📊 Understanding VPS Resources: CPU, RAM, SSD, Bandwidth

Before purchasing a VPS, it's important to understand the resources you get and what they mean. CPU, RAM, SSD, bandwidth — all directly affect your server’s performance and the cost of the plan. In this article, we explain what each resource does and how to choose the right configuration for your needs. 🧠

🧮 CPU (Processor): How Many Cores Do You Need?

CPU means the central processing unit. On a VPS, these are virtual cores allocated from a physical CPU. More cores = more simultaneous tasks. Most websites only need 1–2 cores. For example:

• 🔹 1 core — blog, small CMS, static site;
• 🔹 2–4 cores — online store, API, CRM system;
• 🔹 6+ cores — streaming, rendering, gaming apps.

🧠 RAM (Memory)

RAM stores data your server is currently using. Low memory causes slowdowns and errors. Here’s a rough guide:

• 🔸 512–1024 MB — test sites, static pages;
• 🔸 2–4 GB — WordPress, OpenCart, small business projects;
• 🔸 8+ GB — databases, Node.js apps, heavy PHP projects.

💾 SSD Storage: Not Just Size

SSD ensures fast read/write speeds on a VPS. It’s not just about size — type matters too:

• 📀 SATA SSD — cheaper but slower;
• ⚡ NVMe SSD — ultra-fast, best for demanding tasks;
• 🗂 Backup storage — used for snapshots (usually slower, but larger in size).

📡 Bandwidth and Port Speed

Bandwidth is the amount of data transferred to/from your VPS. It may be limited (e.g. 1000 GB) or unlimited. Port speed (like 100 Mbps or 1 Gbps) affects how fast users can download or upload content.

🎯 Choosing a VPS Based on Resources

Don’t overpay for unused resources. It’s better to start with a basic plan and upgrade as your project grows. Ask if upgrades are possible without data loss — Bit.Hosting VPS can be upgraded in one click from the control panel. 🛠
