An API’s main purpose is to allow multiple applications to communicate with one another. This is made possible by the API’s functions allowing applications to access data and interact with external software components, operating systems, and microservices. While APIs are extremely useful tools on their own, they can present some security vulnerabilities. Of course, security vulnerabilities are a clear drawback whether working with enterprise APIs, mobile applications, or web applications. However, APIs can easily be made more secure and efficient through API gateways which provide a unified entry point across internal APIs. This unified entry point allows for greater control over user access and helps elevate API security measures like rate limiting while also applying security policies like OAuth or JWT. Plus, API gateways are extremely beneficial for securing microservices.

API gateways are API management tools that sit between a client and a collection of backend services. In most cases, “clients” are the apps making the actual API requests, and backend services can include AWS, databases, and web service providers. Because the API gateway sits between the client and backend services, it works to provide a single point of entry for developers to access an organization’s APIs.
An API gateway generally handles elements like:
In addition, API gateways act as a reverse proxy, working to:
API gateways sit between a user and a collection of microservices and provide three key services. These services include:
API gateways are components of an overall API management solution and offer a variety of benefits to the business and Ecommerce operations that implement them. Implementing API gateways creates an API design that allows for scalable services. In addition, many business operations follow a DevOps approach where developers use microservices to build and deploy apps quickly and efficiently. API gateways come in handy as APIs are one of the most commonly used microservices communication tools.
Additional benefits of implementing API gateways include:
Overall, API gateways have the potential to provide many key benefits to any organization. If you’re ready to discover how APIs can help elevate your business, DreamFactory is here to help.
