Description

In this project, we are working on part of a larger logistics system. This system handles

requests for package delivery from multiple providers, offering specialized services for

different types of shipments, such as standard delivery, express delivery, and international

delivery. The focus is on situations where customers need to schedule a package pickup

and delivery service.

Here$$s how it works:

$1.$ When a customer wants to send a package, they submit a request to the central

logistics service through Kafka as a middleware. This request includes details such

as the type of shipment $($standard$,$ express, international$),$ pickup location, delivery

location, preferred time slots, and customer information $($first name, last name,

contact number$).$

$2.$ The logistics service processes the request and communicates with various delivery

services $($standard$,$ express, international$)$ to find the best available time for the

pickup and delivery based on the customer$$s preferences. These delivery services

may need to coordinate to determine the optimal route and schedule, especially for

international deliveries.

$3.$ Once the pickup and delivery times are confirmed, the logistics service sends the

complete details back to the customer, including tracking information and estimated

delivery time.

Your job is to create and set up this logistics sub$-$system.

Important things to note:

a$)$ The system should be designed using a microservices architecture with a central

logistics service and three specialized services: standard delivery, express

delivery, and international delivery.

b$)$ Use a Kafka instance to support the communication between the client and the

various services.

c$)$ Use a data store such as MongoDB or SQL to store customer information,

shipment details, and delivery schedules.

d$)$ Finally, deploy each service $($logistics$,$ standard, express, and international

delivery$)$ in separate Docker containers.

Evaluation Criteria:

$$ Setup of the Kafka cluster, including topic management. $(30$ marks$)$

$$ Setup of the MongoDB$/$SQL database instance. $(10$ marks$)$

$$ Docker container configuration. $(10$ marks$)$
