Serverless Technologies

Embracing serverless technologies can significantly reduce operational complexity by eliminating the need to provision, manage, and scale servers for your applications. Serverless services automatically handle the underlying infrastructure, allowing you to focus on writing code and delivering business value.

In this lesson, we will cover:

• AWS Lambda :
  • Executes code in response to events.
  • Automatically scales based on the number of events.
• Amazon API Gateway :
  • Creates, publishes, and secures APIs.
  • Works seamlessly with AWS Lambda for serverless backends.
• Amazon EventBridge :
  • Serverless event bus for integrating applications using data from various sources.

AWS Lambda

AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You pay only for the compute time you consume, and there is no charge when your code is not running.

• Executes code in response to events**:**
  • Triggers can include changes in data, system state, or user actions.
  • Integrates with various AWS services such as S3, DynamoDB, Kinesis, SNS, and more.
• Automatically scales based on the number of events:
  • Lambda automatically manages the compute capacity required to run your code.
  • Scales seamlessly from a few requests per day to thousands per second.

Let's get started!

Amazon API Gateway

Amazon API Gateway is a fully managed service that makes it easy to create, publish, maintain, monitor, and secure APIs at any scale. It acts as a "front door" for applications to access data, business logic, or functionality from your backend services.

• Creates, publishes, and secures APIs:
  • Supports RESTful APIs and WebSocket APIs.
  • Provides features like traffic management, authorization and access control, monitoring, and API version management.
• Works seamlessly with AWS Lambda for serverless backends: *…
