Amazon API Gateway
Amazon API Gateway is a fully managed service from AWS that allows developers to create, publish, monitor and secure APIs (Application Programming Interfaces) at any scale. It acts as a “front door“ for applications to access backend services like Lambda functions, EC2 instances, or other web services.

Key features of Amazon API Gateway
Here are the features that make it a strategic asset in cloud-native and hybrid architectures.
REST & WebSocket support
Deploy both standard REST APIs and real-time WebSocket APIs. The API Gateway itself is a managed service, removing the need to manage its infrastructure or scaling.
Smart traffic management
Protect backend services using built-in request throttling and usage quotas to manage traffic flow and prevent overloads.
Secure by design
Control API access securely using integrated options like AWS Identity and Access Management (IAM), Amazon Cognito user pools, or custom Lambda authorizers.
Faster performance with optional caching
Leverage optional API caching within the service (regionally or via edge locations depending on endpoint type) to reduce latency and decrease load on your backend systems.
Built-in monitoring & tracing
Gain operational insights by tracking API usage, performance metrics (latency, error rates) and execution issues in near real-time with Amazon CloudWatch integration and AWS X-Ray tracing.
Versatile integration options
Connect APIs to various backend resources, including AWS Lambda functions, other AWS services (like DynamoDB, SQS, Step Functions), or any publicly accessible or private HTTP endpoint (e.g., via VPC Link).
Full API Lifecycle Management
Manage the complete lifecycle of your APIs, including deployment stages (like dev, test, prod), versioning support, canary release deployments for gradual rollouts and automatic client SDK generation.
Benefits of Amazon API Gateway
Here’s what your organisation gains by using API Gateway with the right design and implementation:
Launch faster, innovate quicker
Create new APIs and endpoints in minutes, no server provisioning or infrastructure setup required.
Less to manage, more to build
Say goodbye to managing servers, scaling and traffic handling. API Gateway handles the operational heavy lifting for you.
Strengthen your security
Enforce fine-grained access control, add custom authentication and benefit from built-in protection against DDoS attacks.
Boost performance, cut costs
Improve speed with caching and throttling and reduce expenses with optimized HTTP APIs designed for efficiency.
Ship APIs faster, with less friction
Auto-generate SDKs, import OpenAPI specs and iterate quickly, helping your teams deliver more with less effort.

Amazon API Gateway Pricing and Cost
Understand what influences your Amazon API Gateway pricing and operational costs
At Claria, as an AWS Advanced Consulting Partner, we help organisations plan, estimate and manage their Amazon API Gateway usage in alignment with their technical and operational goals.
Amazon API Gateway uses a pay-per-use pricing model, with costs determined by several factors specific to your API design and operation. Rather than following a traditional software licensing model.
Key factors influencing Amazon API Gateway Pricing and Cost
Several variables directly affect your Amazon API Gateway pricing:
API calls handled
Data transferred out of AWS
Connection minutes for WebSocket APIs
Optional caching capacity
Region-specific usage
The actual cost of running Amazon API Gateway depends on how your APIs are structured, consumed and scaled over time.
Even with transparent pricing, calculating the real operational cost requires analysing your API usage patterns and architectural choices. At Claria, we guide you in understanding how these factors influence your pricing, helping you make decisions that align with your budget, performance goals and future growth plans.
How Claria helps with Amazon API Gateway pricing
We work with you to:
Map your API use cases to the right API Gateway configuration
Estimate operational costs based on your expected API usage
Design an API Gateway setup that balances cost, performance and scalability
Monitor usage patterns to support financial planning and optimisation
Our approach ensures your API Gateway solution is configured for today’s needs and positioned for predictable, sustainable scaling as your platform grows.
For a project-specific pricing and cost strategy, contact Claria to discuss your API requirements.
When to use Amazon API Gateway
Amazon API Gateway is designed for organisations that need to expose, secure and manage APIs without the complexity of building or maintaining their own API infrastructure.
Here are common scenarios where Amazon API Gateway is the right choice:
You need to expose backend services securely and efficiently
API Gateway provides a managed entry point for microservices, databases and legacy systems, enabling controlled access for internal, partner or public consumers.
You’re building serverless or event-driven applications
API Gateway integrates with AWS Lambda and other services to support scalable, event-based architectures for web, mobile and IoT backends.
You want to centralise API security and governance
Enforce authentication, authorisation, throttling and quota policies in a unified layer to simplify management and protect backend systems.
You’re modernising legacy APIs
Migrate existing APIs into Amazon API Gateway to gain visibility, scalability and better control without rewriting backend logic.
You require multiple API protocols in one platform
Support REST, HTTP and WebSocket APIs within a single environment, choosing the right protocol for each use case.
You need to monetise or manage external API access
Implement usage plans, API keys and rate limiting to manage third-party consumption and enable tiered or paid API access.

Amazon API Gateways FAQs
Benefits:
Reduces latency by serving cached responses faster.
Decreases load on backend services.
Lowers operational costs by minimizing compute usage.
While both API Gateway and load balancers manage traffic routing, they serve different purposes:
Feature | Amazon API Gateway | Load Balancer (e.g., ALB) |
|---|---|---|
| Purpose | API management (REST, WebSocket, HTTP) | Distributes network traffic |
| Features | Request validation, throttling, caching, authorization, transformation | Path/host-based routing, health checks |
| Security | IAM, Lambda authorizers, OAuth/JWT | Security groups, WAF |
| Use Case | Public APIs, microservices | Load balancing web servers, containers |
Amazon API Gateway supports three types of APIs:
REST APIs: Ideal for CRUD operations and legacy systems. Feature-rich with support for transformations, caching and usage plans.
HTTP APIs: Lightweight and lower-cost alternative to REST APIs, best for simple proxy use cases and modern microservices.
WebSocket APIs: For two-way, real-time communication such as chat apps, gaming and streaming dashboards.
Amazon API Gateway provides multiple layers of security:
Authentication & Authorization:
IAM permissions
Lambda authorizers
Amazon Cognito user pools
JWT/OAuth 2.0 with HTTP APIs
Traffic Control:
Throttling and rate limiting
Usage plans with API keys
Network Security:
VPC integration
WAF (Web Application Firewall) integration
TLS encryption
Request Validation:
Input schema validation
Method request/response validation
HTTP APIs are lightweight, cost-effective and ideal for simple use cases. REST APIs offer advanced features like custom request/response transformations, AWS WAF support and flexible authorization options, making them better suited for complex applications.
API Gateway maps API routes to Lambda functions. It handles routing, formatting requests and responses and managing errors, freeing you from managing server infrastructure.
Yes, you can use Lambda authorizers for custom logic or Amazon Cognito for fully managed authentication and fine-grained access control.
API Gateway integrates with CloudWatch for metrics and logs and AWS X-Ray for tracing, helping you monitor API performance and set up alerts for proactive issue management.
Cache only idempotent responses, set appropriate TTL values and monitor cache usage through CloudWatch to optimize performance and efficiency.
