DevOps and Infrastructure as Code Basics
DevOps and Infrastructure as Code (IaC) basics involve integrating software development and IT operations to streamline workflows, increase deployment speed, and improve collaboration. DevOps emphasizes automation, continuous integration, and continuous delivery, while IaC uses code to manage and provision infrastructure, ensuring consistency and scalability. Together, they enable teams to automate infrastructure setup, reduce manual errors, and efficiently manage resources, leading to more reliable and agile software delivery processes.

💡 Key Takeaways
- Understand the core goal of DevOps: faster, reliable software delivery through collaboration between development and operations.
- Recognize how automation, continuous integration (CI), and continuous delivery (CD) streamline workflows and minimize manual errors.
- Grasp Infrastructure as Code (IaC): provisioning and managing infrastructure using code for repeatability and version control.
- Identify common DevOps and IaC tools (e.g., Terraform, Ansible, Docker, Kubernetes) and the role each plays in the pipeline.
❓ Frequently Asked Questions
What is DevOps?
DevOps is a set of practices that blends software development and IT operations to shorten delivery cycles, improve collaboration, and automate tasks such as building, testing, and deploying software.
What is Infrastructure as Code (IaC)?
IaC is the practice of managing and provisioning infrastructure through machine-readable configuration files or code, enabling repeatable, versioned, and auditable environments.
How do DevOps and IaC work together?
IaC automates the provisioning and configuration of infrastructure used in DevOps workflows, enabling consistent environments and faster, more reliable deployments.
What are common tools used in IaC and DevOps?
IaC tools include Terraform, AWS CloudFormation, Ansible, Puppet, Chef, and Pulumi; CI/CD and automation tools include Jenkins, GitHub Actions, and GitLab CI.
What is Continuous Integration and Continuous Delivery (CI/CD)?
CI automatically builds and tests code when changes are made; CD automatically deploys validated changes to staging or production, enabling faster and safer releases.
