A beginner path through cloud and DevOps concepts

Your starting point

Use a tiny local service or an existing app. These projects teach deployment ideas without assuming paid infrastructure, a new account, or an installed container runtime.

• Run and stop a local program.
• Understand a configuration value, a JSON response, and a project folder.

Your finish line

You can distinguish application code from configuration, explain different health signals, identify the exact running artifact, and rehearse recovery while preserving separate sample data.

Stack up four small wins

1. STEP 1 OF 4

   Map the runtime contract

   List what a small service needs to start, what it returns, and where any writable sample data belongs. Name one action that will prove it works.

   Bro tip: Draw three boxes for code, configuration names, and sample data. Place each runtime requirement in its box without recording credential values.

   What you’ll learn

   • Code, configuration, and persistent state.
   • Loopback-only local services.
   • A concrete user-journey smoke check.
   You’re ready to move on when

   The list separates source code, configuration names, and sample-data paths without exposing credential values.

2. STEP 2 OF 4

   Make configuration observable

   Build the configurable local status service and try valid and invalid setup.

   Bro tip: Change just the service label, restart, and compare the response. Keep the previous value nearby so the change is easy to spot.

   What you’ll learn

   • Documented defaults.
   • Startup validation.
   • Version and status responses.
   You’re ready to move on when

   A changed label appears after restart and invalid configuration causes a clear startup failure.

3. STEP 3 OF 4

   Model health and recovery

   Build the health-check lab and follow a controlled outage from unavailable to recovered.

   Bro tip: Keep the state table beside the monitor output. Follow one simulated outage through the failed normal request and the recovery.

   What you’ll learn

   • Startup, readiness, and liveness.
   • Temporary dependency failure.
   • Recorded state transitions.
   You’re ready to move on when

   Check results match the expected state table and do not hide the failed normal operation.

4. STEP 4 OF 4

   Rehearse a release

   Package two local versions, detect a controlled failed release, and return to the earlier artifact.

   Bro tip: Record the selected artifact before each smoke check. After recovery, repeat the sample action and inspect the separate sample data.

   What you’ll learn

   • Versioned artifacts and digests.
   • Smoke checks.
   • Application rollback and separate data.
   You’re ready to move on when

   The earlier version's real sample action works again and the separate sample data remains available.

Your build lineup

1. Build a configurable local status service

   Learn environment configuration and startup validation without opening a cloud account.

2. Create a local health-check lab

   Simulate startup, readiness, and dependency failures and see what each check means.

3. Rehearse a local release and rollback

   Package two harmless versions, identify the active artifact, and practise recovery locally.

Watch it. Then build it.

Start with a worked example, then connect the recording to your own small, checkable build. Videos open on their creator’s or publisher’s website.

   What is DevOps? | One Dev Question

   Microsoft · Abel Wang

   A short conceptual introduction to the relationship between development, operations, and software delivery.

   For step 1: Map the runtime contract

   Before watching: No cloud account or prior DevOps experience is needed to watch. Knowing what an application is will help.

   Watch, then try

   Use the delivery overview to name who builds, runs, and checks your tiny local service. Write down one visible behavior that will prove your app still works after a change.

   This is an orientation, not a deployment walkthrough. Its Azure links are optional further exploration; the path's configuration, health, and rollback projects stay on your computer and do not require buying cloud services.

   Docker Containers and Kubernetes Fundamentals – Full Hands-On Course

   freeCodeCamp.org · Guy Barrette

   Explains containers, persistent data, application settings, local Kubernetes, and startup, readiness, and liveness probes.

   For step 3: Model health and recovery

   Before watching: Be able to run a small local app and use basic terminal commands. Following the demos needs a compatible container runtime; Kubernetes demos require a local Kubernetes setup.

   Watch, then try

   Start with containers and persistence, then find the application-settings and probe sections. Compare a process that is running with a service that can complete its normal operation during a controlled dependency failure.

   Optional extension after the plain local health-check lab. Concentrate on the local demonstrations; image publishing and registry accounts are optional. The existing path projects need no paid infrastructure, container runtime, or cloud account. Older tool screens may differ from your installed tools.
