Thanks to all who attended the first episode in the Webinar Shorts series on the API Facade pattern. The first episode is an overview of the idea. Facade patterns are simple interfaces to complex systems. This e-book examines the API Facade design pattern – what it is, why it’s important, and best. The goal of an API Facade Pattern is to articulate those internal systems and make them useful and consumable by app developers. This e-book examines the .

Beyond that it becomes “Where is it easiest and most efficient to do a task? This approach also makes the client code much more complex.

You also want to set spike arrests to keep your API traffic from overwhelming your target server. So you should be fine just delivering the API in raw cacade there, however you’ll still need to: Once you know the App is allowed to access your API there are some simple security policies that should be run on the Apigee layer. Sometimes, however, there are dependencies between requests.

From Design to Deployment. For example, Amazon describes how hundreds of services are involved in rendering their product page.

In contrast, when using the microservices architecture the data displayed on the product details page is owned by multiple microservices. Using an API Gateway.

Hystrix times out calls that exceed the specified threshold. Otherwise, developers will be forced to wait in line in order to update the gateway. Make sure you strip out unnecessary response headers cookies, server versions, etc that aren’t relevant to the API Contract. Number of items in the shopping cart Order history Customer reviews Low inventory warning Shipping options Various recommendations, including other products this product is frequently bought with, other products bought by customers who bought this product, and other products viewed by customers who bought this product Alternative purchasing options When using a monolithic application architecture, a mobile client would retrieve this data by making a single REST call GET api.

Is this even the right approach at all? The various gateways may set control headers that you want to look out for in your code e.

Building Microservices: Using an API Gateway

I’m looking to use Apigee or similar to handle all the dirty details security, throttling, ect. Make sure the set of backend endpoints you have scale with the traffic that passes through. It handles other requests by invoking multiple backend services and aggregating the results.

Each microservice would have a public endpoint https: Stack Overflow works best with JavaScript enabled. At it’s core an API Proxy should take care of throttling, analytics logging, key enforcement, some of the security and potentially load balancing across backend nodes.

You can also set quotas based on the API Key different developers getting different levels of access based on the products you associate with their keys.

It also simplifies the client code. The ability to cache responses in Apigee drives a lot of the rest of “where to do it” questions. Michael Geiser Invent 1 real-time applic. The zpigee would then query various database tables and return the response to the client. You may also want rules to block unexpected responses from the target server errors that may contain stack traces for example.

The Apigee 4G stack is amazing! In more complex applications it might have to make many more. Where to put functionality in the flow is usually contextual but there are a few easy things to put in every proxy: Keep this field blank. Calls to this back-end will be exclusively through proxy Apigee. It might even use multiple implementations of each style. This reduces the number of round trips between the client and application.

If you are using the JVM you should definitely consider using Hystrix. Sign up using Facebook. Santanu Dey 1, 1 14 Where to put functionality in the flow is usually contextual but there are a few easy things to put in every proxy:. Watch the videos here: The client in this example has to make seven separate requests.

Writing API composition code using the traditional asynchronous callback approach quickly leads you to callback hell. Ask us a question.

A system will typically use both asynchronous and synchronous styles. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

I’m very impressed with their implementation on many level BTW: For example, we might merge two services or split a service into two or more services. Only a handful of companies operate at the scale of Netflix and need to handle billions of requests per day.
