Cloud-Specific Considerations
- Consider using general-purpose instances (D/M-series) for production
- Consider enabling auto-scaling for Large/Very Large deployments
Cloud Deployment Considerations
⚡ Performance Considerations
- Burstable vs General Purpose: B-series (Azure) and T-series (AWS) are burstable instances. For consistent high load, use D-series (Azure) or M-series (AWS).
- CPU Credits: Monitor credit balance on burstable instances to avoid throttling.
- Network Performance: Enable accelerated (Azure) or enhanced (AWS) networking where available.
💾 Storage Recommendations
- Use SSD storage: Consider SSD-based storage for faster performance.
- Backups: Enable automated backups or snapshots to protect your data.
- Scalability: Ensure your storage can grow with your usage.
🗄️ Managed Database Options
- Azure SQL Database: Starting at ~$150/month.
- Amazon RDS PostgreSQL: Starting at ~$50/month.
- Benefits: Automated backups, patching, high availability, and scalability.
- Trade-off: Higher cost compared to self-managed databases.
💡 Pro Tip: Start with burstable instances for development/testing, and upgrade to general-purpose instances for production workloads.
Server Software Requirements
Operating Systems
Windows Server:
- 2025 (including Server Core)
- 2022, 2019, 2016, 2012, 2008
Windows Desktop:
- Windows 11, 10, 8, 7
- Vista - Ultimate or Business
Database Options
- SQLite (default) - only recommended for smaller installations (1-50 users)
- PostgreSQL 9.0+ - Best performing
- MS SQL Server 2005+ - Express edition or better
- Azure SQL DB
💡 Tip: PostgreSQL provides a performance boost for Password Server.
Prerequisites
- .NET Framework 4.8 (auto-installed)
- IIS Express 10+ (included)
- IIS 7+ (optional)
Server Hardware Requirements
With the release of version 7, PPASS requires a 64-bit processor; use version 6 for 32-bit processors.
- Micro installation (<1k entries; 1-10 users):
- Dual-Core 1.6 Ghz or higher
- 2 GB RAM
- 500 MB free disk space
- Small installation (1k-10k entries; 10-100 users):
- Dual-Core 2 Ghz or higher
- 4 GB RAM
- 1 GB free disk space
- Medium installation (10k+ entries; 100-1,000 users):
- Quad-Core 2 Ghz or higher
- 8 GB RAM
- 2 GB free disk space
- Large installation (100k+ entries; 1,000-10,000 users):
- Contact Us for custom sizing
- Very Large installation (1M+ entries; 10,000+ users):
- Contact Us for enterprise architecture
Notes:
- Additional RAM is recommended as the database size grows, for optimal performance.
- Additional resources should be added when using MS-SQL, PostgreSQL, or Azure databases.
- For example, MS-SQL Standard itself requires 1 GB RAM and 6 GB free disk space
- Each database software has their own additional hardware requirements depending on installed components (please refer to vendor websites)
- The Server Requirements above already include database calculations with a default SQLite database.
Other Considerations
Virtualization Support
- ✓ VMware vSphere/ESXi - Full support including vMotion
- ✓ Microsoft Hyper-V - Including live migration
- ✓ Proxmox, KVM, Xen - Community tested
Security Best Practices
- Dedicated System: For maximum security, install on a dedicated system
- Access Control: Restrict server access to authorized administrators only
- Network Isolation: Consider placing on a separate VLAN
- Regular Updates: Keep OS and Password Server updated
Coexistence with Other Applications
Pleasant Password Server can run alongside other applications with sufficient resources. However, consider:
- Security implications of shared hosting
- Resource competition during peak usage
- Backup and maintenance window

Complexity: High - Enterprise support recommended
Performance Optimization
Database Performance
- MS SQL: Set max memory to 80% of available

- Database connections: 10 connections + 1 additional connection for every 10 users
- Enable IIS compression for remote users
When to Upgrade
- CPU consistently > 80%
- RAM usage > 90%
- Database locks occurring frequently
