Frequently Asked Questions about AWS API GATEWAY

Yes, API Gateway supports versioning. API Gateway allows developers to version their APIs and manage different versions of the same API. This allows developers to deploy new versions of their APIs without impacting existing applications. Additionally, API Gateway allows developers to create multiple versions of the same API and enable or disable different versions as needed.

Yes, API Gateway supports API throttling. You can use API throttling to control the rate of incoming requests to your API and protect it from malicious or excessive traffic. You can configure throttling limits on a per-API basis and vary them by user, stage, or individual method.

API Gateway also provides features such as API keys, usage plans, throttling, and authentication, making it a powerful tool for managing access to your APIs. Additionally, API Gateway supports caching, logging, and monitoring, making it easier to troubleshoot and optimize your APIs.

Yes, API Gateway provides several methods to secure APIs, such as OAuth, SAML, and OpenID Connect. Additionally, API Gateway provides a variety of other security features such as rate limiting, throttling, and IP filtering.

The cost of API Gateway varies depending on usage, but the base cost is typically between $3 and $5 per million API calls.

When creating an API stage, you can specify a version label that will be used to identify the version of your API. You can deploy different versions of your API to different stages, allowing you to control which version is currently active. You can also use the stage to manage access to different versions of your API.

This allows developers to easily create, manage, and deploy applications without having to manage the underlying infrastructure. Additionally, API Gateway can be used to securely connect applications and services hosted outside of AWS using open standards such as HTTP and WebSocket.

You can do this by creating an API Gateway deployment in each region, and then configuring the API Gateway to use one or more regional endpoints. Additionally, you can use AWS Lambda functions to enable cross-region communication between the different API Gateway deployments.

This enables real-time two-way communication between applications and devices. WebSocket APIs offer a persistent connection for real-time communication between clients and AWS services, and other applications. With WebSocket APIs, you can send and receive messages or events from the server in real-time without repeatedly polling for data. This allows you to create highly interactive applications that require real-time updates.

Yes, Amazon API Gateway supports auto-scaling. The service can scale up or down automatically in response to changes in demand.

The pricing for the API Gateway is based on the number of API calls made per month. The free tier offers up to 1 million API calls per month, with pricing for additional API calls ranging from $3.50 to $3.80 per million API calls. After the first million API calls, prices drop to as low as $1.00 per million API calls. Additional features such as caching, authorization, and metering are also available at an additional cost.

No, API Gateway does not provide a way to monetize APIs. API Gateway is an API management service that provides a way to create, publish, maintain, monitor, and secure APIs. Monetizing APIs would require additional services such as a payment gateway.

API Gateway also supports usage plans, which allow API publishers to control rate limits and quotas on API usage. API Gateway also provides a range of monitoring and logging features, including support for CloudWatch metrics, API request/response logging, and API request tracing.

Configure Authentication and Authorization: You will need to configure authentication and authorization for the API, such as API keys or OAuth., 4. Set Usage Plans: You will need to define usage plans, including the rate limits, quotas, and API keys for each plan., 5. Deploy Your API: Finally, you will need to deploy your API to make it available to the public.

1. REST APIs, 2. WebSocket APIs, 3. HTTP APIs, 4. Private APIs, 5. Open APIs, 6. Streaming APIs

Usage plans allow you to set up and manage rate limits and quotas for each API key or user. These plans also allow you to set up a pricing model for your API, charging for usage above a certain threshold. API keys allow you to authenticate and authorize access to your API, and provide an additional layer of security.

Yes, API Gateway supports API caching. It allows you to cache API responses for a period of time to reduce latency and improve performance. You can also configure the cache to be updated or invalidated based on conditions such as a specified time interval or when a backend API changes.

You can also use API Gateway to map custom domain names to other AWS services, such as Lambda functions and Amazon S3 websites.

You can use the API Gateway console, the AWS CLI, or the API Gateway SDK to create, publish, maintain, monitor, and secure APIs for serverless applications. Additionally, API Gateway provides features such as transformation, authorization, and request/response mapping, making it an ideal platform for developing and deploying serverless applications.

The dashboard provides information such as API request count, latency, error rate, and more. It also allows users to drill down into specific API calls to view details such as the source IP address, user agent, and response time. The dashboard also includes charts and graphs to help visualize API usage and performance.

AWS API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. With API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway handles all of the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, authorization and access control, monitoring, and API version management.

API caching helps reduce latency and load on the backend by caching API responses for a certain amount of time. API Gateway caches API responses on the edge and serves them to clients without having to invoke the API’s backend. This helps reduce the load on the backend and improves API performance.

It provides analytics on the number of requests processed, latency, and error rates, as well as the ability to trace individual requests through the system. This allows developers to quickly identify issues and make adjustments to improve performance.

You can also configure a custom domain to use a specific protocol (such as HTTPS). Additionally, API Gateway supports regional custom domains, which can be used to serve APIs from different regions.

API Gateway provides monitoring and analytics at the API level, allowing you to track performance, errors, and other key metrics. It also offers request tracing, enabling you to identify and debug issues quickly. Additionally, API Gateway also provides real-time monitoring, alerting, and analytics for API usage, latency, and errors, so that you can quickly identify and address any potential issues.

The Irsaal Al-Ma’aani or Commentary on the Quran was written by the Muslim scholar, Jalaluddin Suyuti. He was a prominent Shafi’ite scholar, who lived from 1445 to 1505. Suyuti wrote the Irsaal Al-Ma’aani in order to provide a comprehensive explanation of the Qur’an. As a part of the explanation, Suyuti discussed the various interpretations of verses of the Qur’an and provided his own explanations for them. He also often included references to related Hadith and other Islamic literature, in order to provide further support for his interpretations. The Irsaal Al-Ma’aani is still seen as one of the most important and influential commentaries on the Qur’an, and is still widely studied by Muslims today.

Yes, API Gateway supports API documentation. The API Gateway console provides a graphical interface to help you document your APIs. You can also use the API Gateway developer portal to automatically generate API documentation from your API definitions. Additionally, the API Gateway Developer Portal integrates with popular API documentation frameworks such as Swagger.

It allows you to cache the data returned from certain requests and responses so that subsequent requests for the same data are served from the cache instead of being sent to the backend. This can improve the latency of your API and reduce the load on the backend. You can configure caching policies on individual API methods and specify the TTL (time to live) for the cached data.

No, API Gateway does not provide a dashboard for monitoring API usage. However, API Gateway does offer metrics that you can use to monitor API usage, such as the number of requests, latency, and errors.
