How to Choose East vs. West Coast Servers in the US?
Choosing between US East and West Coast server hosting locations represents a critical infrastructure decision that impacts application performance, user experience, and operational costs. This technical analysis examines the intricate factors of network topology, hardware specifications, and performance metrics that influence hosting decisions in these distinct geographical regions. Understanding these nuances is crucial for system architects and DevOps engineers tasked with infrastructure planning.
Server Infrastructure Landscape Overview
The East Coast’s server infrastructure, anchored by major facilities in Virginia (US-East-1), New York (NY4), and New Jersey (NJ2), features robust connections to European markets through dense submarine cable networks. Virginia’s data center alley, particularly in Ashburn, hosts approximately 70% of global internet traffic. Power grid reliability here maintains an impressive 99.999% uptime, supported by redundant power systems and sophisticated UPS configurations.
West Coast infrastructure centers in Los Angeles (LAX1), San Jose (SJC1), and Seattle (SEA1) leverage Pacific Rim connectivity through trans-Pacific cables. Silicon Valley’s concentration of tech companies has driven the development of cutting-edge cooling technologies and renewable energy integration, with facilities achieving Power Usage Effectiveness (PUE) ratings as low as 1.15. These facilities often implement advanced liquid cooling systems and AI-driven thermal management.
