Customer Challenge
To ensure the client requirements, this notification solution must be flexible, reliable, traceable, configurable and easily integrated with other clients’ systems or modules.
Proposed solution
We proposed cloud-based notification solution by leveraging AWS serverless services: API Gateway, Lambda, SQS, SNS, S3 Bucket, and DynamoDB to deal with customer challenges.
The API Gateway is configured to securely receive HTTP requests and send HTTP responses to the front-end. A lambda (Producer) is implemented to push messages into SQS used as data storage. Other lambdas (Consumers) will pull these messages to fulfill some business requirements. For example, a lambda is triggered automatically to read the messages from SQS and send emails to list of users configured in a SNS. To ensure reliability, the SQS is configured to retry undelivered messages in a dead-letter queue following each failure.
The S3 Bucket is used to store JSON templates that will be used to generate dynamically emails and SMS with information (destination, subject, text, etc.) in real time. To ensure traceability, a DynamoDB is used to store the status (sent, received, failed) for historic, statistic, auditing and troubleshooting purposes.
Results & mprovements
These AWS serverless services allow the implementation of real-time notification service with flexibility, traceability and reliability while reducing hosting, management and maintenance costs.
After the integration of this notification system in the clients’ ecosystem, the internal users can receive multiple notifications by SMS and emails according to the user’s profile and some other criteria.

The search engine is critical for the client from a business perspective. The current solution is to perform research queries directly in RDS SQL Server database.
Managing files and images effectively is crucial for the business client, however, this task brings new challenges related to the integration with existing systems.
