Throughout this book, we will build a useful SaaS application called MyEvents. MyEvents will utilize the technologies that you'll be learning in order to become a modern, scalable, cloud-native, and snappy application. MyEvents is an event management platform that allows users to book tickets for events all over the world. With MyEvents, you will be able to book tickets for yourself and your peers for concerts, carnivals, circuses, and more. MyEvents will keep a record of the bookings, the users, and the different locations where the events are taking place. It will manage your reservations efficiently.
We will make use of microservices, message queues, ReactJS, MongoDB, AWS, and more to construct MyEvents. In order to understand the application better, let's take a look at the logical entities that our overall application will be managing. They will be managed by multiple microservices in order to establish a clear separation of concerns and to achieve the flexibility and scalability that we need:
We will have multiple users; each User can have multiple bookings for events, and each Booking will correspond to a single Event. For each one of our events, there will be a Location where the event is taking place. Inside the Location, we will need to identify the Hall or room where the event is taking place.
Now, let's take a look at the microservice architecture and the different components that make our application:
We will use a ReactJS frontend to interface with the users of our applications. The ReactJS UI will use an API gateway (AWS or local) to communicate with the different microservices that form the body of our application. There are two main microservices that represent the logic of MyEvents:
- Event Service: This is the service that handles the events, their locations, and changes that happen to them
- Booking Service: This service handles bookings made by users
All our services will be integrated using a publish/subscribe architecture based on message queues. Since we aim to provide you with practical knowledge in the world of microservices and cloud computing, we will support multiple types of message queues. We will support Kafka, RabbitMQ, and SQS from AWS.
The persistence layer will support multiple database technologies as well, in order to expose you to various practical database engines that empower your projects. We will support MongoDB, and DynamoDB</span>.
All of our services will support metrics APIs, which will allow us to monitor the statistics of our services via Prometheus.
The MyEvents platform is designed in a way that will build strong foundations of knowledge and exposure to the powerful world of microservices and cloud computing.
