Run code without provisioning or managing servers.
Pay only for the compute time you consume; No charge when not
running
Execute for virtually any type of application or backend service
Simple: Upload your code; Lambda runs & scale code with high
availability.
Automatically trigger from other AWS services or call directly from
web or mobile app.

Let’s Dig DeepLooking at a Lambda Function
Amazon API Gateway
Simplified API
developmentPerformance at Scale Security Controls Monitor & meter
API activity
Makes it easy for developers to create, publish, maintain, monitor,
and secure APIs at scale.
With a few clicks, create an API that acts as a “front door” for
applications to access data, business logic
Tie API functionality to back-end services from Amazon EC2, AWS
Lambda, or any Web app
Handles traffic management, authorization and access control,
monitoring, and API version managemen for processingconcurrent

Sign in with
Your User Pools
You can easily and securely add sign-up
and sign-in functionality to your mobile and
web apps with a fully-managed service that
scales to support 100s of millions of users.
Federated Identities
Your users can sign in with third-party
identity providers, such as Facebook and
SAML providers, and you can control access
to AWS resources from your app.

Amazon Cognito:
Comprehensive Support for Identity Use Cases
Amazon Cognito User Pools: Comprehensive User Flows
Email or Phone
Number Verification
Forgot Password
User Sign-Up and
Sign-In
Require users to verify their email address or phone number prior to activating
their account with a one-time password challenge
Provide users the ability to change their password when they forget it with a
one-time password challenge
Allow users to sign up and sign in using an email, phone number, or username
(and password) for your application.
User Profile Data Enable users to view and update their profile data – including custom attributes
SMS Multifactor
AuthenticationRequire users to complete a second factor of authentication by inputting a
security code received via SMS as part of the sign-in flow
Customize these User Flows Using Lambda
Token Based
AuthenticationUse JSON Web Tokens (JWTs) based on OpenID Connect (OIDC) and OAuth 2.0
standards for user authentication in your backend
