Cloud Endpoints Framework For The App Engine Standard Environment.

 

What is an API and how it works?

API is nothing but Application programming interface. It is software intermediary it allows two applications to talk to each other. Every time you use many apps, send an instant message or check the weather on your laptop and phone you are using an API. When you use an app on your mobile phone, the app connects to the internet and sends data to a server. The server can find that data, interpret it and perform some actions, and sends it back to your phone. The application then receives that data presents you with the information in a readable way. This is what an API is and all of this happens .

API Management

The ESP provides API management features for Endpoints for OpenAPI. ESP operate in a container alongside each instance of your backend.

Because the App Engine standard environment did not support multi-container deployments when Endpoints Frameworks was under development, Endpoints Frameworks does not use ESP. Instead, Endpoints Frameworks includes a built-in gateway that provides API management features that are comparable to the features that ESP provide for Endpoints for OpenAPI and Endpoints for gRPC.

Endpoints Frameworks grab all requests and performs any necessary checks (such as authentication) before forwarding the request to the API backend. When the backend responds, Endpoints Frameworks gathers and reports telemetry. You can view metrics for your API on the endpoints service page in the Cloud Console.

You can use Endpoints Frameworks with and also without API management functionality. Use of Endpoints Frameworks without any API management functionality is offered at no charge.

 

There are some limitations: -

  • Endpoints Frameworks is the only supported on the App Engine standard Python and Java runtime environments.
  • Endpoints Frameworks does not support the only Node.js, PHP, and Go runtime environments on the App Engine standard environment.
  • Endpoints Frameworks does not support the App Engine flexible environment.
  • Endpoints Frameworks does not support Cloud Functions, Compute Engine, and Google Kubernetes Engine.

Cloud Endpoints for gRPC

Image
Google's gRPC is a high-performance, open-source universal RPC framework. A client programme can call methods on a server application on another machine as if it were a local object using gRPC, making it easier to construct distributed applications and services. Overview: A client programme can call a method on a server application on another machine as if it were a local object using gRPC, making it easier to construct distributed applications and services. gRPC, like many RPC systems, is built on the concept of creating a service, which includes describing the methods that may be called remotely, as well as their parameters and return types. On the server side, this interface is implemented and a gRPC server is used to process client requests. On the client side, the client has a stub (in some languages referred to as just a client) that provides the same methods as the server. One of the main advantages of gRPC is that it allows you to build reference documentation for your API ...

Cloud Endpoints: The Review

Brief about Cloud Endpoints  Cloud Endpoint   Cloud Endpoints is a tool that assists you in developing, deploying, securing, and monitoring APIs on Google Cloud Platform. Endpoints is an API management solution that consists of services, run-times, and tools. Endpoints manage, monitor, and authenticate users.  Endpoints can be used with either the distributed Extensible Service Proxy (ESP) or the Extensible Service Proxy V2 (ESPv2). Each proxy gives assistance to the platforms listed below: App Engine flexible (ESP only) Google Kubernetes Engine (ESP or ESPv2) Compute Engine (ESP or ESPv2) Kubernetes (ESP or ESPv2) App Engine standard (ESPv2 only) Cloud Functions (ESPv2 only) Cloud Run (ESPv2 only) Cloud Run for Anthos (ESPv2 only   Feature of Cloud Endpoints: User Authentication API keys Automated Deployment Easy Integration Logging and Monitoring Lightning Fast   Endpoints Architecture: Cloud Endpoints Architecture   Endpoint Components: 1.
