This repository demonstrates the development of an ask a question app in 3 different software architectures:
- Monolithic
- Service-oriented architecture (SOA)
- Microservices
In each of those architectures the application gives the same user experience from the frontend environment, but is designed following the corresponding architecture patterns from those 3 famous architectures.
To create this app the following technologies were used:
- React JS for the frontend environment
- Node JS and Express framework to develop the backend environment
- Redis for messaging between the microservices
- PostgreSQL as the database system
The different architecture choises that were made for each of the 3 architectures, can be seen in the documentation folder. Apart from the vpp(Visual Paradigm) projects, there are some images that show those diagrams that were created.
The SOA and Microservices architecture where deployed on Heroku, using different apps for each one of the components. The databases were created in linode.com using a PostgreSQL image.
The different components of the microservices architecture can be seen in the component diagram below:
Similarly for the SOA, here is the component diagram:
