When asking “where should I host my server,” pulling out a spec comparison sheet first is the wrong order. What you need to decide first is what you are going to deploy, and depending on that, about half the time you don’t need to buy a server at all.
What to Decide First: What to Deploy and Where
Static Sites (HTML, CSS, JS, blogs, portfolios, SPA frontends)
→ No VPS needed. Free hosting like Cloudflare Pages, Vercel, Netlify, and GitHub Pages is better. They include CDN, HTTPS, and automatic deployment, with no server to manage.
API Servers (No DB, sporadic requests)
→ Free or low-cost tiers of Serverless or PaaS are advantageous. You don’t pay when there are no requests. However, there is a cold start latency if left unused for a while.
API + Database, must remain online 24/7
→ This is where you need a VPS. If you need constant uptime, data persistence, background tasks, or cron jobs, a VPS is the simplest and cheapest option.
Multiple containers, background workers, lots of custom installations
→ VPS. Aim for slightly higher specs.
In short, the two deciding questions are: “Does it need to be constantly running?” and “Does it need to store state?” If the answer to both is no, do not buy a server.
Criteria for Comparison
If you have decided to buy a VPS, here are six things to look at, ordered by importance.
1. Region (Server Location) — If your target audience is in Korea, this matters more than specs. Physical distance translates directly into latency. A domestic region offers single-digit to tens of milliseconds, Japan and Singapore take tens of milliseconds, and the US West Coast easily exceeds 100ms. On screens that make multiple API calls, this difference multiplies and becomes highly noticeable.
2. RAM — This is the first resource to run out in side projects. The most common failure pattern by far is the process dying because memory runs out while vCPU remains idle.
3. Traffic Policy — Monthly bandwidth limits and overage charges. If you serve a lot of images or files, this is where your bill can spike.
4. Backups — Whether snapshots are free or paid. Even if they cost money, turn them on. Losing your server is only a matter of time.
5. Management Console and Documentation — If you are a beginner, the quality of documentation is more important than specs. Services with plenty of search results when you get stuck will ultimately save you time.
6. Billing Method — Hourly billing makes it easy to experiment and delete, while monthly flat-rate pre-payment makes costs predictable.
How to Choose
Instead of ranking providers, we categorize them by characteristics. Since pricing and specs change frequently, this classification remains valid longer.
| Category | Characteristics | Target Audience |
|---|---|---|
| Major Global Clouds | Has the most regions and services, with extensive documentation. However, the pricing structure is complex, and your bill can easily spike if you are not careful. | Those who plan to scale later or need to align with company infrastructure. |
| Developer-Friendly VPS | Flat-rate pricing, simple consoles, and great tutorials. The default choice for side projects. | Most people using a VPS for the first time. |
| Budget European/US VPS | Generous specs for the price, but physically far from Korea. | Batch jobs, crawlers, or personal tools that are not latency-sensitive. |
| Domestic Clouds | Domestic regions, Korean language support, and local payment methods. | Services targeting Korean users, or corporate entities. |
If your service targets Korean users, it is practical to prioritize domestic or Japanese regions. Budget overseas VPS options look attractive on spec sheets, but if latency leads to user churn, the losses will outweigh the savings.
Workflow to Your First Deployment
Once you create an instance, the workflow is as follows:
- Connect via SSH Key — It is best to disable password login from the start. Brute-force attempts will begin within minutes of creating the server.
- Firewall — Open only ports 22 (SSH), 80, and 443, and close the rest. Leaving database ports open to the public is the most common security mishap.
- Create a Non-Root User Account — Avoid working as root for daily operations.
- Deploy the Application — Using Docker makes environment replication much easier.
- Connect a Domain — Point the A record to your server’s IP.
- HTTPS — Issue a certificate via Let’s Encrypt and verify automatic renewal.
- Configure Automatic Restart — Ensure your app starts automatically even if the server reboots.
This is the bare minimum configuration. If you have the capacity, add automatic backups and disk usage alerts. Running out of disk space and crashing the service is the most common failure in novice VPS administration.
When You Should NOT Buy a VPS
- You have no time to manage it. With a VPS, security updates, certificate renewals, log rotation, and disk management are entirely your responsibility. An abandoned server will likely be found compromised a few months later.
- Your traffic is extremely irregular. If traffic is close to zero most of the time but spikes occasionally, serverless is better for both cost and scaling.
- It is a static site. As mentioned earlier, free hosting is faster and more secure.
⚠️ Pricing, specs, and region availability vary by provider and change frequently. This article covers the selection criteria; please check the official pricing pages of each provider for actual costs.
Frequently Asked Questions
What are the minimum specs I need?
While static sites or very lightweight APIs can run on 1 vCPU and 1 GB of RAM, it is safer to start with at least 2 GB if you are hosting a database on the same server. Since running builds on the server often fails due to out-of-memory errors, we recommend building locally or in a CI environment and only deploying the build artifacts to the server.
Is it better to use a domestic or overseas provider?
If your users are in Korea, domestic or Japanese regions are advantageous due to latency. Conversely, for personal tools, crawlers, or batch jobs where response speed is not critical, budget overseas VPS options offer more generous specs for the same price. If you need payment convenience and Korean language support, domestic providers are more convenient.
Do I need to know how to manage a server?
For a VPS, yes, you need to know. If you don’t, it is better to start with a Platform-as-a-Service (PaaS). You only need to deploy, and the service handles server management. You can migrate to a VPS later when costs or limitations prompt you to. Many people fail to finish their projects because they try to learn server administration from day one.
