We have summarized the structures, screens, and priorities that often get in the way when first applying serverless, small VM, or high-performance VM and when to use them for non-majors. We have organized key standards, common mistakes, inspection points, and next actions in one place so that you can directly attach them to the actual planning and execution flow, so apply them right away.
Quick answer
You should choose between serverless, a small VM, and a high-performance VM based on usage patterns and operating needs, not on which option sounds more powerful.
What this guide answers right away
- When serverless is a good fit and when it is not
- What kinds of services can stay simple on a small VM
- How to recognize workloads that need a larger VM
- What non-developers should check first before choosing infrastructure
Key takeaways
- Serverless often works well when traffic is irregular.
- A small VM can be enough for simple services that must stay on.
- Heavy real-time processing, memory usage, or background jobs may require a larger VM.
- The right choice depends on current usage patterns, not on prestige.
Practical criteria
- Write down when users arrive and how often requests happen.
- Check whether there are background jobs or long-running tasks.
- Consider whether the operator can actually manage the complexity.
- At the start, choosing the simplest explainable structure is usually safer than choosing the biggest machine.
When should you use serverless, small VM, or high-performance VM? is the main topic of this guide. If you are applying When should you use serverless, small VM, or high-performance VM? in a real project, start with the structure and checks below.
This article is an article that organizes when to use serverless, small VM, and high-performance VM based on the points that often get stuck when adding them to actual work flow.
It is safer to check the current environment and official documents before actual application.
In cost-centered project planning, topics such as when to use serverless, small VM, and high-performance VM become more important than whether the operating costs can be sustained rather than whether the code runs. It is easy for non-majors to overlook this part especially when creating services with AI, and one small decision can lead to a difference in the amount of money lost each month. The fact that infrastructure selection must vary depending on the service structure
Why this topic is important
The reason this topic is important is not simply knowing the theory. The most common mistake is thinking that something just needs to be a feature. However, if you postpone the cost structure to a later date, the cost of tokens, servers, storage, and external APIs will increase at the same time, making the structure more disadvantageous as the service grows. In particular, if you look at this topic late, it may seem good at first, but the further you go, the more difficult it becomes to judge, and the cost of revision also increases.
Points often missed by beginners
The points that beginners often miss are quite similar. Infrastructure suitable for the initial MVP / Method suitable for services with irregular requests / If there is a lot of background work, the same items will most likely pop up late in the middle of the work unless separately written down. Then, the standards initially set are shaken, and the same explanation is often repeated or the structure is reversed.
It becomes much easier if you organize it like this
When dealing with this topic, just writing down ‘things that need to be decided right away’ and ‘things that can be added later’ will make the overall flow much more stable.
In fact, it will be much easier to organize if you check it like below. This list is not intended to be a professional document, but should be thought of as a minimum standard to avoid missing during an actual project.
- Infrastructure suitable for initial MVP
- A method suitable for services with uneven requests
- When there is a lot of background work
- First determine the scope that non-majors can manage
Ultimately, the important criteria
Ultimately, the important thing is not to relegate this topic to a separate issue. Whether it’s planning, promotion, operations, or maintenance, if you set a standard early on, you’ll be much less likely to repeat the same problems later. If you have a service you’re working on today, just writing this topic down as a checklist can make the next decision much easier.
In the next article, it would be natural to summarize File storage, log storage, and image storage are all costs.
Practice check questions
The following questions are sufficient to check immediately after reading this article.
- In my current project, what items have already been set for this topic and what items are still empty?
- In this version, did you distinguish between what needs to be decided now and what can be postponed until later?
- Have you left this standard in a document or checklist so that it can be viewed repeatedly in the next task?
One more thing to check
Understanding this topic goes a long way when connecting it to actual workflows rather than just memorizing definitions. If you write down in one line when this concept appears in a service you are currently creating or already operating, and who should make what judgment when a problem arises, it will become a much more practical standard. If you accumulate these notes, you can respond much faster when you encounter a similar situation again.
As an easy example,
For example, a lightly called API might be a good fit for serverless, or a simple admin app that needs to be always on might suffice with a small VM. Conversely, tasks that require a lot of real-time processing and large memory usage may require larger VMs. In the end, usage comes first.
Quick checklist for When should you use serverless, small VM, or high-performance VM?
Use this checklist before you apply When should you use serverless, small VM, or high-performance VM? in an actual post or product flow.
- Is the first action obvious as soon as the user lands on the page?
- Are intermediate steps simple enough that buttons and explanations do not overlap?
- Does the result naturally lead to a next action instead of a dead end?
- Could you explain the structure again later without adding unnecessary screens?

- File storage, log storage, and image storage all cost money.
Things to verify before you apply it
- Tool UI and function configuration may vary depending on the time, so it is safer to check again based on the current version.
- Stateful features like external APIs, authentication, and payments can have a much larger structural impact in a real project than in a small example.
