Introduction
This serverless architecture diagram explains to fetch critical information from a file uploaded by a client like Aadhar Card, Pan Card, and Passport information asynchronously.
We used AWS Cloud services to build the architecture and those are given below –
AWS Services Information
AWS S3: To store File
AWS Database: To store metadata and other critical information
AWS Lambda: Write and Execute a Business Logic
AWS Step Function: Workflow and orchestrate the process
AWS SES: To Send an email communication
Lambda – 1 Function
- Validate the Files
- check File Size
- File format
- Virus Scan
- Insert Metadata
- Send an email if an error occurs in the files
- Invoke Step Function once a valid file uploaded
Lambda – 2 Function
- Read Data from the files
- Insert Data into the Database
- Send email Notification
Lambda – 3 Function
- Convert files for multiple devices like the Web, Mobile IOS, Android, etc.
- Save Files on S3 Bucket
- Save metadata in the database
