RFC-007: Appointment Booking System — Initial Design

Overview

The system allows patients to book, reschedule, and cancel appointments with their registered GP. Surgeries can manage their availability calendars and view their upcoming schedule.

Non-Functional Requirements

• The system must be highly available — appointment booking is time-sensitive and patients should always be able to access the platform.
• The system must be fast enough that patients do not experience frustrating delays when browsing available slots.
• The system must be secure.
• The system should scale to support more surgeries as the business grows.

Architecture

We will use a serverless architecture on AWS with API Gateway, Lambda, and DynamoDB. This gives us automatic scaling and we only pay for what we use.

Open Questions

• None identified at this time. The team is comfortable with the proposed approach.
