• Ideal for organizations needing scale and reliability without owning the facility.
• Common value adds: remote hands, cross-connects, and managed interconnection.
• Flexible growth: add racks and power density as demand increases.

Hyperscale Data Centers

These are the cloud giants—AWS, Microsoft Azure, Google Cloud—operating facilities with 10,000+ servers and 40+ megawatts of power capacity per site (often far more). They emphasize automation, custom hardware, and advanced cooling to sustain elastic scaling and cost efficiency.

• Software-defined infrastructure allocates compute, storage, and networking on demand.
• Custom silicon and high-bandwidth interconnects for AI/ML and analytics.
• Global footprints minimize latency and support regional compliance.

Edge Data Centers

Small, distributed facilities placed close to users or data sources—cell towers, retail sites, campuses—to serve latency-sensitive workloads (AR/VR, autonomous systems, industrial IoT).

• Typical footprint: 50–500 sq. ft. with 5–50 racks.
• Targets <10 ms latency for real-time responsiveness.
• Market outlook (consensus across analysts): strong double-digit CAGR through 2030+ as 5G and AI at the edge scale.
