Notification Service

Functional Requirements:

• Ability to Send Notifications: The first thing the system should be able to do is send notifications.
• Pluggable: It means we should be able to add the new features without making a lot of changes to the system.
• SaaS: It should be built as a SaaS product. This is because the main idea is we should know who’s sending what number of notifications, and we should be able to rate limit.

Non-Functional Requirements:

• High Availability: The notification service system platform should always be available because it can be used by other companies, then downtime would cost us a lot.
• Many Clients: Moreover, it should be built in a way that it’s easy enough to add more clients.
