Study by subject
Cloud and DevOps
In cloud and DevOps you learn service models, equivalent services across the big providers, Docker, kubectl and git commands, and the stages of CI/CD by heart. Lumi asks them back until the commands come on their own.
How to turn this subject into cards
Make one card per service with its role in one sentence and its equivalent at the three big providers, AWS, Azure and Google Cloud. For commands, one card per command with what it does and a use case. The stages of a CI/CD pipeline go in order, one card per stage. The trap is following a tutorial by copying commands without ever finding them again from memory. With Lumi you write the command before seeing the answer, and that recall is what fixes it (Roediger and Karpicke, 2006). Go over them in short, spaced sessions rather than in one block the night before (Cepeda et al., 2006).
What you need to know by heart
- IaaS, PaaS and SaaS, and who manages what in each model.
- Equivalent services at AWS, Azure and Google Cloud, compute, storage, networking, databases.
- The most common Docker and kubectl commands and what they do.
- Everyday git commands, commit, branch, merge, rebase.
- The stages of a CI/CD pipeline, from commit to deployment, with Computer science for the basics.
How Lumi helps you remember it
You teach your cards to Lumi, service models, equivalent services, commands, pipelines. It forgets over time, like you do, then quizzes you right before you would forget. As the certification or the interview approaches, the Mist settles over what you know less well and Lumi asks that first. You arrive typing the commands from memory.
Example cards
Three cards the way you would write them, with the answer Lumi expects.
What is the difference between IaaS and SaaS?
IaaS rents infrastructure, SaaS delivers a ready to use application.
Which kubectl command lists pods?
kubectl get pods
What is a CI/CD pipeline for?
To test and deploy code automatically with every change.

Cloud and DevOps · teach this card to Lumi
The IaaS model rents infrastructure such as virtual machines and networking. A Docker container packages an application with its dependencies. Kubernetes orchestrates containers across a cluster. The git commit command records a snapshot of your changes in the history.

Frequently asked questions
- How do I remember equivalent services between providers?
- One card per need, for example object storage, with the name at each provider. Lumi asks the three names together, which links them.
- Do flashcards replace practice on a cloud account?
- They complement it. You practise to understand, then write the commands and ideas on cards, and Lumi keeps them available in your memory.
- Should I mix Docker, git and Kubernetes in my sessions?
- Yes, mixing topics helps you pick the right command at the right moment. Lumi shuffles your cards for you (Rohrer and Taylor, 2007).
