Ultimate Web Hosting Glossary 2025

Web Hosting Terminology Explained

Shared hosting is a budget-friendly web hosting solution where multiple websites share resources on a single physical server. As of 2025, this remains the most popular entry-level option featuring:
• Resource pooling (CPU/RAM/bandwidth)
• Pre-installed control panels (cPanel/Plesk)
• Standardized LAMP/LEMP stacks
• Managed security updates
Pricing typically ranges $1.99-$9.99/month, making it ideal for personal blogs and small business sites with <10,000 monthly visitors. [/fusion_toggle][fusion_toggle title="Cloud vs VPS Hosting Differences" open="no"] Key technical distinctions in 2025: 1. Architecture: VPS uses localized virtualization (KVM/OpenVZ) while cloud employs distributed containerization (Kubernetes/Docker) 2. Scaling: VPS requires manual upgrades vs cloud's auto-scaling APIs 3. Redundancy: Cloud offers multi-zone failover vs VPS single-point failure risk 4. Billing: VPS fixed pricing vs cloud pay-per-usage models Performance benchmarks show cloud solutions handle traffic spikes 40% more efficiently than traditional VPS. [/fusion_toggle][fusion_toggle title="How CDN Acceleration Works" open="no"] Modern CDN networks (2025 edition) utilize: 1. Edge Computing: Process requests at 3000+ global PoPs 2. AI Routing: Machine learning optimizes path selection 3. Instant Purge: <1sec cache invalidation via GraphQL APIs 4. WebP 2.0: Next-gen image compression (30% smaller than AVIF) Leading providers now deliver 95% cache hit rates with sub-50ms TTFB across continents, critical for Core Web Vitals compliance. [/fusion_toggle][fusion_toggle title="Enterprise RAID Configurations" open="no"] 2025 Server Storage Standards: • RAID 50: Combines RAID 5 parity with RAID 0 striping (6+ drives) • RAID 60: Dual parity protection for mission-critical data (8+ drives) • NVMe RAID: PCIe 5.0 arrays achieving 14GB/s throughput • Self-Healing: Predictive disk replacement via SMART analytics Current benchmarks show RAID 60 configurations can sustain simultaneous 3-disk failures with zero downtime during rebuilds. [/fusion_toggle][fusion_toggle title="SSL Certificate Types Compared" open="no"] 2025 Encryption Standards: 1. DV SSL: Automated validation (5min issuance) 2. OV SSL: Business verification + 256-bit encryption 3. EV SSL: Extended validation with legal guarantees 4. Post-Quantum SSL: Quantum-resistant algorithms (coming 2026) All modern browsers now enforce HTTPS by default, with Chrome 125+ blocking mixed content entirely. Google's 2025 algorithm update prioritizes sites using OV/EV certificates. [/fusion_toggle][/fusion_accordion][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container] ```
