Microservice Design Considerations

1. Authentication Management

• User Registration

  

• User Login with credentials, set non-critical user data into local storage

  

• User Logout

2. Tutoring Functionalities

• Student search for tutors based on subjects of interest

  

• Student apply for tutoring

  

• Student/Tutor get all applications sent/received

  

• Tutor accept/deny tutoring applications

  

3. Chatroom

• Create chatroom once tutor accepts application

• User get a list of created chats

• User send message in a specific chatroom

  

4. Payment

• User make payment for tutoring session

  

5. Subjects

• Get a list of subjects, with the ability to specify between all, psle, olevel and alevel

Cloud Native Design, Architecture Rationale and Resiliency

• Cloud Reliability by replicas being set to 3; In the case that any of the pods go down, another one will be reinstated in place of the previous.
• Cloud Scalability through Google Cloud, where auto-scaling is set to listen to CPU usage to tune up/down the number of resources being deployed.
• Cost-effectiveness that ties in with scalability, as resources are only instantiated when necessary and taken down when no longer necessary.
• Agility through the use of rolling updates to replace old versions of the application with new ones with no disruption and no downtime to users.
• Portability through ease of deployment on other cloud services (so on this occasion, we utilised Google Cloud).

Development Tools & Methods

Get Smart Tutoring was developed using the following tools:

• Developed using Microservice architecture, specifically for the Golang backend.
• Back-end: Golang server using Mux Router
• Front-end: React.js & Bootstrap
• CORS Middleware Tool: Moesif Origin & CORS Changer (Used for testing)
• CORS Middleware Package: rs/cors - GO Package
• Database: Firebase
• Cloud deployment: Google Cloud using Kubernetes Engine
