High Level Application Architecture
Application has been developed using LAMP (Linux, Apache, MySQL, PHP) technology stack. PHP based MVC framework YII2 has been used to develop the application.
This is a SaaS application developed using a Multi-tenant database. The DB has been architected using single shared DB per tenant architecture. There is logical separation in client data based on client based identifier in the DB tables.
A single, shared database schema
A schema is a layout for database tables that relate to each other. In the first approach, one database is used with tenant tables all linked to the database. The tables handle relations and version control or updates, such as handling two people attempting to manipulate the same table or data entry. This is the fastest way to operate, since only one database is being used, assuming it scales.
Application is hosted on AWS infrastructure.
- Application/ Web server is hosted on EC2 instance
- MySQL DB is hosted on RDS
- Application uses SSL for information encryption on the network.
