docker images.
- Running containers.
- Networking in containers.
- Persistent storage volume.
- Docker Compose to run multiple containers together.
- Write your own Dockerfile, build, and run the container.
Container Orchestration: Kubernetes
Enterprises and companies run hundreds and thousands of containers in the production environment, emphasizing the critical need for effective container management.
Kubernetes is a powerful container orchestration tool that streamlined the management of containerized applications with consistent deployment, automated operations, and resource utilization at scale.
Learning the Kubernetes can advance your career in the DevOps roadmap.
Knowledge Check:
- How does Kubernetes work?
- Core concepts, Pods, Deployment, Service, Nodes & ReplicaSets
- Write your YAML configuration to deploy the application with Kubernetes.
- Try to do hands-on horizontal scaling.
- Persistent storage with Kubernetes Volume.
Infrastructure as Code (IaC)
Manual work tends to have errors, and replicating the whole infrastructure with consistent configuration is challenging.
Infrastructure as Code (IaC) is a method that manages and provides the infrastructure as machine-readable code files.
The main idea behind IaC is to write down the whole infrastructure as code, promote version control, track all the changes, and roll back to the previous state.
There are two main concepts here.
- Infrastructure management.
- Configuration management.
Terraform, OpenTofu, and Ansible are the most popular tools along the DevOps roadmap.
While Terraform manages the resources, Ansible manages the configuration and application deployment. Integrating these two provides a robust IaC workflow

Knowledge Check:
- Writing Terraform files.
- Terraform plan and apply.
- Explore the various providers in Terraform.
- Terraform state management.
- Writing Ansible playbook.
- YAML syntax.
- Managing the inventory.
Popular DevOps Tools for CI/CD Pipelines
Continuous Integration and Continuous Delivery (CI/CD) is the automated process of frequently building, testing, and deploying code.
It provides a dynamic and reliable software release pipeline by detecting bugs and improving overall code quality.
CI stands for Continuous Integration, includes:
- Continuous Integration. ( Automated builds )
- Continuous Testing. ( Automated test case runs )
CD stands for Continuous Delivery, includes:
- Continuous Delivery. ( Automated release to repository )
- Continuous Deployment. ( Automated deployment to production )
Jenkins is the crucial CI/CD technology that automates the entire software delivery process.
Learning the CI/CD is a must for the DevOps roadmap.
Knowledge Check:
- Settings up Jenkins server and pipeline.
- Build tools.
- Package management tools.
- Generating software artifacts.
- Explore GitHub Actions.
Monitoring & Observability
Once the application is running on production, Monitoring the performance and tracking the metrics is critical.
It helps track down any underlying issues in the running application and the infrastructure.
You must learn Prometheus and Grafana for the DevOps roadmap to master the metrics export and dashboard creation.
Another important part is collecting the application logs, aggregating, and indexing to search and identify issues.
The most popular tools are ELK stack, Elastic Search, Loagstash, and Kibana.
Knowledge Check:
- Set up the Prometheus and various exporters.
- Check the visualization of metrics in Grafana.
- Collecting the logs with Logstash.
- Aggregating and indexing in Elastic Search.
- Checking the logs in Kibana.
- Set up some alerts in Grafana and Kibana.
