A SaaS company offers a case management solution that includes sending acknowledgment emails to customers. Currently, they use a standalone SMTP server to send these emails, which include templates populated with customer data. They plan to migrate this functionality to AWS to reduce operational overhead. What is the most cost-effective solution for this migration?
Explanation:
The correct answer is D. By using Amazon Simple Email Service (SES) to send email messages, the company can leverage a fully managed service that handles the complexities of sending and receiving emails, thereby minimizing operational overhead. Storing the email template in SES with parameters for the customer data allows for easy integration. Creating an AWS Lambda function to call the SendTemplatedEmail API operation and passing the necessary customer data and email destination ensures automation and efficiency. This solution is both cost-effective and reduces the need to manage infrastructure, unlike options that involve setting up an SMTP server on Amazon EC2.
