1. Project Overview

1.1 Project Description

Our team has developed an event booking system. In the system, the users can browse, publish and book events. The system uses a robust cloud-based microservices architecture designed to handle various operations efficiently. It is deployed on aws using Kubernetes.

1.2 System Architecture

The architecture of the system can is described in the following graph:

It can be simply divided into four parts:

1. Istio Gate Way

2. User Verification 

3. Event operations

4. Data Storage

In our system, the backend is divided into to modules. User module and event module. In user module, there are login, register, token verification and order record microservices. In event module, there are event global data, event detailed data, event publish and booking microservices. The microservice communicate with each other using HTTP protocol. Besides, we also use Redis and RabbitMQ to synchronous data between microservices.

1.3 Key Components

• Microservices Architecture: Each service (Register, Login, Booking, Event Publish) is deployed as a microservice
• Istio Gateway: Manages external traffic, providing secure communication and traffic management capabilities.
• Service Mesh: Istio's service mesh capabilities enable secure, reliable communication between microservices, ensuring observability and policy enforcement.
• Routing by hash: We use an algorithm similar to consistent hash to divide the data into several databases. Then using service mesh to routing the requests by their hash.
• Data Storage: We use MySQL databases to store user and event data, structured to handle high volumes of transactions efficiently.
• Message Queuing: RabbitMQ is employed to manage asynchronous communication between services, ensuring reliable data transfer and processing.

2. Environment Setup

2.1 Prerequisites

List all the prerequisites needed to set up the environment.

Operating system: Ubuntu (Other OS may also work, but we have not tested on them)

Software and libraries:

• Istio
• Kubernetes Gateway API CRDs
• go version 1.22
• OperatorSDK

Please see 2.2 for more information.

2.2 Installation

Step-by-step guide to setting up the development environment. We assume you have:

• git
• docker
• AWS CLI
• Kubectl

Also, we assume that you have AWS Configured and ESK Cluster Setup.

1. Step 1: Istio.

   curl -L https://istio.io/downloadIstio | sh -
   cd istio-1.22.3
   export PATH=$PWD/bin:$PATH
   istioctl install --set profile=demo -y

2. Step 2: Kubernetes Gateway API CRDs.

   kubectl kustomize "github.com/kubernetes-sigs/gateway-api/config/crd?ref=v1.1.0" | kubectl apply -f -

3. Step 3: go version 1.21.

   wget https://go.dev/dl/go1.22.5.linux-amd64.tar.gz
   sudo tar -C /usr/local -xzf go1.22.5.linux-amd64.tar.gz
   export PATH=$PATH:/usr/local/go/bin
   source ~/.profile
   go version

4. Step 4: OperatorSDK.

   git clone https://github.com/operator-framework/operator-sdk
   cd operator-sdk
   git checkout master
   make install

3. Application Deployment

Detailed steps to deploy the application.

1. Step 1: Apply all the yaml files

   kubectl apply -f "$dir"

2. Step 2: Deploy the operator.

   make deploy

3. Or you can quickly start the project

   ./start.sh

4. Reference

Some of our backend and frontend code are referenced from a project in SUSTech course CS304.
