Secure APIs with API Gateway

Secure APIs with API Gateway

NETSOL in partnership with AWS brings decades of transformation, modernization, migration and analytics experience combined with highly skilled AWS resources.

Amazon API Gateway

APIs are a major element in laying the foundation for reusable integration endpoints. Amazon API Gateway is important to achieve modern architecture deployment towards digital transformation. NETSOL Technologies Americas, Inc. (NTA). can secure your APIs at any scale by implementing multi-layered security for each API, enabling you to easily handle massive request volumes.

API Gateway manages a myriad of tasks related to accepting and processing hundreds of thousands of simultaneous API calls. This includes throttling, API version management, traffic management, authorization and access control, and CORS support. NTA. can help design or migrate legacy applications to a scalable and cost-effective serverless architecture.

API Types


HTTP APIs enable you to build RESTful APIs with lower latency and lower cost as compared to REST APIs. HTTP APIs are the ideal choice for building APIs that only require API proxy functionality

Restful APIs

REST APIs and HTTP APIs are both products of RESTful API. REST APIs support more features than HTTP APIs, while HTTP APIs are designed with the least features so that they can be offered at a lower price

Application Integration

A WebSocket API in API Gateway is an amalgamation of WebSocket routes that are integrated with backend HTTP endpoints, Lambda functions, or other AWS services.

Features of Amazon API Gateway


API Gateway provides various tools to authorize access to APIs and control service operation access.


API Gateway helps in managing traffic with throttling so that backend processes can withstand traffic surges.

Operations Monitoring

After an API is published and in use, API Gateway offers a metrics dashboard to track calls made to services.

Lifecycle Management

With API Gateway you can run multiple versions of the same API simultaneously so that applications can continue to call previous API versions even after the latest versions are published.

Benefits of API Gateway

Low Costs

With Amazon API Gateway you pay only for the calls made to APIs and data transfer out


API Gateway provides end-users with the lowest possible latency for API requests and responses with Amazon CloudFront integration.

Serverless Architecture

When combined with Lambda, Amazon API Gateway allows to create completely serverless APIs.

Easy Monitoring

After API is deployed, Amazon API Gateway provides a dashboard to visually monitor calls to services using Amazon CloudWatch, where one can see performance metrics and information on API calls, data latency, and error rates.

Efficient API

Amazon API Gateway allows to simultaneously run multiple versions of the same API, allowing you to quickly iterate, test, and release new versions.

Flexible Security

API Gateway can also help in validation of incoming requests by running a Lambda authorizer on Lambda AWS. You can authorize access to your APIs with AWS Identity and Access Management (IAM) and Amazon Cognito.

Our Work

Segregating Public and Private API endpoints using API Gateway

The company had a few API’s running in the cloud and after getting acquired by a parent organization, it wanted to limit the access to those APIs across each department. The company required to expose defined private endpoints to other parts of the departments privately while keeping the subset of APIs public. NTA. were able to achieve the required functionality using Serverless architecture mainly using API Gateway REST Regional and Private endpoints with resource-based policies. This helped the company drive operational safety, efficiency, and maintain business continuity.

Enabling access of Private API endpoints to internal users over Direct Connect

Company had few API’s running in the AWS environment and required those API’s to be accessible to the customers over the internet and from their internal network securely using Direct Connect Network. Client wanted NTA to use Serverless Architecture to achieve the required functionality. NTA developed a solution mainly using API Gateway REST Regional, Private endpoints with resource-based policies and Direct Connect to fulfill the requirements. This helped the company to operate safely, and in a streamline manner.
