OJS Hosting Requirements: What Your Server Needs Before You Install OJS

You're Ready to Launch Your Journal. But What Hosting Do You Actually Need?

You have decided to launch your journal on OJS. You start looking at hosting providers. One offers shared hosting for $5 per month. Another recommends a VPS for $20 per month. A third suggests dedicated servers at $200+ per month. You are confused about what you actually need.

The wrong hosting choice costs you in two ways: too little hosting and your journal is slow or crashes under load. Too much hosting and you are paying for capacity you never use. Understanding OJS's actual hosting requirements helps you make the right choice, balancing cost, performance, and reliability.

This guide explains OJS's hosting requirements, compares hosting types, and helps you choose the right hosting for your journal's size and budget, written by OJS specialists who have deployed OJS on hosting ranging from budget shared plans to enterprise dedicated servers.

Minimum Server Requirements for OJS

Before considering hosting types, understand OJS's baseline requirements.

CPU Requirements:

OJS is not CPU-intensive. A single modern CPU core can handle moderate journal traffic.

Minimum: 1 CPU core
Typical: 1-2 CPU cores
High-traffic: 2-4 CPU cores

Most shared hosting and entry-level VPS have sufficient CPU.

RAM Requirements:

RAM is more critical than CPU. OJS needs memory for:

• PHP processing
• Database queries
• Concurrent user sessions

Minimum: 512 MB RAM
Recommended: 1-2 GB RAM
High-traffic: 4+ GB RAM

Underpowered RAM causes slow page loads and timeout errors.

Storage Requirements:

Storage needs depend on article volume and file sizes.

Base OJS installation: 100-200 MB
Per article (with PDF): 2-5 MB
Per issue metadata: < 1 MB

Example calculations:
- 50 articles: ~250 MB
- 500 articles: ~2.5 GB
- 5,000 articles: ~25 GB

Add space for backups (1x your total data size minimum).

Database:

OJS requires MySQL 5.7+ or PostgreSQL 9.5+. Most hosting provides this.

PHP Version:

OJS 3.3+ requires PHP 7.3+. OJS 3.4+ requires PHP 8.0+.

Most modern hosting provides compatible PHP versions.

Bandwidth:

Bandwidth is rarely a constraint unless you have very high traffic.

Typical journal: 50-500 GB/month
High-traffic journal: 500-2,000 GB/month

Most hosting plans include sufficient bandwidth. If bandwidth is capped, upgrade or switch providers.

Hosting Type Comparison

Option 1: Shared Hosting

What it is: Your website shares a server with 100+ other websites. Resources are divided among users.

Cost: $5-30 per month

Pros:

• Cheapest option
• Easy setup (cPanel control panel)
• No server administration needed
• Tech support included

Cons:

• Limited control (cannot install custom software)
• Shared resources (other sites' traffic affects your journal)
• Limited to small journals (under 1,000 articles typical)
• Cannot customize server settings
• Performance varies based on other users

Best for:

• Brand new journals testing OJS
• Journals with under 100 articles
• Very tight budgets
• Editors with no technical skills

Performance: Adequate for small journals. Slow for medium-sized journals.

Recommendation: Start here if budget is limited. Plan to upgrade to VPS as journal grows.

Option 2: Virtual Private Server (VPS)

What it is: A virtual machine on a shared physical server. You have dedicated resources (RAM, CPU, storage) but share the physical server with other VPS customers.

Cost: $15-60 per month

Pros:

• Dedicated resources (your performance isn't affected by other users)
• Full control (install software, customize settings)
• Scalable (upgrade RAM/CPU easily)
• Good performance at reasonable cost
• Linux or Windows options
• Root access for customization

Cons:

• Requires technical knowledge or hosting support contract
• More setup required (you configure everything)
• Need to manage updates and security
• More expensive than shared hosting

Best for:

• Growing journals (1,000-10,000 articles)
• Medium-traffic journals
• Editors with some technical skills or IT support
• Long-term journal operations

Performance: Good. Consistent performance regardless of other users.

Recommendation: Upgrade to VPS when shared hosting feels slow. Most journals operate well on VPS.

Option 3: Dedicated Server

What it is: A physical server dedicated entirely to your journal. You have all resources.

Cost: $100-500+ per month

Pros:

• Maximum performance
• Complete control
• No shared resources
• Can handle very high traffic
• Custom hardware configuration
• Enterprise-grade reliability

Cons:

• Most expensive option
• Requires significant technical expertise
• Full responsibility for security and updates
• Overkill for most journals

Best for:

• Very large journals (100,000+ articles)
• Extremely high-traffic journals
• Organizations with IT staff
• Multi-journal hosting

Performance: Excellent. Unlimited dedicated resources.

Recommendation: Only necessary for large, well-funded journals. Most journals do not need dedicated servers.

Hosting Comparison Matrix

Sizing Your Hosting Based on Journal Growth

Stage 1: Launch (Years 1-2)

Expected articles: 20-100
Expected monthly traffic: 1,000-10,000 visits

→ Recommendation: Shared Hosting or Entry-Level VPS

• Budget option: Shared hosting ($5-15/mo)
• Better option: VPS ($15-25/mo)

Stage 2: Growth (Years 2-5)

Expected articles: 100-1,000
Expected monthly traffic: 10,000-100,000 visits

→ Recommendation: VPS

• Entry-level VPS ($15-25/mo) may be sufficient
• Mid-range VPS ($30-50/mo) recommended
• Upgrade from shared hosting if you started there

Stage 3: Maturity (Years 5+)

Expected articles: 1,000-10,000+
Expected monthly traffic: 100,000+ visits

→ Recommendation: VPS or Dedicated Server

• High-performance VPS ($50-100+/mo)
• Or dedicated server ($100+/mo)
• Consider dedicated if adding second journal

Red Flags in Hosting Providers

Avoid hosting providers that:

❌ Don't support the PHP version you need (OJS requires PHP 7.3+)
❌ Don't provide MySQL 5.7+ or PostgreSQL 9.5+
❌ Limit disk space to under 10 GB
❌ Limit bandwidth severely (under 100 GB/month)
❌ Don't provide SSH/terminal access on VPS
❌ Don't offer backups or charge excessive backup fees
❌ Have poor customer support or long response times
❌ Frequently go down or have reliability issues
❌ Don't support cron jobs (needed for OJS scheduled tasks)
❌ Prohibit content management systems

These limitations will cause problems running OJS.

Evaluating Your Current Hosting

Already have hosting? Determine if it can run OJS.

Check these details:

PHP Version:

• Log into cPanel
• Go to Software → Select PHP Version
• Confirm PHP 7.3 or higher

Database:

• Confirm MySQL 5.7+ or PostgreSQL 9.5+ is available
• Most hosting provides this

Disk Space:

• Check your hosting dashboard
• Confirm you have at least 2-5 GB available
• Plan for growth

SSH/Terminal Access:

• For VPS: confirm you have SSH access
• For shared hosting: nice-to-have but not required

Cron Jobs:

• Ask your hosting provider if cron jobs are supported
• OJS uses cron for email and scheduled tasks

If you cannot confirm these, ask your hosting provider or switch to one that supports OJS.

Migration Path: Growing Out of Shared Hosting

As your journal grows, you may need to upgrade hosting.

Signs you should upgrade from shared to VPS:

• Pages are loading slowly (over 3 seconds)
• Journal becomes unresponsive during peak traffic
• Hosting provider asks you to upgrade
• You are approaching your resource limits
• You want more control over server configuration
• You plan to add second journal

Migration process:

1. Purchase VPS hosting
2. Install OJS on new VPS
3. Back up your entire journal from shared hosting
4. Migrate data to new VPS (see migration guide)
5. Update domain DNS to point to new VPS
6. Test thoroughly
7. Keep old hosting active as backup for 2 weeks
8. Cancel old hosting

Typical migration takes 1-2 days.

Cost vs Performance Analysis

Budget-conscious journal:

• Shared hosting: $10/mo = $120/year
• Simple, cheap, works for launch
• Upgrade to VPS ($30/mo) after 2-3 years

Growth-focused journal:

• VPS: $30/mo = $360/year
• Better performance from day one
• Easier to grow without migration
• Worth the extra cost for medium-sized journals

Enterprise journal:

• Dedicated server: $200/mo = $2,400/year
• Maximum performance and control
• Overkill for most journals

Most journals are best served by VPS, it balances cost, performance, and control.
