The document outlines the etiquette and expectations during AWS API Gateway sessions, including punctuality and constructive feedback. It explains what an API Gateway is, along with various use cases and scenarios demonstrating its functionality, particularly in AWS. Additionally, it describes Amazon API Gateway as a managed service that facilitates the creation, monitoring, and security of APIs at scale.

- 2. Lack of etiquette and manners is a huge turn off. KnolX Etiquettes Punctuality Join the session 5 minutes prior to the session start time. We start on time and conclude on time! Feedback Make sure to submit a constructive feedback for all sessions as it is very helpful for the presenter. Silent Mode Keep your mobile devices in silent mode, feel free to move out of session in case you need to attend an urgent call. Avoid Disturbance Avoid unwanted chit chat during the session.

- 5. What is API Gateway An API Gateway is a server that acts as an API front-end, receiving API requests, enforcing security policies, passing requests to the back-end service, and then passing the response back to the requester. It acts as a reverse proxy to accept all application programming interface (API) calls, and aggregate the various services required to fulfill them, and return the appropriate result.
- 6. Use Cases for API Gateway 02
- 7. Platform Validation: − Scenario: An e-commerce platform requires all incoming product image uploads to be in a specific image format (e.g., JPEG or PNG) and below a certain file size to ensure consistency and minimize storage costs. The API Gateway validates incoming images and rejects those that don't meet the criteria. Allow/Deny List: − Scenario: A financial institution allows access to its banking API only from specific partner organizations' servers by IP address. The API Gateway maintains a whitelist of trusted IPs while blocking all other incoming requests. Authentication and Authorization: − Scenario: A healthcare application requires users to log in with their credentials. Once authenticated, the API Gateway checks user roles and permissions to determine which medical records and services they can access. Service Discovery: − Scenario: In a containerized microservices environment, the API Gateway relies on service discovery to route client requests to the appropriate version of a service. When a new version is deployed, the API Gateway automatically updates its routing.
- 8. Dynamic Routing: − Scenario: A content delivery service uses dynamic routing to handle traffic for different types of content. Requests with "/videos/" in the URL path are routed to video-serving microservices, while those with "/images/" go to image servers. Rate Limit: − Scenario: A public API that provides weather data imposes rate limits to prevent a single client from making too many requests in a short period. The API Gateway monitors request rates and enforces rate limits, ensuring fair access for all users. Protocol Conversion: − Scenario: A messaging platform uses an API Gateway to convert HTTP requests from web clients to WebSocket protocol for real-time chat functionality, enabling seamless communication between web and mobile clients. Error Handling: − Scenario: An online marketplace API, when encountering errors like a product being out of stock, returns meaningful error responses to the client, including information about when the product will be available again, helping customers make informed decisions.
- 10. What is AWS API Gateway Amazon API Gateway is a fully managed service provided by Amazon Web Services (AWS) that allows developers to create, publish, monitor, and secure APIs at any scale. Like all API Gateways, it also acts as a front door for applications to access data, or functionality from backend services, both within the AWS environment and externally. Amazon API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including: − API Creation and Deployment − Traffic Management − authorization and access control − Security and Access Control − Monitoring and Analytics − Integration and Transformation − Developer and Partner Portals − API Lifecycle Management

- 12. How API Gateway helps: Serverless Architectures: Use Case: Building serverless applications using AWS Lambda. Web and Mobile Applications: Use Case: Building backend APIs for web and mobile applications. Third-Party Integrations: Use Case: Integrating with external services and partners. Real-time Applications: Use Case: Building real-time applications such as chat applications or collaborative tools. Content Delivery and Aggregation: Use Case: Aggregating content from various sources and delivering it to clients.
