Infrastructure Ops Overview

Why infrastructure matters for feature flagging and experimentation

Feature flagging and experimentation platforms require robust infrastructure to deliver consistent, low-latency responses that don't impact an application's performance. Statsig must process every feature gate evaluation, experiment assignment, and analytics event reliably to ensure:

• Consistent user experiences: Users always receive the same feature variant throughout their session.
• Real-time decision making: Feature flags evaluate in milliseconds to avoid blocking your application.
• Accurate experiment results: Statsig must capture and process every user interaction to generate reliable statistical insights.
• Business continuity: Infrastructure downtime can't block feature releases or compromise running experiments.

Enterprise-grade scale and reliability

Statsig processes massive volumes of data while maintaining enterprise-grade reliability standards:

Key metrics

• 2+ Trillion events processed per day
• Over 3 Billion unique monthly experiment subjects
• 99.99% infrastructure uptime for API and Console

Scalable architecture

Statsig's infrastructure has been proven at scale by companies including OpenAI, Atlassian, Microsoft, Notion, Flipkart, and other enterprises. All customers get access to enterprise-grade infrastructure from day one.

Statsig can scale with you regardless of volume, so there is no reason to switch tools or migrate to a different solution as you grow. Investment in scaled infrastructure also allows Statsig to offer affordable pricing across all products and customer tiers.

Infrastructure covers more than serving configs and logging events. Statsig also provides comprehensive infrastructure management including:

• Real-time health checks and monitoring
• Automated guardrails on feature rollouts and releases
• Multi-region deployment for global availability
• Built-in redundancy and failover capabilities

Getting started

This section includes documentation about infrastructure setup and operations for your team when using Statsig. By default, Statsig works without additional setup. Some instructions here apply to specific use cases with special requirements.
