Introduction

API Gateways are software platforms that sit between users or applications and backend services. They act as a single entry point for APIs, handling tasks such as request routing, authentication, rate limiting, caching, monitoring, and traffic management. Instead of every microservice managing these functions separately, the gateway centralizes them for better control and consistency.

As businesses rely more on cloud applications, mobile apps, SaaS products, and distributed systems, API Gateways have become a core part of modern architecture. They help improve security, performance, and developer productivity while simplifying operations.

What Buyers Should Evaluate

• Performance and low latency
• Security controls
• Authentication support
• Scalability
• Deployment flexibility
• Monitoring and analytics
• Ease of management
