Understanding VPS Resources

RAM (Memory)

RAM is the most important factor for VPS performance. It determines how many concurrent visitors, processes, and database queries your server can handle.

  • 2 GB: Ideal for 1–2 small WordPress sites, a single Node.js app, or a development environment.
  • 4 GB: Great for 3–5 WordPress sites, a moderate-traffic web app, or a small e-commerce store.
  • 8 GB+: Suited for high-traffic sites, multiple applications, database-heavy workloads, or Docker containers.

CPU Cores

CPU handles computational tasks: PHP processing, image resizing, encryption, and running background jobs.

  • 2 cores: Sufficient for most small to medium websites and applications with moderate traffic.
  • 4 cores: Recommended for WooCommerce stores, media-heavy sites, and applications with background processing.
  • 6+ cores: Needed for video transcoding, machine learning, game servers, or high-throughput APIs.

Storage (SSD)

Storage is where your files, databases, and backups live. All of Interserver's VPS plans use enterprise-grade SSD storage for fast read/write speeds.

  • 50 GB: Plenty for several WordPress sites, a small app, or a personal project repository.
  • 100 GB: Good for media-heavy sites, multiple applications, or storing database backups.
  • 200 GB+: Needed for large e-commerce catalogs, extensive media libraries, or data-driven applications.

Bandwidth

Bandwidth determines how much data can be transferred to and from your server each month. Interserver's plans include generous allocations starting at 1 TB.

Don't Forget: You Can Scale Up

One of the best things about Interserver VPS is that you can upgrade at any time with zero downtime. Starting with the $6 Starter plan and upgrading later is a smart strategy — you only pay for what you need, and the Price Lock Guarantee ensures your new rate stays locked.

Quick Decision Framework

Still unsure? Ask yourself these questions:

  1. How many monthly visitors? Under 10K → Starter. 10K–50K → Professional. 50K+ → Enterprise.
  2. Are you running databases? MySQL, PostgreSQL, or MongoDB benefit from more RAM. 4 GB is a safe starting point.
  3. Do you need managed support? Interserver offers both managed and unmanaged. If you're not comfortable with server admin, choose managed.
  4. Is budget a concern? The Price Lock Guarantee makes Interserver the most predictable option long-term. Start small and upgrade as you grow.

Still have questions? Start with the $6 Starter plan — it's backed by a 30-day guarantee.
