• Centralised version control system.

• Used in legacy enterprise projects where Git might not be suitable.

⚙️ 2. Continuous Integration & Continuous Deployment (CI/CD) Tools

Jenkins

• Open-source automation server.

• Popular for CI/CD pipelines and integrating with a wide range of tools.

• Highly customisable with plugins.

GitLab CI/CD

• Built directly into GitLab.

• Supports complete pipeline management, from build to deploy.

CircleCI

• Cloud-based CI/CD tool.

• Known for speed and developer-friendly configuration.

Travis CI

• Easy-to-use tool for testing and deployment, particularly with GitHub projects.

🔄 3. Configuration Management Tools

These tools help you maintain and configure infrastructure in an automated way.

Ansible

• Agentless configuration management tool by Red Hat.

• Uses simple YAML syntax.

Puppet

• Manages server configurations using a declarative language.

• Suitable for large-scale infrastructure.

Chef

• Uses a Ruby-based DSL for configurations.

• Ideal for developers familiar with coding-based infrastructure.

4. Tools for Containerization

Applications and dependencies are packaged together by container tools, which facilitates deployment and portability.

• Docker
  the most widely used tool for containers.
• Enables the execution of applications in containers, which are isolated environments.
• Platform for Kubernetes Container Orchestration.
• aids in cluster-wide Docker container management and scaling.
• Podman is a lightweight Docker substitute that is lightweight.

Runs containers as a user and doesn’t need a daemon.

☁️ 5. Tools for Infrastructure as Code (IaC)

IaC tools use code to manage your infrastructure, which makes it scalable and reproducible.
