– and combining the results.

What is API gateway and how it works?
An API gateway is a way to decouple the client interface from your backend implementation. When a client makes a request, the API gateway breaks it into multiple requests, routes them to the right places, produces a response, and keeps track of everything.
Which API Gateway is best for Microservices?
Why NGINX Plus Is the Best API Gateway for Both Traditional Apps and MicroservicesNGINX and NGINX Plus are already the industry’s most pervasive API gateway. … NGINX is also the pioneer in developing microservices reference architectures.More items…•
Are Google APIs free?
Some Google APIs charge for usage, and you need to enable billing before you can start using these APIs. Some APIs allow free usage up to a courtesy usage limit, and in some cases this free limit is increased when you enable billing. … For some APIs, more services are available after you enable billing.
When should I use AWS API gateway?
API Gateway provides WebSocket API management functionality such as the following:Monitoring and throttling of connections and messages.Using AWS X-Ray to trace messages as they travel through the APIs to backend services.Easy integration with HTTP/HTTPS endpoints.
Why do we use API gateway?
An API gateway provides a single, unified API entry point across one or more internal APIs. They typically layer rate limiting and security as well. … An API gateway can help provide a unified entry point for external consumers, independent of the number and composition of internal microservices.
How does API gateway scale?
By default, API Gateway allows for up to 10,000 requests per second. … If you receive a large burst of traffic, both API Gateway and Lambda will scale in response to the traffic. However, relational databases typically have limited memory/cpu capacity and will quickly exhaust the total number of connections.

Is a Microservice an API?
The Difference Between APIs and Microservices An API is a contract that provides guidance for a consumer to use the underlying service. A microservice is an architectural design that separates portions of a (usually monolithic) application into small, self-containing services.
How do I protect my AWS API gateway?
Use a random HTTP header value in CloudFront origin configuration and use an API Gateway request model validation to verify it instead of API keys alone. Combine Lambda@Edge and an API Gateway custom authorizer to sign and verify incoming requests using a shared secret known only to the two.
How does AWS API gateway work?
Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. APIs act as the “front door” for applications to access data, business logic, or functionality from your backend services.
Does API gateway do load balancing?
Load Balancing: The API Gateway can work as a load balancer to handle requests in the most efficient manner. It can keep a track of the request load it has sent to different nodes of a particular service. … An API Gateway can record the basic response time from each node of a service instance.
Is Lambda cheaper than ec2?
Summary. Keep these two points in mind: For most periodic or very light workloads, Lambda is dramatically less expensive than even the smallest EC2 instances. Focus on the memory and execution time that a typical transaction in your app will need to relate a given instance size to the break-even Lambda cost.
Is AWS API gateway highly available?
