Cloud computing is a technology for delivering ubiquitous, appropriate, on-demand networking access to shared computing resources and services that can be quickly equipped and supplied with minimal maintenance or service provider engagement. Amazon, with its Amazon Web Services (AWS) business, is at the forefront when it comes to providing cloud computing services around the world. The previous email solutions are entirely adequate when having to send a couple of dozen emails manually but don’t work when need to send out thousands of emails over the same time and take more time to send manually and unverified email addresses cause security issues. Serverless microservice architecture is used in the proposed work to implement a cloud-based messenger service using Springboot Framework and Amazon Web Services. AWS Lambda, Elastic Compute Cloud, Simple Queue Service (SQS), Simple Notification Service, Simple Storage Service (S3), Simple Email Service (SES), and cloudwatch are some of the Amazon Web Services used in the implementation to send bulk emails with less time using email templates and configure services to monitor the email. The proposed work is implemented as followed: The vehicle or applications will send a message scheme over SQS for an email to be sent. The templates inside the SES bucket will be transferred through Lambda to the S3 payload bucket. The specific template will be formatted with the message. Then the SQS event will trigger Lambda. The lambda will start fetching messages from SQS and start formatting inside the Lambda, once the format is done it will start publishing to SES. Further, SES will transfer the email to the cloud as well as CloudWatch and SNS to keep track of email sends, deliveries, bounces, and complaints.
