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 .

It might have other responsibilities such as authentication, monitoring, load balancing, caching, request shaping and management, and static response handling. Said API is fundamental to our apigew and all that.

It might even use multiple implementations of each style. With some fscade, such as a product details request, the requests to backend services are independent of one another. Performance and Scalability Only a handful of companies operate at the scale of Netflix and need to handle billions of requests per day.

Sign up using Facebook. Michael Geiser What I can’t quite find is a recommended list of things my back-end API server should do and more importantly, shouldn’t have to do using this strategy. No need to tell your app developers about your target architecture, but it’s sometimes hard to suppress those headers from application servers. The Apigee functionality is amazingly rich, blinding fast and lightweight with very little latency from the process.


Building Microservices: Using an API Gateway

Having said all this – I’d encourage you to check out 3scale – we provide equivalent services to Apigee including the API gateway. Over time we might want to change how the system is partitioned into services. Infrastructure services, such as a message broker, will usually have a static location, which can be specified via OS environment variables. You also want to set spike arrests to keep your API traffic from overwhelming your target server.

It implements a circuit breaker pattern, which stops the client from waiting needlessly for an unresponsive service. Here are some Best Practice type content that is generated by Apigee folks – however more importantly – these are NOT directly based on using Apigee Technology as such. I’m very impressed with their implementation on many level BTW: He now consults with organizations to improve how they develop and deploy applications.

Hystrix lets you define a fallback action when a request fails, such as reading from a cache or returning a default value. Make sure you strip out unnecessary response headers cookies, server versions, etc that aren’t relevant to facae API Contract. Stack Overflow works best with JavaScript enabled.

You may also want rules to block unexpected responses from the target server errors that may contain stack traces for example. It then routes requests to the appropriate microservice.

I’ll have my own client web-site and internal apps using the API as dogfood. Colin Fitzgerald 28 4.

Email Required, but never shown. In the next article in the series, we will look at communication between services.


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. 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.

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. Only a handful of companies operate at the scale of Netflix and need to handle billions of requests per day.

Make sure the set of backend endpoints you have scale with the traffic that passes through. If, however, clients communicate directly with the favade, then performing this kind of refactoring can be extremely difficult.

Also, the set of instances of a service changes dynamically because of autoscaling and upgrades. Consider, for example, the product details scenario. Chris Richardson apigew Eventuate, Inc. Hope that helps and happy to give more info if useful.
