DevOps, Cloud & Infrastructure

Graphic illustrating serverless computing for beginners: developers upload functions to managed cloud, events trigger automatic scaling, no server maintenance, pay-per-use billing.

IaC diagram: teams write version-controlled config to provision and manage infrastructure automatically, enabling consistent, repeatable, and scalable deployments across environments.

Diagram showing steps to build a CI/CD pipeline with GitHub Actions: code commit, automated tests, container build, workflow YAML deployment to cloud, monitoring and feedback loop.

Three cloud platforms - AWS, Azure, Google Cloud - shown as logos on podium steps; a learner weighing skills, job demand, ecosystem and cost to decide which cloud to study in 2025.

Step-by-step Terraform workflow: plan, versioned configs, apply changes, provision cloud resources, automate pipelines, monitor state and collaborate on infrastructure as code IaC.

Kubernetes diagram: Pods run containers, Deployments manage replicas and rollouts, Services provide stable virtual IP and load balancing so pods are reachable by clients plus DNS.

Docker basics for developers and sysadmins: containers, images, Dockerfile, CLI, port mapping, volumes, networking, orchestration, CI/CD, deployment and collaborative workflows now

Step-by-step Jenkins setup: install Jenkins, configure agents and credentials, link Git, add build triggers, define pipeline jobs, run automated builds and view console output now.

Split infographic: left — Continuous Integration: developers merge code into repo with automated tests; right — Continuous Deployment: pipeline delivers changes to production fast.
